Jaeger-LeCoultre highlights its expertise in celestial complications with an artistic reinterpretation of the Master Hybris Artistica Minute Repeater Cosmotourbillon, in a limited edition of five pieces. With a new 18K white gold (750/1000) case, this new opus celebrates the Maison’s artistic creativity and mastery of haute horlogerie decorative crafts while reaffirming its technical ingenuity. Originally created in 2010, Calibre 945 unites a star chart indicating the constellations in the Northern Hemisphere moving in real time, a minute repeater and Jaeger-LeCoultre’s unique flying Cosmotourbillon, which displays sidereal time.

ARTISTIC CREATIVITY: A STRIKING CELESTIAL AESTHETIC THANKS TO MÉTIERS RARES™

The new edition of the Master Hybris Artistica Calibre 945, reinterpreted in 18K white gold (750/1000), showcases the exceptional expertise of the Manufacture’s Métiers Rares™ atelier. Entirely hand-decorated by its artisans, the multi-level domed dial creates a striking sense of depth, bringing the celestial display vividly to life.

To recreate the beauty of the night sky, Jaeger-LeCoultre employs grisaille enamel, a rare decorative art introduced into the Maison’s repertoire in 2022. Originating in 16th-century France, this demanding technique builds delicate chiaroscuro effects through successive layers of enamel, each individually fired. The deep blue background is gradually composed before the celestial motif is painted by hand using a white enamel known as Blanc de Limoges, creating subtle contrasts and a remarkable illusion of three-dimensional depth.

Echoing the dome of the night sky above us, the dial is constructed on multiple levels. A midnight-blue disc, finished with translucent lacquer over opaline, forms its deepest layer and carries the months and tourbillon seconds indications. Above it, the domed gold dial is decorated with grisaille enamel depicting the celestial landscape, while the star chart and constellation names are delicately transferred onto its surface. Together, these elements create an immersive interpretation of the heavens, with the tourbillon seconds scale radiating from the Cosmotourbillon like beams of light.

INTERPRETING THE HEAVENS: THE COSMOTOURBILLON AND CELESTIAL TIME

Elevating time through celestial mastery: evolving the tourbillon beyond its purely technical function as a regulating mechanism designed to defy gravity, Jaeger-LeCoultre has created the Cosmotourbillon. A celestial flying 60-second tourbillon, it also measures the passing of time by completing an anti-clockwise circuit of the dial in one sidereal day. Lasting 23 hours, 56 minutes and 4 seconds, a sidereal day corresponds to Earth’s rotation relative to the fixed stars, whereas the 24-hour solar day, used for civil time, is defined by the Earth’s rotation on itself, compared to the Sun. It moves in harmony with the Northern Hemisphere sky chart, which tracks the real-time positions of the constellations as seen from Switzerland’s Vallée de Joux, Jaeger-LeCoultre’s home since 1833.The flying Cosmotourbillon is secured on the movement side only, revealing its full kinetic beauty. Comprising 73 components, the entire mechanism is held within a lightweight titanium carriage, ensuring an unobstructed view of the regulating organ. Mounted on lubricant-free ceramic ball bearings, its 10-millimetre monometallic balance wheel beats at a frequency of 4 Hz.

In line with Jaeger-LeCoultre’s commitment to functional precision, the celestial display is driven by a calendar complication enabling the precise setting of the constellation positions as they appear in the sky. Indicated by a golden sun-shaped pointer at the edge of the rotating dial, it completes a full revolution in 24 hours, marking civil time.

THE SOUND OF THE HEAVENS: A MINUTE REPEATER MARKS TIME

Powerful chime with extreme purity: the exquisite chimes of a minute repeater complement the romance of celestial timekeeping and so this exceptional timepiece also takes Jaeger-LeCoultre’s expertise in chiming watches – one of the most challenging and rewarding of all horological complications for a watchmaker to master – to new heights by uniting the astronomical complications with it. The technical difficulty of creating a minute repeater lies in the complexity of the mechanism needed to transcribe the precise time shown by the hands into a series of perfectly programmed strikes with different sounds for hours, quarters and minutes. The artistic challenge is that the chimes must be pure, harmonious and clearly audible.

At Jaeger-LeCoultre, this continuing quest for the ideal sound has produced several patented innovations – at least five, including Cathedral crystal gongs wrapping 1.5 times around the calibre and fixed to the rear sapphire crystal for maximum resonance and as an amplifier of sound. Trébuchet hammers also patented, that vastly improve the acoustic qualities of the striking mechanism, stronger chime – the hammer shank is cut in half to give even more energy to strike twice more strongly on the gong obtaining an even stronger sound. A patented silent governor is here so there is no distraction from the crystal-clear sound of the magical mechanism.

In the minute repeater mechanism of Calibre 945, these inventions contribute a special magic that complements the romance of celestial timekeeping.

THE COMPLEXITY OF SIMPLICITY: AN EXCEPTIONAL CASE FOR A REMARKABLE WATCH

The case is a perfect complement to the artistic dial and mechanical sophistication of the Master Hybris Artistica Calibre 945. Measuring 45 mm x 16.05 mm and comprising more than 80 parts, its convex bezel is complemented by broad bevels on the lugs, while micro-blasted finishes inside the lugs add dynamic tension; the repeater slide is tapered to harmonise with the curving case sides. Different surfaces are micro-blasted, polished and satin-brushed to maximise the play of light and emphasise the details. Enhancing both aesthetics and ease of use, the watch has no recessed buttons in the side of the case for setting: all functions and displays are set via the crown. The minute repeater is activated by a slide on the left side of the case.

The watch is presented on a blue alligator strap with small-scale lining, carefully matched to the colour and texture of the dial. Completing the design, the 18K white gold (750/1000) folding clasp features a patented double-wheel adjustment mechanism, allowing precise adjustment in 0.5 mm increments for optimal comfort on the wrist.

The essence of the Master Hybris Artistica Calibre 945 lies in the way it artistically and visually interprets astronomical timekeeping for the wrist, using the dial to display our link to the cosmos on both literal and philosophical levels, combining mechanical creativity with intricate decorative crafts.

Jaeger-LeCoultre presents the Duometre Grande Complication A Grande Sonnerie, a new interpretation of Calibre 182, the Maison’s first chiming Grande Complication for the wrist. Introduced in 2009 in the Hybris Mechanica A Grande Sonnerie, Calibre 182 broke new ground in watchmaking. Incorporating a Grande Sonnerie with Westminster-style chimes – the most rarefied of all chiming mechanisms – a Petite Sonnerie and a Minute Repeater, as well as a retrograde perpetual calendar, flying tourbillon and two power reserve indicators – it was not only one of the most complicated wristwatch ever made at the time but also harnessed the innovative Duometre system (invented by Jaeger-LeCoultre in 2007) to manage the calibre’s extreme demands for energy. Due to the extreme complexity of Calibre 182, very few examples were made: with some 1,300 parts, it takes a full year only to assemble and regulate the movement and involves four phases with a total of 16,000 different operations: assembly; disassembly; corrections and cleaning; final assembly.

Now, with benefit of significant technical advances, focusing on improving the acoustic quality of the chimes and enhancing the robustness of the movement, Jaeger-LeCoultre presents a new interpretation of Calibre 182. The subject of eight patents, including six for developments specific to Calibre 182, the fully integrated movement incorporates 15 complications. The watch carries a ninth patent, for the micro-adjustment mechanism on the buckle of the alligator strap.

HARNESSING A GREAT LEGACY IN CHIMING WATCHES

The Watchmaker of Watchmakers™: For more than 150 years, chiming watches have been a particular forte of Jaeger-LeCoultre, complementing its renowned expertise in other classic complications, the Maison has developed more than 200 different chiming watch calibres, mastering all forms from relatively simple alarms to Grandes Sonneries and Westminster chimes. After creating its first minute repeater in 1870, Jaeger-LeCoultre became known as The Watchmaker of Watchmakers™️, supplying chiming movements to many of the most exalted names in watchmaking while continually innovating to improve the mechanical efficiency, clarity and beauty of its sound, from cathedral gongs and the silent strike governor to crystal gongs, trebuchet hammers and duplex gongs. Today, the Grande Sonnerie represents the ultimate sonnerie challenge, chiming every hour and quarter hour automatically while demanding exceptional power management, precision and mechanical complexity, placing it at the pinnacle of complicated watchmaking.

CALIBRE 182: 15 COMPLICATIONS BUILT ON THE DUOMETRE CONCEPT

To create the original Calibre 182 required more than five years of intensive research and development – harnessing the Manufacture’s preceding century-and-a-half of accumulated savoir-faire in chiming watches. Offering three different ways of chiming time, Calibre 182 unites this highly complex striking mechanism with a perpetual calendar indicating the date, month and day of the week in retrograde displays and the leap years in a digital display at 12 o’clock on the dial. Like all perpetual calendars, it automatically accounts for months of different lengths as well as leap years and, if it remains wound, will need no manual adjustment until 2100 (a century year that is not also a leap year.) The calibre is enhanced by a flying tourbillon regulator and features two distinct power reserve displays – one for each of the main barrels.

Two independent energy sources: Due to the critical importance of power management, a dual-barrel movement architecture is a crucial to a Grande Sonnerie calibre. For Jaeger-LeCoultre, it was natural to build Calibre 182 on the Duometre mechanism, which it invented in 2007. This concept resolves a fundamental conundrum of watchmaking: how to maintain a perfect flow of energy to ensure precise timekeeping while adding complications that require extra bursts of energy – which inevitably compromise that regular flow. A Duometre mechanism has two barrels, each with a separate and independent gear train, housed within a single calibre and linked to a single regulating organ. In the case of Calibre 182, one barrel provides energy to the gear train that powers the time and perpetual calendar indications and the other to the gear train that drives the chiming functions, thus ensuring that their operation has no impact on timekeeping accuracy.

The barrel dedicated to the timekeeping and calendar functions provides a 48-hour power reserve; the barrel dedicated to the chiming mechanism provides sufficient power in Grande Sonnerie mode for a total of 616 notes (equivalent to seven hours and 30 minutes of continuous chiming) and in Petite Sonnerie mode for a maximum of 992 notes – equivalent to 32 hours of chiming. In addition to the standard two-barrel Duometre configuration, Calibre 182 has a third barrel. It replaces the trigger's winding motion, since the latter is replaced by a push-button on the crown.

THE CHIMES: DISTINCTIVE MELODIES WITH ENHANCED TONAL QUALITIES

Three ways to chime: Because Calibre 182 is fitted with four gongs and four hammers — instead of the usual two gongs in minute repeaters and most sonnerie movements — it is able to play four different notes (in various combinations) in the manner of the Westminster chime – the famous melody of London’s Big Ben. Adding to the distinctive character of Calibre 182, Jaeger-LeCoultre’s watchmakers made the unusual choice to have the Grande Sonnerie and the Petite Sonnerie sound the quarter-hour melody first, followed by the corresponding hours; conversely the minute repeater follows the standard sequence of hours, quarters and minutes.

616 notes, 7 and a half hours: Calibre 182’s four notes – E, C, D, G (mi-do-re-sol); one for each of the four gongs – are played in five phrases of different permutations, which are then combined in different ways to provide a unique melody for each quarter-hour. The first quarter melody comprises four notes (one phrase); the second quarter eight notes (two four-note phrases) and the third quarter 12 notes (three four-note phrases). Thus, in Grande Sonnerie mode, the hour melody comprises six phrases of four notes each – a total of 24 notes, one of the longest Grande Sonnerie melody played by any watch incorporating a striking mechanism.

Since it is fundamental to Jaeger-LeCoultre’s horological approach to continually upgrade existing calibres, further technical development of Calibre 182 has focused on the quality of the chiming melodies. In a striking watch, the shape of the gongs is crucial to the tonal purity and resonant frequency of the chime, an area in which Jaeger-LeCoultre’s chiming-specialist engineers and watchmakers constantly seek improvements. The new version of Calibre 182 has advanced acoustic performance through a combination of improvements: the gongs have been lengthened for greater resonance, their fixing and tuning have been refined and the gong shape has been modified, while the inner case body and caseback bezel are now crafted in titanium, together enhancing the overall strength, beauty and depth of the sound. Every chime is, in fact a chord and every chord has a fundamental note, supplemented by other notes. Normally, by tuning the gongs, a watchmaker can vary only the fundamental note. Thanks to the minuscule change in the gong shape in Calibre 182, it has been possible to adjust both the fundamental note and the six other notes that make up the chord, thus creating a more melodious sound.

ADVANCED MECHANISMS, IMPROVED SECURITY AND INTUITIVE OPERATION

The information behind every chime: the functional heart of a chiming watch is its information-gathering system, made up of components known as snails and racks, which translate the position of the hour and minute hands into a corresponding number of strikes. In Calibre 182, two key mechanisms control its distinctive chiming sequences and melodies.

Precision behind every strike: The ‘tour d’entraînement de sonnerie’ or ‘strike sequence governor’ is a tower-shaped mechanism that provides the mechanical information to the racks, enabling them to move into the positions required for the chimes to strike in the correct sequence. According to the selected mode, the Grande Sonnerie and Petite Sonnerie sound the melody first, followed by the hours; conversely, the minute repeater follows the standard sequence of hours, the quarter-hour melody and minutes. This tiny mechanism, visible on the dial side between 8 and 9 o’clock position on the dial, comprises 22 components but is only 6.04 millimetres high.

A second tower mechanism – nicknamed “tour infernale” by Jaeger-LeCoultre’s watchmakers because of its complexity – governs the six permutations of the four notes that create the different melodies. This stack of five snails provides the racks with the information about which of the quarter melodies should be chimed in Grande or Petite Sonnerie mode, as well as the number of hours and minutes to be struck in minute repeater mode.

Intuitive control, exceptional complexity: Because chiming mechanisms are vulnerable to damage caused by misuse, Jaeger-LeCoultre’s engineers equipped Calibre 182 with a selector mechanism to ensure that the mode chosen by the user at any given time effectively ‘disables’ the other modes. This is indicated by a display at the 6 o’clock position on the dial: M for mise à l’heure (time setting) and three chiming modes – G Grande Sonnerie, P Petite Sonnerie and S silence (which silences the automatic sonnerie chimes but allows the minute repeater to be triggered on demand). In the latest version of Calibre 182, this is supplemented by a new security mechanism for the minute repeater mode that prevents the user from triggering the chime again before the mechanism has ‘reset’ on completion of a previous chiming sequence.

The operation of the various complications is governed by three pushers – two set into the caseband and the third set into the crown – ensuring that, despite its complexity, the watch is intuitive to read and use. Calibre 182 provides energy to the minute repeater directly from the movement; therefore, rather than requiring a traditional slide in the caseband that ‘charges’ the repeater’s mainspring, the minute repeater is simply operated by the pusher in the crown. The pusher below the crown acts as the chiming mode selector, indicated on the dial by G, P or S for silent/minute repeater. The normal functions of the crown are also governed by this selector, rather than by pulling the crown into different positions: to wind the watch, the user selects S (which ensures that the automatic, en passant, chiming functions are disabled) and to set the time, the user selects the fourth mode, M – mise à l’heure. The pusher above the crown enables correction of the perpetual calendar day indication. The month and date correctors are concealed between the lugs at 12 o’clock.

A NEW AESTHETIC COMPLEMENTED BY HAUTE HORLOGERIE FINISHING

The dial of the new Duometre Grande Complication A Grande Sonnerie is more open-worked than that of its predecessor, revealing more of the beauty and intricacy of the mechanism, while the diameter of the hour-minute-calendar dial has increased by 30 percent to enhance legibility and add balance to the composition.

The principal dial-side and the hour-minute-calendar dial are decorated with dark blue-grey lacquer, which provides a visually sober contrast to the myriad moving parts and pink gold aesthetic – the latter being applied to several components, notably the five racks and their corresponding springs, visible between the 10 and 11 o’clock positions. The centre of the hours-minutes dial is sunray brushed beneath the lacquer and on the outer circle, gradient dark blue lacquer applied over a sunray guilloché provides the background for the applied 18k Pink Gold (750/1000) hour indexes.

On the periphery of the watch face, the retrograde date indication forms an arc from 7 o’clock to 11 o’clock, laser-engraved on pink gold; the retrograde displays of the days of the week and the months are laser-engraved on a pink gold inner ring on the hour-minute dial, each indicated by a small golden arrow. The two power reserve counters characteristic of the Duometre architecture are open-worked and the leap year display at 12 o’clock, provides symmetry with the chiming mode indicator at 6 o’clock. On the reverse side of the watch, the sapphire crystal case back reveals the flying tourbillon, complemented by meticulous Haute Horlogerie finishing across the movement, including sandblasting, perlage, snailing, 87 hours of hand bevelling work on 251 components, sunk rubies and screws, sunray Côtes de Genève, flat polishing, linear brushing and circular brushing – nine distinct finishes in total.

Echoing the complexity of the movement, the Grande Tradition case is made up of 60 components, combining a titanium case body with 18k pink-gold (750/1000) elements including the lugs, bezel and pushers. The pink-gold components feature a combination of microblasted and polished finishes. The Duometre Grande Complication A Grande Sonnerie is set in a 45 mm case – a remarkable feat of miniaturisation for a 1,300-component calibre – complemented by a black alligator leather strap with the Hybris series’ signature folding buckle that features a patented mechanism to enable fine adjustment for a perfect fit on the wrist.

Reaffirming Jaeger-LeCoultre’s mastery of striking watches, built on a legacy of more than 200 different chiming calibres created over the course of 156 years and epitomising its commitment to tradition through constant innovation, the new iteration of the Duometre Grande Complication A Grande Sonnerie is a pièce unique (single-piece edition).

CALIBRE 101: A LANDMARK IN THE QUEST FOR MINIATURISATION

The art of miniaturisation: Since the early 16^th century, when clocks were first reduced to portable dimensions, the history of horology can be seen as a centuries-long quest for miniaturisation, as well as timekeeping precision. The fundamental challenge was to solve the conundrum that reducing the size of components almost invariably comes at the cost of robustness and reliability. From the mid-19^th century onwards, Jaeger-LeCoultre became known for developing very small movements – ensuring that mechanical quality did not need to be sacrificed for the sake of aesthetics and ornamentation. Among its innovations were the diminutive LeCoultre Calibre 7HP, introduced in 1880 for small enamelled and gem-set watches; and LeCoultre Calibre 6EB, introduced in 1908, which measured barely more than 1cm square.

The Duoplan breakthrough: By the 1920s, as wristwatches began to overtake pocket watches, a dramatic change in lifestyles had brought new demands, including a taste for smaller watches and more creative designs. LeCoultre’s solution was the Duoplan. Invented and patented in 1925, it was a rectangular movement with a two-level architecture (hence its name). By setting the escapement on one plane and the barrel and cogs on another, it effectively halved the amount of space required by the gear train of a conventional calibre. Equally ingenious, the mainspring is wound by a flat crown set into the caseback. The LeCoultre Manufacture went further and in 1929, introduced Calibre 101. Built on the Duoplan architecture, it represents the apotheosis of the quest to marry accurate timekeeping with tiny dimensions.

The world’s smallest rectangular calibre: At 14 mm long, 4.8mm wide and 3.4 mm thick (a volume of just 0.2 cm3), the 101 calibre comprised 74 parts and weighed barely one gram – the weight of two butterflies. Its balance wheel oscillates at 21,600 vibrations per hour (3 Hertz frequency) and the mainspring provides a power reserve of 33 hours. Created without the benefit of computer-aided design, laser cutting and CNC machining – all of which were at least half a century in the future – it was a remarkable feat. Underlining its unique value in watchmaking, it remains to this day the world’s smallest rectangular manually wound mechanical movement. It is also one of the world’s oldest movements to have remained in continuous production and has appeared in jewellery watches created by Jaeger-LeCoultre under its own name, as well as by other great Maisons.

A legacy in precision: Over the past nine decades, technology has enabled improvements in materials, gear-train design and production techniques but the calibre’s dimensions and architecture remain unchanged. Now with 98 parts – each of which must be custom-produced and adjusted due to their tiny size – the current version of Calibre 101 represents the fifth generation. Working in a specialised atelier dedicated to the calibre, only a handful of watchmakers have ever mastered the skills necessary to assemble movements at such a microscopic scale. Dexterity, extreme precision and great patience are required: it takes 40 hours to assemble the 98 components and production is, consequently, limited to only a few dozen pieces each year.

CALIBRE 101 SECRETS: A NEW HEIR TO A LONG LEGACY OF HIGH JEWELLERY WATCHES

Where jewellery meets time: The tradition of jewellery watches can be traced back to the Royal Courts of 18^th and 19^th-century Europe, when portable timepieces were potent symbols of privilege and wealth. In keeping with this status, the cases and dials were embellished by goldsmiths, lapidaries, enamellers, engravers and gem-setters. Thus, the arts of horology and jewellery – of technical ingenuity and aesthetic beauty – became inextricably linked. By the early 20^th century – decades after women had preceded men in wearing watches on the wrist – wristwatches were recognised as the most useful piece of jewellery that a woman could own.

A legacy of secret watches: Uniting superlative craftsmanship and micro-mechanical ingenuity with timeless design and beauty, the new 101 Secrets watch takes inspiration from the Maison’s long heritage in jewellery watches, including a series of fully diamond-set ‘secret’ watches from the mid-20^th century. Secret watches derived from the notion that ladies of the social elite did not need constant reference to the passing of time and, with a hinged cover over the dial that revealed the time only on demand, were not only the ultimate in discretion but also provided an ideal canvas for the jewellery arts.

Sapphires in perfect harmony: The new 101 Secrets watch adheres faithfully to the classical codes of High Jewellery: its double rivière-style bracelet is crafted in 18k Pink Gold (750/1000) and set with 124 pink sapphires (approximately 16.39 carats) graduated in both size and colour, from intense cyclamen to barely-there blush, encompassing 10 sizes and 7 shades. Separated by a contrasting band of grain-set white diamonds, the two rows of precious stones are claw-set to maximise the light that passes through them and thus amplify their colour and sparkle. The case sides are also grain-set with sapphires and diamonds – the latter extending the entire length of the bracelet. The time, when revealed, is displayed on a glowing white mother-of-pearl dial surrounded by a rectangular 18k Pink Gold (750/1000) bezel grain-set with diamonds, bringing the total to 904 brilliant-cut diamonds (approximately 13.26 carats). This tour de force of gem-setting, crafted in the Métiers Rares™ atelier in the heart of the Jaeger-LeCoultre Manufacture required 163 hours to complete.

Micromechanics, hidden in plain sight: In a marriage of micromechanics, technology and traditional craft, the development of the 101 Secrets watch required countless hours of research and many different areas of expertise to perfect the design of the case, the opening and closing mechanisms, the precisely articulated bracelet and the positioning of the gemstones. Designing the secret elements of the watch added to the challenge. The mechanism that reveals the dial had to be so tiny that it could be completely hidden within the rows of gemstones – its position known only to the wearer and activated by a hidden button at 6 o’clock. When the button is held down, a section of the bracelet pops open like the pages of a book, to reveal the time. Once the button is released, the dial disappears again into the ribbon of pink sapphires. A second tiny mechanism – also completely hidden – had to be developed for the clasp that fastens the bracelet to the wrist.

Showcasing Jaeger-LeCoultre’s exceptional expertise in both the technical demands of miniature watchmaking and the refined craft of gem-setting, the new 101 Secrets watch is a dazzling celebration of the creative freedom allowed by Calibre 101. The High Jewellery watch will be produced in a limited edition of three pieces.

We are delighted to welcome him to the Jaeger-LeCoultre family.”

This collaboration opens a new chapter for Jaeger-LeCoultre, deepening the Maison’s dialogue with contemporary culture through an artist whose singular vision, creative independence and quiet charisma reflect its core values. What unites both is not style, but a shared instinct for reinvention. Robert Pattinson will bring this connection to life through an upcoming campaign debuting mid-September.

Venice, La Serenissima. Renowned for its extraordinary light and beauty, the city has inspired generations of artists throughout the centuries. Among them was J.M.W. Turner, who found in Venice an inexhaustible source of inspiration. His luminous interpretations of the city not only captured its unique atmosphere but also helped shape the course of landscape painting in Western art.

This September, coinciding with its participation in the Homo Faber Biennale in Venice, Jaeger-LeCoultre pays tribute to the host city with four new limited-edition Reverso Tribute Enamel timepieces. The caseback of each watch features a miniature reproduction of one of J.M.W. Turner’s paintings of La Serenissima, reaffirming Reverso’s role as a canvas for artistic expression.

EXPRESSING A VISION OF ART AND CULTURE

Beginning in Europe and now extending worldwide, Homo Faber was created to honour and promote excellence in craft in all its forms. This aligns closely with Jaeger-LeCoultre’s commitment to supporting not only the highly specialised technical crafts inherent to watchmaking but also the artistic crafts associated with Haute Horlogerie. Expressing Jaeger-LeCoultre’s vision of art and culture, the new Reverso Tribute Enamel ‘Turner Series’ pays homage to this shared mission while showcasing the talents and skills of the Manufacture’s in-house Métiers Rares™ atelier.

Turner, a pioneer of modern art: Born in London in 1775, Joseph Mallord William Turner is acknowledged as one of the most influential painters in Western art history. While best known as a landscape painter, his work explored many aspects of the rapidly changing world in which he lived: industrialisation, profound social change and political and economic upheaval. Revealing a precocious talent from an early age, his first works followed the prevailing style of realism. However, rejecting established conventions, he soon developed a far more expressive approach, using loose brushstrokes – and sometimes his thumb or a palette knife – to create dynamic compositions. Employing colour and light not only to represent his subjects but also to evoke emotion, Turner transformed the course of landscape painting and anticipated artistic developments that would emerge many decades later. As a precursor of modern art, he exerted a profound influence on both Impressionism in the late 19^th century and Abstract Expressionism in the 20^th century. His artistic legacy has continued to shape generations of artists since his death in 1851.

Venice, Turner’s enduring fascination: Turner was intrigued by the very idea of Venice, his imagination fuelled by the writings of Shakespeare and Lord Byron. He made three journeys to the city – in 1819, 1833 and 1840 – the first when he was already a mature artist of 44. Each visit took place in late summer, when humidity shrouds the canals in a soft haze and the light seems to make the buildings levitate above the lagoon. Although Turner exhibited only 25 Venetian paintings during his lifetime, his output was remarkably prolific: over the course of his three visits, he produced some 150 watercolours and as many as 900 drawings in less than four weeks. His oil paintings of Venice were created later, upon his return to his London studio.

Capturing Turner’s light in enamel: The new Reverso Tribute Enamel timepieces unite the crafts of enamel miniature painting and paillonné enamelling on the casebacks with guillochage and enamel on the dials. The swivelling case of the Reverso lends itself naturally to artistic decoration and Jaeger-LeCoultre has used the blank metal reverse side of the case as a canvas on which its enamellers have created a series of highly accurate, miniaturised reproductions of celebrated works of art. To reproduce the shimmering beauty of Turner’s paintings, each Reverso Tribute Enamel timepiece requires approximately 80 hours of work.

As Turner’s works were of different formats, each view was cropped to capture the essence of the composition while also fitting the portrait orientation of the Reverso case. For each watch, the first of many challenges was to miniaturise the original works – the largest measuring 68 x 91 cm – to 2 cm^2, literally postage-stamp size, without losing any detail.

Equally important was capturing the ethereal quality of light and its shimmering effect on the water, as well as recreating Turner’s subtle interplay of perspective that characterises the original paintings. To achieve the ‘floating’ effect created by the clouds required the enameller to work across multiple enamel planes – a complex technique that began with the enameller to painting the clouds as part of the original miniature work, then applying (and firing) two layers of translucent enamel to those areas. The clouds are then repainted on top of these translucent layers before two more layers of translucent enamel are applied over the entire surface. To enhance the limpid effect of the light, the enameller used the craft of paillonage on areas depicting water, applying a sheet of silver leaf over the base enamel before beginning to paint the image with translucent coloured enamel.

To achieve the desired effects, each work required 14 layers of enamel – three base layers, four layers of painting and seven layers of translucent ‘fondant’ – with separate firings at 800°C after each layer. Discreetly positioned on each image, a secret signature in the form of a gold-leaf paillon identifies the enameller who created the piece.

The dialogue of guillochage and enamel: The colourful dials are decorated with meticulously hand-guilloché patterns beneath translucent Grand Feu enamel, with the patterns and colours chosen in response to the miniature paintings on the casebacks.

Capturing the light with every movement of the wrist, the intricate hand-guilloché patterns are engraved using a manually operated rose engine lathe, requiring up to 1,080 passages of the lathe. After completion of the guillochage, the enamelling requires an additional eight to nine hours of work for each dial, with up to five layers of enamel and six or seven separate firings at 800°C. The final challenge is the faultless application of the faceted indexes (requiring tiny holes to be drilled through the pristine enamel without cracking it) and the transfer of the chemin de fer minute track. The simplicity of the faceted applied hour-markers and Dauphine hands – design codes shared with every Reverso Tribute model – places full value on the beauty of the decoration.

THE LIGHT OF VENICE: FOUR EVOCATIVE WORKS RECREATED IN MINIATURE

While rich in detail, much of the art that Turner created in Venice was less about depicting the city itself than about exploring how the moods of nature – the light, the water and the sky – unfolded against the backdrop of Venice. Compelling and atmospheric, his paintings of La Serenissima capture the city’s fragility and fading glory as well as its grandeur, with a sense of melancholy behind its beauty. The artist evokes the transient effects of light, atmosphere and time with an almost cinematic quality, so that the viewer is not simply looking at an image but experiencing it with multiple senses.

Venice, the Dogana and San Giorgio Maggiore: Chosen as the setting for the Homo Faber Biennale, the island of San Giorgio Maggiore sits directly across the lagoon from St Mark’s Square. In Turner’s painting, made in 1834, the emphasis is on light, colour and reflection, with the bright white façade of the island’s eponymous church anchoring the composition and rows of buildings receding into the hazy distance. Silver paillons incorporated beneath the enamel enrich the texture of the lagoon, lending exceptional brilliance to the water and intensifying its constantly shifting reflections. The bustling activity of Venetian life – traders’ sailing boats, small vessels loaded with provisions and gondolas ferrying passengers across the canal – contrasts with the barely rippling surface of the lagoon. The green tones of the water are echoed on the dial, which is decorated with a new guilloché pattern, soleil croisé, creating a subtle texture beneath layers of richly lustrous enamel. This guilloché comprises 180 finely engraved lines, each executed in six successive passages of the rose-engine lathe, for a total of 1,080 passages.

Venice, from the Porch of Madonna della Salute: The hazy light brings a remarkable sense of depth to this view, with the foundations of the buildings seeming to merge into their reflections in the water and their architectural details sublimated by the atmospheric effect of light. Delicately applied silver paillons beneath the enamel heighten the texture of the water, capturing the subtle reflections and shimmering luminosity that define Turner’s vision of Venice. Painted in 1835, this work clearly demonstrates Turner’s evolving style, as he adapts watercolour techniques to oil painting – an innovation denounced by traditionalists that would nevertheless revolutionise the landscape genre. Based on a pencil sketch made by Turner during his first visit to Venice, the composition reflects studies developed further after his second visit in 1833. The green tone of the water is echoed in the Grand Feu enamel dial, where a rice-grain guilloché pattern creates constantly changing effects of light and shade as the wrist turns, echoing Turner’s rendering of Venice’s shimmering atmosphere. This vertical barleycorn guilloché is achieved through 70 precisely engraved lines, each requiring six successive passages of the rose-engine lathe, for a total of 420 operations.

Bridge of Sighs, Ducal Palace & Custom House, Venice: A direct tribute to the great 18^th-century Venetian artist Giovanni Antonio Canaletto, this is the first view of Venice that Turner painted in oils, completed 14 years after his initial visit to the city. Although not shown in this crop, the original painting depicts Canaletto seated at his easel in the far left of the composition. With reflections smudged by the hazy atmosphere of a late-summer day, the buildings appear to float between the lagoon and the sky, the rosy coral colour of the Doge’s Palace providing a counterpoint to the green of the water and the bright cerulean tone of the sky. The subtle reflections of the lagoon are further enhanced by delicate silver paillons beneath the enamel, adding remarkable texture to the water while amplifying its luminous interplay with light. The pure blue sky is echoed in the dial, where a basket-weave guilloché, composed of 46 finely engraved lines executed in six successive passages of the rose-engine lathe, is overlaid with translucent blue Grand Feu enamel, creating a shimmering effect as it catches the light.

Venice, the Bridge of Sighs. In this view of Venice, painted in 1840, Turner captures both the beauty and the decline of the city, contrasting the darker foreground with the glowing light reflected on the buildings. The effect is further enhanced by silver paillons beneath the enamel, which bring exceptional texture to the water while revealing ever-changing reflections as the light plays across the surface. Through the human figures, he expresses his concern for the profound social and economic changes of his time and, when he exhibited the painting, he accompanied it with two lines of a poem adapted from Byron, who had been deeply moved by the fall of the Venetian Republic: “I stood upon a bridge, a palace and a prison on each hand.” The subtle lavender tint in the blue sky is carried over to the Grand Feu enamel dial, where a wavy hand-guilloché pattern evokes the rippling reflections of light on Venice’s canals. This wide and deep horizontal wave guilloché is achieved through 41 precisely engraved lines, each requiring nine successive passes, for a total of 369 passages.

Calibre 822, a timeless movement: Like all time-only Reverso Tribute models, the watches of the Reverso Tribute Enamel ‘Turner Series’ are fitted with the manually wound Calibre 822, developed by Jaeger-LeCoultre specifically for the Reverso and a cornerstone of the collection for more than two decades. Shaped to fit the rectangular case, it measures just under 3 mm in height, ensuring the slender profile of the Reverso case and exceptional comfort on the wrist. With a power reserve of 42 hours and a frequency of 21,600 vibrations per hour (3 Hz), Calibre 822 delivers reliable precision, uniting fine watchmaking with the decorative crafts of guillochage, enamelling, paillonage and miniature painting.

Offered in a limited edition of 10 pieces per model, the Reverso Tribute Enamel ‘Turner Series’ is a tribute to the city hosting the Homo Faber Biennale.

Jaeger-LeCoultre is pleased to announce its return to Venice in September to participate in the fourth edition of Homo Faber Biennial, the world’s leading exhibition of contemporary craftsmanship. Created by the Michelangelo Foundation for Creativity and Craftsmanship, Homo Faber celebrates the savoir-faire of talented craftspeople from around the globe, honouring and supporting the priceless human skill behind the creation of beautifully handcrafted objects. This year’s edition of Homo Faber Biennial, designed around the theme An Island of Light by award-winning British stage designer and artist Es Devlin, will showcase the work of more than 500 highly skilled makers from over 70 countries, exhibited across 15 themed spaces. Homo Faber 2026 will take place at Fondazione Giorgio Cini on the island of San Giorgio Maggiore in Venice, from 1 to 30 September 2026.

A CELEBRATION OF BEAUTY AND A RARE INSIGHT INTO PRECIOUS CRAFT SKILLS

Underlining the exceptional savoir-faire of its Métiers Rares™ atelier and reflecting a core value of the Maison, Jaeger-LeCoultre has been chosen to participate in two of the themed spaces of Homo Faber 2026.

In “An Atelier Alive”, located in the Sala degli Arazzi, the Maison celebrates the talent and accumulated savoir-faire it continues to nurture in both watchmaking and the decorative arts through four new limited-edition Reverso timepieces. On the caseback of each watch, a minutely detailed reproduction of one of the early 19^th-century paintings of Venice by the great English artist J.M.W. Turner showcases the craft of miniature painting in Grand Feu enamel. Among them is ‘The Dogana and San Giorgio Maggiore’, depicting the very island on which Homo Faber Biennial takes place. Turner’s fascination with the Venetian light echoes the theme of Homo Faber 2026: An Island of Light. Alongside these miniature works of art, illustrating a shared commitment to beauty and heritage, visitors are invited to observe the delicate and demanding craft of Old Master painting restoration, as an expert restorer breathes new life into a Renaissance masterpiece.

Many of the motifs on Jaeger-LeCoultre’s Métiers Rares™ timepieces are inspired by nature, and the Sala Bianca, with its theme “An Infinite Birdsong”, provides the perfect setting for three more of the Maison’s creations. From the Vallée des Merveilles^TM series, two Reverso One timepieces showcase the crafts of gem-setting and enamelling with images of birds among blossoms, each requiring between 125 and 160 hours of gem-setting work. Alongside them, a new colour edition of the Atmos Régulateur Enamel ‘Colibris’ clock, the result of 230 hours of hand-enamelling, is framed by hand-painted Grand Feu enamel panels depicting hummingbirds among cherry blossoms and hydrangeas.

HOMO FABER FELLOWSHIP

Underlining its commitment, alongside the Michelangelo Foundation, to the preservation and transmission of vitally important craft skills for future generations, Jaeger-LeCoultre has been a founding partner of the Homo Faber Fellowship programme since its establishment in 2023. Redefining the traditional mentorship model, Homo Faber Fellowship offers an international, hands-on learning experience that combines the transmission of exceptional craft skills with business acumen, equipping emerging artisans to thrive in a sustainable craft economy.

Each year, the Fellowship brings together duos of renowned craft masters and emerging talents (fellows) for an eight-month sponsored training programme across Europe. Each cycle begins with a one-month residential masterclass combining creative workshops, design case studies and training in business skills and entrepreneurship. This is followed by a six-month residential placement for fellows in the studios of their respective masters, during which they exchange ideas, share skills and further develop their techniques through the co-creation of an object.

A selection of these objects has been curated for Homo Faber 2026, where they will be displayed across different exhibition areas, each reflecting the creative vision and craftsmanship it embodies.

INVENTIVENESS INSPIRED BY A UNIQUE ENVIRONMENT

The story of Jaeger-LeCoultre began in a hidden valley, high in the Swiss Jura, where Huguenot refugees settled in the 16^th century. To carve out a living from the beautiful yet harsh landscape, with its dense forests and bitterly cold winters demanded resilience and determination. Over generations, this resourcefulness was honed into ingenuity and inventiveness – a spirit that would eventually lead to the establishment of the LeCoultre watchmaking atelier in 1833. A constant stream of inventions was to follow – new production tools, the creation of the first integrated Manufacture, innovative manufacturing processes and unprecedented complications. This momentum, sustained to the present day, has been recognised by more than 430 patents.

Today, Jaeger-LeCoultre stands as a true Manufacture-Atelier, bringing together 82 ateliers, 108 crafts and 235 techniques – including 69 signature techniques – under one roof. It is a legacy shaped by place: a rarefied environment where landscape and climate forged the character of its people, whose ingenuity has, in turn, shaped the course of watchmaking history.

THE VALLEY OF INVENTIONS – A STORY OF PRECISION TOLD IN FOUR CHAPTERS

Visitors will be welcomed to The Valley of Inventions by a specially commissioned art installation that evokes the frozen landscape and forests of the Vallée de Joux in winter. A spectacular pine tree, sculpted from ice will form the centrepiece of an immersive show narrating the story of the place, the people and the inventions that shaped the Manufacture. Harnessing multi-sensory cinema technology, the show will feature synchronised physical and environmental effects that draw viewers deeply into the experience. Each of the four chapters in the story of Jaeger-LeCoultre’s mastery of precision will be devoted to a different facet of this crucial aspect of watchmaking.

Precision and Chronometry: Chronometry simply means timekeeping accuracy and the first chapter of the precision story explores the challenge of creating mechanical watch calibres that achieve the very high level of accuracy required to be certified as chronometers through a stringent testing process. In the 19^th century, LeCoultre & Cie produced chronometer-certified pocket watches for marine exploration, before developing precision instruments for aviation and for modern explorers and engineers with the Geophysic chronometer. The Master Control Chronometre collection, launched in April 2026, sets a new standard with double certification by both COSC and Jaeger-LeCoultre’s new HPG (High Precision Guarantee) seal.

Precision and Tourbillon focus on the regulating organ – the balance wheel and hairspring – whose isochronism is essential for accurate timekeeping. To counter the effects of gravity, Jaeger-LeCoultre developed its first tourbillon calibre, Calibre 170, in 1946. That same year, the calibre won the Neuchâtel Observatory chronometry competition with an exceptional variation of ±1 second per day. Since then, the Maison has refined tourbillon construction and hairspring design, with Calibre 978 winning the first modern chronometry competition in 2009 and inspiring the Master Grande Tradition Tourbillon Jumping Date unveiled at Watches and Wonders 2026.

Precision and Multi-Axis Tourbillons: Originally designed for pocket watches, the traditional tourbillon was not intended to fully compensate for gravity’s effects in wristwatch positions. In 2004, Jaeger-LeCoultre introduced the Gyrotourbillon 1, the Maison’s first multi-axis tourbillon, creating three-dimensional rotation to enhance chronometric precision and establishing its leadership in this field. Since then, each generation has pushed boundaries in engineering and miniaturisation, culminating in the 2026 Master Hybris Inventiva Gyrotourbillon à Stratosphère, featuring a triple-axis tourbillon architecture with three titanium cages rotating at different speeds to compensate for gravity in 98% of positions.

Precision and Complications: Adding complications – functions beyond hours, minutes and seconds – requires additional energy, which can affect precision by disturbing the stable power supply to the regulating organ. To overcome this challenge, Jaeger-LeCoultre created the Duometre system in 2007, with two independent barrels and gear trains separating timekeeping from complications to preserve isochronism. Building on 150 years of expertise in complicated calibres and minute repeaters, the Maison continues this pursuit in 2026 with a new expression of Calibre 362, advancing precision, acoustic performance and ultra-thin construction.

A CELEBRATION OF CRAFTSMANSHIP

Visitors will immerse themselves in the craft and art of watchmaking, with a focus on techniques central to the exhibition’s Métiers Rares™ theme.

La Vallée des Merveilles™: presenting a limited-edition capsule collection devoted to feminine timepieces. An ode to nature’s boundless beauty and diversity, La Vallée des Merveilles™ highlights the precision of the traditional decorative handcrafts such as enamelling, engraving and gem-setting practised in Jaeger-LeCoultre’s in-house Métiers Rares™ atelier.

New Reverso Tribute Enamel models: making their Asian debut, four unique creations, crafted through a rare, centuries-old artistry of color and fire, subtly capture the spirit of an iconic city. Each piece bears the intricate vision of a 19^th-century master.

Live Demonstrations: A rare opportunity to witness four high-watchmaking skills brought to life by Master Artisans from the Manufacture and engage directly with them as they share insights into their crafts. Hand-bevelling and enamelling reveal the precision and meticulous execution behind fine watchmaking, while a perlage demonstration highlights the artistry of decorative finishing. The programme concludes with a watchmaker from the Complications workshop assembling a Master Control Chronometre movement and explaining different tourbillon constructions – from traditional flat tourbillons to Jaeger-LeCoultre’s pioneering multi-axis Gyrotourbillon à Stratosphère.

A LABORATORY OF PRECISION

HPG Laboratory: a hands-on experience exploring the key stages of the stringent new High Precision Guarantee (HPG) seal, which certifies the accuracy and quality of the Maison’s watches. Visitors will immerse themselves in simulations of rigorous tests, including the shock test, the impact of changing pressures at different altitudes, various positions and variable temperatures. The High Precision Guarantee (HPG) seal guarantees not only the refined aesthetic finishes but also the high precision of the timepiece. This certification is met through a patented protocol that rigorously tests cased-up watches, replicating the daily wear of a watch.

Beyond precision, the laboratory experience also delves into the art of watch decoration, highlighting not only its aesthetic beauty but also its original functional purposes from historical watchmaking. This approach allows visitors to truly comprehend the profound intricacies of watchmaking.

The mystery of the Atmos and watchmaking objects: This display features a selection of key Atmos models, including the traditional Atmos Classic, an artistic interpretation of the Atmos Régulateur, as well as the Memovox Travel Clock by Marc Newson, which was newly launched during Milan Design Week.

A hands-on journey into Precision: for those wishing to deepen their understanding of watchmaking a Discovery Workshop focusing on the theme of Precision will be presented by the Atelier d’Antoine in a dedicated space within the exhibition. This dynamic and interactive workshop includes the rare opportunity for participants to try a key watchmaking skill, guided by an expert from Jaeger-LeCoultre. The Discovery Workshops are available upon invitation; participation is free of charge but reservations must be made in advance.

Jaeger-LeCoultre unveils two new Rendez-Vous models, highlighting the collection's versatility and distinct expressions of feminine elegance.

The Rendez-Vous Jewellery Night & Day, in a limited edition of just 10 pieces. Its multi-layered dial, miniature-painted in lacquer, is encircled by baguette-cut diamonds, all housed within a 34mm platinum case, offering an evocative new expression of the Night & Day complication.

In contrast, the Rendez-Vous Hour-Minute presents the collection's signature feminine elegance in a new, minimalistic style. It features a 29mm case in steel or 18K (750/1000) pink gold, a smooth polished bezel, an engraved caseback and a supple 'second skin' bracelet available in matching metal or polished alligator leather.

DEFINING MODERN FEMININITY

When introduced in 2012, at a time when very few mechanical watches were created exclusively for feminine wrists, the first Rendez-Vous was hailed as a groundbreaking timepiece, combining elegance and beauty with technical sophistication.

This approach has defined the Maison since its earliest years, when it created watches for women as well as men. Recognising the aesthetic and technical potential of timepieces that could also be worn as jewels, Jaeger-LeCoultre has continually responded to women’s evolving desires, reflected societal shifts and anticipated new trends. A contemporary expression of this philosophy, the Rendez-Vous collection embodies a modern and confident vision of femininity. Fourteen years after its debut, two new Rendez-Vous models demonstrate the art of subtle evolution, reinterpreting the collection’s original codes while remaining true to its spirit.

RENDEZ-VOUS JEWELLERY NIGHT & DAY

A rendez-vous between art and eternity: introducing a 34 mm platinum 950 case to the collection, the Rendez-Vous Jewellery Night & Day unites the technical and aesthetic sophistication of fine watchmaking with the richness of gem-setting and miniature hand-painting.

In a delightful ode to nature, the dial features an image of an Asian Paradise Flycatcher perched on a branch of Korean Dogwood blossom. Hand-painted in lacquer on a transparent sapphire dial, the composition brings to life one tiny brushstroke at a time, creating lifelike detail and a remarkable sense of visual depth. On a disc, set beneath the image of the bird, an ethereal rendition of the moon and sun is also hand-painted in lacquer. A new expression of the Night & Day complication, this disc completes one rotation every 24 hours, tracing the daily transition from sunlight to moonlight. This profound immersion masterfully crafts the perception of two distinct dials – one for day, one for night – each gracefully claiming a third of the total dial's expanse.

Defining the asymmetrical dial layout, the sinuous Floral numerals – a signature of the Rendez-Vous collection – are graduated in size to form a crescent that wraps around the upper section. Beneath the applied numerals, a fine oval-shaped ring draws the eye to the delicately painted image and Night & Day display. The captivating tableau is enhanced by diamonds, set into the platinum case by the specialist gem-setter in the Manufacture’s in-house Métiers Rares^TM atelier: the bezel lights up with a glittering circle of 48 baguette-cut diamonds; these are complemented by brilliant-cut diamonds on the case sides and lugs.

In keeping with the Rendez-Vous codes, an additional brilliant-cut diamond is reverse-set in the crown.

This poetic expression of femininity is brought to life by Jaeger-LeCoultre’s self-winding Calibre 733, whose finely decorated components are revealed through the transparent sapphire caseback. The automatic movement features a rotor, meticulously crafted from 22-carat gold (916/1000), a testament to horological excellence.

A blue alligator strap with a glowing ‘satin’ finish is matched to the blues of the dial and features Jaeger-LeCoultre’s proprietary interchangeability system, enabling the owner to change straps in an instant to create a different look if wished. The Rendez-Vous Jewellery Night & Day is unveiled as a truly exceptional offering, produced in a highly exclusive series of only 10 pieces.

RENDEZ-VOUS HOUR-MINUTE

Daily wear, redefined: with the introduction of the Rendez-Vous Hour-Minute, Jaeger-Lecoultre pares the Rendez-Vous aesthetic back to its essence, achieving a fine balance: minimalistic in spirit yet finely detailed; decorative without being elaborate; perfect for daily wear while dressy enough for evening. The 29 mm case, offered in either steel or 18K (750/1000) pink gold, features a convex bezel – polished, rather than diamond-set. The closed metal caseback is engraved with a stylised image of the sun.

Displaying hours and minutes only, the dials are designed as a series of concentric circles and feature the Rendez-Vous signature Floral numerals and sunray guilloché texture. On the outer edge of this, diamonds have a discreet presence as the hour markers, in keeping with the collection’s codes, while the inner edge is defined by a ring of deeply textured embossing.

The precious metal case of the 18K (750/1000) pink gold model is matched by the colour of the hands and numerals, which harmonise with the warm, creamy tone of the dial. The tone-on-tone palette is enhanced by an alligator strap in a soft taupe colour with a subtly glowing ‘satin’ finish. The strap also features the signature interchangeability system. Infused with a delicate jewellery essence, this timepiece is destined for daily wear, providing a discreet yet unwavering presence through every facet of life.

Metal bracelet, with a new aesthetic: The steel model, where blue hands contrast with the snow-white dial and cool tone of the case metal, is fitted with a new style of bracelet. Introduced exclusively for the Rendez-Vous collection in 2025.

Its modern lozenge-shaped links are designed for maximum flexibility, so that it drapes around the wrist as softly as a ribbon. The links are highly polished, with discreet areas of brushing to create visual depth and the bracelet is fitted with Jaeger-LeCoultre’s proprietary interchangeability mechanism to enable quick changes with a simple hand gesture.

More than simply marking the time, the new Rendez-Vous models offer two graceful and distinctly different interpretations of timekeeping for women. From the intricate detail and precious gem-setting of the Rendez-Vous Jewellery Night & Day to the relaxed, everyday elegance of the Rendez-Vous Hour-Minute, these new expressions of femininity are crafted to capture the imagination.

• Where artistic authenticity meets the art of fine watchmaking

• IU joins Jaeger-LeCoultre as Global Ambassador through The Hour Before

• A shared pursuit of excellence, creativity and timeless elegance

Jaeger-LeCoultre is delighted to announce internationally acclaimed artist and actress IU as its newest Global Ambassador. Revealed through the Maison’s interview series The Hour Before, the collaboration celebrates a shared spirit of artistry, authenticity and dedication to craft.

A JOURNEY SHAPED BY SINCERITY, DISCIPLINE AND CREATIVE EVOLUTION

Over the course of her career, IU has captivated audiences around the world through music, film and storytelling that transcend generations and cultures. Admired for her sincerity, artistic integrity and unwavering dedication to her craft, she has continually evolved while remaining true to her creative identity. From Korea’s beloved “little sister” to one of the most respected artists of her generation, IU has followed her own path with humility, discipline and quiet confidence.

With a strong parallel between her creative philosophy and that of Jaeger-LeCoultre, the relationship with the Maison comes very naturally. Like the Manufacture’s watchmakers, who devote countless hours to perfecting every detail, IU’s artistry is shaped by patience, precision and a constant pursuit of excellence. It is this shared spirit of dedication behind the scenes that makes her such a natural addition to the Jaeger-LeCoultre family.

A PRESENCE THAT REFLECTS QUIET ELEGANCE AND TIMELESS STRENGTH

IU’s presence is defined by authenticity, elegance and understated confidence. Her artistic evolution reflects a woman who has grown through experience and creative exploration while remaining deeply connected to who she is. Rather than following trends or relying on effect, her style is instinctive, refined and timeless.

Much like Jaeger-LeCoultre itself – creator of the iconic Reverso – IU embodies a modern elegance rooted in substance and simplicity. Within the Jaeger-LeCoultre Manufacture, every detail is refined with patience and intention, balancing technical mastery with timeless design. In the same way, IU’s artistry blends emotional depth with a natural sense of restraint, creating work that feels both contemporary and enduring.

In this sense, IU’s artistic evolution mirrors Jaeger-LeCoultre’s watchmaking philosophy through a shared pursuit of timelessness that remains profoundly in tune with the present. Both are guided by the belief that true excellence lies in depth rather than display, in the reinvention of classics rather than fleeting trends, and in creating lasting emotional resonance through authenticity, discipline and refined simplicity.

THE HOUR BEFORE: WHERE CRAFTSMANSHIP REVEALS PERSONALITY

Jaeger-LeCoultre introduces IU’s ambassadorship through The Hour Before, an intimate interview format built on a subtle and revealing contrast: as IU assembles the case of a Reverso, she gradually reveals herself. Guided by an off-camera interviewer, the conversation unfolds through elegant bridges between the Maison and IU’s personal world. Each question begins with Jaeger-LeCoultre before opening naturally onto her memories, values, tastes and perspective, creating an exchange that feels intimate, thoughtful and sincere.

The Hour Before offers a refined encounter where watchmaking becomes a gateway to personality. Through the precision of each gesture and the quiet rhythm of the conversation, the format reveals meaningful parallels between horological craftsmanship and artistic discipline: patience, dedication, attention to detail and the pursuit of excellence beyond the spotlight. Designed as a warm and natural conversation, The Hour Before captures a side of IU that is poised yet unguarded, offering a rare glimpse into the personality and quiet confidence behind her artistry.

“We are delighted to welcome IU to the Jaeger-LeCoultre family,” says Jérôme Lambert, CEO of Jaeger-LeCoultre. “Her authenticity, her dedication to her craft and her quiet elegance resonate deeply with the values of our Maison. Through The Hour Before, we are proud to celebrate the shared spirit of artistry, refinement and enduring excellence that defines both IU and Jaeger-LeCoultre.”

This collaboration marks an exciting new chapter for Jaeger-LeCoultre, further strengthening the Maison’s connection with individuals who embody authenticity, sophistication and a deep appreciation for craftsmanship and creative expression. IU will introduce this connection through The Hour Before and as part of the upcoming Reverso campaign.

• Nicolas Bonneville’s Made of Makers™ collaboration expands: introducing three exclusive olfactory creations for Jaeger-LeCoultre

• An encounter between haute perfumery and high watchmaking: composed with short formulas and high concentrations of noble ingredients, each fragrance leaves a lingering sillage

• Three distinctive olfactory signatures: The Adventure Spirit captures exploration in a woody-spicy composition; The Dream Shaper expresses femininity through a floral-leathery accord; The Sound Maker translates the mechanics of sound vibrations into a refined woody rose signature 

In 2026, the creative dialogue between Jaeger-LeCoultre and the Scent Artist Nicolas Bonneville enters a new chapter with the unveiling of three new olfactory signatures created exclusively for the Maison under its Made of Makers™ programme. Following the introduction of The Timeless Stories, The Celestial Odyssey and The Precision Pioneer in 2024, Nicolas Bonneville continues to explore Jaeger-LeCoultre’s sensory identity through three original creations: The Adventure Spirit, The Dream Shaper and The Sound Maker. Conceived as an extension of the Maison’s artistic universe, these new fragrances reaffirm the shared values that unite haute horology and haute perfumery ─ creativity, expertise and precision. Nicolas Bonneville, whose creative approach marries artistic intuition with technical expertise, conceived this new series as a lighter olfactory interpretation of the first collection. Complementing the initial three thematic fragrances, which expressed the Maison’s inspirations through richer and more intense compositions, these new creations offer a fresher and more luminous olfactory expression while remaining equally essential to the Maison’s DNA.

THREE NEW OLFACTORY SIGNATURES

The three new olfactory signatures crafted by Nicolas Bonneville embody the principles that distinguish haute perfumery from all other fragrances: short formulas, noble raw materials and high concentrations of key ingredients. Each composition reflects the same pursuit of precision that defines the Maison’s approach to watchmaking. Like the intricate mechanisms developed within the Vallée de Joux, these fragrances reveal their complexity gradually. Top, heart and base notes unfold with clarity and balance, allowing each ingredient to express its full character while contributing to a harmonious whole. The result is a refined and enduring sillage, leaving an evocative trail that captivates and lingers elegantly.

THE ADVENTURE SPIRIT is a woody-spicy fragrance in character. Inspired by Jaeger-LeCoultre’s legacy of precision instruments born from military needs, deep-sea expeditions and bold technical innovation ─ from the Memovox Polaris to the Master Compressor and Extreme Lab collections ─ The Adventure Spirit echoes the Maison’s exploration watches, created for those who pushed boundaries and set new records. Opening with an invigorating freshness from ginger extract, it unfolds into a warm, enveloping heart of sandalwood essence. As the scent settles, dry mineral nuances emerge, grounded by moss. Both energising and refined, the composition evokes the spirit of the contemporary adventurer ─ a man rooted in the city yet instinctively drawn to open horizons and untamed landscapes.

THE DREAM SHAPER is floral and leathery in character. Inspired by Jaeger-LeCoultre’s jewellery craftsmanship, technical miniaturisation and elegance ─ from the Duoplan and Calibre 101 to the Rendez-Vous collection ─ The Dream Shaper celebrates the Maison’s timepieces that redefined women’s watchmaking by uniting femininity with technical ingenuity. The fragrance begins with the freshness of bergamot essence before revealing a soft, powdery floral heart of mimosa absolute. Gradually, smoky, suede-like nuances unfold together with black tea extract, bringing depth and quiet sensuality to the scent. Balancing structure and softness, strength and grace, the composition reflects modern femininity ─ independent, confident and free to shape one’s destiny.

THE SOUND MAKER is a powerful woody-rose fragrance. Inspired by the mechanical artistry and acoustic heritage of Jaeger-LeCoultre ─ from the historic chapel of Le Sentier, built by Pierre LeCoultre to the Manufacture’s chiming complications ─ The Sound Maker transforms the vibrations of sound into an olfactory expression. From the first impression, mineral and smoky incense evokes the stillness of ancient stone and sacred spaces. At its heart, a rose-metal accord vibrates with unexpected intensity, creating a dialogue between warmth and brilliance. As the fragrance deepens, dry woods and musk notes leave a lasting, vibrant trail ─ like the lingering echo of a bell resonating through time.

Destined to become an additional signature of Jaeger-LeCoultre, the three fragrances crafted by Nicolas Bonneville will be offered as a special treatment to clients and will be used in a variety of other initiatives in the future.

• Celebrating the unseen moments that shape excellence

• Omar Sy joins Jaeger-LeCoultre as Friend of the House through The Hour Before

• A shared commitment to mastery, excellence and refinement

Jaeger-LeCoultre is pleased to announce Omar Sy as its new Friend of the House. Renowned for his magnetic screen presence, distinctive style and remarkable versatility across both French and international cinema, Omar Sy has established himself as one of the most influential figures of his generation. Admired for performances that combine strength with subtlety and humour with depth, he has built a career defined by a constant desire to evolve. These values resonate deeply with Jaeger-LeCoultre, where excellence is cultivated through the pursuit of mastery over time.

A long-time admirer of fine watchmaking, Omar Sy reflects: “For me, a watch is more than an accessory, it reflects a relationship with time, with discipline and with personal expression. I’ve always appreciated pieces that carry meaning through their design and craftsmanship. With Jaeger-LeCoultre, there is this quiet excellence and attention to detail that speaks without needing to be loud. That balance of tradition and innovation really resonates with who I am and how I approach my work.”

MASTERING A CRAFT, SHAPING A JOURNEY

For nearly three decades, Omar Sy has forged his own path. From his beginnings in comedy on radio and television to becoming one of the most recognised faces in international cinema, he has continually challenged expectations while remaining true to himself. Comedy may have been his first language, but it never defined the limits of his ambition. Refusing to be confined to a single genre, he has embraced complexity and continually expanded his creative horizons. Each role reflects a willingness to explore, to take risks and to evolve.

Like the watchmakers of Jaeger-LeCoultre, Omar Sy understands that mastery is built over time. Behind every accomplished performance lies an invisible process of preparation, discipline and refinement. Whether portraying vulnerability, resilience or strength, he brings a rare humanity to the screen, balancing gravity with warmth and confidence with humility.

A PRESENCE DEFINED BY SELF-ASSURANCE AND EASE

Omar Sy’s presence is marked by a rare balance of strength and warmth. Whether on screen, on stage or beyond the spotlight, he projects a quiet confidence that feels instinctive rather than cultivated. His style is never performative; it is grounded in authenticity and expressed with natural ease.

Throughout his career, he has remained open to new challenges while maintaining a strong sense of self. Effortlessly charismatic, he embodies a form of elegance that comes not from excess, but from sincerity and self-assurance.

This sensibility resonates naturally with Jaeger-LeCoultre’s philosophy. For the Maison, refinement lies in balance, precision and restraint. Like the Reverso, whose enduring appeal stems from the purity of its design, Omar Sy’s style is distinguished by its versatility and understated sophistication.

THE HOUR BEFORE: THE UNSEEN MOMENTS BEHIND SUCCESS

Jaeger-LeCoultre introduces its collaboration with Omar Sy through The Hour Before, a series dedicated to the often-unseen moments that precede defining achievements. More than a documentary format, The Hour Before invites reflection on what happens before success becomes visible. Before a breakthrough role. Before a standing ovation. Before a turning point. There is a quieter chapter marked by uncertainty, preparation and perseverance. The series explores these moments when choices are made, conviction is tested and ambitions take shape. Revealed in a sincere and personal light, the interviewees share experiences that transformed their journeys long before the world was watching.

For Omar Sy, those moments have been many: the decisions that challenged convention, the risks that opened new horizons and the determination that guided him from one chapter of his career to the next. His story embodies the spirit of The Hour Before: the belief that excellence is earned through countless unseen hours devoted to a craft.

“With his commitment to his craft, his quiet confidence and his distinctive and constantly evolving style, Omar Sy epitomises our Maison’s values and aesthetics,” says Jérôme Lambert, the CEO of Jaeger-LeCoultre. “Through The Hour Before, we are pleased to highlight this partnership, which feels very natural and we are delighted that he has chosen to represent us.”

• Refined dimensions: a new, slimmer 40 mm case with a reduced 12.9 mm profile, designed to fit a wider range of wrists

• Signature design codes: a dark blue gradient lacquer dial, bold hour markers and hands, and an inner rotating bezel for measuring elapsed time

• Manufacture precision: the automatic Calibre 899, offering high performance and a 70-hour power reserve

Deftly balancing contemporary elegance with a sporting spirit, Jaeger-LeCoultre reinterprets the Polaris Date in a more compact 40 mm case, enhancing wearability while retaining every element of its purposeful and dynamic design.

POLARIS: THE ELEGANCE OF JAEGER-LECOULTRE IN MODERN SPORTING STYLE

A sporting heritage born in the 1960s: In 1968, Jaeger-LeCoultre ushered in a new era with the launch of the Memovox Polaris, a watch distinguished by its unconventional large case, which established it as an icon of diving watch design. A bold statement of intent from the Maison’s watchmakers, it expressed a spirit of bold ambition that continues to define the Polaris collection today.

When Jaeger-LeCoultre revived the historic Polaris name in 2018, it reimagined the modern sporting watch through an entirely new collection of timepieces designed for a dynamic modern lifestyle. Deftly balancing the practical functions and robust capabilities of a sports watch with Jaeger-LeCoultre’s distinctively elegant and timeless aesthetic, the Polaris collection pays direct homage to the Maison’s eponymous diving watches of the late 1960s.

Powered by high-performance calibres and distinguished by instantly recognisable design codes, the Polaris timepieces embody the adventurous character of their predecessors while reinterpreting their vintage appeal through a distinctly contemporary lens. The result is a collection of versatile modern classics.

NEW COMPACT PROPORTIONS ENHANCE VERSATILITY

Precision in every detail: As tastes and lifestyles evolve, Jaeger-LeCoultre revisits the anchor model of the Polaris collection – the Polaris Date – introducing it in a more compact, 40 mm steel case. As well as reducing the diameter of the steel case, the Maison has slimmed it down to a thickness of 12.9 mm, preserving the ideal proportions of its bold and purposeful design while enhancing comfort, wearability and versatility. The Polaris Date is presented on a blue canvas strap, fitted with a double-folding buckle.

The Polaris collection’s distinctive aesthetic is anchored by its cases, which are distinguished by taut lines, glass-box crystals complemented by narrow bezels, a dynamic mix of brushed and polished surfaces, and dual crowns.

Positioned off-centre, the second crown adjusts the internal rotating bezel, enabling a countdown of pre-set elapsed time – a practical function derived from the diving watch ancestry of the Polaris collections. The steel case is water-resistant to 20 bar.

Performance inside and out: The sapphire crystal case-back reveals the finely finished automatic movement, Calibre 899. Exemplifying the pragmatic character of the Polaris collection, it combines mechanical elegance with high performance and offers a power reserve of 70 hours – highly practical for life on the move. Like the movement of every Jaeger-LeCoultre timepiece, it was designed, produced and assembled entirely under the Maison’s own roof.

A SIGNATURE DIAL

The dial of the new Polaris Date retains all the signatures that distinguish the collection.

A distinctive architecture based on concentric circles; assertively designed Arabic numerals and elongated trapezoid indexes; and skeletonised hands – with all indications coated in Super-LumiNova® for optimum legibility in low light conditions.

The lacquering of the dials is a lengthy and exacting process. After the grained and sunray finish are crafted, 7 layers of coloured lacquer and 35 layers of translucent lacquer are successively applied and finally meticulously polished by hand to create the mesmerizing double gradient dial with profound depth.

The new, more compact dimensions of Polaris Date elevate its confident modernity and relaxed elegance while underlining its sporty and purposeful character, anchoring it as a contemporary classic perfectly suited to life’s everyday adventures.

• The Collectibles: a programme of sought-after collection pieces offered for acquisition and presented at the London flagship from June 15 to July 18

• Watchmaking’s ‘golden age’: a curated selection of 7 rare Reverso pieces and 5 emblematic models from the beginning of the 20^th century to the early 2000s

• Museum-grade pieces: a meticulous care provided by the watchmakers of Jaeger-LeCoultre’s in-house restoration workshop at the Manufacture

Jaeger-LeCoultre is delighted to present the sixth capsule of The Collectibles, a meticulously vetted selection of 12 museum-grade timepieces to be unveiled in London on June 15 and available to collectors worldwide. The sixth capsule marks the first presentation of The Collectibles in London, an important hub for watch enthusiasts and collectors.

Its timing in June coincides with the Season, the period in spring and early summer when London traditionally hosts a rich programme of prestigious social, cultural, and sporting events, attracting visitors from all over the world. This capsule comprises a meticulously vetted selection of seven rare Reverso watches dating from 1931 to 2003. It is presented alongside five emblematic pieces from the golden age of watchmaking, in the mid-20^th century.

THE COLLECTIBLES PROGRAMME

The Collectibles is Jaeger-LeCoultre’s in-house programme dedicated to sourcing, restoring and offering rare, museum-grade timepieces from the golden age of watchmaking. Celebrating nearly 200 years of creativity, it highlights the Maison’s heritage through a curated selection of 17 emblematic models – from the Duoplan and Reverso to the Geophysic, Futurematic and Memovox Polaris – spanning the mid-1920s to the early 1970s. Presented through exclusive capsule releases worldwide, these timepieces invite collectors to become the next custodians of their stories. This commitment to heritage is made possible by Jaeger-LeCoultre’s dedicated restoration workshop, one of the very few maintained by a Manufacture. Here, ten master watchmakers meticulously restore each piece, servicing movements, hand-rebuilding components and sourcing historical parts from exceptional heritage stocks, while preserving original character and patina. Once restored and certified to museum standards, each timepiece is ready to continue the story it began in the Vallée de Joux.

REVERSO: THE EMBLEMATIC REVERSIBLE WATCH

The seven Reverso models offered in the sixth Collectibles capsule collection illustrate the depth and breadth of the Reverso’s evolution from its introduction in 1931 until the beginning of the early 21^st century. While Reverso was originally conceived for a sport – created to withstand the shocks of the polo field – it was quickly adopted by tastemakers from many walks of life, continuously evolving without compromising its identity to become recognised as an icon of Art Deco design. In the 1930s, LeCoultre & Cie distinguished itself with black dials, contrasting with the dominant silver and white dials in the watch industry. These black dials were hailed as 'the dial of the future' in the 1934 Spécialités Horlogères catalogue, which was the very first product catalogue from the association between Jaeger and LeCoultre. Reserved for only a select number of early Reverso references, these high-legibility dials reinforced the model’s resolutely modern character and are notably featured on three timepieces from this capsule: Reverso 1931, Reverso 1931 Dame and the Doctor’s Reverso.

The Reverso 1931 features this bold black dial with a railroad minute track and elongated trapezoidal indexes. It is fitted with the Tavannes Calibre 063, a pragmatic early solution while Jaeger-LeCoultre developed its own shaped movements from 1933 onwards. This Reverso is offered with a hand-crafted black calfskin leather strap.

Cased in steel and powered by the Tavannes Calibre 051, the Reverso 1931 Dame demonstrates how quickly the model evolved for different wearers. Adapting the same design language, its dial replaces the men’s minute track with bracket-like corner markers and refined Art Deco corners with trapezoidal indexes, details echoed today in the Reverso One collection. This Reverso is also offered with a hand-crafted black calfskin leather strap.

Set in a steel case, the 1938 Reverso Central Seconds, later nicknamed the Doctor’s Reverso, houses the Manufacture Calibre 411 and reflects the growing functional sophistication of the model. Designed with practicality in mind, its central seconds display features five-second intervals aligned with the elongated hour markers for optimal readability, making the precise measurement of pulse rates particularly easy. A highly practical tool for doctors of the time, it soon earned the enduring nickname “Doctor’s Reverso". This timepiece is offered with a hand-crafted black calfskin leather strap.

A two-tone Reverso from 1941 pairs steel with 18K yellow gold (750/1000), an innovative combination conceived to enhance durability while preserving the elegance of gold. Its 18K 18k yellow gold (750/1000) case bears the eagle head hallmark for French gold. Powered by the Manufacture Calibre 438, it features a small-seconds display at six o’clock, a configuration introduced in 1933 that became one of the defining signatures of early Reverso design. This timepiece is offered with a hand-crafted light-brown calfskin leather strap with cream-colored stitching.

A 1972 Reverso Corvo, produced in just 200 pieces, marks a pivotal chapter in the history of the Reverso. When changing tastes favoured functional watches, in a post-war era that prized practicality over elegance and amid the quartz crisis, Giorgio Corvo recognised the enduring appeal of the design. In 1972, he acquired the Maison’s final 200 unused Reverso cases and fitted them with the mechanical Calibre 840. Said to have sold out within a month to Italian clients, the Reverso Corvo proved that enthusiasm for the model had never faded and paved the way for its revival. Featuring a silver dial housed in a steel case, it remains powered by the manual-winding Calibre 840. This timepiece is offered with a hand-crafted black calfskin leather strap.

Set in an 18K white gold case (750/1000), a Reverso Sun Moon from 2000 reflects the renewed enthusiasm for mechanical watchmaking that emerged in the 1990s, when Jaeger-LeCoultre introduced a new generation of complication calibres for the Reverso, fitting them in cases with sapphire crystal backs to showcase the mechanical complexity. Equipped with the manual-winding Calibre 823, first developed in 1999, it pairs technical sophistication with an elegant display of celestial indications. Its black dial tracks the passage of the sun through a rotating 24-hour disc, coamplemented by a moon-phase display at six o’clock and a power reserve at eleven o’clock. Framed by a railway minute track and Arabic numerals, the composition balances clarity with refinement, while the sapphire crystal caseback reveals the movement with its recognisable pistol bridge. This timepiece is paired with a hand-crafted black Cordovan strap by the celebrated Argentinian polo bootmaker, Casa Fagliano.

A  Reverso Art Deco illustrates how the introduction of sapphire crystal casebacks encouraged a new expression of decorative craftsmanship within the collection: skeletonisation. First introduced in 1995, this 2003 example pairs an intricately hand-decorated, skeletonised interpretation of Calibre 822 with an elegant Art Deco aesthetic. Visible through the open caseback, the emblematic calibre is distinguished by blued screws and hand-engraved bridges adorned with a refined barleycorn motif. Its 18K white gold case (750/1000) frames a salmon-toned solid silver dial, where hand-guilloché patterns contrast with vertical brushing, complemented by dauphine hands and applied trapezoidal indexes. Archival records indicate that no more than ten pieces were made each month, reflecting the exceptional level of craftsmanship required for each timepiece. This timepiece is paired with a hand-crafted black Cordovan strap by the celebrated Argentinian polo bootmaker, Casa Fagliano.

The seven Reverso pieces are complemented by five watches that demonstrate the diversity of the 17 models included in The Collectibles programme. Each of the five additional watches offered in the sixth capsule represents a high-water mark for both Jaeger-LeCoultre and 20^th-century watchmaking, with groundbreaking innovations that exemplify the Maison’s pioneering spirit.

TRIPLE CALENDAR: THE GOLD STANDARD OF COMPLICATIONS

Jaeger-LeCoultre developed the first Triple (or Complete) Calendar calibre in 1942, a complication specifically designed for the growing wristwatch industry, displaying the date, day and month. An extremely elegant response to a concern for utility, intended for men of the world. As well as creating its own watches, Jaeger-LeCoultre supplied these calibres to some of the most renowned names in watchmaking. It thus became one of the most emblematic complications of the mid-20^th century.

Born in the early 1940s, the Triple Calendar by Jaeger-LeCoultre embodied a new generation of useful complications designed for everyday wear, combining timeless elegance with practical functionality.

Among the first complications conceived for a series-produced wristwatch, it left a lasting imprint on both the Manufacture and the history of watchmaking.

Dating from 1946, this rare Triple Calendar with Moonphase is housed in a 35 mm 18K yellow gold case (750/1000) produced in Paris by the Jaeger atelier and bearing the Edmond Jaeger hallmark. Made exclusively for the French market, it features a perfectly legible dial designed for exemplary ease of reading, in keeping with the spirit of military-inspired watches of the period. Powered by the manual-winding Calibre 494, the watch combines calendar indications with a moon-phase display integrated within the small seconds counter. It is fitted on a hand-crafted grained blue calfskin leather strap.  

THE DUOPLAN: A REVOLUTION ON THE WRIST

At the dawn of the partnership between Jaeger and LeCoultre, the Duoplan represented a genuine industry revolution. Built on two superimposed planes, the Duoplan calibre opened new creative possibilities for both companies. Invented in 1925, its rectangular two-level architecture enabled unprecedented miniaturisation by housing larger, more robust components within a compact construction. This breakthrough had a decisive impact on the design of women’s watches. It was also a revolution for LeCoultre & Cie, which, thanks to the Duoplan, transitioned from a movement and component producer to a full-fledged watch manufacturer.

An extreme miniaturisation with no concession to precision: the 1956 Duoplan Coulissante secret watch embodies Jaeger-LeCoultre’s technical ingenuity. Set on an 18K yellow gold bracelet (750/1000), its sliding element conceals the dial at will, revealing the secret character of the piece. The case and bracelet are finished with a wavy, textured pattern reminiscent of Clous de Paris decoration.

MEMOVOX: A SECOND MEMORY

In 1958, Jaeger-LeCoultre celebrated its 125th anniversary by launching three models that highlighted its expertise and the innovative character of its creations. Among them was a particularly striking interpretation of the legendary Memovox: the Memovox Parking. With a patented dial design highly recognisable thanks to its blue and white pictogramme, the Memovox Parking allows the wearer to set the alarm for a specific duration to avoid any parking ticket.

A 1958 Memovox Parking embodies a seemingly incompatible duality: elegance in 18K pink gold (750/1000) paired with purposeful functionality. Powered by the manual-winding Jaeger-LeCoultre Calibre 814, it transforms a refined dress watch into a discreet urban companion, thanks to its alarm function. The case bears the Edmond Jaeger hallmark (EJ), attesting to its Parisian craftsmanship in the Maison’s ateliers. It is fitted on a hand-crafted brown calfskin leather strap.

Produced in 1969, this steel Memovox Automatic Calendar, reference E855, pairs technical innovation with a strong visual identity. At the time, Jaeger-LeCoultre brought together two key advances in wristwatchmaking: the alarm complication and automatic winding. This 37 mm model features an elegant black dial with a date window at 3 o’clock and is powered by the self-winding Jaeger-LeCoultre Calibre 825.

Its distinctive character is further enhanced by its five-row bracelet made by Gay Frères and engraved with the company’s chamois hallmark. Fitted with its original Gay Frères steel bracelet, the combination with the black painted dial makes it one of the most sought-after Memovox Automatic models, crafted by the renowned Swiss specialist known for supplying the world’s most prestigious watchmakers. An additional hand-crafted black calfskin strap is also provided with the watch.

GEOMATIC: THE CHRONOMETER CALIBRE

Inspired by the legendary Geophysic, the Geomatic incorporates the best that the watchmakers from the Vallée de Joux could produce at the time. The Geomatic was developed as one of the most reliable automatic watch of its time. Highly precise and a true benchmark at its launch in 1961, it symbolises the ultimate combination of state-of-the-art technology and understated elegance thanks to its chronometer-certified movement and rich dial.

A rare Geomatic E560 from 1970, produced to just 200 pieces, is housed in an 18K yellow gold cushion-shaped case (750/1000).

Miami, May 20, 2026 - Swiss watchmaking Maison Jaeger-LeCoultre celebrated the opening of The Reverso Stories Pop-up in Miami Design District. Celebrating more than 90 years of the Reverso – an icon at the crossroads of watchmaking, architecture, and art – the exhibition invites visitors to discover the world of the Maison’s emblematic timepiece through a richly immersive Pop-up that is open to the public from May 21 to 31, 2026.

Hosted at Sweet Bird North (95 NE 40th St), this engaging experience marks a key moment for the Maison in the United States, ahead of the opening of its new boutique in the Miami Design District in Summer 2026.

CELEBRATING REVERSO

Last night, Jaeger-LeCoultre welcomed Kevin (NBA player) Love & Kate Love (model) to celebrate the opening of The Reverso Stories and the Art Deco origins of one of the world’s most recognizable watch designs. An exclusive and culturally driven moment celebrating horological craftsmanship through curated art, design and watchmaking in the heart of the Miami Design District.

THE LATEST CHAPTER OF AN ICON

From Art Deco to ‘Or Deco’: introducing three models each featuring 46 coloured gemstones and echoing classic cocktail timepieces: one in sapphire, one in emerald, and one in ruby; a new monochromatic version in 18K white gold (750/1000); and a smaller, unisex size for a more compact, versatile look. All novelties feature a Milanese bracelet and premiere in Miami, highlighting Reverso’s effortless ability to shift between sporty and elegant, contemporary and retro, masculine and feminine – often all at once.

From polo to Pegasus: on the Reverso Hybris Artistica Calibre 179 Pegasus, the 18K pink gold (750/1000) case is hand-engraved over 180 hours with the figure of Pegasus, where relief engraving and cloud motifs reveal the depth of Métiers Rares™ craftsmanship. The front dial combines layered architecture with hand-filled blue lacquer clouds, balancing decorative artistry and technical precision. On the reverse, the skeletonised Duoface movement exposes the Gyrotourbillon, enhanced by blue lacquer accents and contrasting finishes.

Beyond Reverso, Jaeger-LeCoultre continues to push the boundaries of precision with the Duometre concept. In 2024, Jaeger-LeCoultre introduced the Duometre Heliotourbillon Perpetual, uniting the Duometre concept with a multi-axis tourbillon in Calibre 388. It is now reinterpreted in platinum, featuring a new case and matching bracelet with a grey dial. This timepiece will be produced in a limited numbered edition of only 20 pieces and showcased exclusively during this Pop-up.

A RETROSPECTIVE JOURNEY AND A CREATIVE DIALOGUE

Presented in four chapters – Story of an Icon, Story of Design, Story of Innovation, and Story of Craftsmanship – the experience traces the Reverso’s evolution through emblematic models, from rarely seen archival timepieces to contemporary high jewellery creations, miniature-painted pieces, and highlights from current collections, including the Reverso Hybris Mechanica Calibre 185 with its four dials.

Further enriching this journey, a live demonstration of the decorative art of perlage offers a rare glimpse into a watchmaking technique rarely seen by the public.

Expanding the dialogue into other creative fields, Jaeger-LeCoultre’s Made of Makers™ programme – conceived to push the boundaries of classical arts through collaborations with artists, designers, and creators from diverse disciplines – brings together a series of artistic activations, each offering a unique interpretation of the Reverso:

-          Webcomic designer Olivecoat presents a fresh perspective on one of the Maison’s most iconic timepieces. In an archive-inspired webcomic that reinvents the ninth art, she retraces the story of Reverso through a contemporary lens, inviting visitors into an immersive narrative that highlights key moments in its history.     

             -          Digital media artist Dr. Yiyun Kang presents Origin, a bespoke large-scale 3D video sculpture commissioned by the Maison. Drawing on the subtle harmony of the Golden Ratio and the inherent complexity of Reverso, the artwork offers a poetic and contemporary interpretation of the timepiece’s design language.

             -          Acclaimed 2024 World’s Best Pastry Chef Nina Métayer enhances the experience at the 1931 Café with a culinary tribute that translates the harmony of the Golden Ratio into pastry form. For Miami, she introduces an exclusive signature creation, Splendeur Tropicale – a gourmet smoothie blending sun-ripened tropical fruits and refined textures, evoking both the city’s golden light and the harmonious proportions of the Reverso. This culinary experience is presented within a reimagined 1931 Café, offering guests a refined interlude where Swiss precision meets tropical light.

• New platinum 950 bracelet:  extending the timepiece’s refined monochrome aesthetic

• An innovative tourbillon: triple-axis construction creates a unique kinematic effect and enhances precision

• Calibre 388: allies the Duometre concept to a perpetual calendar with Grande Date display

• An exclusive production: each timepiece is part of a highly exclusive limited production of just 20 pieces

In 2024, Jaeger-LeCoultre created the Duometre Heliotourbillon Perpetual, uniting two lines of expertise in high-precision timekeeping – the Duometre concept and a novel form of multi-axis tourbillon – to create Calibre 388. Now, it reinterprets this highly sophisticated perpetual calendar timepiece in platinum, with a new case and matching bracelet complemented by a grey dial. It will be produced in a limited and numbered edition of 20 pieces.

A MONOCHROMATIC PALETTE CREATES AESTHETIC HARMONY

Crafted in platinum for this new model, the 44 mm Duometre case is a contemporary interpretation of the savonette pocket watches created by Jaeger-LeCoultre in the 19^th-century. Its rounded contours, amplified by the convex crystal, polished bezel and deeply notched winding crown are highly tactile as well as visually appealing. The apparent simplicity of the case belies its complexity: it comprises 40 separate parts and the lugs are screwed rather than integrated, to enable a mixture of polished, brushed and micro-blasted surfaces that play with shadows and reflections as every movement of the wrist captures the light differently.

Created specifically for this reinterpretation of the Duometre Heliotourbillon Perpetual, the new platinum 950 bracelet combines technical sophistication with refined elegance. Its supple five-row construction ensures exceptional comfort on the wrist, while alternating brushed and polished finishes echo the meticulous finishing of the case. Inspired by the vintage design codes of the Duometre collection, the bracelet’s fluid integration enhances the distinctive rounded silhouette of the case. Each link is individually domed along the 12 o’clock to 6 o’clock axis – subtly recalling the curvature of the lugs – and carefully brushed and bevelled on both sides to create a sophisticated interplay of light.

Harmonising with the cool silvery tones of the platinum case and bracelet, the new all-grey dial is finished in a mix of opaline, brushed and azuré surfaces, creating subtle contrasts between the different indications. The curving platinum bridge that separates the displays from the tourbillon aperture is finished with microblasting and bevelling. In contrast, the polished hands, applied hour markers and frames surrounding the date display create a subtle interplay of light.

Directly expressing the underlying Duometre mechanism, with its two barrels and gear trains, the symmetrical dial layout of the Duometre Heliotourbillon Perpetual forms a triangle, with its apex defined by the grande date display at 3 o’clock.  The two power reserves sit above and below the time display. The ‘base’ of the triangle is formed by the display of moon-phases and days in the upper sector, and the perpetual calendar’s months and years in the lower part.

On the left-hand side of the dial, the triple-axis tourbillon performs its ‘spinning top’ rotation and a sapphire crystal window in the side of the case offers another view of its mechanical dance. The tourbillon is set above a background of deep blue lacquer representing a starry sky and, as it spins, red triangles set on the third cage indicate 20-second intervals, which are marked on a sapphire crystal arc.

BREAKTHROUGHS IN PRECISION: THE HELIOTOURBILLON AND THE DUOMETRE CONCEPT

Incorporating Jaeger-LeCoultre’s eight decades of accumulated expertise in the tourbillon regulating mechanism, Calibre 388 features a distinctive tourbillon construction that spins on three axes, enhancing chronometry and creating a kinematic effect that resembles a spinning top.

As it spins on a single axis, the traditional tourbillon does not compensate for the effects of gravity in all positions, which led the Manufacture’s engineers to develop different configurations, including the signature dual-axis Gyrotourbillon. The Heliotourbillon takes this thinking further, with three titanium cages rotating on three axes and a cylindrical hairspring. The first cage is set at a 90-degree angle to the balance wheel and the second cage is set at 90 degrees to the first. Together, these two cages are driven and constrained by an axis tilted at 40 degrees which makes a full rotation in 30 seconds. The third cage is perpendicular to the second and makes a full rotation in 60 seconds.  Supported on ceramic ball bearings to minimise friction, the tourbillon consists of 163 components and weighs less than 0.7 grams. 

Before Jaeger-LeCoultre developed the Duometre concept, adding complications to a watch movement seemed irreconcilable with accurate timekeeping. That’s because the fundamental requirement of precise timekeeping is that the power supply from the barrel to the escapement should never vary. However, a complication must draw on the power supply to operate, thus interrupting that steady flow and jeopardising precision. Introduced in 2007, the patented Duometre mechanism features two barrels and two separate gear trains housed in a single calibre and linked to a single regulating organ. One gear train powers the time indications and the other drives all additional functions. By separating the power supply in this way, the Duometre mechanism guarantees an exceptionally high degree of operating accuracy.

A PERPETUAL CALENDAR WITH A GRANDE DATE DISPLAY

Complementing the sophistication of the tourbillon and Duometre mechanisms, Jaeger-LeCoultre’s watchmakers integrated a perpetual calendar into Calibre 388. Automatically adjusting for months of different lengths and for leap years, it needs no manual correction until 2100 and subsequently only in centenary years that are not also leap years. The year indication shows the last digit of a leap year in red – a Jaeger-LeCoultre patent. Unusually, in Calibre 388 the hours and minutes can be set either backwards or forwards without compromising the perpetual calendar. Normally, a perpetual calendar is set through the passing of time (the hour and minute hands), so adjusting the time backwards desynchronises and can damage the calendar mechanism. Calibre 388 also includes a Grande Date display: a classical yet rare complication sought-after by watch connoisseurs, and a moon-phase indication accurate to 122 years.

Calibre 388 features fine decoration, even on components that are not visible through the sapphire crystal caseback: brushed surfaces contrast with perlage; edges are hand-bevelled and polished; sunrayed Geneva stripes (côtes de Genève soleillées) radiate seamlessly across the expanse of the bridges. Like all Jaeger-LeCoultre movements, Calibre 388 was conceived, designed, produced, assembled and finished within the Manufacture.

Complex, highly innovative and aesthetically refined, the Duometre Heliotourbillon Perpetual in platinum epitomises Jaeger-LeCoultre’s boundless creativity and its technical sophistication represents a new achievement in the Maison’s quest for timekeeping precision.

As it continues to expand the mechanical and artistic potential of Haute Horlogerie through the Hybris series of limited-edition timepieces, Jaeger-LeCoultre revisits the Reverso Hybris Artistica Calibre 179, harnessing the skills of the master engravers in the Manufacture’s Métiers Rares^TM atelier.

Presented in an 18K pink gold (750/1000) case richly engraved with an image of Pegasus, the flying horse of Greek mythology, the new timepiece also features hand-lacquered dial plates and bridges. The fully skeletonised reverse dial is complemented by hand-bevelling of the bridges and tourbillon cage.

Reverso Hybris Artistica Calibre 179 Pegasus is presented on a blue alligator strap with an innovative, micro-adjustable clasp and will be a limited edition of five pieces.

SHOWCASING THE ARTISTRY OF THE MÉTIERS RARES^TM ATELIER

From polo to Pegasus: The legendary winged horse of Greek mythology – believed to have carried thunderbolts for Zeus and to have created springs to flow wherever its hoof touched the ground – Pegasus symbolises freedom, creative power and elevation beyond limits. More than a myth, it represents the moment when technique becomes imagination.

This symbolism resonates with the Reverso’s equestrian origins. Designed on the polo field, its swivelling case reflects a constant interplay between protection and expression, discipline and freedom – echoing the dual nature of the horse itself. The connection extends through the Year of the Fire Horse, a sign of intensity, independence and bold energy. Together, these references position the horse as more than inspiration: a thread that unites function, symbolism and creative transformation at the heart of the Reverso.

Celebrating the savoir-faire of Jaeger-LeCoultre’s Métiers Rares^TM atelier, the hand-engraved case marries rare artistic sensibility with remarkable precision and dexterity: the Maison’s master engraver must devote 180 hours of intensely focused work to each watch, to craft the image of Pegasus against a background of clouds. The sculptural effect of the relief engraving creates areas of reflection and shadow, emphasising the sense of volume. As the engraving wraps seamlessly around the convex case-sides, it almost completely obscures the join between the upper and lower sections of the case.

Where mechanism becomes art: The cloud motif that forms the backdrop to Pegasus is repeated on the front dial, where two dial plates – each on a different level – enhance the symmetry of the time display and the tourbillon aperture.

To create the decoration, more than 50 hollows were formed in the surface of the 18K pink gold (750/1000) plates, leaving only the cloud-shaped outlines visible. Each hollow is then hand-filled with different shades of blue lacquer, applied in multiple layers until its surface is perfectly flush with the outlines.

Between the plates, open-worked bridges, also hand-lacquered in dark blue, offer a tantalising glimpse of the movement – in keeping with the Hybris philosophy of celebrating mechanical as well as decorative art.

Turning the case over to the reverse dial, where the Duoface movement displays the second time zone, the beauty of the calibre is fully revealed.

Blue lacquer has been applied to the fine tracery of the skeletonised hours-minutes ring and its supporting bridges, highlighting the airy aesthetic. It contrasts with the warm tones of the 18K pink gold (750/1000) movement components and the soft texture of micro-blasted surfaces.

The skeletonisation is complemented by hand bevelling and hand-applied lacquer. Representing approximately 14 hours of hand-bevelling work only for the cage of the Gyrotourbillon and eight hours for the signature shape of one bridge on the reverse side, the Reverso Hybris Artistica Calibre 179 is testament to Jaeger-LeCoultre’s commitment to craftsmanship of the highest order.

A MECHANICAL MASTERPIECE

Inspired by a fascination with the tourbillon: Calibre 179 features the fourth evolution of the Gyrotourbillon, Jaeger-LeCoultre’s signature multi-axis tourbillon – a technical tour-de-force developed expressly for the rectangular case of Reverso. The demand that the regulating mechanism be integrated into a shaped movement that follows the contours of the rectangular Reverso case and is slim enough to be comfortable on the wrist, makes the engineering feat even more noteworthy. Moreover, as a Duoface movement, Calibre 179 displays a different time zone on each dial as well as a 24-hour indicator on the reverse dial.

Highly complex and visually enthralling to observe as it pirouettes around its twin axes, the Gyrotourbillon comprises 123 components, including one ultra-light titanium cage and a peripheral carriage mounted on ball-bearings. These two elements turn perpendicularly to each other at different speeds – the inner tourbillon cage rotating 360 degrees in just 16 seconds and the peripheral carriage making a full rotation once per minute. This peripheral carriage also provides a small-seconds function, indicated on a ring that encircles the tourbillon aperture. A closer look reveals a greyed semi-spherical balance spring beating at the heart of the mechanism, as well as the distinctive double-anchor shape of a Gyrolab balance ‘wheel’ – both elements paying testament to Jaeger- LeCoultre’s tireless quest for greater precision and mechanical efficiency. In this quest, the Manufacture’s engineers have created balance springs in several different forms over the years and this hemispherical shape, perfectly adapted to the hollow sphere at the heart of the Gyrotourbillon, adds aesthetic refinement as well as mechanical efficiency. The double-anchor shape of the Gyrolab was designed to reduce air friction and thus further enhance timekeeping accuracy.

Rather than being held in place by a conventional bridge, the tourbillon mechanism is supported by a ring of ball bearings, creating the illusion that this flying Gyrotourbillon is floating freely in the space between the front and back dials of the Reverso. The effect is amplified by the light reflected from the mirror-like surface of a polished blue lacquer disc positioned on the supporting cradle of the watch directly beneath the tourbillon aperture.

REVERSO: FROM ART DECO ORIGINS TO TIMELESS DESIGN ICON

Since its creation in 1931, the Art Deco lines and swivelling case of the Reverso have made it one of the most recognisable designs in watchmaking.  The rectilinear geometry and harmonious proportions of the case belie the complexity of the signature slide-and-swivel mechanism. Emphasised by the signature gadroons above and below the dial and a deeply engraved sunray pattern on the inside of the case cradle, the strong Art Deco lines counterbalance the intricate decoration of the case and dials of the Reverso Hybris Artistica Calibre 179 Pegasus.

A movement as complex as Calibre 179 naturally requires a generously sized case; however, with a thickness of 12.41mm and refined lugs, Reverso Hybris Artistica Calibre 179 Pegasus is both elegant and wearable. Fastening the dark blue alligator strap, the adjustable folding clasp epitomises Jaeger-LeCoultre’s approach to refined elegance through technical innovation. Crafted in 18K pink gold (750/1000) and comprising 46 components, it incorporates an intricate double-wheel system that allows for micro-adjustments to the nearest 0.5mm, ensuring a perfect fit.

Crafted for true connoisseurs of art and mechanics, the Reverso Hybris Artistica Calibre 179 Pegasus blends exceptional watchmaking savoir-faire and decorative artistry in a noble expression of the 180 skills brought together under one roof at the Manufacture Jaeger-LeCoultre.

• New expressions of an icon, introducing: three models each featuring 46 coloured gemstones and echoing classic cocktail timepieces, a new monochromatic version in 18K white gold (750/1000); and a smaller, unisex size for a more compact, versatile look

• Vintage elegance: pairing a Milanese bracelet – requiring more than 10 metres of 18K pink gold (750/1000) or white gold (750/1000) – with a matte-grained dial, strikingly contrasted by the luminous shine of its applied indexes and Dauphine hands, unveiling a refined reinterpretation

• Iconic swivelling case: comprising 50 components and measuring 7.56 mm thick, its Monoface design offers endless possibilities for personalisation with its distinctive Art Deco 

Following the resounding success of the Reverso Tribute Monoface Small Seconds ‘Or Deco’ in 18K pink gold (750/1000) in 2025, Jaeger-LeCoultre expands this distinctive expression of the Reverso with the introduction of five new models:

-          The Reverso Tribute Monoface Small Seconds ‘Or Deco Cocktail’: a trio of gem-set variations, in 18K pink gold (750/1000) with rubies, or 18K white gold (750/1000) set with either emeralds or blue sapphires

-          The Reverso Tribute Monoface Small Seconds ‘Or Deco’: available in 18K white gold (750/1000)

-          The Reverso Tribute Monoface ‘Or Deco Solo Tempo’ in 18K pink gold (750/1000), resized and a return to the essence of time

FIVE ‘OR DECO’ NOVELTIES

Recalling the golden age of gem-set cocktail watches born from the Art Deco movement, first seen in the 1920s and truly coming into their own during the 1930s, the Reverso Tribute Monoface Small Seconds ‘Or Deco Cocktail’ is presented in three versions: in 18K pink gold (750/1000) with rubies and 18K white gold (750/1000) with either emeralds or blue sapphires – each model is an edition limited to 30 pieces.

The baguette-cut stones for each timepiece, set between the gadroons above and below the dial, amplify the Reverso’s rectilinear geometry and create a vivid contrast with the polished gold case and Milanese bracelet, complemented by the subtle texture and matte effect of the grained dial.

The baguette-cut stones, set between the gadroons above and below the dial, heighten the Reverso’s signature rectilinear geometry while reinforcing its vintage character. The gem-setters of Jaeger-LeCoultre’s Métiers Rares™ atelier use rail setting – an ‘invisible setting’ technique perfected in the 1930s – to create an unbroken line of colour and light. Requiring extreme precision to achieve loupe-perfect straight edges and to lock the stones securely in place while ensuring that their surfaces are exactly level with each other, rail setting involves forming a framework of tracks (rails) a fraction of a millimetre wide in the gold beneath what will be the level of the stone. The gem-setter then slides the stone onto the track and folds a minute amount of gold over its edge to secure it before sliding the next stone into place. Through the rail setting technique, the gem-setter’s challenge lies in delicately folding the gold of the case over the 46 baguette-cut blue sapphires without compromising the stones. Each stone is set edge-to-edge and secured thanks to the rail and the case’s gold, creating a continuous flow of light with no other points of support. Each gem-setting technique demanded meticulous work; however, due to its inherently fragile attributes, the emerald was the stone that required the most specialised attention. Its delicate nature necessitated extreme precision in handling and setting, ensuring every facet of its vibrant beauty was preserved and perfectly showcased without risk of damage.

Set in a case measuring 45.6 mm x 27.4 mm with a slim profile of 7.56 mm, the Reverso Tribute Monoface Small Seconds ‘Or Deco Cocktail’ novelties are powered by the same hand-wound Calibre 822 as featured in the 2025 original Reverso Tribute Monoface Small Seconds ‘Or Deco’, a movement that still features a small seconds display at 6 o’clock on the dial and provides a power reserve of 42 hours. The same movement, which is shaped to echo the lines of the rectangular case, was also designed, produced, and assembled entirely in-house.

Completing the new ‘Or Deco’ series for 2026, the Reverso Tribute Monoface Small Seconds ‘Or Deco’ is now presented in 18K white gold (750/1000), as well as the original 18K pink gold (750/1000). The cool, monochromatic effect is enhanced by the subtle visual shift from the soft and powdery texture of the grained silvery-grey dial to the high shine of the polished 18K white gold (750/1000) Milanese bracelet and matching case. Set in a case measuring 45.6 mm x 27.4 mm with a slim profile of 7.56 mm, the Reverso Tribute Monoface Small Seconds ‘Or Deco’ in 18K white gold (750/1000) is fitted with the hand-wound Calibre 822, which offers a power reserve of 42 hours.

In the spirit of ‘less is more’, the uncluttered details and essential dimensions of the Reverso Tribute Monoface ‘Or Deco Solo Tempo’ make a bold statement of style. Dispensing with the small seconds display refines the dial to its essence, while the smaller case takes this new Reverso closer than ever to the dimensions of the 1930s originals (39 x 21 mm).

With its monochromatic pink gold aesthetic, free of ornamentation and measuring 40.1 mm x 24.4 mm, it is a perfect fit both physically and stylistically for wrists of all sizes, male and female alike. The slender, 7.56 mm case is fitted with Jaeger-LeCoultre’s manually wound Calibre 822, which ensures a power reserve of 42 hours.

As Jaeger-LeCoultre continues to explore and expand the creative universe of the Reverso, the addition of the ‘Or Deco’ series to the Reverso Tribute collection underlines the timeless beauty and great versatility of its Art Deco design. Blending vintage glamour and confident modernity, the new watches are destined to become contemporary classics.

THE CONSTANTLY EVOLVING STYLE OF A DESIGN ICON

Reverso, an icon: Created in 1931, the Reverso was designed to meet the demands of the newly fashionable ‘sporting gentleman’. A challenge was set by polo-playing military officers in India during the British Raj of 1858-1947 to create a watch that could withstand the rigours of the polo field.

Reverso was the answer – a masterful integration of form and function. Quickly adopted by tastemakers from all walks of life, the Reverso soon transcended its original sporting purpose as new variations appeared – for both men and women. However, its iconic double-sided case and distinctive Art Deco lines have remained constant, making the Reverso one of the world’s most recognisable wristwatches. Over the decades, many variations of the Reverso have been created, both stylistic and mechanical, without ever compromising its identity. The distinctive and timeless design accounts for much of the Reverso’s enduring appeal – and for its recognition as an icon of Art Deco style.

Milanese mesh, a story behind the style: With a flat and silky-smooth finish, Milanese mesh is made by twisting fine threads of metal together in a particular way to form a double layer of densely interlocking small links. Because it requires no pins to join any sections, it is as flexible as a ribbon and highly durable. Milanese mesh originated in 13th-century Milan (from which it takes its name) as a type of chain mail armour. Renaissance goldsmiths then developed precious metal versions of the mesh for jewellery. However, the craft remained almost unknown outside Italy until the 1920s, when German jewellers mastered the technique.

Over the past century, the story of Milanese mesh has surprising parallels with that of the Reverso: as the epitome of Art Deco style, both became the height of fashion in the 1930s. Then, in the mid-20^th century, as tastes and lifestyles changed, their popularity waned – before both enjoyed great revivals in the 1970s. Milanese mesh was ‘reborn’ for watch bracelets perfectly in tune with the ’70s aesthetic and the Reverso was rediscovered by the Milan-based watch distributor Giorgio Corvo, prompting a full relaunch by Jaeger-LeCoultre. Coinciding with the revival of mechanical watchmaking after the ‘quartz crisis’, the Reverso’s star ascended rapidly. Meanwhile, Milanese mesh again fell out of fashion until recently, when its crossover style – vintage-modern, sporty-elegant, masculine-feminine – sparked the latest revival.

Rather than simply adding a Milanese mesh bracelet to an existing design, each watch in the ‘Or Deco’ series was conceived and designed as a cohesive whole, with a unified all-gold aesthetic achieved through a mix of shades and textures. The finely grained dial provides a subtle counterpoint to the polished shine of the case, bracelet and applied hour indexes. The brushed finish of the 18K gold (750/1000) integrated buckle provides further contrast with the shiny polished Milanese mesh. 

The slim profile of the Milanese bracelets was carefully studied to best complement the slender form of the 7.56 mm-thick Reverso case: the thickness of the gold thread – and consequently, the size of each mesh link – were crucial to attaining the most harmonious balance. To achieve a visually seamless case-to-bracelet integration, a specialised attachment link was developed: the barrette passes directly through the links, rather than using a traditional tube structure, and the lug holes were redesigned to accommodate it. The integrated sliding buckle was also designed from scratch. On the wrist, the bracelet feels as smooth, soft and sinuous as a second skin – fitting perfectly thanks to the infinitely adjustable sliding clasp, and beautifully balanced thanks to the weight of the gold.

The five novelties, unveiled in the sillage of the Reverso Tribute Monoface Small Seconds ‘Or Deco’ with Milanese link bracelet, perfectly highlight the Reverso’s unique adaptability to evolve over time – balancing contrasting qualities: sporty or elegant, contemporary or retro; masculine or feminine, and often a blend of several attributes at once.

• Reverso: since 1931, continuously reinvented, never compromising its identity

• Design codes: reduced proportions, truer to the original, for a refined fit on slimmer wrists
• Performance and precision: signature calibres 846 and 844 are reimagined with a total of 16 enhancements to the mechanisms

For much of the 20th century, wristwatch design was shaped by a cultural preference for restraint. Above all, watches were instruments of precision and markers of refinement, designed to sit discreetly on the wrist. Men’s watches typically measured between 30 and 34 mm, reflecting ideals of elegance and proportion, while women’s timepieces were often conceived as intimate, jewellery-like creations, sometimes even smaller. The Reverso, created in 1931, embodies this philosophy. Its rectangular case, born from a functional brief, naturally lent itself to compact dimensions, becoming a canvas for both masculine sophistication and feminine expression. Over time, evolving lifestyles and aesthetics led to a gradual increase in watch sizes, favouring a stronger presence on the wrist. Today, however, a renewed sensitivity to comfort, authenticity and timeless design is bringing smaller proportions back into focus, reconnecting with a more classical vision of watchmaking. As a tribute to this heritage, Jaeger-LeCoultre revisits some of the most emblematic Reverso models through a selection of smaller, more refined interpretations.

-          Reverso Classic Small Monoface: 2 versions are available – one in steel with an alligator strap or steel bracelet, and one in 18k pink gold (750/1000) with an alligator strap.

-          Reverso Classic Small Duetto: 3 versions are available – two in steel, one set with diamonds on the verso, with an alligator strap or steel bracelet with an additional alligator strap and one set with diamonds on both sides, with a blue alligator strap or steel bracelet, offered with an additional alligator strap. The last version is offered in 18k pink gold (750/1000), set with diamonds on the verso, available with an alligator strap or 18k pink gold (750/1000) bracelet with an additional alligator strap.

-          Reverso Classic Monoface ‘Origin’: With their gadroons set with diamonds on the recto, presented in steel with an interchangeable blue alligator strap or with a steel bracelet.

-          Reverso Tribute Duoface Small Seconds: Crafted in steel, featuring an interchangeable strap in black calfskin and grey canvas with a double-folding buckle.

SIGNATURE DESIGN CODES, SUBTLY REFINED

Immediately recognised by their swivelling case and Art Deco lines, both Small models are presented in steel or 18K pink gold (750/1000). On the front dials, the Reverso Small models’ timeless signatures are maintained: a guilloché sunray pattern in the central rectangle appears to extend seamlessly into the markings on the chemin de fer minutes track. The textured pattern and vertically brushed dial forms the backdrop to the crisply defined Arabic numerals.

The Reverso Classic Small Monoface is complemented by alligator straps: the 18k pink gold (750/1000) version comes with taupe alligator and the one in steel with blue alligator strap or the option of a polished five-row steel bracelet. Adding a subtle touch of refinement, the ‘JL’ logo on the dial is now applied rather than transfer printed.

As with all Monoface models, the blank metal caseback invites personalisation with engraving or lacquer work, to celebrate a treasured memory or express individual style – an element that the owner can keep private or display to the world, according to which way the case is turned.

Offered in steel or 18k pink gold (750/1000), the Reverso Classic Small Duetto features a subtly modernised dial with new tone-on-tone applied numerals and ‘JL’ logo creating a harmonious and nuanced three-dimensional effect. The reverse dial also gains a sleeker and more contemporary look: the absence of numerals for 12 and 6 amplifies the sunrayed effect of the circular centre, while applied ‘double sunray’ indexes reinforce the pattern of the guilloché outer section. Underlining the Maison’s commitment to craftsmanship, more than 20 steps are required to create the two dials. While the Reverso Duetto traditionally features diamond-set gadroons on the reverse side of the case only, a new ‘Double Set’ option in steel is set with brilliant-cut diamonds on both sides of the case.

The Reverso Classic Small Duetto is offered with a strap package comprising a blue alligator strap and a steel bracelet (steel case) and a taupe alligator strap and 18k pink gold bracelet (pink gold case). All models feature Jaeger-LeCoultre’s signature interchangeability system, enabling an effortless and rapid change of style with fingertip operation.

Introduced in 2025, the Reverso Classic Monoface ‘Origin’ pays homage to the proportions and aesthetics of the first feminine Reverso, created in 1931. A new interpretation features diamond-set gadroons, enhancing the play of light on the dial finishes and case. Presented in a steel case, with the option of a blue alligator strap or polished steel bracelet, it features the unique attribute of all Monoface models: a blank metal caseback that can be personalised with engraving or lacquer. It can be worn in two ways: with the decoration hidden and the dial showing or with the case flipped over and worn like a piece of jewellery, with the time hidden until the wearer wishes to see it.

For 2026, the Reverso Tribute Duoface Small Seconds has been reinterpreted with smaller case dimensions of 42.9 mm x 25.5 mm, creating a new ‘medium’ size that is closer to the original Duoface models of 1994. With this return to a classical size, the silvered-coloured opaline front dial is complemented by a blue-grey reverse dial that displays the second time zone – a colour new to the Duoface line that is enhanced by sunray satin-brushing and the polished steel of the case. Fitted with the manually wound Calibre 854, the Reverso Tribute Duoface Small Seconds is presented with a black calfskin, designed by Casa Fagliano, featuring Jaeger-LeCoultre’s signature interchangeability system for an effortless change of style.

ENHANCED RELIABILITY AND PRECISION

Among the 1,400 calibres designed and produced in-house by the Manufacture Jaeger-LeCoultre since 1833, many have achieved notable longevity, thanks to their reliability and precision. However, even on these ‘pillar’ movements, the Manufacture’s engineers are constantly making improvements in a quest for enhanced performance.

The new versions of Calibre 846 – fitted in the Reverso Classic Small Monoface – and Calibre 844 in the Reverso Classic Small Duetto represent a total of 16 changes to the mechanisms. Among them, a new silicon escapement increases the movement’s efficiency by reducing friction, while also enhancing robustness and precision by reducing the negative impact of magnetism. With an increase in the barrel diameter – achieved without increasing the overall size of the calibre – power reserves have increased from 38 hours to 50 hours.

The latest versions of these four emblematic Reverso models perfectly represent Jaeger-LeCoultre’s commitment to safeguarding the collection’s unmistakable identity, evolving in new aesthetic directions that keep it eternally modern and constantly improving mechanical performance and precision.

• Enamelling mastery: 230 hours of work required to create the miniature-painted Grand Feu enamelling on the clock dials and decorative panels for the new Atmos Régulateur Enamel Colibris

• The Art of wood marqueterie: 52 slivers of wood just 0.6 mm thick, each individually hand-cut, tinted and lacquered before being meticulously applied to the panels for Atmos Régulateur Wood Marqueterie

• Celestial precision: precise reading of time on a regulator display, complemented by a calendar and a moon phase accurate to 3,821 years for Atmos Calibre 582

Jaeger-LeCoultre presents two new artistic interpretations of Atmos Régulateur Calibre 582, with the clock’s mechanism set in a transparent glass cabinet and framed by two dramatic decorative panels. The new clocks offer masterful demonstrations of two very different traditional craft techniques and creative approaches, qualities long nurtured by La Grande Maison alongside its pursuit of timekeeping precision. Atmos Régulateur Enamel Colibris is decorated with blossoms and hummingbirds (colibris in French) miniature-painted in Grand Feu enamel, and Atmos Régulateur Wood Marqueterie features a striking Art Deco-inspired design in wood inlay. The new clocks will be unveiled as part of an exhibition held by the Maison in Milan from 21–26 April 2026 during Milan Design Week, the world’s leading international design fair.     

TIME, TURNED INTO ART

The perpetual power of a 1928 vision: Thanks to its unique mechanism – a breakthrough and visionary concept invented in 1928 by Swiss engineer Jean-Léon Reutter and further developed by the watchmakers of LeCoultre & Cie (later Jaeger-LeCoultre) to make the revolutionary concept viable for series production, Atmos runs independently of human intervention, meaning that it needs no winding or other input of energy.

The clock of unrivaled efficiency: Known as the ‘clock that runs on air’, it is powered by a movement that effectively achieves perpetual motion by drawing its energy from barely perceptible variations in ambient temperature. This thermal energy is transformed into mechanical energy, which drives the movement of the balance wheel. The secret lies in a hermetically sealed, gas-filled capsule, which is connected to the clock’s drive spring by a membrane. The slightest temperature variation changes the volume of the gas, causing the membrane to expand and contract – ‘breathing’ like the bellows of an accordion – thus winding the spring and providing the minuscule amount of energy needed for the balance wheel to make its once-a-minute, back-and-forth oscillation. A temperature fluctuation of a single degree Celsius is enough to provide the clock with an operating autonomy of about two days; its energy consumption is so slight that it would require 60 million Atmos clocks to use the same amount of energy as a single 15-watt incandescent light bulb.

Where mechanism becomes art: The technical requirements of Atmos determine the distinctive architecture of its mechanism, which – being fully open to view within its glass cabinet – has anchored the clock’s strong aesthetic identity since the beginning, thus enabling experiments with design as early as the 1930s. The strength of this identity also makes Atmos an ideal canvas for artistic creativity.

Since the 1970s, Jaeger-LeCoultre has invited leading designers, alongside masters of traditional crafts – such as enamelling and marqueterie, first introduced in 1934 – to reinterpret the clock in their own style.

These explorations have extended to material experimentation, from ambrolite to all-glass constructions, as well as lacquer work and gem-setting.

Complications engineered for perpetual motion: Because the nature of Atmos mechanism requires its energy consumption to remain as low and as consistent as possible, it does not naturally lend itself to the addition of other timekeeping complications – the operation of which requires surges of higher energy. However, as the Manufacture continually worked to improve the clock’s performance over the decades, its engineers succeeded in developing the first Atmos with a moon-phase indication in 1992. Further complications have followed, including calendars, a celestial chart, Equation of Time, sunrise and sunset times, a regulator display and, most remarkably, a tellurium.

CALIBRE 582: A REGULATOR WITH 3,821-YEAR ACCURACY

Distinguished by its regulator display, Calibre 582, like all Jaeger-LeCoultre calibres, was conceived, designed and is entirely produced within the Manufacture. In keeping with the Maison’s pursuit of precision, Atmos Régulateur represents a modern continuation of a centuries-long lineage of scientific reference clocks. In clock and watchmaking, the regulator design originated not as an aesthetic choice but for the purpose of professional high-precision horology. Since the separation of the hour and minute displays enables exceptionally clear reading of smaller units of time, the regulator was often used as the reference for setting the time on other instruments. Continuing this emphasis on precision, the moon phase display of Jaeger-LeCoultre’s Calibre 582 is so accurate that it would take 3,821 years to diverge by just one day from astronomical reality.

The design of Atmos Calibre 582 is defined by circles within circles, with layered concentric indications organising the information clearly and intuitively. The large minutes ring anchors the architecture and is complemented by the smaller hours ring, a 24-hour ring and a circular display comprising the monthly calendar and moon-phase display. The symmetry of the displays is amplified by three large, open-worked guide rollers arranged in a pyramid formation: two lateral rollers, attached to arc-shaped bridges on the left and right of the mechanism’s centre line, support the suspended 24-hour ring, while a stabilising roller located at the 12 o’clock position ensures perfect positional stability.   

A CELEBRATION OF ARTISTIC CRAFTSMANSHIP

Limited edition: Produced in only 3 pieces, decorated with a graceful representation of hummingbirds, cherry blossoms and hydrangeas, Atmos Régulateur Enamel Colibris pays homage to the delicate beauty of nature’s flora and fauna, while shining a spotlight on both the technical watchmaking expertise of Jaeger-LeCoultre and the artistic savoir-faire nurtured by the in-house Métiers Rares™ atelier.  

A scene of great craftsmanship: The dial and panels alone required a total of 45 Grand Feu enamel firings (15 layers for the dial, and 15 layers for each of the two panels). Each firing presented a constant risk of breakage, potentially requiring the entire process to start from scratch. Miniature painting is usually performed on the tiny surfaces of wristwatches, however, these decorative panels – each measuring 196 mm x 105.2 mm – posed significant technical and artistic challenges and required extensive research and trials before the enamelling could begin.

Steel was chosen for the base material as it would provide greater resistance to the multiple firings at 800°C or more that are necessary to obtain and fix the desired enamel colours. First, a layer of contre-émail (‘opposing enamel’) had to be applied to the reverse side to help equalise the tension that would be created by the multiple layers of dark-green enamel to be applied to the front of the panels. For the large surfaces of the panels, the enamellers had to perfect the ‘dry enamelling’ technique of sifting powdered pigment onto the plates – rather like dusting the top of a cake with icing sugar – repeating the process multiple times to achieve the desired depth and uniformity of green.

After every layer, the panels had to be fired, then cooled and perfectly flattened – with every stage carrying the risk of bubbling, cracking or dust specks, any of which would ruin the entire work. Finally, when the background was completed, the miniature-painter could begin work, balancing the apparent contradictions of artistic flair and absolute precision. The work was done in multiple layers, each needing to be fired, with every firing again carrying the risk of irreparably damaging all that had been done before. To succeed in such work is testament to a degree of mastery that can be achieved only with countless years of experience.

An illumination of time, in gold: The miniature-painted image extends in an uninterrupted flow, from a rich floral display on the left-hand panel, across the enamelled minutes ring, to the opposite panel where three hummingbirds hover among the blossoms. To create the hour and minute rings, the silver base of the rings was hollowed out to form shallow troughs, which were then filled with multiple layers of enamel – again, with firing after every layer. Once satisfied with the depth and richness of colour, the enameller could begin miniature-painting the floral details. The final staged was the addition of dots to mark the hours and minutes, using gold leaf paillonné, an enamelling technique that consists of cutting tiny fragments of gold leaf into precise shapes, placing them in position, then covering them with layers of translucent enamel. The decorative enamelling on Atmos Régulateur Enamel Colibris required 230 hours to complete.

The craft of wood inlay: Atmos Régulateur Wood Marqueterie is a contemporary celebration of the age-old craft of wood marqueterie. This decorative art technique was perfected in the latter half of the 17^th century, particularly by Dutch and French master cabinetmakers, the most celebrated of whom was André-Charles Boulle, whose works – often combining wood with tortoiseshell, brass and other materials – for the French royal palaces are now highly valued museum pieces. 

An ancient discipline of patience: To create the decorative panels for this Atmos clock, the desired pattern – a trompe l’oeil effect of apparently infinite depth – was meticulously hollowed out from the metal base material, leaving only the fine and perfectly straight-edged ‘ribs’ that were rhodium-plated to highlight the geometry of the pattern created by the wood inlay.  Then came the challenge of finding the desired wood veneers – mostly walnut – with complementary grains. In a process that required 50 hours to complete, 52 fine slices of wood veneer, each no thicker than 0.6 mm – as fine as a rose petal – were cut to shape with micron-precision to fit seamlessly into the prepared spaces, then hand-tinted in shades of blue ranging from light grey-blue through sky blue to deep ocean blue. Once the wood was inlaid to complete the pattern, the surface was varnished and polished, transforming the clock into a modern work of art with strong echoes of the Art Deco period when Atmos was born.

A play of geometric illusion: The blue tones of the marqueterie are complemented by the dial displays: the large minutes register is lacquered in blue, with applied, rhodium-plated indexes at five-minute intervals. The palette is reversed on the hours register, with blue-lacquered indexes and shiny rhodium-plated elements contrasting with a silvery opaline background. The moon phase display continues the theme, with a blue lacquered sky providing the background for a polished moon, which emerges from behind ‘clouds’ decorated with azurage to create a finely textured finish. Atmos Régulateur Wood Marqueterie will be produced in a limited edition of five pieces.

More than just a remarkable timepiece that runs on air, Atmos is an objet d’art that has fascinated admirers of both technical and artistic creativity for more than nine decades and the splendour of these two new interpretations ensure the continuity of Atmos legend for many generations to come.

A STORY TOLD IN SIX CHAPTERS

‘The Perpetual Timekeeper’ tells the fascinating story of the Atmos as well as showcasing Jaeger-LeCoultre’s rich legacy of creative design and technical ingenuity in a wide range of other timekeeping objects.

CHAPTER I: ATMOS, THE STORY

The dream of perpetual motion has fascinated humanity for centuries, expressing a deeper desire to master time, energy and autonomy. This long-standing quest took a decisive step in 1928 when a Swiss radiological engineer, Jean-Léon Reutter, succeeded in developing a prototype clock that came closer to perpetual operation than any other mechanism yet created. Known as the Atmos 0, it was powered not by rewinding or any other conventional energy source, but by subtle variations in air temperature, thus creating the unprecedented concept of a timekeeper designed to operate autonomously.

Early commercial versions revealed technical limitations, yet the invention’s promise remained undeniable. Jacques-David LeCoultre realised that, despite the brilliance of the invention, the mechanism required exceptional watchmaking skill to make it fully viable. He recognized its poetic force and mechanical potential, inviting Reutter to join forces with LeCoultre & Cie, initiating a collaboration that united visionary invention with high watchmaking expertise.

Refining the intricate mechanism and enhancing its reliability, this passionate collaboration first resulted in the Atmos I in 1932. This model featured apparent perpetual motion, on principle, able to run indefinitely with minimal external input as long as the ambient air temperature fluctuated, creating the illusion of endless operation.

Until 1938, early Atmos models used a mercury-driven motor block: a system of communicating vessels in which thermal expansion and contraction powered the movement. However, mercury’s fragility made transport difficult and limited reliability. In response, LeCoultre replaced it with a gas-filled capsule (ethyl chloride) and centralized production, while the underlying mechanism initially remained unchanged – known as Calibre 30A, as used in the Atmos I and II.

Powered solely by subtle variations in ambient temperature, it could transform a change of just 1°C into around 48 hours of autonomy, enabling the clock to function indefinitely without any manual input.

Soon adopted as a diplomatic gift, earning the name 'President’s Clock,' today’s Atmos Classic remains its dignified heir, preserving the timeless design codes that made the Atmos a symbol of prestige, continuity and enduring precision.

CHAPTER II: ATMOS, THE MÉTIERS RARES^TM

With its intricate mechanism and the mesmerisingly slow beat of its annular balance wheel, the Atmos clock transcends mere timekeeping; as an objet d’art rooted in the elegant minimalism of its Art Deco origins yet constantly evolving, it is a natural canvas for artistic expression.

Usually displayed within a glass dome or crystal case, the distinctive architecture of the Atmos movements has anchored a strong visual identity that is celebrated as much as the time it measures, embracing diverse designs while retaining its core spirit. Since the 1970s, Jaeger-LeCoultre has revived the spirit of aesthetic experimentation that marked the first decade of the Atmos in the 1930s. A series of collaborations with masters of decorative crafts have elevated Atmos clocks into works of fine art, and leading contemporary designers have reimagined the Atmos in their own style, while always preserving the clock’s unmistakable identity.

CHAPTER III: ATMOS, THE COMPLICATIONS

The Atmos’ apparently magical way of working is also a limitation: because the mechanism produces only a very small amount of energy (a single 15-watt incandescent light bulb consumes the energy equivalent to 60 million Atmos clocks), there is not enough power left over to drive additional functions. Visitors to the exhibition will discover how Jaeger-LeCoultre’s engineers solved this problem in 1982 with a new movement – Calibre 540 – that made it possible to integrate complications with only an infinitesimal increase in energy consumption. Having discovered that the ideal complications are those based on the long, slow cycles of the astronomical phenomena that lie at the origin of time measurement – such as the moon phases and seasons – they developed the first moon-phase Atmos at the end of the 1990s. In 2022, Jaeger-LeCoultre’s watchmakers crafted the most complex Atmos clock ever conceived: the Atmos Hybris Mechanica Calibre 590, nicknamed the Atmos Tellurium as it incorporates a contemporary version of the tellurions – three-dimensional mechanical mobiles that precisely reproduce the true cycles of the Earth, Sun, and Moon – invented during the Renaissance.

CHAPTER IV: CLOCKS, THE WATCHMAKING OBJECTS

In the 1920s, personal access to time remained limited, positioning the timepiece as an accessory reserved for a privileged few. Jaeger-LeCoultre reimagined the clock by transforming familiar objects of daily and professional life. Thus, desk accessories, lamps and architectural miniatures gained the ability to measure and display time. By embedding timekeeping functions into useful, everyday items, the Maison blurred the boundary between utility and watchmaking, transforming the ordinary into the extraordinary through imaginative design and meticulous craftsmanship. Conceived to integrate naturally into their environment rather than commanding attention as standalone objects, these timekeepers were often unexpected in form or playful in reference, blending refinement and surprise. Designed to be handled and lived with, set on a tabletop, read from both sides or slipped into a purse, these objects reflect a new relationship with time that is intuitive and naturally woven into the rhythm of daily life.

CHAPTER V: CLOCKS, THE TRAVEL OBJECTS

As the 20^th century progressed and modern life was increasingly defined by mobility, Jaeger-LeCoultre responded by transforming clocks into portable objects designed to accompany their owners wherever the journey led. Marrying technical expertise to aesthetic elegance and creativity, the Maison’s nomadic timekeepers include unexpected and immaculately crafted designs, sometimes incorporating functions such as barometers and thermometers. From the 1930s onwards, travel clocks embodied this vision of mobility. Miniaturised and integrated into mirrors, leather cases or folding table clocks, they combined mechanical reliability with practical design solutions adapted to movement. Designed to be handled and transported, these objects reflect an era fascinated by precision, progress, mechanical reliability and functional elegance. The introduction of the Memovox mechanical alarm in 1950 transformed time from a passive display into an active signal. Adapted into watches, desk clocks and travel objects, Memovox embodied a philosophy of time that alerts, guides and reassures.

CHAPTER VI: CLOCKS, THE DESIGN OBJECTS

From the 1920s onwards, fuelled by social, economic and technological change, a tremendous burst of creative energy expressed itself through a new design language that shaped every aspect of life – from architecture and graphics to modes of transport, household products and even industrial machinery. Clocks were no exception and Jaeger-LeCoultre embraced the new spirit of modernity, rethinking both form and display. Clocks became playful, surprising and sometimes provocative – objects of expression designed as a style statement as much as a display of the time. From Art Deco table clocks to boldly graphic compositions of the 1960s, each creation reflects a dialogue between watchmaking expertise and the spirit of its time. Mechanical precision remains indispensable, yet it is wrapped in freedom of interpretation, shape, material and style. Conventions are questioned: hands shift off-centre, dials rotate, proportions stretch or contract. These objects invite conversation, spark curiosity and transform the simple act of reading the hour into a rich experience.

EXCLUSIVE NOVELTIES: THREE MARC NEWSON DESIGNS AND TWO EXCEPTIONAL ATMOS PIECES

A creative collaboration with Marc Newson: Jaeger-LeCoultre and the celebrated industrial designer Marc Newson have periodically collaborated since 2008, pooling their expertise and creative energy to produce new interpretations of the Atmos – a clock that the designer describes as ‘a complex and magical object’. In 2008 they released Calibre 561; in 2010 it was Calibre 566; and in 2016 came the first iteration of Calibre 568. Famous for his work, ranging from furniture to luggage, a surfboard and a superyacht – Marc Newson has a longstanding interest in timepieces and has been fascinated by the Atmos clock since he first saw one in his early teens.

During ‘The Perpetual Timekeeper’ Jaeger-LeCoultre will unveil three new designs by Marc Newson, alongside a curated selection of his exceptional furniture creations: a new version of the Atmos Tellurium, a new interpretation of the Atmos Calibre 568 that he designed in 2016 and a new Travel Clock inspired by the Maison’s iconic Memovox alarm wristwatches.

A celebration of craftsmanship: The preservation and perpetuation of traditional decorative handcrafts – widely used in watchmaking until the end of the 19^th century but often forgotten as tastes changed during the 20^th century – has long been a core value at Jaeger-LeCoultre. As a fine watchmaking Maison, it takes its responsibility to nurture these crafts seriously, and as one of the few watchmaking Maisons to have its own Métiers Rares™ atelier in-house, it constantly encourages their evolution by applying them to different timepieces, in new ways. Shining the spotlight on the decorative crafts, two new Atmos models will be unveiled during the exhibition, one showcasing miniature painting in Grand Feu enamel and the other paying homage to the traditional craft of wood marqueterie.

An exclusive Milan Design Week exhibition: ‘The Perpetual Timekeeper’ expresses a singular philosophy of time. At once scientific, functional and artistic, Atmos and the watchmaking objects that surround it form a coherent universe where design, mechanics and human invention shape a vision of time that is durable, thoughtful and deeply connected to the world around us.

‘The Perpetual Timekeeper’ will run from 21–26 April 2026 at Villa Mozart, via Mozart 9, 20122 Milan and is open to the public free of charge from 10.00 to 18.30 daily. Visitors may register online in advance at https://bit.ly/ThePerpetualTimekeeper or on arrival at the exhibition.

In the latest chapter of its ongoing collaboration with industrial designer Marc Newson, Jaeger-LeCoultre unveils the Memovox Travel Clock. Drawing on the La Grande Maison’s rich heritage of travel timepieces, the design reimagines the ideal companion for the modern traveller. Compact enough to rest in the palm of the hand yet defined by a strong visual presence, it pairs the lightness of a titanium case with the tactile warmth of a Schedoni leather pouch. The Memovox Travel Clock will be unveiled as part of The Perpetual Timekeeper, an exhibition presented by Jaeger-LeCoultre from 21 to 26 April 2026 during Milan Design Week, the world’s leading international design fair.

AN INTERWOVEN HERITAGE OF TIME AND TRAVEL

Jaeger-LeCoultre's rich watchmaking heritage extends to the realm of travel, marked by the creation of Dual Time and World Time wristwatches, as well as travel clocks in various forms. Marrying this technical expertise with aesthetic elegance, Jaeger-LeCoultre has created a legacy of nomadic timekeepers distinguished by unexpected, meticulously crafted designs – some enhanced with functions such as thermometers and barometers.

This story is inextricably linked to the iconic Memovox alarm calibre, introduced in 1950. Announced by an advertisement headlined “Memovox reminds, notifies, and wakes up”, the Memovox (derived from the Latin for ‘voice of memory’) was initially designed for wristwatches to help businessmen remember their appointments. Given its utility, it was natural that Jaeger-LeCoultre should adapt the Memovox complication for a series of desktop and travel clocks from the early 1950s onwards. In both watches and clocks, the Memovox Calibre translates into a distinctive dial, with a triangular pointer at the edge of a mobile central disc indicating the alarm time, and a distinctive Memovox sound reminiscent of a traditional school bell.

A NEW COLLABORATION WITH MARC NEWSON

Jaeger-LeCoultre and Australian-born industrial designer Marc Newson have collaborated since 2008, combining their expertise to reinterpret the Atmos – an object the designer describes as both “complex” and “magical.” This creative dialogue has given rise to successive calibres: 561 in 2008, 566 in 2010 and the first iteration of 568 in 2016. Renowned for his multidisciplinary practice, Marc Newson has long been fascinated by the Atmos, first encountered in his early teens. Guided by its timeless character, he introduces precise design interventions that respect and preserve the integrity of the object.

His approach explores unexpected uses of materials and challenges technical conventions. Rooted in a deep appreciation for analogue objects, his vision aligns with a commitment to longevity: creations designed to endure, both in function and in form.

FUNCTION AND FORM IN PERFECT HARMONY

A master in the marriage of function and form, Marc Newson brings a fresh eye to the technical and visual lineage of the Memovox, creating a contemporary object that is as aesthetically pleasing as it is practical and easy to use. In a symbiotic union of skills, Jaeger-LeCoultre harnessed its watchmaking expertise to bring the designer’s vision to life, developing several technical innovations to make it possible.

The clock is powered by a completely new, manually wound movement, Calibre 256, featuring the signature Memovox complication. Like all Jaeger-LeCoultre calibres, it was conceived, designed and produced entirely in-house. To eliminate concerns for travelers about rewinding the clock, Calibre 256 offers an exceptionally long power reserve of 12 days thanks to two large barrels dedicated to the timekeeping function. An additional third barrel is used exclusively for alarm mechanism.

Inspired by the traditional Memovox dials, the dial design plays on circles within circles, anchored by a distinctive power reserve indicator, shown in narrow apertures that form a broken circle around the large Arabic numerals. One day of power reserve corresponds to one hour on the dial, so that when the barrel is fully wound, all 12 indicators are orange. Starting from 12 o’clock and moving in an anti-clockwise direction, with each day that the power reserve reduces, the corresponding indicator turns blue.

The apparent simplicity of the display belies the technical feat behind it – a new mechanism developed and patented by Jaeger-LeCoultre comprising two intertwined helicoidal rings: a mobile ring in orange and a fixed ring in blue.  Surrounding the mobile central disc of the dial, which carries the Memovox’s emblematic triangular alarm pointer, minutes are marked on a fixed ring. With a narrow bezel and striking orange-and-blue colour palette adding a contemporary note and enhancing legibility, the hands and the alarm triangle are coated in SuperLuminova® for maximum visibility in low light.

Forged from the ethereal strength of titanium, the Memovox Travel Clock, a perfect sphere of lightness and resilience, embraces a diameter of 69 mm and a slender profile of 18 mm. Continuing the theme of circles within circles and the complete absence of visual clutter, a folding stand is integrated into the caseback, for use on a desk or bedside table. Concealed beneath the bezel, a peripheral winding crown offers the tactile pleasure of manual winding, time-setting and alarm setting – the desired function chosen by an integrated selector button.

The orange-and-blue colour scheme is echoed on the case back, with a central indicator for the alarm power reserve (orange turning to blue as it runs down) and a blue band on the underside of the winder, bearing several engravings, including the year edition and the series number of the clock, for which production is limited to 100 pieces per year.

A CASED DISPLAY: A DESIGN THOUGHT THROUGH TO THE FINEST DETAIL

To complete the Memovox Travel Clock, Marc Newson collaborated with Schedoni, an historic, family-run leather workshop located in the heart of Modena and renowned for its work on classic Italian sports cars of the mid-20^th century, as well as its signature leather-molding techniques. The clock is nestled within its own travel pouch, for its journey. This pouch, in turn, finds its place within a comprehensive travel pack, thoughtfully designed to also embrace three beloved wristwatches. Completing this ensemble, a curated kit of essential tools awaits: a discerning magnifying glass, a precise strap removal tool, and a screwdriver.

A dedicated display stand also accompanies the timekeeper, ideal for use when the clock is ‘at home’ on a desk or bedside table for an extended period.  Each of these companions – the pouch, the travel pack, and the elegant display stand – is meticulously crafted by the Italian luxury Maison Schedoni. Made from the finest tan-coloured, natural open-pore cowhide leather, their surfaces graced with the artistry of contrasting beige hand-stitching, a testament to enduring quality and design.

In 2026, Jaeger-LeCoultre unveils a new interpretation of Atmos Calibre 568, created in collaboration with celebrated industrial designer Marc Newson. The new clock is a sequel to the designer’s initial version of the clock in 2016 and features a new colour palette as well as added technical functions – displays of sunrise and sunset times and Equation of Time – as well as an exceptionally precise moon phase display. This modern icon will be unveiled as part of Jaeger-LeCoultre’s Atmos exhibition during Milan Design Week, from 21-26 April 2026.

WOUND BY AIR, A MARVEL OF PERPETUAL MOTION

With a unique mechanism invented in 1928 by Swiss engineer Jean-Léon Reutter and refined for series production by the watchmakers of LeCoultre & Cie (later Jaeger-LeCoultre), Atmos operates independently of human intervention, requiring no winding or external energy input. Known as the ‘clock that runs on air’, it is powered by a movement that effectively achieves perpetual motion by drawing its energy from barely perceptible variations in ambient temperature.

This thermal energy is transformed into mechanical energy, which drives the movement of the balance wheel. The secret lies in a hermetically sealed, gas-filled capsule, which is connected to the clock’s drive spring by a membrane. The slightest temperature variation changes the gas volume, causing the membrane to expand and contract – 'breathing' like the bellows of an accordion. This action winds the spring, providing the minuscule energy needed for the balance wheel's once-a-minute, back-and-forth oscillation. A temperature fluctuation of a single degree Celsius is enough to provide the clock with an operating autonomy of about two days.

The technical requirements of the mechanism determine the distinctive architecture of the Atmos mechanism, which has anchored the clock’s strong aesthetic identity since the beginning. This strong identity also makes the Atmos an ideal canvas for artistic creativity and since the 1970s, Jaeger-LeCoultre has invited a series of leading designers, as well as masters of traditional artistic crafts, to reinterpret the clock in their own style.

A NEW COLLABORATION WITH MARC NEWSON

Jaeger-LeCoultre and Australian-born industrial designer Marc Newson have collaborated since 2008, combining their expertise to reinterpret the Atmos – an object the designer describes as both “complex” and “magical.” This creative dialogue has given rise to successive calibres: 561 in 2008, 566 in 2010 and the first iteration of 568 in 2016. Renowned for his multidisciplinary practice, Marc Newson has long been fascinated by the Atmos, first encountered in his early teens.

His approach explores unexpected uses of materials and challenges technical conventions. Rooted in a deep appreciation for analogue objects, his vision aligns with a commitment to longevity: creations designed to endure, both in function and in form.

PURITY, LIGHT AND PRECISION

A distinct visual identity: Marc Newson conceives the Atmos Designer Calibre 568 as an expression of clarity and precision. Stripped to its essentials, the design emphasises lightness, transparency, and legibility, allowing the movement to appear freely suspended within its hand-crafted Baccarat crystal case. In his 2026 interpretation, the designer preserves the clock’s particular purity while also adding new functions and a distinct visual identity. The monochromatic palette draws attention to the intricate mechanics behind the sunrise and sunset indications and the Equation of Time, making the complexity of the movement immediately visible.

The selection of the design's material naturally led to crystal. Its inherent aesthetic qualities and unique finish prompted Marc Newson to choose it for his project. The French company Baccarat, a celebrated traditional crystal manufacturer founded in 1764, is one of the very few with the necessary technical expertise to create the cabinet as envisioned: a square with rounded corner – evocative of a slowly melting ice cube – with absolute transparency and apparent fragility belying the structural strength required to support the weight of the mechanism. 

A technically complex feat: Requiring almost four years of research and development, the mouth-blown cabinet is a single, solid piece of crystal – except for a removable sheet of glass that allows access to the mechanism if necessary – its thickness reduced to just 13 mm in some places. After blowing, the red-hot crystal is carefully contoured into the envisioned shape using a two-sided mould to better control the cooling process and preserve the desired tolerances.

A floating architecture: Central to the clock’s architecture, the crystal must be extremely strong and stable to support the movement while giving the illusion that it floats in space within case. Visible only from the back of the clock, the four attachment points for the movement – rather than three as on traditional Atmos clocks – create symmetry and draw attention to the beautifully finished components.

Calibre 568’s dial is optimised for easy legibility with the time effortlessly read thanks to the simplicity of the Arabic numerals, printed in white on a black-tinted sapphire crystal disc and encircled by a minute track. The months are marked, in French, on an inner circle. The displays for the new complications maintain the simplicity – but appearances obscure the complex technical reality of this objet d’art. Appearing as a concentric ring between the months and hours, the times of sunrise and sunset are marked on a sapphire crystal disc, each indicated by a small arrow on the edge of the disc. The equation of time – the difference between the current mean time and solar time – is depicted as an ellipse surrounding the hand arbour, which moves to display the correct +/- minutes on the scale behind it. This collection will feature three distinct Atmos clocks, each meticulously designed to represent a different latitude: 30°, 40°, and 50°.

An exclusive production: Each timepiece in this exclusive limited production of just 50 pieces worldwide per year will not only showcase the intricate 'Equation Of Time' but will also elegantly display the precise sunset and sunrise times specific to its designated latitude. While the moon phases are displayed on a smoothly finished disc at 6 o’clock, the calculations for the equation of time, sunset, and sunrise on these limited production pieces are precisely tailored to their respective geographical latitudes. Jaeger-LeCoultre’s watchmakers have been able to achieve a remarkable degree of precision in the display, to only one day of discrepancy in every 4,087 years. If the Atmos is left unattended and running continuously, its displays will remain correct for this entire period – the only exception being bi-annual adjustments for Daylight Savings Time in countries that use the protocol.

For a new moment in time, Marc Newson’s vision combined with the Ateliers of La Grande Maison, has yielded a timeless objet d’art, an infinite clock that seems to defy the physics of time altogether. With its translucent beauty and seemingly delicate simplicity, the Atmos 568 by Marc Newson offers an enduring showcase for time to flow in perpetuity.

His approach explores unexpected uses of materials and challenges technical conventions. Rooted in a deep appreciation for analogue objects, his vision aligns with a commitment to longevity: creations designed to endure, both in function and in form.

A NEW DESIGN CAPTURES THE BEAUTY OF THE SOLAR SYSTEM

Calibre 590 is the most complicated Atmos movement ever created, reproducing the cycles of Earth, the Sun and Moon with great precision, in three-dimensional form. Jaeger-LeCoultre named this clock the Tellurium in homage to the three-dimensional mobiles of the same name invented during the Renaissance after Copernicus introduced his heliocentric model of the solar system; a tellurium reproduces the rotation of Earth and its orbit around the Sun as well as the orbit and rotation of the Moon around Earth. Starting in the 18^th century, watchmakers thought to combine the tellurium with elaborate clocks.

A celestial globe: Inspired by the beauty and mystery of the cosmos beyond Earth’s solar system, Marc Newson has designed a new cabinet for the Atmos Tellurium: a perfect globe of glass engraved with a map of the 64 constellations visible mainly in the Northern Hemisphere that is inset with 539 cabochon-cut sapphires (32K) representing the principal stars. Marc Newson’s work as a designer is distinguished by his use of materials in new ways that often require the development of new processes, usually through a process of experimentation. In the case of the Atmos Tellurium, a great deal of research and many iterations were required to achieve the illusion of “invisible setting”, with the gemstones inset directly into the external surface of the glass, with their rounded forms creating a subtle three-dimensional effect.

The heavenly objet d’art rests on a laser-engraved plate reproducing the surface of the moon and sits on a circular, ribbed base of dark-blue anodised aluminium that matches the blue of the anodised dial.

Artistry in motion: Commensurate with the extraordinary complexity and technical sophistication of Calibre 590, the mechanism’s key components are highlighted with a variety of decorative finishes. The three-dimensional Earth is miniature-painted by hand in Jaeger-LeCoultre’s Métiers Rares^TM atelier to add depth and detail; laser engraving recreates the surface of the Moon and meteorite – a material that has literally fallen from space – is inlaid on the earth-moon ring.  For his reinterpretation of the Atmos Tellurium, Marc Newson chose more contemporary finishes to create an aesthetic tension that perfectly balances tradition and modernity: galvanised aluminium for the hours-and-minutes ring and brushing on the movement plates and balance wheel.

The entire clock is supported on a plinth of blue calf leather, which forms part of a modular case that can be used in various configurations for displaying or storing the clock. Designed by Marc Newson, the case is handcrafted by Serapian, the renowned Milanese leather workshop, in its signature Mosaico pattern – created by a hand-weaving process developed by the Italian firm in 1947.

ETERNITY UNDER GLASS

Introducing extraordinary functions: As well as incorporating the functions of a tellurium, Calibre 590 adds displays for the corresponding months and seasons as well as a zodiacal calendar. As the Moon rotates, it reproduces its phases with exceptional precision, with a discrepancy of only one day every 5,770 years.

A calendar in motion: The clock dial showing hours and minutes is encircled by a two-layered ring: the visible upper layer is immobile, marked with an hour-and-minute track and the names of the seasons. The second, hidden layer is marked with the months and revolves, revealing the name of the current month in an aperture at 6 o’clock. This peripheral ring encircles a translucent blue sapphire crystal disc that is laser-engraved with symbols representing the zodiac signs. At the centre of this disc, the Sun is represented by a burst of sunrays in polished 18K pink gold, the longest of which points to the current zodiac sign.

Earth and Moon in harmony: Close to the peripheral ring, balanced by a wedge-shaped counterweight, a smaller circle of meteorite frames a transparent light-blue sapphire disc into which revolving, spherical depictions of Earth and the Moon are set. This earth rotates on its axis in 24 hours, the length of one civil day, providing the day-night indication as it revolves. At the same time, the moon orbits this earth in one synodic month, revolving on its own axis to display its phases. Defined by one complete cycle of moon phases, an average synodic month is 29 days, 12 hours, 44 minutes and 2 seconds in length.

Tracking the seasons with precision: The earth-and-moon subdial orbits around the central sun, making a complete rotation in one year and indicating the seasons as it turns. Jaeger-LeCoultre’s watchmakers have succeeded in establishing a cycle of 365.2466 days, which is so close to the 365.2425 days of the Gregorian calendar that it varies by only one day in 390 years, meaning that so long as the clock remains wound, the calendar will not need adjusting until the year 2416.

A true work of art, the Atmos Tellurium Calibre 590 by Marc Newson is a visual and technical tour de force that replicates the majesty of our corner of the galaxy with exceptional precision, in strikingly beautiful style.

The Valley of Inventions pays homage to an isolated valley where, 600 years ago, refugees from elsewhere in Europe found safe haven. Life followed a strict seasonal rhythm: in summer, the Vallée de Joux revolved around alpine farming and dairy production; in winter, when harsh conditions brought agriculture to a standstill, farmers turned to metalworking within their chalets. Necessity fostered ingenuity, patience and precision led them to craft increasingly intricate objects - a path that would ultimately give rise to watchmaking.

Ten generations after Pierre LeCoultre’s arrival in the Vallée de Joux, in the early 19^th century, a self-taught watchmaker, Antoine LeCoultre, began inventing machines that laid the foundations of modern watchmaking, enabling the measurement and cutting of components to an unprecedented degree of precision. From the first LeCoultre watchmaking atelier in 1833, this spirit of inventiveness has defined the Maison. A succession of technical breakthroughs produced calibres sought after by many leading watchmaking names, earning Jaeger-LeCoultre its designation as The Watchmaker of Watchmakers™. With more than 430 patents to date, this legacy of invention continues to guide the Maison’s pursuit of precision, today and into the future.

Capturing the spirit of invention in the booth

Creating a richly evocative experience of the Maison’s origin-story of invention, the Watches and Wonders booth was inspired by the frozen silence of the landscape and forests in winter, contrasting with the warmth and shelter of the chalets where the valley’s early inhabitants began to hone their craft – first as blacksmiths and later as watchmakers. From the ice of the landscape to the fire of the forges.

The architectural layout draws the eye to the centre of the booth, where a spectacular pine tree, sculpted from ice, soars to almost four metres in height.

Panels of frosted and bevelled glass continue the icy theme, contrasting with the warmth of natural materials, particularly golden-toned pine wood, that pay homage to the valley. Set on three levels, the booth invites visitors to immerse themselves further in the story of invention and precision, and to discover the newly launched timepieces as well as the entire current collection.

NEW MODELS: KEEPING ALIVE THE SPIRIT OF INVENTION

The pursuit of precision

From aesthetic reinterpretations of existing models to entirely new calibres, the timepieces presented at Watches and Wonders Geneva 2026 express different facets of precision.

A chronometry quest: The Master Control Chronometre sets a new benchmark in chronometric performance, presented on an integrated metal bracelet. This commitment extends even further, as the new Jaeger-LeCoultre HPG seal - High Precision Guarantee - attests to its superior quality and finishing. The Master Control Chronometre collection makes its debut with three models, each offering a different complication: a date display, a perpetual calendar and a combination of power reserve and date – the latest driven by a new in-house movement, Calibre 738.

Upmost precision: The Gyrotourbillon À Stratosphère pushes the boundaries of precision, with its three axes covering 98% of possible positions. Its construction, for which patent applications were filled, comprising 189 components, achieves extreme lightness, as the triple-axis tourbillon weighs a mere 0.78 grams. The Calibre 178 movement is elevated by Métiers Rares™ finishes - including guillochage, enamel, and lacquer - transforming its intricate components into a dial-like masterpiece.

State-of-the-Art complication: Housing the world’s thinnest automatic minute repeater tourbillon, the Master Hybris Mechanica Ultra Thin Minute Repeater Tourbillon is presented in a new 60-part case and powered by Calibre 362. Its open-worked architecture and sapphire bridges reveal a captivating view of the calibre’s 593 components, whose assembly alone required seven weeks.

Award-winning movement, reinvented: The Master Grande Tradition Tourbillon Jumping Date introduces a new movement architecture that creates a fresh aesthetic for Calibre 978. In 2009, this calibre won the first modern-era chronometry competition. An open-worked dial highlights the tourbillon, distinguished by a rounded 18K white gold (750/1000) bridge and a signature “jumping” date mechanism. The sophisticated 42 mm case, comprising 60 components, captures the refined design codes of the Grande Tradition collection.

The limitless Métiers Rares™ know-how

Since the establishment of the Métiers Rares™ Atelier in 2016, master enamellers, engravers, gem-setters and guillocheurs have worked side by side within the Manufacture, combining their skills to give rise to genuine works of art - each one the expression of human ingenuity pushed to its highest level.

Nature, an endless source of inspiration: La Vallée des Merveilles™, a new series of capsule collections, celebrates world’s most enchanting landscapes, from the world’s last pristine places to the artistry of the most beautiful gardens. The first capsule presents three new editions in the Reverso One collection, inspired by Hawaii’s tropical splendour and the delicate beauty of Japan, showcasing the exceptional craftsmanship practised within Jaeger-LeCoultre’s in-house Métiers Rares™ atelier. These editions feature gold-leaf paillonage, champlevé enamelling, and gem-setting in limited editions of 20 pieces each.

Japanese grandeur, miniaturized: Unveiling four new Reverso Tribute Enamel ‘Hokusai’ 10-piece limited editions that pay tribute to the expertise of the Métiers Rares™️. Each showcases grand feu enamel miniatures inspired by Hokusai’s iconic ‘Waterfalls’ series, complemented by intricate hand-guilloché dials and miniature-painted case backs. Each timepiece represents nearly 100 hours of dedicated craftsmanship, paying profound homage to Japan’s most celebrated 19^th-century artist.

The new boundary in the pursuit of precision

Given the Manufacture’s constant drive for innovation, the new Master Control Chronometre introduces the new Jaeger-LeCoultre seal: ‘HPG’ High Precision Guarantee, which certifies not only the refined aesthetic finishes but also the high precision of the timepiece. This Jaeger-LeCoultre certification is met through an even more stringent protocol, for which a patent has been applied for, that rigorously tests cased-up watches, replicating the daily wear of a watch and evaluates performance against four critical elements of daily wear: altitude, shocks, positions, and temperature. By integrating these diverse conditions, the patent-pending method ensures that the watch's intricate mechanisms maintain their optimal chronometric accuracy, not just in ideal conditions, but throughout the full spectrum of a wearer's life. Beyond the HPG seal and to exemplify the accuracy of this new test, all Master Control Chronometre also receive the prestigious COSC certification of timekeeping accuracy – which is mandatory for the right to use the word ‘Chronomètre’ or the English ‘Chronometer’.

EXPERIENCES: EMBRACE THE QUEST FOR INVENTION

Presenting live demonstrations

On the booth, traditional alpine-inspired chalets host live demonstrations of four high-watchmaking skills by master artisans from the Manufacture. Two of these skills focus on intricate watch mechanisms, while the other two showcase artistic crafts dedicated to decorating watch cases and dials, each performed with meticulous precision.

Guillochage: the creation of patterns by hand-engraving precisely drawn and closely packed lines using an antique hand-operated machine called a rose engine lathe, that only two persons from the Manufacture know how to master.

Bevelling: an entirely hand-crafted process involving the filing and polishing of the edges of movement components, to create a sloping face that reflects the light from its mirror-smooth surface.

Watchmaking: a deep dive into the regulating organs of a timepiece, with a particular focus on the mechanical complexity of the Gyrotourbillon À Stratosphère. Experts from the Research & Development Laboratory, comprising both the construction and innovation teams, together with watchmakers will decode the intricate architecture of this multi-axis system, while also showcasing the cutting-edge development of various balance-spring geometries.

Enamelling: a demonstration will feature miniature painting, one of the most demanding enamelling techniques. Illustrated through four new Reverso Tribute Enamel Hokusai editions, this showcase will highlight the meticulous application of enamel. Each coat is applied, layer after layer, before the next, revealing the techniques that bring painterly depth to the dial.

Offering a new gastronomic journey at Le Chalet

In the latest collaboration under the Made of Makers^TM programme, Jaeger-LeCoultre has commissioned the gifted Swiss chef Gilles Varone to create a new gastronomic experience for invited guests at Le Chalet, located within the booth. Taking on a gastronomic challenge centred on a controversial ingredient, cheese, the two-Michelin-star chef has devised four bites that deliver sensory surprises and elevate the most classical Swiss ingredient to new heights. Complemented by beverages specially created to enhance the tasting experience, the four bites reinvent the traditional concept of a cheeseboard, showcasing Gilles Varone’s reverence for natural ingredients through subtle flavour harmonies, unconventional textures and visually refined presentations.

Experiencing immersive cinema

A multi-sensory show presented every half hour narrates the story of the place, the people and the inventions that shaped the Manufacture. Inspired by multi-sensory cinema technology and designed to be viewed ‘in the round’ by all visitors, both inside and outside the booth. The show features synchronised physical and environmental effects that make audiences feel as if they are participating in the show, rather than simply watching it.

For visitors to the Jaeger-LeCoultre booth who wish to deepen their knowledge, guided tours are available to complete the experience. Watches and Wonders will take place in Geneva from 14 – 20 April 2026 and is open to the public from Saturday April 18 to Monday April 20.
