Celebrating Jaeger-LeCoultre – 175 years of the Manufacture: the Quartet of Masters

The Manufacture Jaeger-LeCoultre, or the Grande Maison as it is known in the Vallée de Joux, is celebrating its 175th anniversary this year. Since 1833, it has been located in the same place, exactly where Antoine LeCoultre decided to set up his workshop, between the lake and the woods just outside the village of Le Sentier.
Since that time, the site has expanded every two or three decades: 1866, 1874, 1888, 1912, 1933, 1946, 1955, 1972, 1997... and soon, in 2010, when the Manufacture will spread over 23,000 square metres.
Of course, the number of employees has grown accordingly, and today over 1,000 people work together at more than 40 watchmaking trades in the Grande Maison. These geographic and social roots, and this historical continuity are directly embodied in the long line of products from the Manufacture, products that have become so many watchmaking icons. The legacy of the Reverso, Master Control, and Atmos dynasties – all of which are still very much alive to tell the story – is truly one of a kind.
This exceptional story has always been at the confluence of art and technology, of the aesthetic genius and innovation that are combined and embodied in exceptional timepieces. It is the rare privilege of a Manufacture such as Jaeger-LeCoultre to master all aspects of watchmaking and be dominant in all its trades. This “universality” of expertise and mastery is the key to imagination, the lively source of the innovation that has always been the heart of the company since its very beginning. The list of the Manufacture’s conquests, “firsts” and resounding successes is too long to give here. The several thousand movements that have been created there, and the more than 300 patents registered by the company, bear witness to this. But Jaeger-LeCoultre’s greatest success has been that it has combined these sometimes spectacular innovations with a creativity and unfailingly good taste that have never disappointed. In doing so, it has created true “dynasties” of models that are immune to the passing of time and the whims of fashion. Better yet, they continually innovate and carry the great watchmaking adventure ever forward.
The new timepieces presented on these pages are ample proof of this: the Reverso Squadra Lady shows off the feminine modernity of a form born over 75 years ago; the Reverso Gyrotourbillon 2 is at the forefront of research and ultrasophisticated horology; the Master Ultra Thin models are masterpieces of classicism, with origins dating back to 1903; the highly innovative AMVOX3 Tourbillon GMT introduces a new ceramic case; the famous Polaris watch that made such a splash in the 1960s has reappeared; and the Atmos clock, with its extraordinary mechanism that is still the closest thing to perpetual motion the world has ever seen, is celebrating its 80th birthday.
On the occasion of its 175th anniversary, Jaeger-LeCoultre is also offering a limited-edition series of masterpieces intended as a collective tribute to all watchmaking expertise, in the Master Control line: Master Ultra Thin, Master Eight Days Perpetual SQ, Master Grand Tourbillon and Master Minute Repeater. These timepieces are a fitting testimony to 175 years of history, art and innovation.

Reverso Squadra Lady
A real living legend, the Reverso was invented in 1931 in answer to a challenge issued by British officers stationed in India: to create a watch that could withstand the jostling of polo, the ultimate men’s sport. The solution was simple and brilliant: the watch could be turned over in one movement to protect its dial. But right from its initial appearance, the Reverso was much more than a sport watch. Its unique elegance and Belle Horlogerie movements made it a great art deco classic and one of the only truly iconic watches that appealed to both men and women. The original pendant models, cordonnets and purse watches were succeeded by models set with precious stones and, in 1997, the ultra-feminine Reverso Duetto.
In 2006, the Reverso refocused on its sporting dimension with the Reverso Squadra: a casual urban watch with an assertive design that displayed functions and characteristics directly linked to performance and reliability: chronograph, watertight seal, time zones, metal bracelets or rubber straps, and automatic motorisation with a Manufacture-made movement. It was a true masculine icon. But history repeats itself, and women were also attracted to this “squarer” version of the Reverso.
So this year, Jaeger-LeCoultre is introducing new Reverso Squadra models, the Reverso Squadra Lady Duetto and the Reverso Squadra Lady Automatic. These pieces have kept all of the values of the original Reverso Squadra but have become fully feminine.
There are two case sizes, one completely feminine and the other of a more assertive size. Both are mounted on easily interchangeable wristbands (rubber with a metallic core or leather) and are intended for women who like to combine a sporty look and sophistication.

Reverso Squadra Lady Duetto
With its double face, one for daytime and one for evening, the Reverso Squadra Lady Duetto is the perfect symbol of this harmonious coexistence between two desires. On the front, sophistication rules with a magnificent guilloché dial, slender flowing numbers, a date display cleverly set into the circle of the “6” numeral and a centre day/night disc that warns of the approach of dawn. On the back, the black dial is sportier, the numbers more assertive, and in the centre there is a disk that is interlinked with the oscillating weight and therefore rocks back and forth with it. This is a subtle way of hinting at the watchmaking skill that went into the watch without flaunting it. And skill is certainly involved, for this watch has a single automatic movement, Jaeger-LeCoultre Calibre 968, and therefore a single rewinding mechanism to power both sides of the watch and four hands that turn in opposite directions. Truly a worthy performance!
In its steel version, the watch is decorated with diamonds on the front; in the pink gold version it has diamonds on both sides. A push-piece is provided between the horns of the case to make changing between an articulated metal bracelet and a leather or rubber strap incredibly easy.

Reverso Squadra Lady Automatic
The Reverso Squadra Lady Automatic remains faithful to the Reverso Squadra spirit. It features a silver-coloured guilloché dial with a timeless design and driven by an automatic movement, Jaeger-LeCoultre Calibre 966, with a 42-hour power reserve and date indicator which, in the most “floral” version, appears in the circle of the number “6.” The magnificently finished movement can be admired through a sapphire crystal.

Reverso Gyrotourbillon 2
In 2004, Jaeger-LeCoultre presented the Gyrotourbillon 1 watch. This exceptional creation, with its system based on the multidimensional rotation of a double carriage, fully justified the insertion of a tourbillon into a wristwatch (which is worn in constantly changing positions, unlike a pocket-watch). This year, marking its 175th anniversary in particularly grand style and further reinforcing its image as an innovative fine watchmaking Manufacture, Jaeger-LeCoultre introduces a spectacular evolution of the concept: the Reverso Gyrotourbillon 2.
Jaeger-LeCoultre Calibre 174, with its 371 parts, embodies some major new breakthroughs in this highly complex domain. Its frequency has been increased to 4Hz (compared with 3Hz for the Gyrotourbillon 1) and it has been equipped with an original cylindrical balance-spring, such as can be found in marine chronometers. Contrary to flat balance-springs, this cylindrical balance-spring is endowed with two terminal curves – one on each end – thereby ensuring a perfectly concentric beat. These twin characteristics, high frequency and a concentric balance-spring, considerably enhance its accuracy. Its faster inner carriage performs 3.2 turns per minute, meaning one turn every 18.75 seconds, while its ultra-light titanium outer carriage performs one turn per minute. Another special technical feature lies in the barrel, equipped with a torque restrictor. This means that the regularity of its rate is perfectly guaranteed for 50 hours: when the torque is insufficient, the restrictor comes into action and stops the watch. In the same way, the restrictor blocks manual winding when there is a risk of surplus energy.
This exceptional shaped movement is magnified by taking its place within a Reverso case that enables one to view it in full from both sides. Aesthetically speaking, it is the very structure of the movement that creates the decorative effect: a double three-dimensional face, strongly structured by the movement bridges featuring both depth and volume and highlighted by a series of meticulous and contrasting finishes. The polishing of the central large bridge, which bears a small transparent sapphire crystal dial, is enhanced by a Clous de Paris hobnail motif providing a dramatic backdrop for the Gyrotourbillon and enabling the observer to literally plunge into its depths. The dial with its blued steel hour and minute hands sits above the two large wheels. The left-hand wheel is engraved with a 24-hour indication.
The back affords an admirable view of the intricate workings of a large gear train, and especially that of the large central wheel with its toothing inclined so as to transmit the energy to the tourbillon, which is also inclined. Meanwhile, the power-reserve indicator appears in the top-right section. The highly technical decoration is accentuated by the superlative quality of the finish featuring various types of polishing and hand bevelling: nothing has been left to chance. Once again, the Reverso demonstrates its exceptional ability to welcome the very best of horological expertise.

Memovox Tribute to Polaris
In 1963, Jaeger-LeCoultre made the first prototypes of a watch that was to become legendary: the Memovox Polaris. It was the only diving watch with automatic winding, a calendar and an alarm function, and 1,714 of them were made between 1965 and 1970. It was also anti-magnetic and had a patented triple-backed Compressor case with a bronze inner case-back designed to amplify the alarm’s sound and vibrations, an intermediate case-back that was watertight to 200 meters, and an outer case-back that had 16 holes. The purpose of this complex arrangement was to improve the transmission of the sound underwater. However, it was not only its exceptional technical characteristics that made this an iconic watch. That status had a great deal to do with its design. The absolutely modern Polaris marvellously combined cutting-edge functions and sporty yet sophisticated elegance in its rotating inside bezel, its luminescent hands and hour markers, and its alarm disc in the centre of the dial. The Memovox Polaris is a highly sought-after collector’s item and has become as rare as it is desirable.
This year, Jaeger-LeCoultre is paying a special tribute to it by offering two exceptional reissues of this “cult” watch – the 1965 model, of which 65 are being made in platinum; and the 1968 model, of which 768 are being created in steel. Everything about it – the design, the case, the domed plastic glass, the crowns – is identical, except that the movement has been completely redesigned. The Memovox Tribute to Polaris, presented in its vintage box, is now equipped with Jaeger-LeCoultre Calibre 956, which obviously incorporates all of the Manufacture’s new specifications for automatic movements (variable-inertia balance, ceramic ball bearings, high frequency).

Master Ultra Thin
Not only are ultra-thin watches part of the Manufacture’s oldest legacy; they are also the very reason for the association of the two names Jaeger and LeCoultre.
Edmond Jaeger (1858-1922) was a famous French watchmaker. He was inventive, ingenious and ambitious in his business affairs; in 1890, he began supplying chronometers for the ships of the French navy. After the bottom fell out of the chronometer market, he decided to begin making watches he wanted to be “the thinnest in the world.” Accordingly, he issued a challenge to the Swiss manufacturers. It was Jacques-David LeCoultre who took up the gauntlet. The two men met in 1903, signed a first agreement, and in 1907 the 1.38 mm-thick LeCoultre Calibre 145 became the world’s thinnest watch (and still is today, in its own category). In 1937, the two companies officially established the Jaeger-LeCoultre brand.
One of Edmond Jaeger’s requirements was, of course, that the ultra-thin calibres be created without compromising quality and reliability in the least. Calibre 145 was made for over a half-century. At the same time, extreme thinness was combined with complications. The LeCoultre Calibre 17/18RMCCVEP was barely 3.55 mm thick and had a chronograph and repeater!
This tradition continued throughout the 20th century. Today, Jaeger-LeCoultre intends to revive it by creating a real ultra-thin “hub” within the Manufacture and by introducing two new creations this year under the name of Master Ultra Thin. One version is 38 mm in diameter (hours and minutes) and manually wound; the other is 40 mm in diameter (hours, minutes and small seconds) and automatically wound.

The Master Ultra Thin 38 houses Jaeger-LeCoultre Calibre 849, created in 1994 and just 1.85 mm thick. It is one of the thinnest movements in existence today. An amazing watchmaking feat, its fine architecture demands extraordinary precision in machining. To limit its thickness, it has a barrel with no bridge and a very small escapement. The especially delicate tasks of timing, adjusting and mounting this watch are entrusted to the Manufacture’s specialty workshop, known as the Atelier des Spécialités Horlogères.

The Master Grande Ultra Thin is equipped with the new automatic Jaeger-LeCoultre Calibre 896, which is 3.98 mm thick. Derived from Jaeger-LeCoultre Calibre 899, it also has a small seconds hand and incorporates all the latest technical innovations developed for the most recent generation of Jaeger-LeCoultre automatic movements: a variable inertia balance wheel, ceramic ball bearings and high frequency.
Aesthetically speaking, their absolute purity, the spareness of their strict classicism, and their razor-thin steel or pink gold cases show off their slimness and place these new Master Ultra Thins firmly within the Manufacture’s tradition of ultra-thin masterpieces.

80th birthday of the Atmos
The Atmos clock is doubtless the object that draws closest to the ideal of perpetual motion. It was born 80 years ago in 1928, when a young engineer named Jean-Léon Reutter presented his first perpetual clock, which attracted international media coverage. It would take several more years and the genius of the watchmakers of the Grande Maison in the Vallée de Joux to transform the initial prototype into a superb clock.
The Atmos draws its energy from the smallest changes in temperature. A shift of just one degree is enough to wind it for two days. One particularly striking way of expressing its exceptional nature is the fact that 60 million Atmos clocks would jointly burn the same amount of energy as a 15-watt electric light-bulb. The Atmos is undoubtedly the world’s lowest energy-consuming mechanical system. It winding system is based on the dilation of a gas. Changes in temperature act directly on a gaseous mix contained within an hermetically concealed capsule, by dilating it when the temperature rises or compressing it when it drops. The capsule swells and subsides like an accordion bellows and constantly winds the clock movement.
In the course of its history, the Atmos has been interpreted in many different ways: from classic to contemporary and from simple to exceedingly complex – like the Atmos Mystérieuse, the Atmos Régulateur and the transparent Atmos du Millénaire with its dial displaying the years until the year 3000!
During its 80-year history, the Atmos, of which the technological principle is still unique in its kind, has amply demonstrated its ability to adjust to both aesthetic and stylistic changes. It is preparing to evince this amazing adaptability once again during this anniversary year, with three creations that vividly illustrate its huge potential: an Atmos Marqueterie embodying the finest craftsmanship traditions; an Atmos Astronomique in a tribute to Haute Horlogerie; and an Atmos created with the help of designer Marc Newson.

Atmos 561 by Marc Newson
Created in cooperation with this world-famous young Australian designer, the Atmos 561 by Marc Newson renews the art of clockmaking. Its beautifully balanced and simple design is both unexpected and yet self-evident, achieving an uncluttered, pure aesthetic. Its Baccarat crystal bubble-like cabinet houses a movement indicating the hours, minutes, months and moon phases. It once again demonstrates the astonishing aesthetic plasticity of the Atmos, which is apparently capable of perpetually living on air – and in tune with its times.

Atmos Astronomique
Inspired by the Harmonica Macroscomica, a chart of the sky created in 1660 by the German mathematician and cartographer Andreas Celarius, this magnificent Atmos Astronomique is equipped with a new movement featuring a mobile chart of the zodiac constellations in the Northern hemisphere, as well as an equation of time display. The latter complication indicates in minutes the difference between “real time” (or astronomical time) and legal time in a given place. It must therefore be adjusted according to the location (an operation facilitated by an adjustment table available on the Jaeger-LeCoultre website).
The Atmos Astronomique perfectly embodies the kind of technical challenges that Jaeger-LeCoultre constantly takes up. It was crucial that these astronomical indications should be conceived in such a way that they would involve no additional energy consumption! The challenge has been successfully met. The Atmos Astronomique, issued in a limited edition of 48, is housed within a glass cabinet enhanced by two glass sides engraved with a constellations motif.

Atmos Marqueterie
Finally, for the 80th anniversary of the perpetual clock, the Manufacture has created three limited series of 10 clocks each, graced with marquetry-work reproductions of three paintings by Gustav Klimt. They adorn a cabinet specially created for the occasion and fitted with an automatic opening system based on a gear train and barrel in many ways reminiscent of a clock mechanism. The doors of this cabinet open to reveal a second inner glass cabinet housing an Atmos Régulateur indicating the hours, minutes, months and moon phases. This precious marquetry work was entrusted to Jérôme Boutteçon, winner of the “Best French Craftsman” award, with whom Jaeger-LeCoultre has enjoyed longstanding cooperation. It is important to remember that some marquetry motifs require over 2,000 parts, over 200 different types of wood and hundreds of hours of meticulously patient, high-precision work.

AMVOX3 Tourbillon GMT
The fruitful cooperation between Jaeger-LeCoultre and Aston Martin has successively given rise to the AMVOX1 Alarm, an extremely beautiful alarm watch, and to the AMVOX2, an exceptional chronograph unique in its kind and vertically activated by simply pressing the watch glass. Now comes the AMVOX3 Tourbillon GMT, which showcases the ultimate horological complication, the tourbillon, within a technical, sporting and prestigious stage-setting. Above and beyond this spectacular new mechanism, the AMVOX3 is also a watershed model representing Jaeger-LeCoultre’s first incursion into the world of high-tech ceramics.
For its first round ceramic case, Jaeger-LeCoultre has opted for a cutting-edge process capable of guaranteeing that the AMVOX3 tourbillon GMT meets the quality standards imposed on an Haute Horlogerie watch. A mixture of zirconium and yttrium oxides is heated at high pressure to a temperature of over 2000 degrees Celsius so as to combine the two components into strongly cohesive blocks. To avoid any risk of porosity, the homogeneity of the material is also subjected to radioscopic scrutiny. This process is the only way to guarantee the correct machining of high-end ceramics and to achieve extremely precise contours of the watch. This final stage calls for the use of special tools coated in diamond crystals as well as diamond powders for polishing. The type of ceramics used by Jaeger-LeCoultre therefore features peerless resistance and stability, for a material that is barely harder than titanium, as well as far lighter and twice as hard as steel (1,500 Vickers compared with 600 for steel).
This splendid intense matt black case houses an equally high-performance movement, the Jaeger-LeCoultre Calibre 988 with tourbillon regulator. This is the first movement to house one of the major innovations in the revolutionary Master Compressor Extreme LAB presented last year. Its oscillating weight has been radically redesigned both in terms of its geometrical shape and the materials used for its construction: its segment made from a platinum-iridium alloy (the densest existing non-toxic physical body, at 12% higher than 24-carat gold) is linked by arms in carbon fibre (known for its lightness and rigidity) to an arbor pivoting on ceramic ball bearings. The overall thickness is thereby reduced by 14%, the weight by 25% and friction is also far lower. This results in an improved balance between weight and inertia, as well as enhanced reliability and shock-resistance.
This movement, equipped with a variable-inertia balance (oscillating at 28,800 vibrations per hour) featuring ruthenium-coated bridges and baseplate, can be admired through a broad opening in the dial of the AMVOX2. Just below, another opening affords a clear view of the tourbillon with its ruthenium-coated (280g) grade 5 titanium carriage supported by a gilded aluminium upper bridge. The openworked design of this bridge immediately evokes the supreme automobile sophistication epitomised by Aston Martin. This clever play on openings and the striking contrast between black (for the case, inner bezel ring and numerals), 18-carat pink gold and gilded accents (on the case-back, polished crown and hands) admirably echoes the prestige, the power and the aesthetic coherence of the Aston Martin world. The dial echoing the characteristic structure of an air inlet grid also displays a patented date display which jumps instantly from the 31st of one month to the 1st of the next so as not to hide the tourbillon from view, as well as a dual time-zone display equipped with a useful AM/PM indication.

Celebrating the Manufacture’s 175th anniversary
To celebrate its 175th anniversary, Jaeger-LeCoultre has created a special limited-series collection. Four models and four complications have been chosen to make up this collection testifying to the watchmaking mastery of the Manufacture, a meeting point between mechanical beauty and aesthetic talent. Four watches all featuring a pink gold case, a chocolate brown or ruthenium-coated dial, as well as exceptional movements.

Master Minute Repeater
First presented in 2005, the Master Minute Repeater immediately found its place at the very pinnacle of existing minute repeater models. It owes this reputation first and foremost to the purity, the richness and the exceptional sone or volume of its tone: over 55 decibels, a duration of more than 600 milli-seconds and a richness of 7 partial overtones. Moreover, this unique acoustic quality, achieved in particular by a tiny stud or heel directly welded to the sapphire crystal and which therefore acts like a soundboard, is matched by performances that are truly remarkable for a Minute Repeater watch: a 15-day (360-hour) power reserve, water resistance to 50 metres – an unprecedented feat for such a watch – and successful submission to the 1000 Hours test procedure, the extremely rigorous “torture” session that all Master Control models, however complex, must endure.
This creation stems from intense cooperation between the different professions within the Manufacture. The varied skills have been pooled to entirely redesign the mechanical technology of the repeater by associating it with the latest acoustic research as well as the resources afforded by design and exterior features. The result is a model providing generous views of the intricate mechanism within through three openings: one at 12 o’clock revealing the “snails component” serving to engage the quarter and minute gear trains when the minute repeater is activated, the minute rack and the quarter mechanism; another at 9 o’clock showing the striking mechanism barrel and the regulator; and a third at 3 o’clock displaying the work of the hour and minute hammers on the quarter banking.
For its 175th anniversary special edition, the Master Minute Repeater appears in this version unveiling the entire ruthenium-coated movement, surrounded by a bezel ring in the same colour. The square-section gongs are made from a top-secret material which contributes to the acoustic performances of this exceptional watch. The gilded resonance stud is engraved with the founding date of the Manufacture, 1833. Pink gold hands point to the hours and minutes, the power reserve at 8 o’clock and the torque indication for the two barrels at 4 o’clock. The 18-carat pink gold case, fitted with a matt chocolate-coloured alligator leather strap, further enhances the beauty of this truly exceptional model issued in a limited edition of 175.

Master Eight Days Perpetual SQ
Exceptionally housed in a pink gold case, the 175th anniversary special edition of the Master Eight Days Perpetual is mysterious, intriguing and downright superb. The only perpetual calendar with an 8-day power reserve, this collector’s piece rises brilliantly to a range of technical and aesthetic challenges.
Its openworking meticulously follows the constraints imposed by the creative motif which is the very emblem of this model: the planisphere. As one would expect, this planisphere motif, which accentuates the universal nature of this timepiece, determines the entire architecture of the movement and is reflected on both sides of the watch. The balance plays the role of the earth’s pole, while the lines radiating from it are reminiscent of those representing longitude and latitude. This skeletonised craftsmanship creates a decorative effect made up of superimposed and transparent effects, in which the movement appear like islands and continents of various shapes and sizes. Extreme care has been lavished on every detail: the flanks of the planisphere are drawn out with a file, the sinks are polished, the bevelling is performed by hand, while star-studded and sunburst motifs compose a miniature universe embodying a superlative and harmonious decorative whole.
Another challenge lay in displaying the many perpetual calendar indications in such a way that they would be immediately visible while not spoiling the transparency of the ruthenium-treated skeletonised movement. The hours and minutes are indicated by two openworked hands, the power-reserve and moon-phase displays feature two tiny arrows, while the other indications take the form of transparent pivoting discs which – by contrast when crossing through a light-coloured sector – provide simple and instant read-off of the value displayed: date, day of the week, month, year, day/night.

Master Grand Tourbillon
Pure, understated and refined, this timepiece brilliantly associates the time-honoured tourbillon mechanism with one of the sophisticated technical accomplishments that have earned Jaeger-LeCoultre its enviable reputation: the home time/travel time principle. The 24-hour subdial in the upper part of the dial may be used at any time as a second time zone. Local time can thus be read off in the centre and adjusted either forwards or backwards in one-hour increments, while driving the date display accordingly. The latter is indicated by a hand moving around the bezel ring and jumping automatically between the 15th and 16th of each month so as not to spoil the view of the tourbillon carriage.
This tourbillon, endowed with a feather-light (0.28-gram) carriage made from a special titanium alloy, and a cambered escapement bridge that moulds its shape, performs one complete turn per minute. The seconds are shown by a hand with three arms, including an arrow-tipped one, moving across a graduated scale surrounding the tourbillon opening.
Everything conspires to ensure the sturdiness and reliability of this high-precision tourbillon: a balance with an inertia of 11.5 mg x cm2, the automatic 28,800 v/h movement, the adjustment screws placed around balance rim to ensure a constant rate that is undisturbed by impacts, as well as reduced friction and regular transmission of the force by means of spyr-shaped teeth, a compact lever and automatic winding in a single direction.
Visible through the sapphire crystal, the movement decoration with its hand-crafted bevelling, snailing, circular-graining and buffing sets the crowning touch to this genuine work of art, issued in a limited anniversary edition of 575.

Master Ultra Thin
Finally, this fine watchmaking collection created to mark the Manufacture’s 175th anniversary also comprises a limited edition of the extremely pure and beautiful Master Ultra Thin, in a pink gold case and chocolate-coloured dial version powered by manually-wound ultra-thin Jaeger-LeCoultre Calibre 849 and presented in a 38 mm diameter, fitted with a matt chestnut brown alligator strap.
