• Refined ultra-thin elegance: a new case in 18K pink gold (750/1000); smaller size, with fully polished case, bezel and curved lugs

• Emblematic in-house movement: finely finished and highly reliable Calibre 925, providing 70 hours of power reserve

• Traditional finishes with vintage dimensions: a new slim case measuring 36 mm and paying tribute to the proportions of 1950s round watches

Jaeger-LeCoultre presents the Master Ultra Thin Moon with its new 36mm case in 18K pink gold (750/1000). Contrasting with the warm shine of the polished pink gold, the subtle texture and cool silvered colour of the dial bring a fresh dimension to the timeless aesthetics and technical virtuosity for which the Master Ultra Thin collection is renowned.

A QUINTESSENTIAL DRESS WATCH FOR MODERN AESTHETES

Inspired by the Maison’s remarkable legacy of ultra-thin watches – created from the early 1900s onwards – the Master Ultra Thin collection was conceived as a quintessential dress watch for the 21^st century. Timeless and classic with clean lines, polished surfaces and long, curving lugs, the Master Ultra Thin expresses an understated sophistication with a touch of modernity. Its thin calibres attest to almost 200 years of continuous mechanical innovation and excellence within Jaeger-LeCoultre’s fully integrated Manufacture-Atelier in Switzerland’s Vallée de Joux.

A DISTINCTIVE NEW CASE, WARM AND REFINED

The new smaller 18K pink gold (750/1000) case brings a warmer, refined and timeless allure to the Master Ultra Thin Moon. The warm tones of the polished case surfaces are echoed by the gilt hour markers and faceted hands.

Complementing the sleek lines of the 36 mm case, the dial layout is a finely judged exercise in symmetry and balance. Anchored by the date and moon-phase display at 6 o’clock, it is highly legible and perfectly integrated in every detail. The shape of the trapezoidal indexes is echoed by the Dauphine hands, one facet of which is satin-brushed and the other polished, creating a visually intriguing play of light from different angles.

An alligator strap in black, paired with a pin buckle in 18K pink gold (750/1000), can be easily interchanged according to the wearer’s wishes, adding even more versatility to this sophisticated, contemporary timepiece.

A SIGNATURE COMPLICATION DRIVEN BY AN EMBLEMATIC MANUFACTURE MOVEMENT

The Master Ultra Thin Moon features a combined moon phase and date display. Like an open window watching the movement of the stars and their secrets through time, it attracts and fascinates. On the silver-coloured, sunray-brushed dial, the moon is set against a deep blue, starry background, with the dates printed in black around the moon phase aperture.

This timepiece benefits from an in-house movement designed, manufactured and assembled at Jaeger-LeCoultre’s Manufacture-Atelier in Le Sentier. Calibre 925 powers the Master Ultra Thin Moon. This self-winding movement is among the mainstays of the Maison’s collection, well proven over the course of many years and regularly updated in line with technical advances to improve reliability and precision. The latest versions of the calibre provide a power reserve of 70 hours. In full view through the transparent sapphire case-back, the movement features fine decorative finishes, including Côtes de Genève, bevelled bridges and blue screws. An open-worked 22K pink gold (916/1000) winding rotor enhances the visual appeal.

The new Ultra Thin Moon in 18K pink gold is an elegant and timeless 36mm dress watch, seamlessly uniting refined aesthetic proportions with high-performance in-house mechanical excellence.

• A champion shaped by versatility: a career built around the individual medley, perfecting the adaptability and discipline required to perform across four distinct strokes

• A refined sense of personal style: a sense of balance and considered simplicity that embodies contemporary ease and timeless elegance

• An intimate moment in The Hour Before: reflecting on the moments before competition, the experiences that have shaped the Olympic swimming champion and the mindset that drives his journey

Jaeger-LeCoultre reunites with Friend of the House and Olympic swimming champion Wang Shun for a new chapter of The Hour Before, the Maison’s interview series exploring the moments of preparation that precede defining moments. This episode brings together two worlds that share an intimate relationship with time, where precision is essential, movement is constantly refined and the smallest fraction of a second can make all the difference.

A CHAMPION SHAPED BY VERSATILITY

An individual medley is a discipline defined by change. Across a single race, the swimmer must move through four distinct strokes, each with its own rhythm, technique and physical demands. Success depends not only on mastering each one individually, but on understanding how to move seamlessly from one to the next. This constant need to adapt has shaped Wang Shun’s approach to swimming. Rather than relying on a single strength, he has developed an ability to find balance across different techniques, adjusting his rhythm and effort as the race unfolds. At the highest level, this versatility becomes instinctive. Years of training allow the body to respond naturally to change, while experience brings a deeper understanding of when to conserve, when to accelerate and how to maintain control across the entirety of a race.

It is this combination of versatility and control that distinguishes Wang Shun. His mastery lies not in repeating the same movement, but in moving confidently between different ones – preserving continuity while constantly adapting.

For Jaeger-LeCoultre, this ability to bring different forms of expertise together finds a natural resonance within the Manufacture-Atelier, where numerous specialised crafts coexist under one roof. Each has its own language and savoir-faire, yet all contribute to a single creation.

A DISTINCTIVE SENSE OF REFINED ELEGANCE

Wang Shun’s style carries the same quiet confidence that defines his approach to his sport. Contemporary yet considered, it is guided less by convention than by a natural sense of what feels authentic to him. He moves effortlessly between refined and more relaxed silhouettes, favouring a sense of balance and proportion over anything overly elaborate. This natural confidence finds a strong affinity with Jaeger-LeCoultre. The Maison has long approached elegance as an expression of character rather than display, creating timepieces whose refinement reveals itself through the purity of their design and the subtlety of their details. Deeply rooted in heritage yet continually reinterpreted, its creations transcend changing codes of style to become an expression of the wearer.

Wang Shun brings a similar sense of restraint to the way he dresses. His style reflects the discipline and focus that have shaped his journey as an athlete, while leaving room for individuality and personal expression. The Reverso embodies this spirit with particular clarity: an icon whose distinctive design has transcended generations while retaining an inherently personal character. For Wang Shun and
Jaeger-LeCoultre alike, true elegance is never about excess. It emerges naturally through balance, confidence and a considered sense of individuality.

THE HOUR BEFORE: WHERE CRAFTSMANSHIP REVEALS PERSONALITY

Jaeger-LeCoultre features Friend of the House and Olympic swimming champion Wang Shun in The Hour Before, an intimate interview format where he engages with the assembly of a Reverso case while reflecting on his journey. The conversation is guided by an off-camera interviewer and unfolds through a subtle rhythm that moves between the world of the Maison and Wang Shun’s personal experiences. The questions begin within the language of watchmaking before opening naturally onto his values, memories and perspective, creating a dialogue that feels reflective and grounded. Wang Shun reflects on the relationship between preparation and performance, as well as the experiences that have shaped his journey. The dialogue explores the discipline behind his achievements, the mental control required at the highest level of competition and his evolving relationship with time throughout his career.

More than an interview, The Hour Before is conceived as a moment of connection, where the precision of watchmaking gestures becomes a quiet entry point into personality. The conversation moves naturally between Wang Shun’s experiences in the water and the world of watchmaking, exploring a shared belief that mastery is built through patience, precision and perseverance. The rhythm and repetition of training find an echo in the gestures of the watchmaker, while the fractions of a second that can define a race reflect the constant pursuit of precision at the heart of mechanical watchmaking.

Shot in a natural and unforced manner, the episode captures Wang Shun with openness, focus and thoughtful sincerity, offering a rare glimpse into the person behind the Olympic swimming champion and the dedication that has shaped his journey.

Through this new chapter of The Hour Before, Jaeger-LeCoultre continues to engage with individuals whose distinctive paths to excellence reveal new perspectives on time, mastery and achievement.

• The shape of feminine watchmaking: a noble jewellery watch legacy harnessed to mechanical sophistication and aesthetic creativity with a unique bangle design

• Blending tradition and technology: classical jewellery codes combined with innovative and modern materials

• The mastery of miniaturisation: the world’s smallest rectangular manually wound mechanical movement, Calibre 101, showcases precision and technical expertise

Enriching the Calibre 101 series of High Jewellery watches with the new Calibre 101 Chain, Jaeger-LeCoultre reaffirms the unique alliance between High Jewellery and fine watchmaking made possible by this exceptional mechanism. The world’s smallest rectangular manual-winding mechanical calibre forms the centrepiece of a sculptural bangle of 18K pink gold (750/1000) set with diagonal bands of brilliant-cut white diamonds alternating with bands of deep, glossy black HyCeram® to create a boldly contemporary ode to femininity.

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 continuing 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 manual-winding calibre: At 14 mm long, 4.8mm wide and 3.4 mm thick (a volume of just 0.2 cm3), Calibre 101 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 – all 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 CHAIN: A BOLD EXPRESSION OF CONTEMPORARY FEMININITY

Where jewellery meets time: The tradition of jewellery watches began in the royal courts of 18^th- and 19^th-century Europe, when portable timepieces were rare and potent symbols of privilege and wealth. Embellished by goldsmiths, lapidaries, enamellers, and gem-setters, the arts of horology and jewellery became inextricably linked. By the early 20^th century, wristwatches were recognised as the most useful jewellery a woman could own. Harnessing the boundless creative possibilities of Calibre 101’s tiny dimensions, Jaeger-LeCoultre takes this legacy in a bold new direction with the Calibre 101 Chain. The new timepiece pays homage to a celebrated 1955 Duoplan model nicknamed ‘Chain’, which was designed with a braided chain bracelet of heavy, 18K pink gold (750/1000) polished links. The form of those links is echoed in the sculptural detail on the sides of the new Calibre 101 Chain bangle.

Inverting traditional watch design: The Maison’s Design department took a jewellery-led approach to creating this timepiece. Instead of starting with the case, they first designed the form of the bracelet, the style of the gem-setting, and the ornamentation – integrating the case and movement only at the very end. This beautifully inverts the traditional watch design process. The subject of more than 300 hours of technical research and development, Calibre 101 Chain is crafted according to classical High Jewellery codes, yet it allies these traditions with advanced materials technology in the form of HyCeram®– an intensely black, high-gloss ceramic composite.

Sculpting gold and advanced ceramics: The piece is created through the casting of 18K pink gold (750/1000), using a unique mould made specifically for each individual timepiece and recreated for every watch. Once cast, the surface is meticulously refined: the 36 existing HyCeram® cavities are carefully finished to ensure fine, immaculate edges, before the openings for the diamonds are precisely drilled. Liquid HyCeram® is then carefully injected into the cavities using a hand-held syringe. Once the material is perfectly flush with the pink gold, it is cured through a precisely calibrated process of pressure and heat, followed by meticulous polishing to reveal its rich depth of colour and mirror-like reflection.

A celebration of creative freedom: The bangle is then passed to a master gem-setter in Jaeger-LeCoultre’s Métiers Rares™ atelier to hand-set 158 brilliant-cut diamonds. Finally, the diminutive watch, with its black lacquer dial and diamond-set bezel, is integrated into the bangle. Showcasing Jaeger-LeCoultre’s mastery of miniature watchmaking and high jewellery, the new Calibre 101 Chain is a joyful celebration of the creative freedom allowed by the legendary Calibre 101.

THE COLLECTIBLES PROGRAMME

The Collectibles is Jaeger-LeCoultre’s in-house programme focused on 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 exclusive 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, each timepiece is ready to continue the story it began in the Vallée de Joux.

HONOURING THE PAST, INSPIRING THE FUTURE

Immersing visitors in the defining era of mid-20^th-century watchmaking, the first The Collectibles exhibition celebrates the Golden Age of mechanical watchmaking and the enduring appeal of its timepieces. The story unfolds in four chapters, exploring a different facet of this seminal period through emblematic timepieces from the Maison’s private Heritage Collection, all paired with contemporary models.

Duoplan: Introduced in 1925, the Duoplan reconciled extreme miniaturisation with chronometric precision, culminating in 1929 with Calibre 101, still the world’s smallest manually wound mechanical movement and the oldest calibre continuously produced by the Manufacture-Atelier.

Reverso: Created in 1931 for polo-playing British officers in India, Reverso’s patented swivelling case was designed to protect the dial during matches. Coloured dials, Staybrite stainless steel cases and a caseback made for personalisation established it as an icon of Art Deco design.

Memovox: Introduced in 1950, the Memovox integrated a mechanical alarm into a wristwatch calibre, establishing it as a signature complication of Jaeger-LeCoultre. Evolving from hand-wound models to the self-winding versions of 1957 and later calendar-equipped calibres, its distinctive dial and rotating alarm indicator make it instantly recognisable.

Precision: From the Triple Calendar of 1942 to the Geophysic, Geomatic and high-frequency Memovox Speed Beat GT, Jaeger-LeCoultre advanced the quest for precision with greater functionality, reliability, accuracy and chronometric excellence.

TEN MUSEUM-GRADE TIMEPIECES

The timepieces curated for Capsule VII demonstrate the depth and breadth of the Manufacture-Atelier’s technical and aesthetic innovation, from the 1920s to the dawn of the 21^st century. They also reflect the diversity of the 17 emblematic models in The Collectibles programme, each a high-water mark for Jaeger-LeCoultre and 20^th-century watchmaking.

Unveiled alongside the exhibition, the new Calibre 101 Chain combines jewellery elegance and miniature watchmaking. The world’s smallest rectangular manual-winding mechanical calibre forms the centrepiece of a sculptural bangle of 18K pink gold (750/1000) set with diagonal bands of brilliant-cut white diamonds alternating with bands of deep, glossy black Hyceram® to create a boldly contemporary ode to femininity. The exhibition includes the 1955 timepiece that was its direct inspiration.

The 1955 Duoplan Chain exemplifies a period when a timepiece could tr anscend its function to become an expression of style and refinement. Crafted from 73.92 grams of 18K pink gold (750/1000), its sinuous, polished links form an elegant bracelet, housing Calibre 403, the original Duoplan movement created for women’s watches. It bears heat-blued hands, created using a traditional watchmaking practice in which the colour of the hands is changed through a heating process.

Equipped with the same movement, the boldly graphic 1949 Duoplan Tubogas secret watch reflects Jaeger-LeCoultre’s creative diversity and the distinctive Tubogas style of 1940s jewellery design. Its ribbed 18K pink gold (750/1000) bracelet and dial cover contrast with the 18K yellow gold (750/1000) case, echoing the vertical lines of the cover, which conceals the dial until the wearer chooses to reveal it.

The single-lug Duoplan dating to circa 1935 is distinguished by its unusual strap attachment, with a single lug on each side of the case instead of the conventional two and a polished, rounded attachment bar. Blued hands provide a refined contrast against the harmonious combination of the copper-toned dial, the 18K pink gold (750/1000) case and custom-made light brown calfskin strap, finished with beige hand-stitching.

The circa 1950 Art Deco-style Calibre 101 watch sets the world’s smallest mechanical movement into a case just 6.15 mm wide and 5.84 mm thick. Its Platinum 950 case is set with 10 baguette-cut diamonds, accented by blue panels, while the two rings of the cordonnet bracelet hold 12 more, for a total of 22 baguette-cut diamonds.

With numerals replacing baton markers and subtle corner brackets replacing the original minutes track, the 1931 Reverso Cordonnet demonstrates the Reverso’s early adaptability to different wearers. This pioneering ladies’ model features a steel case fitted with Calibre T051, sourced from the highly reputable Tavannes for the first year of the Reverso’s life, allowing LeCoultre & Cie time to develop its own, shaped movements to fit the contours of the rectangular case. Reflecting the renewed enthusiasm for mechanical watchmaking in the 1990s, Jaeger-LeCoultre introduced a new generation of complicated Reverso calibres, housed in cases with sapphire crystal backs that revealed their mechanical complexity. As the 21^st century began, the Maison introduced two 950 Platinum models, each limited to 500 pieces.

The 2001 Reverso Platinum Number 1 features the Calibre 849R-SQ, specially adapted for the Reverso 42.2 mm case. Elevating the remarkably fine and lace-like effect of the skeletonisation, the bridges have been hand-engraved, as have both sides of the barrel, allowing a unique view of the mainspring. The blue of the sapphire set into the crown is echoed by the blued hands and the blue Cordovan strap, hand-crafted by Casa Fagliano, contrasting with the Platinum 950 case.

The 2003 Reverso Platinum Number 2 is an exercise in restrained, understated aesthetics. Its tone-on-tone grey dial features hand-painted numerals, while the power reserve is indicated by a hand mounted coaxially with the hours and minutes hands. The tourbillon reveals itself discreetly through the small seconds on the dial side, leaving the ‘fireworks’ for the reverse, where a mirror-polished bridge secures the spinning cage. Among the fine component finishes, the hand-bevelled tourbillon bridge is hollowed and black polished, recalling Jaeger-LeCoultre’s first tourbillon of 1946. Blued hands and a hand-crafted blue Cordovan strap by Casa Fagliano contrast with its Platinum 950 case and 18K white gold (950/1000) buckle.

Developed in 1942, the Triple Calendar (or Complete Calendar) calibre was one of the first complication watches produced in series. Used by Jaeger-LeCoultre in its own watches and supplied to other leading Maisons, it became one of the most emblematic complications of the mid-20^th century.

This 1949 example, in an 18K pink gold (750/1000) case with teardrop lugs, was customised for a Portuguese-speaking clientele, with the day and month discs marked in that language. A burgundy calfskin strap has been chosen to complement the warm tone of the gold.

The 1958 Futurematic E502 is the rarest reference among all Futurematic models. Nicknamed ‘Porthole’, it displays the power reserve and small seconds through two small windows. Launched in 1951 as the world’s “first entirely automatic wristwatch”, the Futurematic had a profound impact on the development of self-winding calibres. Designed to stop before it is fully unwound, the movement stores enough energy to ensure that, even after a prolonged period of immobility, it will restart with the slightest movement. A stop-seconds device ensures greater accuracy when resetting the time. The 37 mm steel case is fitted with a dark blue calfskin strap.

In 1958, the Memovox Parking was one of three new watches that Jaeger-LeCoultre launched to celebrate its 125^th anniversary. Designed to avoid parking tickets, the manually wound Calibre 814 enables the wearer to set the alarm 30, 60, 90 or 120 minutes in advance. With its robust steel case and highly practical complication, the watch embodies the function-driven watchmaking of the 1950s. The 35 mm case is fitted with a dark blue calfskin strap.

The 10 Collectibles timepieces will be available for purchase worldwide via jaeger-lecoultre.com from October 13, as well as at the Hong Kong flagship boutique during the presentation period. Each timepiece is offered with an extract from the Jaeger-LeCoultre archives and a complimentary copy of The Collectibles book.

• Expressing the Manufacture-Atelier’s core philosophy: a new quality seal of the Manufacture-Atelier Jaeger-LeCoultre to guarantee a high level of chronometric precision and high standards of watchmaking finishes, testimony of constant innovation while upholding the traditional values of fine watchmaking

• Precision of Chronometry: a new seal of quality, supported by an integrated, patented* testing protocol designed to simulate the stresses of real-world conditions

• Precision of Finishes: a qualitative guarantee of fine movement finishing and decoration

In keeping with its constant quest for precision and innovation, Jaeger-LeCoultre introduces its High Precision Guarantee (HPG) Seal, a new proprietary standard of watchmaking excellence. Applied to every single watch through an exhaustive testing and inspection process, the HPG Seal is certified by a quality seal on the caseback. It combines two fundamental dimensions of fine watchmaking: Precision of Chronometry, tested under conditions designed to simulate real-world wear and Precision of Finishes, guaranteeing that movement finishing and decoration meet the Manufacture-Atelier’s required standards.

Having debuted at Watches and Wonders 2026 with the Master Control Chronometre collection, Jaeger-LeCoultre’s HPG Seal embodies the Maison’s philosophy of constant innovation while upholding the traditional values and savoir-faire of fine watchmaking. The HPG Seal will be progressively extended across all Jaeger-LeCoultre collections.

CHAPTER 1: CONSTANT QUEST FOR TIMEKEEPING PRECISION: THE HISTORY OF HALLMARKS

The genesis of Maritime Precision: The quest for chronometric precision gained decisive momentum with the rise of global seaborne trade in the late 17^th century. Accurate measurement of longitude required clocks capable of maintaining exceptional precision at sea, leading to major advances in marine chronometry throughout the 18^th century and establishing the foundations of modern precision timekeeping.

Pioneering marine timekeeping: Among the pioneers was Edmond Jaeger, whose expertise in precision watchmaking was already well established by the late 1880s. In the early 1900s, his Torpedo Boat watches distinguished themselves in official timing competitions for their reliability and accuracy. His expertise later earned him the prestigious title of “Horloger de la Marine de l’État” - “Watchmaker to the State Navy”, reflecting his contribution to precision instruments for naval use.

International Recognition: In the late 19^th century, Antoine LeCoultre gained growing international recognition for his expertise in chronometric precision. His participation in major international exhibitions, notably in Paris and London, where his work was awarded medals, brought greater visibility to his achievements and helped establish his reputation on the international stage. These distinctions notably recognised the high degree of precision and quality of finishing achieved in mechanically produced calibres, demonstrating how technical performance could be combined with increasingly sophisticated manufacturing methods. As reflected in the medal table in the Maison’s Heritage Gallery, these awards contributed to establishing Jaeger-LeCoultre’s reputation for technical excellence and innovation in watchmaking.

Expanding fields of expertise: As advances in chronometry opened new possibilities, watchmakers were called upon to meet the requirements of increasingly demanding environments. The effects of gravity on timekeeping presented a fundamental technical challenge, inspiring increasingly sophisticated solutions. In the 1940s, aviation brought its own requirements, leading to the development of pilot’s watches designed for optimal legibility, robustness and reliable performance in demanding flight conditions. In 1948, Jaeger-LeCoultre launched the Pilot Mark XI, which would become one of the Maison’s most renowned aviation watches and an enduring expression of expertise in its field. Across land, sea and air, these evolving challenges continued to drive advances in watch design, functionality and chronometric performance.

Validated by Observatory Trials: As chronometric performance became an increasingly important measure of watchmaking excellence, observatory trials provided a rigorous framework in which Manufactures could demonstrate their expertise. Leading observatories in Geneva, Neuchâtel and Besançon subjected timepieces to rigorous trials, with Manufactures competing to demonstrate their chronometric expertise. In 1946, Jaeger-LeCoultre’s first tourbillon-equipped pocket watch, Calibre 170, won the prestigious Neuchâtel Observatory chronometry competition.

By the end of the 1960s, the rise of quartz technology transformed the watchmaking landscape and traditional observatory competitions gradually lost their central role. A new framework for certifying mechanical precision emerged with the creation in 1973 of the Contrôle Officiel Suisse des Chronomètres (COSC), which established an independent benchmark for Swiss chronometer certification.

Safeguarding the Geneva legacy: Alongside chronometric certification, hallmarks have long served to guarantee provenance, quality and workmanship. Geneva established the world’s first watchmakers’ guild, the Maîtrise des Horlogers de Genève, in 1601, and in 1886 the Grand Council of Geneva introduced the Poinçon de Genève (Geneva Seal) to protect the reputation and standards associated with Geneva watchmaking. Over time, this tradition of independent certification also inspired leading Manufactures to develop their own proprietary standards and seals. In 1992, this pursuit led to the creation of the 1,000 Hours Control, a demanding in-house testing protocol designed to assess the performance and reliability of the fully assembled Jaeger-LeCoultre watches.

CHAPTER 2: THE MANUFACTURE-ATELIER, MASTERING PRECISION AT EVERY STEP

Mastering excellence at every step: At the Manufacture-Atelier, mastery extends across every stage of watchmaking - from the production of each component to the final assembly and finishing of every timepiece. Throughout manufacturing, including the machining of even the smallest parts, rigorous quality controls guarantee uncompromising precision. Yet Jaeger-LeCoultre’s ambition has always gone beyond mastering production alone: the goal is to create watches that are not only impeccably crafted, but also among the most precise and reliable in everyday wear.

A pioneering vision of precision: Since 1833, Jaeger-LeCoultre has pursued precision as a defining principle of its watchmaking. The invention of the Millionomètre in 1844, the first instrument capable of measuring the micron, enabled ever greater accuracy in the creation of components and increasingly sophisticated calibres.

This mastery naturally extended to chronometric performance, finding expression in wristwatches such as the Futurematic and Geophysic in the 1950s. In 1970, the Polaris II gave this longstanding pursuit a name: “High Precision Guarantee”, displayed on its dial as a signature of its innovative 4Hz calibre.

In 1992, the launch of the Master Control marked a significant milestone with the introduction of the 1,000 Hours Control. This rigorous testing protocol was designed to assess the performance, reliability and quality of each fully assembled watch, setting a new benchmark for precision and excellence.

A new level of high precision: More than five decades after the “High Precision Guarantee” designation first appeared, Jaeger-LeCoultre brings this historic name into a new era with the HPG Seal. Drawing on the Manufacture-Atelier’s mastery of every stage of creation and decades of expertise in testing and chronometric performance, it introduces a new proprietary standard for Jaeger-LeCoultre timepieces.

Its rigorous certification process combines multiple tests performed through an innovative, integrated protocol, validating the precision, reliability and quality of each timepiece. At the same time, the HPG Seal guarantees the exacting standards of movement finishing that are inseparable from Jaeger-LeCoultre’s vision of Haute Horlogerie.

By bringing together integrated manufacturing expertise, rigorous testing and exceptional finishing, the HPG Seal represents the latest expression of Jaeger-LeCoultre’s constant pursuit of precision and excellence. Every HPG-certified timepiece undergoes the complete testing protocol, ensuring that each individual watch meets Jaeger-LeCoultre’s exacting standards.

CHAPTER 3: A NEW SEAL OF PRECISION, QUALITY AND RELIABILITY

Simulating extreme wear: Evaluating real-world timekeeping performance, the new HPG Seal tests timepieces under four critical conditions. The first test is performed on the calibre alone, while the remaining three are conducted on the fully cased watch:

• Altitude*: Simulates atmospheric pressure variations from sea level to 1,004 meters (the elevation of Jaeger-LeCoultre’s Manufacture-Atelier in Le Sentier).

• Multi-directional Shocks: Applies impacts ranging from 25G to 50G across multiple standardised positions.

• Positions: Alternates periods of multi-position motion and fixed resting positions.

• Temperature: Replicates fluctuations from 18°C (simulating rest) to 35°C (simulating active physical movement).

*Performed on the calibre alone

The Patented* Dynamic Protocol: Rather than assessing these parameters in isolation, a custom-developed HPG machine subjects each timepiece to alternating cycles where various stresses are applied simultaneously. Two days of dynamic wear cycles replicate the movements of active weekdays, combining fixed positions, multi-position motion, shocks and temperature changes. On the third day, the timepiece enters a "stabilized rest" cycle in a fixed position, mimicking a watch resting over the weekend. This integrated, patented* protocol ensures the watch maintains chronometric accuracy throughout the full spectrum of a wearer's life, far beyond ideal laboratory conditions.

Beauty, beyond precision: Beyond precision and durability, the High Precision Guarantee (HPG) Seal recognises an exceptional standard of movement finishing – an art that originally served to reduce friction and glare but evolved in the 18^th and 19^th centuries into a beautiful play of light. For Jaeger-LeCoultre, fine finishing is inseparable from precision: it must be executed to micron-perfect accuracy to enhance movement performance while highlighting the beauty of the mechanism. To qualify for the High Precision Guarantee (HPG) Seal, a watch must incorporate at least six of these eight traditional finishing techniques:

• Bevelling: Shaving and polishing the 90-degree edges of components to a mirror-like shine.

• Burnishing: Compressing and polishing metal components, particularly pivots, to enhance durability and surface hardness.

• Circular smoothing: Using fine abrasives to create a smooth, matte circular texture.

• Linear Smoothing: Using fine abrasives to draw uniform, parallel matte lines along flat surfaces.

• Counter-sinking Jewels: Creating polished, chamfered recesses around jewel holes in plates or bridges to ensure a perfect fit and help retain lubrication.

• Côtes de Genève: Applying parallel wave-like patterns to large components to diffuse light and trap microscopic dust.

• Perlage (Circular Graining): Placing overlapping circular patterns on plates and bridges to diffuse reflections.

• Polished Screw-heads: Polishing the head of every screw to create a perfectly flat, reflective surface.

CHAPTER 4: A NEW CHAPTER FOR HIGH PRECISION GUARANTEE

Having introduced the High Precision Guarantee (HPG) Seal with the Master Control Chronometre collection at Watches & Wonders Geneva in April 2026, Jaeger-LeCoultre will gradually expand the certification across its collections, beginning in 2027. For its debut with the Master Control Chronometre collection, each calibre was first COSC-certified before undergoing Jaeger-LeCoultre’s more comprehensive HPG testing protocol, further raising the standards of precision, quality and reliability.

With its dual focus on timekeeping precision and refined decorative artistry, the High Precision Guarantee Seal encapsulates Jaeger-LeCoultre’s commitment to the values of traditional Haute Horlogerie, while continuously innovating and evolving its collections.

• Time, kept secretly: inspired by a heritage of secret watches, where horological ingenuity meets the art of discreetly concealing time

• Exceptional gem-setting savoir-faire: 124 brilliant-cut pink sapphires and 904 brilliant-cut diamonds represent 163 hours of gem-setting work

• The mastery of miniaturisation: the world’s smallest rectangular manually wound mechanical movement, Calibre 101 showcases precision and technical expertise

Enriching the Calibre 101 series of High Jewellery watches with a dazzling new version of 101 Secrets, Jaeger-LeCoultre reaffirms the unique alliance between High Jewellery and fine watchmaking made possible by this exceptional mechanism. The world’s smallest rectangular manual-winding mechanical movement is paired with pink sapphires, graduated in shades from vivid cyclamen to pale blush, diamonds and 18k Pink Gold (750/1000) – a new interpretation of 101 Secrets that will be produced in a limited edition of three pieces.

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.

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).

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.

• Partnering with a distinctive force in modern cinema

• Robert Pattinson joins Jaeger-LeCoultre as Global Ambassador

• A shared commitment to creativity, modernity and enduring craftsmanship

Jaeger-LeCoultre is pleased to announce the appointment of British actor Robert Pattinson as its newest Global Ambassador. This exciting partnership brings together the Manufacture’s pursuit of precision and timeless design with Robert Pattinson’s singular talent, artistic audacity and effortless elegance.

As a genuine admirer of fine watchmaking and the artistry behind mechanical timepieces, Robert Pattinson reflects: “For me, the most compelling objects are the ones that have real depth to them. A great watch isn’t just about precision – it’s about character, craftsmanship, and the story behind how it’s made. 
Jaeger-LeCoultre has always embodied that kind of quiet mastery. There’s an integrity to everything they create, where technical innovation and artistic expression exist in perfect balance. I find that approach incredibly inspiring, and it’s something I deeply connect with in my own work.”

A DISTINCTIVE FORCE IN MODERN CINEMA

Robert Pattinson has built one of the most singular careers in cinema, shaped by bold artistic choices and a refusal to be confined by expectation. A career defined less by predictability than by constant reinvention. Moving between auteur cinema and major international productions, he has followed a path defined by freedom, instinct and a deeply nuanced approach to performance. Drawn to roles that challenge convention, he brings to each character a sense of depth, mystery and emotional tension, revealing complexity through restraint rather than excess. This instinct for transformation echoes Jaeger-LeCoultre’s own creative vision, rooted in almost two centuries of savoir-faire while constantly reinventing itself through pioneering innovation and technical mastery. An approach where precision is never static, but constantly redefined.

EMBODYING CONTEMPORARY ELEGANCE

Robert Pattinson embodies a refined sophistication that is instinctive, personal and never overstated. Both on and off screen, his presence reflects a rare balance of individuality and quiet confidence.

His sense of style follows the same quiet precision. Expressed through subtle contrasts, refined proportions and an ease that feels entirely his own, it reflects a sophistication free from excess. In this balance between classic codes and unexpected details, Robert Pattinson gives elegance a distinctly personal character. This creative freedom and bold sense of self resonate naturally with Jaeger-LeCoultre’s aesthetic values, where refinement is expressed through subtlety and lasting distinction.

A PATH DEFINED BY CHARACTER

Beyond his achievements on screen, Robert Pattinson is defined by the values that have shaped his journey. Guided by curiosity, authenticity and an unwavering commitment to excellence, he has built a career on thoughtful choices rather than convention. His independent spirit is matched by a quiet discipline, approaching each new challenge with the same desire to refine and push beyond what has come before. It is this pursuit of lasting substance over immediate recognition that gives his work its singular character.

These values resonate deeply with Jaeger-LeCoultre. Since its founding, the Maison has pursued excellence not as an end but as a continuous process of refinement, where technical mastery, innovation and craftsmanship exist in constant dialogue. Rooted in authenticity and driven by an enduring spirit of curiosity, it has continually evolved while remaining faithful to its identity. This shared belief that true excellence is achieved through integrity, dedication and the relentless pursuit of progress forms the foundation of a partnership defined by character as much as creativity.

“Robert Pattinson represents a rare combination of artistic depth, curiosity, and authenticity,” says Jérôme Lambert, the CEO of Jaeger-LeCoultre. “His journey is defined by a relentless commitment to excellence and an independent spirit that aligns seamlessly with the values of our Maison. 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.

• Craft continuity: Preserving ancestral craftsmanship and ensuring its transmission to future generations

• Homo Faber Fellowship co-creations: introducing objects developed during the two last editions of Homo Faber Fellowship in partnership with Jaeger-LeCoultre

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.

• Homage to La Serenissima: the beauty and shimmering light of Venice, as captured by J.M.W. Turner, one of the greatest landscape painters in Western art history

• Showcasing the Métiers Rares™: uniting the crafts of miniature painting, enamelling, paillonage and hand-guillochage

• Intricate enamelling: a complex process requiring 14 layers of enamel to recreate the sense of depth and perspective, the limpid light and the floating effect of the clouds

• An exclusive production: four Reverso Tribute Enamel timepieces, each issued in a limited edition of only 10 pieces each

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.

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.

OPENING HOURS AND ADMISSION

‘The Valley of Inventions’ will take place from 10 September until 23 September 2026 at Zhangyuan W4, Lane 188, Maoming North Road, Jing'an District, Shanghai. It is open to the public every 11.00AM until 08.00PM every day. Visitors may register online in advance at WeChat mini program link or on arrival.

• Jewellery as a timekeeping art: the Rendez-Vous Jewellery Night & Day masterfully fuses miniature hand-painting, precision gem-setting, and the poetic Night & Day complication; adorned with 48 baguette-cut diamonds, it epitomizes Jaeger-LeCoultre’s unparalleled mastery in feminine watchmaking

• Contemporary elegance: the Rendez-Vous Hour-Minute reimagines the collection’s signature codes with a refined aesthetic tailored for modern femininity; at a mere 7.47mm, one of the slimmest timepieces in the Rendez-Vous collection

• Exceptional craftsmanship: a showcase for Jaeger-LeCoultre’s Métiers Rares™ expertise, the collection highlights unique mastery through intricate decoration and meticulous hand-finishing

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). Powered by the automatic Calibre K883S, chronometer-certified and tested for 360 hours, it features a stop-seconds mechanism for precise time-setting and an instantaneous jumping date. This highly technical construction reflects the pursuit of accuracy at the heart of the Geomatic line. It is fitted on a hand-crafted taupe calfskin leather strap.

Each timepiece offered under The Collectibles programme is presented with an extract from the Jaeger-LeCoultre archives and a complimentary copy of The Collectibles book, as well as a new handmade leather strap chosen to complement the style of each watch, except in cases where the model has a metal bracelet. In addition, when available, the original box and papers together with the original strap or bracelet will be included.

LONDON TO HOST THE PRESENTATION OF THE SIXTH CAPSULE OF THE COLLECTIBLES

The sixth capsule of The Collectibles will be unveiled on June 15 at Jaeger-LeCoultre’s London flagship, at 13 Old Bond Street, London W1 and will remain on display to the public until July 18. The opening hours are from 10:00 to 18:00, Monday to Saturday.

The Collectibles book will also be available via jaeger-lecoultre.com and at all Jaeger-LeCoultre boutiques.

• Where discipline in performance meets the precision of fine watchmaking

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

• A shared commitment to craft, collaboration and quiet excellence

Jaeger-LeCoultre is delighted to announce internationally acclaimed artist and member of K-pop icon SEVENTEEN, JOSHUA, as Friend of the House. Revealed through the Maison’s interview series The Hour Before, the collaboration reflects a shared appreciation for artistry, precision and dedication to craft.

A JOURNEY SHAPED BY DISCIPLINE, COLLABORATION AND CONSISTENT CRAFT

As a member of SEVENTEEN, JOSHUA has grown within one of the most dynamic and closely self-produced groups in global music, where every performance is shaped through collaboration and constant refinement. Known for his calm presence and natural sense of balance within the group, he approaches his craft with quiet determination.

From his early training years in South Korea to performing on stages around the world, JOSHUA’s journey has been defined by an ongoing pursuit of improvement. Driven by a dedication to his craft, he has built his artistic identity through commitment, teamwork and attention to detail – values that resonate strongly with Jaeger-LeCoultre.

Within the Manufacture, excellence is achieved through time, precision and the mastery of countless carefully considered gestures. Every component, adjustment and finishing detail reflects discipline and respect for craft. In this way, JOSHUA’s artistic journey mirrors the Maison’s own philosophy: a belief that true mastery is built gradually, through dedication and consistency over time.

A PRESENCE DEFINED BY BALANCE, EASE AND UNDERSTATED ELEGANCE

JOSHUA’s style is defined by simplicity and an understated elegance that feels both modern and timeless. His artistic evolution is based on continuous refinement – a natural strengthening of identity shaped through experience.

Whether on stage or in more personal moments, he brings a sense of ease and authenticity that feels intrinsic. His quiet confidence and measured approach to style reflect a contemporary elegance rooted in sincerity and balance.

This sensibility aligns naturally with Jaeger-LeCoultre’s creative philosophy. For the Maison, refinement is never about excess, but about proportion, precision and thoughtful design. Like the Reverso – an icon defined by clean lines – JOSHUA’s presence is distinguished by subtle versatility.

THE HOUR BEFORE: WHERE CRAFTSMANSHIP REVEALS PERSONALITY

Jaeger-LeCoultre introduces JOSHUA’s collaboration through The Hour Before, an intimate interview format where he engages with the assembly of a Reverso case while reflecting on his journey. The conversation is guided by an off-camera interviewer and unfolds through a subtle rhythm that moves between the world of the Maison and JOSHUA’s personal experiences. The questions begin within the language of watchmaking before opening naturally onto his values, memories and perspective, creating a dialogue that feels reflective and grounded.

More than an interview, The Hour Before is conceived as a moment of connection, where the precision of watchmaking gestures becomes a quiet entry point into personality. The format reveals parallels between horological craft and artistic life: discipline, repetition, teamwork and the pursuit of progress over time.

Shot in a natural and unforced manner, the episode captures JOSHUA with sincerity and ease, offering a rare glimpse into the thoughtful presence beyond the spotlight.

“We are delighted to welcome JOSHUA to the Jaeger-LeCoultre family,” says Jérôme Lambert, CEO of Jaeger-LeCoultre. “His sincerity, his discipline and his commitment to his craft resonate with the values of our Maison. Through The Hour Before, we are pleased to highlight the quiet dedication that connects his artistic journey with our own approach to watchmaking.”

This collaboration reflects Jaeger-LeCoultre’s continued engagement with individuals who embody authenticity, balance and a deep respect for craft.

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 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.

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 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.

• 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.
