 Jaeger-LeCoultre presents the Master Hybris Mechanica Ultra Thin Minute Repeater Tourbillon, a new interpretation of the Maison’s celebrated ultra-thin calibre that unites a minute repeater with a flying tourbillon. Set in an 18K Pink Gold case (750/1000) measuring just 8.25 mm thick, the entire mechanism is open to view, its movement revealed by utilising the transparent property of sapphire, and the pared-back dial that forms an open-worked ring encircling the movement. The subject of seven patents – six of which were developed specifically for the launch of Calibre 362 in 2014. The watch unites some of horology’s most notable feats, including a fully flying one-minute tourbillon and a beautifully sonorous minute repeater.

A GREAT LEGACY: 

CHIMING WATCHES, ULTRA-THIN CALIBRES, TIMING PRECISION

Representing a major technical breakthrough and an innovative aesthetics when it was introduced in 2014, Calibre 362 draws upon Jaeger-LeCoultre’s remarkable heritage in two key areas: chiming complications and precision timekeeping. It remains the world's thinnest automatic minute repeater tourbillon.

Jaeger-LeCoultre’s expertise in ultra-thin movements dates back to the collaboration between Jacques-David LeCoultre and Edmond Jaeger, which resulted in the record-breaking 1.38 mm-thick Calibre 145, introduced in 1907.

Since creating its first tourbillon movement in 1946 and its first tourbillon wristwatch in 1993, the Maison’s quest for ever-greater timekeeping precision has resulted in multiple inventions in both the construction of tourbillon cages and the shape of hairsprings, optimised for different forms of regulating organs. Since 1870, when La Grande Maison introduced its first minute repeater, Jaeger-LeCoultre has crafted more than 200 different repeating calibres. The Manufacture’s investment of time and energy into researching striking complications and the quality of their sound, timbre, volume and cadence has resulted in many patents, including several incorporated into Calibre 362.

 Rather than superimposing separate layers for each complication, Calibre 362 was conceived from the outset as a fully integrated movement. The minute repeater is not added onto a base calibre; it forms an intrinsic part of the architecture. This integration is fundamental to achieving the exceptional thinness of the movement. The striking mechanism was entirely re-engineered to occupy minimal vertical space. Its optimised construction accounts for approximately one third of the calibre’s total volume, demonstrating how carefully each component was calculated to reduce thickness without compromising acoustic performance. By rethinking the layout of the racks, hammers and gongs within the main plate, Jaeger-LeCoultre’s engineers eliminated the need for additional layers traditionally required in repeater constructions.

Equally instrumental to the slender profile is the flying tourbillon that comprised 59 components and weights 0.248 grams. Suspended without an upper bridge, the one-minute flying tourbillon reduces structural height while enhancing visual lightness. The absence of an upper support not only contributes to the aesthetic transparency of the movement but also removes superfluous material, optimising vertical space.

The oscillating mass also plays a decisive role. Instead of a conventional central rotor, Calibre 362 is equipped with a peripheral oscillating mass that encircles the movement. This ingenious solution eliminates the additional thickness of an overlaid winding rotor, preserving the ultra-thin profile while ensuring efficient automatic winding. Minute repeater integration, flying tourbillon construction and peripheral winding system - each element was conceived not as an addition, but as a structural contributor to thinness.

LIGHTNESS, TRANSPARENCY AND VISUAL CONTRAST

This Hybris Mechanica Edition of Calibre 362 has been designed to showcase the entire movement - its assembly alone requires seven weeks - revealing the delicacy of its 593 components, including the entire operating sequence of the minute repeater mechanism and the captivating dance of the tourbillon.

To reveal and amplify this beauty, skeletonisation – meaning creating openings within the existing bridges of the Calibre – would be the traditional means. However, for Jaeger-LeCoultre, this was not sufficient, as the structural parts of the bridges and plates, which are essential for a movement's function, would still limit the visibility of part of the Calibre.

Sapphire Bridges, an innovative solution: Three bridges, essential for the structural stability of the movement, are meticulously constructed from transparent sapphire crystal rather than metal. This represents a significant accomplishment for the Maison, as creating sapphire bridges directly within the movement presented several technical challenges, notably the precise setting of its all-important 11 ruby jewels. Since direct setting into the sapphire was not feasible, 18K Pink Gold (750/1000) chatons were ingeniously employed – a technical feat that not only resolved the challenge but also enhanced the calibre's aesthetic beauty. To enhance their transparency and visual purity, the sapphire bridges are finished with polishing, anti-reflective coating, and an anti-static treatment.

14 different decorative techniques: The calibre's aesthetic brilliance is underscored by various finishes, including those on the case: sandblasting, perlage, polishing, flat polishing, straight graining, linear brushing, circular brushing, Côtes de Genève, diamond polishing, snailing, sunray brushing, bevelling, and guillochage. The exceptional precision of this hand-finishing is evident across all components, from the hand-bevelling and perlage to the varied brushing and polishing on diverse surfaces. This dedication to detail is exemplified by the 48 inner angles and 60 hand-bevelled components that adorn the movement.

An exceptional dial: The dial is elegantly complemented by an 18K Pink Gold (750/1000) case, distinguished by a variety of surface finishes that enhance the play of light across its contours – an aesthetic approach newly introduced for this calibre. Encircling this intricate display, the dial is pared back to form an open-worked ring of 18K White Gold (750/1000) around the movement’s periphery, revealing the elegantly guilloché in-house 18K Pink Gold (750/1000) winding rotor, a masterpiece crafted within Jaeger-LeCoultre’s Métiers Rares™ ateliers. To create visual contrast, the applied hour markers in 18K Pink Gold (750/1000) and the Jaeger-LeCoultre logo are matched with the hands and the winding rotor.

The art of integration: The complex case, designed and reinterpreted for the ultra-slim Calibre 362, is composed of 60 parts. Developed for the original Calibre 362, an innovative alternative to the conventional slide that activates a minute repeater combines a patented, retractable button at 10 o’clock that activates the function with a second button at 8 o’clock that locks and releases it. These buttons have been redesigned particularly for Hybris Mechanica Calibre 362 to integrate perfectly into its new case.

A MASTERPIECE OF TECHNICAL INVENTIVENESS AND THINNESS

Testament to the Manufacture’s enduring quest to create the ‘perfect’ chime, the minute repeater of Calibre 362, made of 187 components, features a striking mechanism designed from its inception in harmony with the regulating organ and automatic winding system. This design enables both exceptional acoustic performance and extreme thinness. Integrated directly into the calibre’s main structure, the minute repeater features one-piece, square-profile gongs optimised for tonal purity and resonance. These are paired with articulated trebuchet-style hammers that strike the gongs with greater velocity and precision, generating a sound that is at once powerful and refined.

Invented specifically for Calibre 362, the Manufacture’s patented silent time-lapse reduction mechanism further exemplifies this philosophy of integration. By dramatically minimising the pause between the hour and minute chimes – particularly in the absence of a quarter-hour strike – it ensures a fluid, uninterrupted acoustic sequence.

The transparency of the flying tourbillon is enhanced by both the cutaway in the base plate and the absence of cocks or bridges holding it in place, as well as the patented flying balance wheel. To ensure slimness while ensuring the most concentric ‘heartbeat’, and therefore timekeeping accuracy, Jaeger-LeCoultre’s engineers invented and patented the S-shaped hairspring, which is also fully visible thanks to the absence of a tourbillon bridge. The invention of this novel spring shape was necessitated by the particular construction of the tourbillon and the requirement for overall slimness of the calibre.

 Click, to see the large size. ▶ BIG FOTO 

Three key innovations have made the technical beauty and complexity of Calibre 362 possible within an ultra-thin self-winding movement measuring just 5 mm in height.

The oscillating weight that winds the mainspring is designed as a peripheral rotor, with the dual benefit of adding no thickness to the calibre while also making the beauty of the movement fully visible from both the dial side and the back of the watch. Mounted on 36 specially conceived ceramic ball bearings and activated by the movement of the wearer’s wrist, it moves freely in both directions for optimal winding efficiency.

 Click, to see the large size. ▶ BIG FOTO 

The new Master Hybris Inventiva Gyrotourbillon À Stratosphère is the latest in a long line of inventions nurtured by Jaeger-LeCoultre’s pursuit of precision, which began almost two centuries ago. The triple-axis tourbillon construction of Calibre 178, for which several patents have been filled, ensuring 98 percent coverage of all possible positions, is arguably the most precise tourbillon wristwatch with the widest positional coverage ever created by Jaeger-LeCoultre. It also marks the inauguration of a new series within the Hybris line: Hybris Inventiva. Nestled within a finely finished 42 mm platinum case, the calibre housing the new triple-axis tourbillon is meticulously finished and hand-decorated with Métiers Rares™ including guillochage, enamel and lacquer to highlight its distinctive architecture.

HYBRIS INVENTIVA: 
A NEW LINE HONOURING TECHNICAL BREAKTHROUGHS

Jaeger-LeCoultre unveiled the Hybris Mechanica series in 2003 as a collection inspired by a spirit of invention and a desire to push the boundaries of watchmaking by combining several reimagined high complications into one timepiece. The Hybris Artistica concept was revealed in 2014 as a collection of Métiers Rares™ expressions of existing high-complication models, designed to highlight the rare artistic handcrafts such as engraving, enamelling and guilloche that are brought together within the Manufacture. Now Jaeger-LeCoultre unveils a third Hybris line: Hybris Inventiva.

Timepieces featured for the Hybris Inventiva series will only ever showcase a single complication – but one so remarkable and groundbreaking that it will change the course of the Maison’s history. The Hybris Inventiva name is apt, since the calibres evolve from internal discussions hypothesising the invention of “impossible” complications. These discussions can last for years but, despite their apparent impossibility, the groundbreaking ideas eventually evolve into real research pieces that are worked on and tested for more years – and at times decades – with only a handful of people inside the Manufacture aware of their existence. This allows the master watchmakers and engineers the space and time needed to make possible the apparently impossible.

Until now, such exploratory prototypes were kept in-house as highly confidential and purely conceptual pieces. With the Hybris Inventiva series, after many more months or even years of testing the prototype calibres, Jaeger-LeCoultre officially reveals the breakthrough to the public, always in very limited, numbered editions. Following the modèle maître (master model) principle, a Hybris Inventiva piece may then become the basis for potential future reinterpretations – whether combined with other complications in an extraordinary calibre to become a Hybris Mechanica (ultra-complication) piece and then reinvented through the artistic lens of the Métiers Rares™ atelier as a Hybris Artistica piece.

A NEXT-GENERATION MULTI-AXIS TOURBILLON

The tourbillon was initially invented for pocket watches to help combat the greatest enemy of precision: gravity. As the pocket watch was worn upright in one position, gravity eventually influenced the accuracy of its movement.

The tourbillon, which spins the movement’s oscillating system around its own axis in a regular rhythm, was invented to effectively counter this natural effect. Today, with wristwatches being the prevalent personal timekeeper, watchmakers understand that multiple-axis tourbillons do much more than a single-axis tourbillon to prevent gravity from influencing their precision.

 In 2004, Jaeger-LeCoultre embarked on a groundbreaking series of multiple-axis inventions with the unveiling of the first Gyrotourbillon. The first generation of the revolutionary double-axis tourbillon was meticulously engineered to ensure its oscillating system was never stationary in the horizontal position, solidifying Jaeger-LeCoultre’s pioneering role in multi-axis tourbillons.

Building upon this foundational achievement, each subsequent generation of the Gyrotourbillon pushed the boundaries of precision and artistry. The second generation was distinguished by a new construction meticulously tailored to fit the iconic Reverso case. The third generation then ushered in the first Flying Gyrotourbillon, graced with the innovation of a spherical hairspring. The fourth generation achieved a full flying status, becoming the fastest Gyrotourbillon to date. The fifth generation showcased a triumph of miniaturisation, harmoniously integrating the Gyrotourbillon with a constant force mechanism.

 Now, representing almost eight decades of accumulated expertise in tourbillon regulators, the Master Hybris Inventiva Calibre 178 Gyrotourbillon À Stratosphère, for which several patents have been applied for, takes the technology even further, to become a tourbillon within another tourbillon within yet another tourbillon. The kinematics of this triple-axis tourbillon achieves 98 per cent of all possible positions to compensate for the negative effects of gravity on the precision of the watch.

To optimise isochronic performance, the Gyrotourbillon À Stratosphère is fitted with a cylindrical balance spring – a shape that beats concentrically in every position, regardless of amplitude (the back-and-forth swing of the balance wheel), position or power reserve – and runs on ceramic ball bearings to minimise friction. Its three titanium tourbillon cages rotate along X, Y, and Z axes at three different speeds – respectively, 20 seconds (inner cage); 60 seconds (centre cage or ‘cage of reference’); 90 seconds (outer cage) – to ensure that all positions are constantly covered. No other 4 Hz tourbillon on the market currently covers such a wide range of positions, giving gravity almost no chance to adversely affect the precision of the oscillator. The development of this supposedly impossible feat was initially sparked by the invention of the Gyrotourbillon, which already reached an outstanding 70 percent positional coverage in 2004.

For the last 22 years, Jaeger-LeCoultre has worked to improve upon that tourbillon’s miniaturisation, as well as different angles of inclination of the axes, eventually leading to the creation of the ultra-precise Gyrotourbillon À Stratosphère. Taking its name from the ‘quiet layer’ of Earth’s atmosphere – the optimal cruising altitude for large jets, unaffected by turbulence – the Gyrotourbillon À Stratosphère is composed of 189 components – almost double the number of components typically found in an entire time-only mechanical calibre – while only weighing 0.783 grams.

SCULPTURAL BEAUTY HIGHLIGHTED BY ARTISTIC DECORATION

Calibre 178 stands as Jaeger-LeCoultre's most profound achievement in harmonizing mechanics and decoration. Unprecedentedly, techniques typically reserved for the dial have been meticulously applied across its barrel covers, plates, and bridges, forging a seamless visual tapestry that utterly blurs the distinction between the dial and the movement. This transforms the calibre itself into a breathtaking work of kinematic art. Calibre 178 is decorated with 16 different techniques: sandblasting, perlage, polishing, flat polishing, straight graining, linear brushing, circular brushing, Côtes de Genève, diamond polishing, snailing, sunray brushing, bevelling, guillochage, lacquering, lapping finish, and enamelling.

65 hours of hand-bevelling: The sheer scale of this artistry is vividly demonstrated by the meticulous hand-bevelling. This intricate work is applied to 55 individual components – including 20 bridges, 18 cage components, 11 wheels, and 6 parts of the mechanism – and features an astonishing 64 inner angles, a true testament to extreme precision. Furthermore, the calibre incorporates 33 components crafted from solid gold. The use of such precious materials for plates and bridges presents an additional challenge during assembly, requiring the watchmaker to exercise exceptional care and skill.

A front-side adorned with blue enamel: On the front of the watch, the 18K white gold movement plates are decorated with sunray guilloché and then coated with translucent blue enamel. The visible hollowed-out 18K white gold bridges are filled with blue lacquer to match the design, and even the covers of the two large spring barrels – unmistakable from the dial side at approximately 2 and 10 o’clock – are engraved and hand-lacquered in the same blue.

A fascinating play of volume: The decoration continues on two decentralised dial rings: the top ring bearing the hour-and-minute display reveals not only the hand arbour in its open-worked centre but also more of the decorated twin spring barrels. The second decentralised ring surrounds the triple-axis Gyrotourbillon A Stratosphere at 6 o’clock and displays markings for 30 seconds (twice 15 seconds); the seconds are displayed by a small red arrow that travels around this subdial. The visuals add to the sculptural conception of the calibre, which plays with volumes in a fascinating manner. The spotlight, however, remains fully on the centrepiece: the triple-axis Gyrotourbillon À Stratosphère.

A spectacle revealed on the caseback: The entire back of the watch is visible beneath a transparent sapphire crystal case back, providing the owner with an excellent view of Calibre 178’s support system. This features solid White Gold 18K bridges, traditionally decorated with Côtes de Genève, hand-bevelling, and high polish. These are complemented by 53 ruby jewels, some in gold chatons, whose deep red color contrasts with the monochrome white gold-and-steel aesthetic. 

The design of the highly polished stainless-steel bridge holding the Gyrotourbillon À Stratosphère from the back was inspired by the tourbillon bridge of Jaeger-LeCoultre’s seminal 1946 pocket watch tourbillon. For this, and the bridge supporting the hours-minutes arbour, stainless steel was chosen rather than gold, due to the need for a much more resistant material in these two positions.

Precision and power reserve: Ensuring high precision, the manually wound Calibre 178 beats at 4 Hz (28,800 vph) and offers a remarkably long power reserve of 72 hours, requiring a rewinding once every three days.

As a Hybris Inventiva piece, the apparently simple elegance of the platinum case belies a complexity of detail. Polished, brushed and micro-blasted finishes create a fascinating play of light with every movement of the wrist, perfectly complementing the complexity of the groundbreaking technical achievement within.

In 2025, La Grande Maison presents a new interpretation of the Master Grande Tradition Calibre 948 with an enamel dial set in an 18K (750/1000) pink gold case. A uniquely artistic expression of universal time, Calibre 948 combines a world-time display with a flying tourbillon that makes a complete circuit of the dial in 24 hours: an allusion to Earth’s rotation on its axis and its orbit around the Sun. Showcasing the skills of Jaeger-LeCoultre’s in-house Métiers Rares™ atelier, the new interpretation of Calibre 948 is offered in a limited edition of 20 pieces.

A TOURBILLON THAT TRACKS THE PASSING OF THE HOURS IN EVERY CITY

As with all measurements of time, the origin of our world’s time zones lies in astronomy, the passage of the 24-hour day being determined by the rotation of Earth on its own axis. However, time zones are a relatively recent concept. Until the 19th Century, every city determined its own time, based on 12 noon being the time that the sun was at the highest point in the sky, regardless of the city’s latitude or longitude. 

At the International Meridian Conference in 1884, when it was decided that standardised timing and global norms were needed, Greenwich Observatory in London (longitude 0°) was chosen as the basis for calculating the world’s time zones, hence the term Greenwich Mean Time (GMT). For almost a century, Jaeger-LeCoultre has been distinguished by its mastery of complications able to display multiple time zones simultaneously.

Like all classical world timers, Calibre 948 identifies each time zone by the name of a city, which is inscribed on a blue opaline ring surrounding the central dial. Beyond the city ring are two concentric fixed rings. The inner ring indicates 24 hours, which are marked with applied indexes and laser-engraved numerals, and the outer ring features the minute track, which is a laser-engraved on a background of blue lacquer.

  In a circular aperture to one side of the world map, the universal flying tourbillon appears to float weightlessly above the oceans, spinning in 60 seconds. As the tourbillon makes a complete 360-degree circuit of the dial in 24 hours, the domed map and the city ring turn in unison, mimicking the rotation of Earth. 

A WORLD OF TIME EXPRESSED THROUGH THE MASTERY OF ANCESTRAL CRAFTS

To create the complex and richly coloured dial of the Master Grande Tradition Calibre 948, the master artisans of Jaeger-LeCoultre’s Métiers Rares™ atelier united the skills of champlevé enamelling for the continents, with hand-guillochage and hand-lacquering for the oceans.

Measuring just 25.5mm in diameter, the multi-layered dial of the Master Grande Tradition Calibre 948 is a remarkable work of art in miniature. In keeping with world-timer tradition, the centre of the dial is dominated by a map of the world as seen from the North Pole. The outline of the continents is cut from a fine plate of 18K pink gold (750/1000) and decorated with champlevé enamel. However, unlike the traditional flattened image, this map floats above the main dial plate on a domed skeleton formed by the longitudes and latitudes of the Northern Hemisphere.

A masterpiece of laser-cutting precision, this complex and delicate domed structure brings lightness and depth to the dial and makes a subtle allusion to the depth and complexity of time measurement. Beneath the dome, representing the oceans, the dial plate is decorated with blue translucent lacquer applied over a wavy hand-guilloché pattern that suggests the movement of the sea. Champlevé - which translates literally as ‘raised field’ - is a noble and ancient enamelling technique. The first step is to carve out depressions in the surface of the precious metal, conforming precisely to the outline of the desired image. These hollow areas are then filled with multiple layers of enamel, fired at very high temperatures after each layer, until they are flush with the original surface. Adding refinement and visual interest, the enameller uses a combination of opaque and translucent enamels to create areas of lighter and darker colour that suggest the continents’ different landscapes. The Calibre 948 dial required the meticulous work of nine layers of enamel for the dome.

Lacquering is a lengthy and exacting artisanal process used in the creation of the ocean dial plate. It involves the manual application of multiple layers of coating on the surface to be decorated. It begins with a clear coat of varnish, followed by a layer of colour. This is followed by up to 15 coats of translucent lacquer, to add depth and richness, with each coat requiring a precisely controlled drying process. The lacquering is completed by polishing the disc to a perfect finish that attracts the light and amplifies the richness of the colour. 

AN EXCEPTIONAL CALIBRE COMPLEMENTED BY AN ELEGANT CASE

When Jaeger-LeCoultre created Calibre 948, it was the first time that a world-time complication had ever been united with a flying tourbillon. Moreover, the Universal Tourbillon, patented by Jaeger-LeCoultre, makes a complete circuit of the dial every 24 hours, corresponding to the length of a mean solar day. Consisting of 388 components, the automatic movement is an eloquent expression of Jaeger-LeCoultre’s technical expertise, having been conceived, developed and entirely produced within the Manufacture.

Despite its complexity, Calibre 948 has been designed to ensure that the watch is very simple to operate: the time is set with the crown, which synchronises all the time zones around the world. On arrival at a new destination, local time is set by the same crown, which moves only the hour hand, in one-hour jumps forwards or backwards, as the minutes and seconds continue running. With its pure lines and refined proportions, the Master Grande Tradition case is a perfect foil for the complexity of the dial. Comprising more than 40 parts, its convex bezel contrasts with broad bevels on the lugs, and the hollowed-out lug sides add dynamic tension. Different surfaces are micro-blasted, polished and satin-brushed to maximise the play of light. The warmth of the pink gold is complemented by a dark blue alligator strap.

Deftly balancing the robust capabilities and practical functions of a sporty watch with Jaeger-LeCoultre’s signature elegance, the Polaris line pays direct homage to the Maison’s emblematic diving watches of the 1960s, capturing their sporting spirit and reinterpreting their vintage appeal in elegant and confidently contemporary style.

With the versatility of both a casually elegant everyday timepiece and a high-performing sports watch, the Polaris Chronograph is designed for optimal comfort on the wrist. Well-balanced and highly wearable, its 42mm steel case features the key Polaris design codes: taut lines, sharply curving lugs, a thin bezel, a glass-box crystal, and an eye-catching mix of brushed and polished surfaces. The large crown – a signature of the 1960s model that inspired the contemporary Polaris line – and robust pushers are designed for better grip and ease of use.

OCEAN GREY LACQUER ADDS FRESH ALLURE TO THE SPORTY DIAL

Anchored by the clean, modern lines of the case, the new ocean grey dial is bold and visually striking, thanks to the richness of the lacquer and the contrast of bright orange details that speak to the chronograph’s sportier side.

Complex in construction, the dial is composed of a central disc, a middle ring, to which the hour markers are applied, and an outer ring that is marked with the tachymeter scale. Sunray brushing on the central disc creates a subtle contrast with the smooth gloss of the hours ring; on both sections, the colour of the lacquer is graduated from light to dark, adding great visual depth to the dials.

The lacquering of the dial components is a lengthy and exacting process, with each layer of coating being applied manually. It begins with the application of a clear coat of varnish, followed by four layers of colour. Then a layer of black is applied to create the gradient effect. The challenge lies in controlling both the shade and the gradient, so that the two main sections of the dial match each other. This is followed by 30 coats of translucent lacquer, to add depth and richness.

The layout of the Polaris Chronograph dial is timeless and intuitive to read, featuring a central chronograph seconds hand to enable more precise reading of this key measurement. Balanced by the 30-minute counter at 3 o’clock, the sub-dial at 9 o’clock animates the dial with a running seconds display. The circular graining of these sub-dials adds more visual interest, contrasting with the glossy central dial and the textured finish of the hours ring.

Orange accents draw the eye to the key indications and add dynamism to the overall composition. In keeping with the contemporary Polaris design codes, skeletonised hands allow greater visibility of the indications and bold trapezoid-shaped indexes balance the fine detail of the chronograph displays. Luminescent coating on the indexes, numerals and the tips of the hands enhances legibility in all light conditions – an essential attribute for an adventure watch. 

HARNESSING A LEGACY OF WATCHMAKING EXCELLENCE

The sapphire crystal case-back reveals the automatic movement, Calibre 761 – a quintessential example of Jaeger-LeCoultre’s approach to watchmaking that combines high performance with mechanical elegance. Powered by twin barrels, the fully integrated chronograph movement features a column-wheel chronograph mechanism with vertical clutch and offers a 65-hour power reserve.

The fine finishing includes blued screws and Côtes de Genève decoration on the baseplate as well as on the signature open-worked winding rotor bearing the ‘JL’ motif. The movement was designed, produced and assembled by Jaeger-LeCoultre at its Manufacture in Switzerland’s Vallée de Joux.

Underlining its versatile and sporty spirit, the Ocean Grey Polaris Chronograph is presented with two interchangeable straps – one in blue-grey canvas and one in textured black rubber – enabling a change in style and attitude in a matter of moments.
