Exploring the full potential of the Reverso as a canvas for artistic expression, Jaeger-LeCoultre introduced the Reverso Hybris Artistica Calibre 179 in 2023—an exceptional timepiece that united the highest watchmaking expertise with intricate and sophisticated artistic decoration. Marrying La Grande Maison’s signature multi-axis tourbillon to the finest decorative craftsmanship, this creation exemplified the philosophy of the Hybris collection. In 2025, the Maison reinterprets the Reverso Hybris Artistica Calibre 179 in 18k white gold (750/1000), to be produced in a limited edition of 10 pieces.

A TOUR-DE-FORCE OF MECHANICAL INGENUITY INSPIRED BY A FASCINATION WITH THE TOURBILLON

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. The 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 (historical patent CH159982) and distinctive Art Deco lines have remained constant, making the Reverso one of the world’s most recognisable wristwatches.

The Reverso was born as a deft synthesis of style and function. Rooted in the Art Deco aesthetics, it also embodied a mechanical revolution allowed by La Grande Maison’s expertise. From the very beginning of its production, Reverso’s calibres were shaped to follow the curves of its rectangular case, an ingenious answer to maximise space used and therefore the precision of the calibre. In 1931, it was seen as a revolution in Haute Horlogerie: an unusual rectangular case, powered by shaped calibres, set in a dedicated casing ring to protect them from shocks, humidity and the passing of time.

This technical challenge, overtook by the Manufacture, was fully embraced in the beginning of the 1990s, when Jaeger-LeCoultre introduced high complications in Reverso. Calibre 179 features the fourth evolution of the Gyrotourbillon, the Manufacture’s signature multi-axis tourbillon (historical patent CH694598A5) – a technical tour-de-force developed specifically for the 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, Calibre 179 is a Duoface movement (historical patent EP0633514), displaying a different time zone on each dial as well as a 24-hour indicator for the second time zone on the reverse dial.

Visually enthralling to observe as it pirouettes around its twin axes, the structure of the Gyrotourbillon is highly complex: with a total of 123 components, it comprises 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 rotates 360 degrees every 16 seconds and the peripheral carriage makes a full rotation once per minute; this peripheral carriage also provides a small seconds function, indicating the seconds 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 pursuit of 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 add aesthetic refinement as well as being highly efficient. 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. As a result, this flying Gyrotourbillon appears to be floating in the space between the front and back dials of the Reverso, with no apparent means of support. 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.

A NEW COLOUR PALETTE SHOWCASES THE SKILLS OF THE MANUFACTURE’S CRAFTSMEN

Anchoring the colour palette of the Reverso Hybris Artistica Calibre 179 and creating a rich contrast with the solid white gold case, bridges and decorative plates, shiny dark blue lacquer also decorates the front and reverse dials of the watch.

With its double-sided, Duoface movement, this Reverso offers two distinct personalities. On the front dial, in a subtle allusion to the geometric patterns of Art Deco that determined the original Reverso design, a lattice of fine lines matches the colour of the precious metal case. The cool, silvery tones of the white gold contrast with the blue lacquer of the decorative plates and bridges, complementing the deep blue gradient lacquer of the front dial.

These lines are in fact ultra-fine ribs of the calibre plate metal, which remained when the surface was hollowed out to create depressions to contain the lacquer. A work of extraordinary precision, the lacquer was deftly hand-applied between the metal ribs to achieve the desired richness of colour and exactly the right depth; the surface is then polished by hand by the same craftsman to a glossy finish that is perfectly flush with the ribs.

On the reverse dial, blue lacquer has been applied to the fine tracery of the skeletonised hours-minutes ring and its supporting bridges, highlighting the airy aesthetic and contrasting with the warm tones of various movement components and the soft texture of the micro-blasting. The decoration on the reverse dial is a fascinating marriage of technology and tradition, with laser skeletonisation complemented by hand chamfering and hand-applied lacquer – affirming Jaeger-LeCoultre’s deep commitment to tradition while constantly seeking innovative approaches to the art and science of horology. Representing approximately 14 hours of chamfering 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 La Grande Maison’s commitment to hand-craftsmanship of the highest order.

A PERFECT EXPRESSION OF ART DECO DESIGN 
CREATES A TIMELESS ICON

Instantly recognisable, the rectilinear geometry and harmonious proportions of the Reverso case belie the complexity of a design that incorporates the signature slide-and-swivel mechanism. The inside of the cradle is decorated with a deeply engraved sunray pattern that radiates out from a blue lacquer disc. The strong Art Deco lines, emphasised by the signature gadroons above and below the dial, provide a perfect foil for the intricate decoration of the two dials of the Reverso Hybris Artistica Calibre 179.

Comprising 382 components, including the intricate Gyrotourbillon, the Reverso Hybris Artistica Calibre 179 embodies exceptional complexity. Yet, with an overall thickness of just 13.63mm and refined lugs, it remains both elegant and effortlessly comfortable – a testament to the ingenuity of our engineers in achieving such a harmonious balance of sophistication and wearability.

Crafted entirely in white gold (18k, 750/1000) and weighing nearly 30 grams, the adjustable folding buckle of the Reverso Hybris Artistica Calibre 179 epitomises both technical innovation and refined elegance. Comprising 46 meticulously assembled components, this intricate mechanism incorporates a double-wheel system that allows for micro-adjustments to the nearest 0.5mm, ensuring a perfectly tailored fit. Designed to complement the exceptional artistry of the timepiece, the buckle combines ergonomic sophistication with the timeless allure of precious metal, reflecting Jaeger-LeCoultre’s dedication to both precision and comfort.

Jaeger-LeCoultre – REVERSO Tribute Geographic Edition

Jaeger-LeCoultre – REVERSO® Tribute Geographic Calibre 826 Gold Edition 2025

TWO NEW TIMEPIECES THAT REINTERPRET A CLASSIC COMPLICATION

 KEY FACTS:

New in-house Calibre 834: offering a 42-hour power reserve and comprising 209 components
Watchmaking excellence: integrating two notable complications – the World Time and the Grande Date, with a patented design of the date discs
Refined craftsmanship: a map disc laser cut with 141 hollows hand-filled with lacquer

Jaeger-LeCoultre introduces the Reverso Tribute Geographic, powered by a newly developed in-house movement, Calibre 834. A fresh interpretation of the quintessential travel time complication, displaying the world time indication on the reverse dial, it is presented in a steel case or an 18k pink gold (750/1000) case, the latter in a limited edition of 150 pieces. The new timepiece underlines the role that the Reverso has played as a catalyst for innovation over nine decades, ever since its unique swivelling case was invented in 1931.

FROM SPORTS WATCH TO HIGH COMPLICATIONS – INNOVATION CONTINUES

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. The 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 (historical patent CH159982) and distinctive Art Deco lines have remained constant, making the Reverso one of the world’s most recognisable wristwatches.

The Reverso was born as a deft synthesis of style and function. Rooted in the Art Deco aesthetics, it also embodied a mechanical revolution allowed by La Grande Maison’s expertise. From the very beginning of its production, Reverso’s calibres were shaped to follow the curves of its rectangular case, an ingenious answer to maximise space used and therefore the precision of the calibre. In 1931, it was seen as a revolution in Haute Horlogerie: an unusual rectangular case, powered by shaped calibres, set in a dedicated casing ring to protect them from shocks, humidity and the passing of time.

This technical challenge, overtook by the Manufacture, was fully embraced in the beginning of the 1990s, when Jaeger-LeCoultre introduced high complications in Reverso. Beginning in 1991, underlining its commitment to both technical and aesthetic innovation, the Manufacture developed six new Reverso calibres, each shape calibres, each reintroducing one of the great classic complications. The mechanisms driving these complications had to be completely reinvented to fit the Reverso’s case and, in many interpretations, the displays re-thought to ensure balance, harmony and legibility on the rectangular dials. In 1994, the Maison pushed innovation further with the Duoface – the first Reverso to feature a second dial on the reverse side. 

More than just a stylistic contrast, its two faces opened new creative possibilities by introducing different functions on each face, transforming the Reverso into a true canvas for both artistic expression and horological ingenuity.

A WORLD OF TIME ON THE WRIST

Aside from the practical value of displaying the time in 24 major time zones simultaneously, a World Time watch exudes romance and escapism. The genesis of the complication lies in the decision made in 1884 to establish standardised global time, with the Greenwich Meridian in London as the reference, or prime meridian.

Despite numerous early attempts at world-time complications, it was not until 1931 that Geneva watchmaker Louis Cottier invented the first successful ‘Heure Universelle’ mechanism. Most modern world-timer mechanisms are derived from his inventions. Having first mastered the complication in 1958 with the Memovox World Time, Jaeger-LeCoultre’s watchmakers have introduced world timers in several models: Memovox, Geophysic, Polaris and Duometre. In 1998, Jaeger-LeCoultre introduced the Reverso Géographique, its first interpretation of the Reverso as a travel watch. This timepiece was one of the six complicated Reversos launched during the 1990s in limited editions of 500 pieces. In 2025,

La Grande Maison presents the complication in the Reverso Tribute line for the first time. The World Time complication of Calibre 834 is both easy to read and simple to set. A hidden pusher at the top of the case, accessible when the case is removed from the cradle, allows for effortless adjustment. The tactile pusher makes a sharp and crisp slide to correct the indication with a 1-hour jump.

REFINED CRAFTSMANSHIP AND TIMELESS AESTHETICS ENHANCE AN EVOCATIVE COMPLICATION

Each dial of the Reverso Tribute Geographic is a masterpiece in its own right, offering a distinct and captivating identity. On the understated front dial, the sunray finish in rich blue (for the steel case) or chocolate (for the pink gold case) complements the signature iconography of the Reverso Tribute. The large date display is contained within a frame of polished metal that matches the case and amplifies its rectangular lines. The circular small seconds display provides a counterpoint to the linear geometry and echoes the circular world time display, revealed when turning the watch over.

On the reverse side, the world time display is set into the polished caseback. On the steel model, details in shades of blue contrast with the cool tones of the metal, while the warmth of the pink gold model is complemented by black and grey details. The construction of the display on three different levels creates a remarkable effect of visual depth. The city names are engraved directly onto the caseback; set within the aperture, the rotating 24-hour ring indicates day and night; in the centre is the world map – marked with the longitudes that provide additional visual orientation in relation to the time zones.

Created in-house at the Jaeger-LeCoultre Manufacture, the map combines the crafts of lacquering and laser engraving. Beginning with a smooth disc of steel, the areas representing the oceans are hollowed out with a laser, leaving the land masses and meridian lines as raised areas. Then, lacquer is applied to fill in the oceans. Given the intricate shapes of the map and fine details of the meridian lines, the lacquer must be applied, by hand, in carefully controlled drops using a syringe. The finished disc is polished multiple times and, while a perfectly uniform finish is essential, the lacquer and metal reflect the light differently, creating a subtle three-dimensional effect.

The new Reverso Tribute Geographic is presented with two interchangeable straps designed by Casa Fagliano, the celebrated Argentinian maker of polo and riding boots. For the steel model, one strap combines leather and canvas – inspired by the canvas-and-leather boots that Casa Fagliano makes for summer polo – and one is entirely in calf leather; the pink gold model features one strap in golden-tan calfskin and another in black alligator.

A NEW INTEGRATED MOVEMENT ENTIRELY DESIGNED, PRODUCED AND ASSEMBLED IN-HOUSE

Developed specifically for the Reverso Tribute Geographic, Calibre 834 was designed, produced and assembled entirely in-house; as always at Jaeger-LeCoultre, it is a fully integrated calibre rather than an added module. Given La Grande Maison’s philosophy of designing shaped movements that closely follow the contours of their case, the rectangular Reverso creates a particular challenge when designing complications that were traditionally conceived for round movements.

 Click, to see the large size. ▶ BIG FOTO 

The integrated world time complication drives the classic style of 24-hour time zone display with a world map at its centre. However, there is a key difference in its operation: in most world timers, when setting the reference city to 12 o’clock, the city disc rotates while the 24-hour display remains static. Jaeger-LeCoultre has inverted this relationship, with a static display of city names and a rotating 24-hour ring, a design choice made to offer better legibility of the complication, and a one-of-a-kind display of the function. To ensure precise setting of the hour, the 24-hour ring jumps in hourly increments. The hours are set using a discreet pusher hidden between the lugs at the top of the case.

For the Grande Date display, Jaeger-LeCoultre’s engineers developed and patented a new shape of the date discs in 2021 to accommodate it within the confined space of the rectangular Reverso case (patent CH715152). It comprises two small side-by-side discs (one for the units 1–9 and one for the 10s, 20s and 30s) rather than two “stacked” discs, as is normal. When the date passes single digits, a tiny hook on the units disc latches on to the other disc, turning it to create the double-digit reading (10th, 11th, 12th, etc.). This has the added benefit of displaying both digits on exactly the same plane, rather than one lower than the other, to create more visual harmony.

Testament to the 180 skills gathered under one roof in Jaeger-LeCoultre’s fully integrated Manufacture, the Reverso Tribute Geographic celebrates the versatility and eternal modernity of the Reverso design, underlining La Grande Maison’s constant quest to innovate in both the mechanical and aesthetic aspects of timekeeping.

THE NONANTIEME COLLECTOR’S BOX

Along with the launch of the limited edition Reverso Tribute Geographic, Jaeger-LeCoultre releases an exclusive collector’s box commemorating the 90^th anniversary of its iconic Reverso. This meticulously crafted case is designed to house six limited-edition Reverso timepieces, each representing a pinnacle of horological innovation and artistry.

Drawing inspiration from the collector’s box created for the Reverso’s 60^th anniversary in 1991, this new edition offers a unique opportunity for discerning collectors to own a piece of horological history. Each of the six compartments within the box is dedicated to a distinct Reverso model, showcasing the timepiece’s enduring legacy and the evolution of its celebrated complications. The box itself is a testament to Jaeger-LeCoultre’s commitment to exceptional craftsmanship, combining luxury, functionality, and a timeless aesthetic.

Following the introduction in 2021 of the Reverso Tribute Nonantieme ‘Enamel’ to celebrate the Reverso’s 90th anniversary, Jaeger-LeCoultre presents a new expression of the timepiece in 18k pink gold (750/1000) with an elegant grey sunray dial and decorative enamelling on the reverse. To be made in a limited edition of 90 pieces, this new interpretation again demonstrates La Grande Maison’s constant pursuit of technical innovation married to timeless design and fine craftsmanship.

FROM POLO FIELD TO HIGH WATCHMAKING – AN ICON EVOLVES

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. The 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 (historical patent CH159982) and distinctive Art Deco lines have remained constant, making the Reverso one of the world’s most recognisable wristwatches.

This technical challenge, overtook by the Manufacture, was fully embraced in the beginning of the 1990s, when Jaeger-LeCoultre introduced high complications in Reverso. In 1991, marking the 60th anniversary, the Reverso Soixantieme displayed a power reserve and date, with another first – a sapphire crystal caseback, to observe the mechanical treasure within. During the decade that followed, five of the great classical complications were reinterpreted, with the movement architecture and visual displays reimagined for the rectangular Reverso case. Then, to mark the completion of another decade, the Reverso Septantieme was introduced in 2001.

In 2021, the 90th anniversary of the Reverso’s birth, Jaeger-LeCoultre created the Reverso Tribute Nonantieme. It brought a fresh and exciting stylistic language to the Reverso, presenting an entirely new visual expression of some of watchmaking’s most familiar complications.

A NEW COLOUR FOR THE FRONT DIAL; ENAMEL AND LACQUER ENHANCE THE REVERSE SIDE

Driven by its continuing exploration of beauty and refined craftsmanship, the new interpretation of the Reverso Tribute Nonantieme ‘Enamel’ features an elegant grey sunray-brushed dial and a richly decorated reverse side. The simplicity of the Reverso Tribute iconography – elongated applied indexes, Dauphine hands and a chemin de fer minutes track – places the emphasis on the complications. The ‘Grande Date’ display at 12 o’clock is highlighted by an applied pink golden-coloured frame that echoes the rectangular shape of the case and dial. In the lower half of the dial within the small seconds counter, a moon phase display is set against the background of stars in a deep blue sky. While the colours of these details echo those on the reverse dial, the classically elegant aesthetic gives no hint of the surprise that awaits when flipping the case over.

Turning the case reveals the Nonantieme’s distinctive and visually exciting displays wrapped in the beauty of a starry night sky. The dial comprises two round apertures of different sizes, overlapping and arranged like a figure-eight, which is encircled by gadroons that echo those on the upper and lower edges of the case. The small upper aperture displays a semi-jumping digital hour indication against a white background. Below the hour, the large aperture displays minutes on a rotating disc that is partially concealed by a three-quarter plate, lacquered in a rich shade of blue. Tiny pink gold stars are transferred onto the surface of the lacquer to depict the night sky. Within a smaller circle at the centre, a polished sun and moon indicate night and day as they pass above a horizon. The semi-circle below the horizon is decorated with a guilloché pattern of sunrays and the entire lower aperture is framed by a circle of pink gold beading (18k, 750/1000).

The larger surface surrounding the indications – which had been an unbroken expanse of pink gold in the original Nonantieme – is transformed into a starry night sky with multiple layers of rich blue enamel sprinkled with stars. The latitude and longitude lines are engraved with a hand-held laser to reveal the underlying pink gold case metal.

CLASSIC COMPLICATIONS REINVENTED THROUGH MECHANICAL INNOVATION

Showing the same time on both faces of the watch and comprising 243 components, Calibre 826 was conceived specifically for the Reverso Tribute Nonantieme ‘Enamel’ and was developed, produced and assembled entirely in-house.

Given La Grande Maison’s philosophy of designing movements that closely fit the shape of their case, the rectangular Reverso creates a particular challenge when designing complications that were traditionally conceived for round movements. 

 Click, to see the large size. ▶ BIG FOTO

To accommodate the Grande Date display within the confined space of the upper dial, in 2021, Jaeger-LeCoultre’s engineers developed a completely new mechanism comprising two small side-by-side discs (one for the units 1–9 and one for the 10s, 20s and 30s) rather than two “stacked” discs, as is normal. When the date passes single digits, a tiny hook on the units disc latches on to the other disc, turning it to create the double-digit reading (10^th, 11^th, 12^th…etc). This patented invention has the additional benefit of displaying both digits of the date at exactly the same level, rather than one slightly lower than the other.

Although La Grande Maison’s watchmakers had incorporated the digital hours complication in some calibres during the 1930s, they have used it rarely in recent decades. For the display, Jaeger-LeCoultre’s engineers opted for a semi-jumping rather than instantaneously jumping mechanism to allow for a more gradual and elegant transition. Also, because an instantaneous jump requires a large and sudden burst of energy, this choice safeguards the power reserve.

Offered in a limited edition of 90 pieces, this new interpretation of the Reverso Tribute Nonantieme ‘Enamel’ underlines the timelessness and versatility of the Reverso, as well as La Grande Maison’s continuing commitment to craft and creativity alongside mechanical innovation and excellence.
