The remarkable Master Ultra Thin line enriches its collection with three new models featuring complications among the most emblematic of watchmaking expertise – moon phases, tourbillon, date, and perpetual calendar. A testament to precision and sophistication, these three new limited editions in white gold and midnight blue enamel complement the Master collection.

Master Ultra Thin Tourbillon Enamel

The new Master Ultra Thin Tourbillon Enamel features a new tourbillon movement and a new-look date counter. They form a balanced pair on this watch, produced in a limited series of 50 pieces. In an elegant case from the Master Ultra Thin collection, the famous Jaeger-LeCoultre Caliber 978 has been reconceived both technically and aesthetically. In terms of finishes, the sunray-effect really stands out, as does the light and graceful gold oscillating weight. As always, one’s gaze is captured by the endlessly fascinating spectacle of the tourbillon, fittingly placed in an aperture at six o’clock.

A Jaeger-LeCoultre tourbillon

The Master Ultra Thin Tourbillon Enamel gives us a glimpse of the watchmaking expertise of the Manufacture. With an almost tangible quality under its transparent sapphire crystal, the tourbillon showcases its acrobatic dexterity with rare precision on a blue and white gold backdrop, revealing the details of its exceptional finishes. In an eternal dance, Jaeger-LeCoultre's emblematic tourbillon marks out the time in a way that is both precise and precious.

Sophisticated details

With the Master Ultra Thin Tourbillon Enamel, fine watchmaking has taken a step forward in terms of refinement. The arrow of the small seconds hand indicates 60 numerals as it makes its way around the dial, a true demonstration of excellence. For the artists and artisans of the Manufacture's Rare Handcrafts (“Métiers Rares®”), the Master Ultra Thin line remains an endless source of inspiration. This new model will win over anyone who loves precision, as every detail is heightened in a pure expression of sophistication. Like the hand-guilloché dial that blends in with a beautiful blue enamel background. Or the perfectly proportioned white gold case, with its 40 mm diameter. Or the slender hour markers, specially redesigned for this limited edition, like a natural extension of timeless and understated Dauphine hands.

Jaeger-LeCoultre’s Master Ultra Thin Tourbillon Enamel is a perfect example of the exceptional expertise of the Manufacture in the Vallée de Joux. In terms of both function and form, the watch is characterized by the attention paid to every last detail, with the extreme precision of its movement complementing the extreme precision of its design.

Master Ultra Thin Perpetual Enamel

With its four internal apertures that are the embodiment of watchmaking complications and a blue enamel guilloché motif, the new Master Ultra Thin Perpetual Enamel asserts itself from the very first gaze. This ultra-thin piece has seen a reimagining of its famous Jaeger-LeCoultre Caliber 868, one of the most emblematic of the Grande Maison. Both inside and outside its case, this new interpretation has all the hallmarks of exclusivity, as can be seen by the number of pieces produced: only 100 for this limited edition.

A new perpetual calendar

The new and original display of its perpetual calendar (day at 3 o’clock, date at 9 o’clock, month and year at 12 o’clock) simultaneously indicates the moon in both the Northern and Southern hemispheres. In a starry sky that has been delicately polished, the moon phase is housed in a disk at 6 o’clock. Enhanced by a new design, including an engraved counter that immediately attracts the eyes, it sets itself in motion thanks to its different phases, waxing or waning. A perfect example of the mastery of Rare Handcrafts (“Métiers Rares®”), this symbolic complication provides the Master Ultra Thin Perpetual Enamel with an aura that connoisseurs are sure to appreciate.

Specially developed hour-markers for this limited edition

Just like the two limited editions from the same family, the Master Ultra Thin Perpetual Enamel watch sets itself apart with its refined and lengthened hour-markers. Their stretched-out silhouette elegantly blends in with the guilloché blue enamel dial. Completed by hand at the Jaeger-LeCoultre Manufacture, this artistic work enhances the functions on this model, where a concern for ergonomics is visible to the naked eye. The intense and luminous blue of the new and perfectly geometrical guilloché dial goes well with the deep blue of the matching alligator strap.

The Master Ultra Thin Perpetual Enamel watch not only showcases the precision of its movement and complications, but also, and essentially, artisanal handcrafts. With the help of ancestral tools, some of which were produced on site at the Grande Maison, artisans use their hands to enamel, polish, refine, enhance and carry out guilloché work on dials, movements and complications, in accordance with age-old processes, solidifying Jaeger-LeCoultre's reputation as an essential watchmaking Manufacture. Since 1833, the art of precision so dear to Antoine LeCoultre has well and truly expanded beyond the borders of the Vallée de Joux and the Jura mountains in Switzerland.

Master Ultra Thin Moon Enamel

Issued in a limited series of 100 pieces, the new Master Ultra Thin Moon Enamel proudly expresses its character in a pure and refined watchmaking style, which translates directly into a new hand-guilloché blue enamel dial, new hour-markers, a new polished moon, and a new engraved counter. Its extremely thin case in white gold (10.04 mm) conceals its engine, the Jaeger-LeCoultre Caliber 925, an automatic mechanical movement with a 70-hour power reserve.

A hand-guilloché blue enamel dial

The elegance of the new Master Ultra Thin Moon Enamel comes down to the assertive character of its guilloché blue enamel dial. This deep captivating blue brings to light the geometric motifs and the relief effect characteristic of guillochage, a traditional decorative technique more fashionable than ever. Enameling, this age-old expertise, was reinstated at the Manufacture in 1996. Executed completely by hand by a few artisans trained at the Manufacture, enameling requires extreme concentration and infinite patience. Furthermore, performing the guillochage work and the application of the translucent blue enamel layer requires an incomparable level of meticulous attention.

A new polished moon phase

The Master Ultra Thin Moon Enamel features a new moon phase setting, one that has been redesigned with painstaking attention to detail. When the moon is full, its perfectly round and polished white disk comes to rest on an exquisite stellar background.

A new take on hour-markers and an engraved counter

In addition to the unmistakable presence of the polished moon phase, this limited edition of 100 pieces skillfully revisits the standards of the Master Ultra Thin, a line that has been a watchmaking classic for over 20 years. Connoisseurs are sure to notice the new design of the hour-markers, which are longer and split into two at 12, 3, 6 and 9 o’clock. In an aperture at 6 o’clock, the counter that houses the polished moon phase has been engraved, a way of bringing out the numerals depicting the date. Visually, the effect is one that combines presence and discretion.

An emblematic piece that showcases the expertise of the Jaeger-LeCoultre master watchmakers, artists and artisans, who have ceaselessly reinvented mechanical precision, all while combining it with peerless artistic creativity.

Jaeger-LeCoultre’s history is rooted in the Vallée de Joux, bordering the Swiss Jura Mountains. Beyond the peaceful image it conveys, this setting forged the very identity of the Manufacture. Against this backdrop where patience and calm are intrinsic to the landscape, there grew up a tradition of precision bound up with a profoundly authentic artistic élan.

A balance of technical sophistication and perfected skill

For Jaeger-LeCoultre, the quintessence of the watchmaker’s art lies in achieving a perfect balance between precision techniques and the deft craftsmanship required to perform them. From the invention of the Millionomètre to the Gyrotourbillon, this balance is expressed in the diversity of the Manufacture's Rare Handcrafts (“Métiers Rares®”) and the many-faceted expertise of its master watchmakers, united in a common pursuit: to match technical sophistication with esthetic finesse.

Craftsmanship and precision

The Manufacture set itself two objectives from the outset: accuracy of the movement, and technical precision. These goals both emerged from, and flourished in, this Swiss natural setting, whose calm and serenity seem to abide, undisturbed, from one season to the next. The Manufacture's master watchmakers are deeply influenced and inspired by this environment, throwing their heart and soul into every ingenious sketch, every oscillation of the balance wheel, every escapement wheel—always pushing the boundaries of precision.

An endless wellspring of inspiration

From its caliber to its case, every Jaeger-LeCoultre watch is entirely designed, manufactured and assembled under one roof. This is why the name Jaeger-LeCoultre is so closely associated with some very revealing figures. Almost 180 specialist skills and trades are assembled in our manufacture, along with nearly 1,250 calibers from the simplest to the most sophisticated and some 400 patents.

The quest for precision is also reflected in milestones of invention, all of them world firsts, from the first tools to cut the pinions invented by Antoine LeCoultre who was determinate to reach excellence. Then Millionomètre in 1844. First grande complication pocket watch in 1895. Chronomètre Geophysic in 1958. Jaeger-LeCoultre Caliber 920 in 1967. Master Control 1000 Hours in 1992. Gyrotourbillon 1 in 2004. Duomètre and Dual Wing concept in 2007. Grand Prix de Chronométrie in 2009 … This list is far from exhaustive, and is constantly expanding with new precision inventions that mark out the Manufacture as the irrefutable gold standard, both nationally and worldwide. At Manufacture Jaeger-LeCoultre, pursuit of excellence, attention to infinitely small details, and patience are necessary at every single stage of designing, making and finishing/completing each watch and clock.

When precision becomes art

Jaeger-LeCoultre has made precision an art form in its own right: because technical and mechanical precision are matched by the precision and artistry of the workmanship. Age-old skills like guillochage, engraving, gem-setting, and enameling are still at the heart of the expertise preserved in the Maison and its Rare Handcrafts (“Métiers Rares®”).

As the name “Manufacture” suggests, the hand of man is indeed at the helm here. It is man who dreams up and designs the prototypes. It is the hand of man that directs and breathes life into the tools and instruments, the movement and its heartbeat, the materials and the precious stones. These hands belong to craftsmen who never cease to hone their skills—that is, to ensure that their tiniest gestures are as careful, as rigorous, as fitting, and as precise as possible. Even if it means going higher than where the bar is usually set.

The guilloché enamel exteriors of this new Master Ultra Thin Enamel model is a testament to precision and sophistication, where blue is featured in all its majesty – a deep, intense midnight blue which achieves perfect harmony with the case of this limited edition.

Master Ultra Thin Moon Enamel

Issued in a limited series of 100 pieces, the new Master Ultra Thin Moon Enamel proudly expresses its character in a pure and refined watchmaking style, which translates directly into a new hand-guilloché blue enamel dial, new hour-markers, a new polished moon, and a new engraved counter.
