Invention through movement – Master Compressor Extreme LAB 2

In the Joux Valley, the term “invention” conveys particularly strong significance. In order to transform this remote region perched at an altitude of 1000 metres into the high place of horological complications, its inhabitants have had to draw upon the only abundantly available resources: time, intelligence, and manual dexterity. The founder of Jaeger-LeCoultre, Antoine LeCoultre (1803-1881) is one of the greatest watchmaking inventors. His decision to unite all the diverse horological skills under one roof stemmed from his keen awareness that only such a pooling of talent, imagination and passion could enable him to fulfil the most ambitous mechanical challenges.
Since 1833, the quest for reliability, precision, ergonomy and new functions has thus been expressed at Jaeger-LeCoultre by the filing of more than 350 patents and the creation of 1000 different mechanical calibres, including 500 equipped with complications.
Since the year 2000, the Manufacture has literally revolutionised the main classic complications: the most accurate tourbillon in the watch industry has turned spherical and been equipped with a cylindrical balance-spring; the most complete perpetual calendar has been interpreted on the first ever watch with three dials powered by a single movement; the chronograph has been treated to its own independent gear train, free of any coupling-clutch; and finally, the history of repeater watches has been enriched with the longest-sounding Westminster chime. More than ever, in 2010 Jaeger-LeCoultre is characterised by the theme of inventions. The first chronograph created for extreme conditions, resulting from more than 22,000 hours of development and the combined expertise of experienced physicists, the Master Compressor Extreme LAB 2 embodies a full range of superlative technical performances and horological sophistication. The Master Grande Tradition Grande Complication sets the scene for the first tourbillon gravitating around the dial to the tune of sidereal time, along with a minute repeater featuring a sound enhanced by hammers articulated like medieval catapults, or trebuchets. Meanwhile, the Duomètre à Quantième Lunaire is the first mechanical watch equipped with sixth-of-a-second time-setting.
At Jaeger-LeCoultre, each watch has its own dedicated calibre, designed and developed specifically for this particular model. The 1000 or so people working within the sprawling premises of the “Grande Maison” in the Joux Valley simultaneously produce over 60 different movements, from the smallest in the world to the most complicated, as well as ultra-thin calibres and the perpetual mechanisms driving the Atmos clock. To create such mechanical marvels, the Manufacture has added a whole new building, as of this year providing more than 9000m2 of additional workshop space enabling the company’s watchmakers, artisans, technicians and artists to perpetuate the grand tradition and to scale new technical peaks of achievement.

In 2010, Jaeger-LeCoultre is taking a new step in its conquest of sports-oriented horological complications by introducing the Master Compressor Extreme LAB 2 Tribute to Geophysic, representing the culmination of all the brand’s previous innovations, enriched with a new characteristic: anti-magnetism. In 1958, on the occasion of the International Geophysical Year, Jaeger-LeCoultre first launched its Geophysic Chronometer, an anti-magnetic watch – magnetism being a sworn enemy of horological accuracy – which was notably presented to the commander of the Nautilus, an American submarine that became the first to pass under the North Pole.
The movement was protected at the time by a special soft-iron cage, which prevented magnetic fields from affecting the mechanism. The Master Compressor Extreme LAB 2 Tribute to Geophysic features an infinitely more complex and innovative solution. In this model, the movement parts actually protect themselves from magnetism! The organs that are most crucial to precision have been made of amagnetic materials, including the silicon escapement, the movement arbors and the hands. This whole new approach also implied creating an amagnetic titanium case complete with a ceramic bezel and crown.
To gain a deeper understanding of the properties of magnetism and to discover new technical solutions, the Manufacture Jaeger-LeCoultre called upon the expertise of seasoned physicists using cutting-edge scientific instruments.

The new Jaeger-LeCoultre Calibre 781
The all-new Jaeger-LeCoultre Calibre 781 was specifically developed for extreme sports and designed to guarantee excellent readability, optimal user-friendliness, perfect ergo-nomics, peerless precision and the highest possible degree of reliability. Endowed with a 60-hour power reserve, a large variable-inertia balance oscillating at 28,800 vibrations per hour, a column-wheel chronograph mechanism complete with coupling-clutch, a barrel-bridge screwed on both sides, and an oscillating weight mounted on ceramic ball bearings, Jaeger-LeCoultre Calibre 781 is a new base movement that will lend itself in the future to combinations with other horological complications.
Its construction is organised to ensure wearer comfort and easy handling. A function-selector system, displayed on the dial and controlled by a pushpiece integrated within the crown, enables the user to instantaneously opt for winding, time-setting or adjustment of the date and the second time-zone without even needing to pull out the crown. This user-friendliness and legibility are further reinforced by the considerable depth of the dial which enables a natural hierarchical arrangement of the various indications. By way of example, the read-off of the chronograph minutes is facilitated by a digital counter; while the power-reserve is intuitively read off by a 180° radial indicator around the rim of the dial. The chronograph is activated in an equally ergonomic way by means of two broad metal pushpieces coated with a layer of rubber, thus providing a large surface area for an easy grip and protecting the crown from potential impacts. At 9 o’clock, a similarly well-designed ‘trigger’ controls a manual stop seconds function that is separate from the time-setting and thus ensures enhanced precision. Conceived in the same spirit, a secure fast wristband-change system has been developed on the back of the watch. The high-tech wristband itself comprises a fine-adjustment system integrated inside a new double pin buckle.

The Geophysic Expedition conquers a virgin Himalayan peak
In October 2009, three men – elite Swiss mountain guide Stéphane Schaffter; Apa Sherpa, the man with a world-record-winning number of 19 Everest ascensions to his credit; and Little Karim Balti, nicknamed the “King of Karakoram” – took up a rare and extreme challenge: that of conquering one of the world’s few remaining summits. This 6,589 metre-peak now bears the name Mount Antoine-LeCoultre! Four timepieces accompanied them on their adventure: a legendary Geophysic Chronometer from 1958, a Master Compressor Extreme LAB, a Master Compressor Extreme Chronograph and the new Master Compressor Extreme LAB 2. All four are timepieces designed to withstand the toughest conditions and are capable of maintaining perfect reliability and superlative precision despite the hostile environment and extreme weather conditions encountered during this adventurous first ascension.

The Master Compressor Extreme World Chronograph has enjoyed unabated success since its launch in 2005. In 2010, Jaeger-LeCoultre is presenting two new versions of this chronograph, which embody the ultimate sports watch combining a 1/4th of a second chronograph function with a world-time indication.
The two new models in steel and titanium or in pink gold and titanium both feature the same recognisable face for which the previous models were renowned, but the design has been significantly revisited. The bezel is slimmer in order to provide even more space for the chronograph indications displayed on two ultra-legible dials; the hands are facetted; and the dial is made from a new material, texalium – an aluminium-coated woven-glass composite. This treatment gives the dial an elegantly shimmering and tech-look surface ensuring optimal readability of the indications. The latter include the highly original movement operating indicator and the city disc combined with a 24-hour dial ring enabling instant read-off of the various time-zones indicated by a two-arm hand. A tool-free wristband-change system integrated within the case enables the wearer to switch quickly and easily between leather or rubber-moulded straps.
The new Master Compressor Extreme World Chronograph is powered by Jaeger-LeCoultre Calibre 752, an automatic movement protected by the brand’s original air cushion-based shock-absorbing system. With its vertical coupling clutch, its large variable-inertia balance and its laser-welded balance-spring, Jaeger-LeCoultre Calibre 752 boasts the full measure of reliability, precision and endurance one would expect from a great sports model.

In 2009, Jaeger-LeCoultre presented three limited-edition models in the Master Compressor Diving Navy SEALs line: the Alarm, Chronograph GMT and Pro Geographic watches (the latter being immediately recognisable by its mechanical depth gauge). Developed in partnership with the elite US Navy special forces unit, the Navy SEALs, these timepieces are directly inspired by the equipment of these exceptional swimmers and athletes, and meet the most stringent criteria of reliability, performance and resistance demanded by extreme conditions of wear. In 2010, the Manufacture is presenting a new model with a smaller diameter (42 mm compared with 44 or 46.3 mm), but endowed with all the main characteristics of the Navy SEALs collection: a compression key ensuring maximum water resistance; a ceramic bezel that is both watertight and scratchproof; oversized numerals and hour-markers for enhanced readability; as well as a range of rubber-moulded or articulated straps in rubber or leather. The Master Compressor Diving Automatic Navy SEALs is equipped with an automatic Jaeger-LeCoultre Calibre 899 and issued in a limited edition of 1,500.

A perfect blend of feminine charm and sporting performance, the Master Compressor Diving GMT Lady Céramique is both a jewel-lery watch and a genuine diving instrument meeting the most demanding norms in terms of luminescence, watertightness and shock-resistance. Its automatic Jaeger-LeCoultre Calibre 971D movement beats inside a superb black ceramic case measuring 39 mm in diameter and 13.27 mm thick, equipped with a lacquered pink-gold one-way rotating bezel set with 16 full-cut diamonds. On its black dial, trapeze-shaped hands coated with a white luminescent substance point to the hours and minutes, while the large date is displayed across the arc of a circle and the dual time-zone appears on a 24-hour scale. This refined yet sturdy model comes teamed with a black ceramic wristband, and is also available with a black satin or black articulated rubber strap.

The Master Grande Tradition line enshrines the historical continuity of the noble watchmaking traditions cultivated by the “Grande Maison”, evidenced through the classicism, the purity and the prestige of its exterior, as well as its perpetually inventive spirit. By integrating the ultimate technical and timekeeping performances achieved by the Manufacture Jaeger-LeCoultre, the Master Grande Tradition line associates traditional styling with avant-garde technological solutions in a manner that is doubtless unique in the industry.
After the two first double-complication watches presented in 2009, the Master Grande Tradition Tourbillon à Quantième Perpétuel and the Master Grande Tradition à Répétition Minutes, Jaeger-LeCoultre now presents a triple-complication model, the Master Grande Tradition Grande Complication. This first grand complication in the Master Grande Tradition line is a magnificent demonstration of horological expertise featuring an entirely original combination of a mysterious as well as orbital flying tourbillon, and a minute repeater.
This mysterious tourbillon is integrated within the sky chart and, while spinning on its own axis once a minute, also performs a complete turn of the dial along with the sky chart in exactly 23 hours, 56 minutes and 4 seconds. Meanwhile, a tiny sun rotates around the dial in 24 hours. Each day, the sun moves to another graduation on the scale, thereby indicating the months and the signs of the Zodiac.

Bringing the cosmos to the wrist
In its uniquely poetic manner, the Master Grande Tradition Grande Complication thereby precisely reproduces the movements of the luminaries in the sky above us, providing a vivid reminder of the very origins of the calendar. But technically speaking, this wrist-scale representation of the cosmos implies a meticulous and extremely innovative construction. Protected by a sapphire crystal, this miniature cosmos is driven by two different discs rotating on a single axis. The first disc, depicting the sky, is connected to the flying tourbillon and indicates the zodiac chart and the month. Beneath it, a second disc provides a 24-hour indication. The difference in rotation between the two discs, amounting to 3 minutes and 56 seconds, means that each day at noon, the bridge-free flying tourbillon mounted on ceramic ball-bearings and featuring an arm-shaped carriage occupies a different position and thereby indicates true solar time.

Fundamental innovations
The Master Grande Tradition Grande Complication is also a Minute Repeater watch. As such, it houses the latest cutting-edge developments introduced by Jaeger-LeCoultre in one of its favourite fields. Connoisseurs will undoubtedly recall the Master Minute Repeater Antoine LeCoultre introduced in 2005, with its patented characteristic gong-heel welded directly to the sapphire crystal which, thanks to the celerity of the glass which thus serves as a sounding board, considerably increases the power of the sound emitted. The volume of the sound was also improved by the square cross-section of the gongs, and the duration by their progressively tapered shape. Moreover, one of the 13 patents registered for the exceptional Hybris Mechanica à Grande Sonnerie presented by the Grande Maison in 2009 was for the extremely innovative articulated trebuchet hammers that substantially improved the accuracy and force of strike on the gong. All these fundamental innovations in the field of sound now also appear in the Master Grande Tradition Grande Complication.

The new Jaeger-LeCoultre Calibre 945
These key characteristics are incorporated within a new movement comprising over 500 parts, Jaeger-LeCoultre Calibre 945. This original calibre also benefits from the latest developments from the company’s R&D LAB, in terms of precision and an optimised avant-garde silicon escapement that is 15% more efficient than its traditional counterparts. This performance, made possible by the three times lower than usual inertia of the components, is also guaranteed over the long term due to the absence of any lubricant.
Moreover, in addition to the silicon escapement, the flying tourbillon of Jaeger-LeCoultre Calibre 945 also integrates the optimised features of the one equipping the Hybris Mechanica à Grande Sonnerie: an adjustable variable-inertia monometallic large balance with a high frequency of 4 Hz; a grade 5 titanium carriage; a Breguet overcoil balance-spring; and ceramic ball-bearings. This optimisation of the rating precision of Jaeger-LeCoultre Calibre 945 is proven and duly certified by the new “1000 Hours Chrono” label. In addition to a battery of stringent tests of watertightness, shock-resistance, power reserve and running on the wrist, this label also comprises specific tests of precision complying with the strict criteria applied by the Swiss Official Chronometer Testing Institute, the COSC – albeit with one significant exception. Contrary to those performed by the COSC, these tests are conducted on the complete and fully cased-up watch, making the “1000 Hours Chrono” the most demanding label in the Swiss watch industry.
Only 75 of these Master Grande Tradition Grande Complication watches will be crafted, exclusively in 18-carat white gold. Inspired by watchmaking traditions, their extremely elegant 44 mm-diameter, 15.6 mm thick case featuring alternating polished and satin-brushed surfaces was specially designed for this model, and constitutes a stunning example of the harmonious integration of a grand complication movement. The sapphire crystal on the case-back enables one to admire the intricate motion of the trebuchet hammers and to admire the exceptional movement finishing including the surface adorned with double “cÔtes soleillées”, circular graining, double snailing or satin-brushing, polished and bevelled steel parts, blued screws and rhodiumed chatons.
Nonetheless, the most spectacular vision is undoubtedly that of the numeral-free dial face with its slowly rotating central sky chart, along with the mysterious orbit of its flying tourbillon around a silvered and blued ring indicating the hours, months and signs of the Zodiac.

In 2007, Jaeger-LeCoultre launched a new collection based on a genuinely revolutionary concept: the Duomètre line. Its goal was to ensure the best possible chronometric performance while incorporating a complication of which the operation would not interfere with the precision of the movement rating. The solution was unique in its kind: a single regulating organ with two separate barrels supplying energy to two different gear trains. In other words, two distinct mechanisms – one dedicated to indicating the hours and minutes; and the other to driving a complication – yet both synchronised by the same regulating organ. br/> The first application of this brilliant concept was the Duomètre à Chronographe, powered by Jaeger-LeCoultre Calibre 380 and which immediately earned a number of awards. The Grande Maison is now pursuing its efforts in terms of both innovation and chronometric improvement by introducing the Duomètre à Quantième Lunaire, equipped with Jaeger-LeCoultre Calibre 381. The basic operating principle is identical to that of its predecessor, but its application is significantly different. As on the first model, there is just one regulating organ – comprising the balance, wheel and lever – and there are two separate mechanisms. However, the first of these mechanisms, composed of an independent gear train, serves exclusively to transmit to the balance the energy supplied by a first barrel with a 50-hour power reserve.
Thanks to this barrel, the constant-force escapement thus has its own supply of energy that is independent from that supplied to the complication by a second barrel (also en-dowed with a 50-hour power reserve) and driving the hours, minutes, seconds, date and moon-phase indications. The operation of the latter in no way interferes with that of the first barrel, which means that the accuracy of the regulating organ is neither disturbed nor otherwise influenced by the running of the complication.

Superlative precision
The indications of the complication are thus “piloted” by a permanently rotating jumping seconds hand directly linked to the balance wheel. By jumping six times per second, this hand serves to ensure greater accuracy when adjusting the seconds, an operation greatly facilitated by an exclusive Jaeger-LeCoultre mechanism which automatically resets both the jumping seconds and the central seconds hand to zero when the crown is pulled out to the adjustment position. No other watch offers such a guarantee of superlative precision when setting a timepiece. Moreover, the unprecedented design of the Duomètre à Quantième Lunaire makes it the only watch to offer maximum precision of the regulating organ when restarting the movement after setting it to an hour signal.

Dual nature
The dual nature of this watch is perfectly expressed by its dial, which is also clearly divided into two distinct zones. The left shows the moon-phase indication, the pointer-type date display and the power reserve of the escapement barrel. The extremely beautiful moon-phase, as it can be viewed from the Northern hemisphere, appears through a dedicated window, while the state of the moon as seen from the Southern hemisphere is indicated by a double hand pointing to the day of the lunar cycle on one side and the graphic depiction of the phase on the other. Appearing on the right are the indications of the hour, minute, the power reserve for the timekeeping, date and moonphase functions. The visual appeal is further enhanced by a central seconds hand and a small subdial at 6 o’clock with its seconds hand jumping every sixth of a second. Two large openings on either side of the dial enable one to admire the exceptional finishing of the movement in action and to read off the two power-reserve indications directly engraved on the mechanism.
Inspired by the precious pocket-watches and the Grand Complication models created throughout the history of the Grande Maison, the decoration of Jaeger-LeCoultre Calibre 381 displays a superlative level of hand craftsmanship.

Two of the new models in the Master Control line are directly linked to the history of the alarm function, the oldest horological complication and one to which Jaeger-LeCoultre has made a major contribution.
The history of the alarm watch is indeed inextricably entwined with that of Jaeger-LeCoultre itself: from the legendary Calibre 489 Memovox introduced by the Manufacture in 1950, and the first automatic alarm watch also presented in 1950; to the addition of a date two years later; the late 1960s release of Jaeger-LeCoultre Calibre 916 with its high-frequency balance oscillating at 28,800 vibrations per hour; the achievements of the 1980s with the highly exclusive Grand Réveil, the first alarm watch equipped with a perpetual calendar and a bronze gong; the Master Grand Réveil models of the 2000s; and right through to the recent successful re-edition of the vintage-style Memovox Tribute to Polaris.
The Manufacture is now pursuing this magnificent watchmaking adventure by presenting two new alarm watches, the Master Memovox and the Master Memovox International.

Master Memovox
With the soft, elegant lines of its 40 mm pink gold or steel case, its pure, uncluttered silvered dial, its date window at 3 o’clock and its two crowns (one at 2 o’clock to wind and set the alarm and to make rapid date corrections; and the other at 4 o’clock to wind the watch and set the time), the Master Memovox is the most classically understated expression of the watchmaking art. It is driven by an automatic movement, Jaeger-LeCoultre Calibre 956, the latest in a long line of alarm movements from the Manufacture. Its long-term performances are ensured by a variable-inertia large balance, ceramic ball-bearings and a 45-hour power reserve.

Master Memovox International
The limited edition (750 in steel, 250 in pink gold) of the Master Memovox International revives a model first launched in 1958, also known as the Memovox Worldtimer and which was part of the “Jubilee” collection launched to mark Jaeger-LeCoultre’s 125th anniversary. The central alarm disc on its dial displays the name of 24 cities, representing each of the time-zones and enabling the traveller to instantly read off the time around the world as a complement to the ever-useful alarm function.

The classically round and extremely elegant Master Control line epitomises a form of horological expertise entirely dedicated to purity and functionality.
This proud lineage already comprises a number of successful models, including the ultra-classic Master Control, the famous Master Geographic, the extremely complete Master Calendar, the understated Master Hometime with its fast-adjustment travel time-zone display, the uncompromising Master Tourbillon, the finely structured Master Réserve de Marche, and the highly sophisticated Master Ultra Thin.
This prestigious family now welcomes the eagerly anticipated Master Chronograph

Master Chronograph
The chronograph, one of the most sought-after and useful horological functions of all, was still missing from the Master Control range. The new Master Chronograph addresses this pressing demand while embodying the cardinal values of the Master Control line: namely, elegance, readability and purity placed in the service of optimal functionality.
Naturally round, with a 40 mm diameter suited for all wrist sizes, the Master Chronograph comes in a choice of 18-carat pink gold or steel. This new 12.6 mm thick case has been subtly redesigned with slimmer lugs and a narrower bezel providing as much space as possible for the dial with its chronograph displays. The latter are perfectly readable thanks to the large hour and 30-minute counters appearing on the dial at 9 and 3 o’clock respectively, along with small seconds at 6 o’clock and a date window at 4.30. The two central gilded hour and minute hands are complemented by a slender blued central chronograph seconds hand. The elegant silvered dial, which is slightly domed so as to highlight the delicate sunburst decoration, is rimmed by a pulsometric scale providing an additional useful function.
Fitted with a back engraved with the Master Control logo, the case houses Jaeger-LeCoultre Calibre 751 a/1. This automatic vertical coupling-clutch column-wheel chronograph movement, guaranteeing optimal precision of the start/stop function, is particularly sturdy, reliable and accurate thanks to the incorporation of the latest breakthrough features developed by the Manufacture: a high-frequency (28,800 vph) variable-inertia balance and ceramic ball-bearings.

Born alongside polo fields in 1931, with a swivelling case enabling it to withstand the hard knocks sustained in this noble and strenuous sport, the Reverso has become an inescapable watchmaking icon. Its extreme versatility lends it to all kinds of transformations, from the most horologically complex to the most brilliantly sparkling jewellery interpretations – yet without ever losing its remarkable identity, whether expressed in rectangular form or through the square shape of the Reverso Squadra line.
The new Reverso Squadra Chronograph GMT Palermo Open is an extreme watch in all possible respects, representing a stronger than ever expression of the Reverso’s indefectible bonds with its sporting origins. Developed in association with Argentinean polo champion Adolfo Cambiaso, the new model is the first Reverso to be equipped with a rubber-coated case in either steel or pink gold (the latter in a limited edition of 500). The reversibility of the case implied intense research into developing the particular coating and its particularly complex manufacturing process involving high temperatures and strong pressures. This combination of materials, reflected on the dial to ensure enhanced readability, creates an extremely powerful design.
Driven by an automatic movement, Jaeger-LeCoultre Calibre 754 (65-hour power reserve), the Reverso Squadra Chronograph GMT Palermo Open displays the hour, minute and seconds, a large date window, as well as GMT and chronograph functions. It is fitted with an ultra-rugged high-tech fabric strap.

For all women who prefer the comfort of a watch with a movement that is always reliable (apart from the rare occasions when the battery needs to be changed), Jaeger-LeCoultre introduces a new Reverso Squadra Lady equipped with the extremely consistent quartz movement, Jaeger-LeCoultre Calibre 657. Its steel case is enhanced by two rows of diamonds framing an exquisitely refined white marquetry-worked mother-of-pearl dial adorned with floral numerals. The other side of the case provides space for a personalised engraving. The elegant and contemporary Reverso Squadra Lady is also very versatile, with an exclusive system that enables the wearer to switch smoothly from an alligator leather strap to a steel bracelet and thus adapt the watch to all kinds of social or sporting occasions.

The quintessentially classic Reverso Duetto Duo launched in 2006 features twin faces representing daytime and night-time hours. It now appears in steel for the very first time. The daytime side has an ele-gantly understated and classic face with floral nu-merals arranged around its silvered dial. The night-time side is more refined than ever, with 32 diamonds adorning its numeral-free black dial bearing a moon and three stars. Front and back thus combine to offer not only twin faces but also two different time-zone displays. Fitted with a satin or leather strap, the Reverso Duetto Duo is equipped with mechanical manually-wound Jaeger-LeCoultre Calibre 854.

While born under a sports star, the Reverso Squadra brilliantly demonstrates its capacity for radical transformation into an extremely feminine jewellery model. Adorned in diamonds and clothed with precious materials, its square case retains the strength of its bold lines while lending itself to a variety of refined interpretations. Women are naturally drawn to this watch radiating a blend of subtle appeal and distinctive character. The Reverso Squadra also provides Jaeger-LeCoultre with a fascinating field of expression for their exceptional talent.

Reverso Squadra Lady Automatic
A new Reverso Squadra Lady Automatic is enriching this ever more successful collection. With its large floral numerals dancing around a marquetry-worked mother-of-pearl dial framing a delicate day/night indicator, its double row of 36 round diamonds encircling an 18-carat pink gold case, its pink gold bracelet or purple crododile leather strap, the Reverso Squadra Lady Automatic is more powerful and sophisticated than ever. The sapphire crystal on the back reveals the intricate mechanical workings of its new movement, Jaeger-LeCoultre Calibre 967.

Reverso Squadra Lady Duetto Haute Joaillerie
Day and night alternate on the twin faces of the Reverso Squadra Lady Duetto Haute Joaillerie. On the front, a shimmering mother-of-pearl marquetry-work pattern surrounds the sunburst disc of the oscillating weight, while a black mosaic-work motif on the back encircles a day/night indicator depicting a night sky studded with brilliant-cut diamonds. Both sides of this precious case in 18-carat pink or white gold are also paved with round diamonds. Driven by an automatic mechanical movement, Jaeger-LeCoultre Calibre 968, the Reverso Sqaudra Lady Duetto Haute Joaillerie is fitted with a white alligator leather strap or an 18-carat pink or white gold bracelet with diamonds forcefully accentuating its architecture.

Reverso Squadra Lady Art
The Reverso Squadra Lady Art is a spectacular demonstration of jewellers at the peak of their art. The two sides of its case and bezel in white gold and its dial are entirely paved with diamonds and colourful sapphires composing a stunningly poetic and abstract landscape of precious stones. The exceptionally silky-smooth feel of this creation stems from the “snow setting” technique developed by the Manufacture in 2002. The stones of varying dimensions appear to merge into each other, playing on their different diameters, colours and sparkle so as to entirely cover the surface of a watch with a décor that is by nature always one of a kind. Driven by a mechanical automatic movement, Jaeger-LeCoultre Calibre 822, the Reverso Squadra Lady Art also features an ingenious fast strap-change mechanism.

Master Lady Tourbillon “feathers”
The Master Lady Tourbillon “feathers” offers a dazzling association between a major watch complication, the tourbillon, and the exceptionally sophisticated decorative refinement of mother-of-pearl, diamonds and genuine feathers. The lines of the 39 mm case have been subtly redrawn and are accentuated by a row of diamonds, slimmer lugs, a softer bezel and a new crown design.
The Master Lady Tourbillon “feathers”, with its bezel adorned with a circle of diamonds, houses Jaeger-LeCoultre Calibre 978 also featuring a diamond-rimmed tourbillon. This movement drives the indications on an extraordinary Art Deco-inspired dial composed of a geometrical marquetry-work motif composed of brilliant-cut diamonds, mother-of-pearl and genuine feathers. An enchanting sight.

Master Minute Repeater
Uniting fine watchmaking, High Jewellery and the artistic crafts exercised within the Manufacture, the Master Minute Repeater is a single-handed blend of the multiple Jaeger-LeCoultre fields of expertise. It displays innovation not only in terms of watchmaking techniques, but also through the materials that transform the art of jewellery-making. The dials of the Master Minute Repeater are carved from rutile quartz for the pink gold version of this watch, or in tourmaline quartz for the platinum version. These rare forms of quartz endow the openworked dial with a sparkling luminosity admirably revealing some of the key components of the prestigious Jaeger-LeCoultre Calibre 947 driving the hour and minute hands as well as the minute repeater functions. Two segments at 7 and 5 o’clock respectively display the power reserve and the barrel-spring torque.
The 950 platinum version features a bezel set with baguette-cut diamonds, along with diamond-set lugs, while the bezel of the pink gold version is set with round diamonds. Both models are issued in limited editions of 18 each.

The lowest energy-consuming mechanical system ever invented by humankind (you would have to line up 60 million Atmos clocks to light a single 15-watt light bulb), the Atmos clock by Jaeger-LeCoultre is the object that comes closest to the myth of perpetual motion. This is because it operates by means of tiny changes in temperature: a single degree of difference varies the volume of gas enclosed within an airtight “bellows” device, of which one single “breath” (expansion and contraction) is enough to wind the barrel which powers the mechanism for a full 48 hours.
In the course of its history, the Atmos, the perpetual clock that literally “lives on air”, has become famous around the world and has been interpreted through a number of different models ranging from classic to contemporary and from simple to complex, including limited series such as the Atmos Mystérieuse, the Atmos Régulateur or the emblematic Atmos du Millénaire with its dial displaying the years up to the year 3000. In 2010, Jaeger-LeCoultre introduces three new Atmos models: two that project it into the future, and one that pays tribute to its creator.

Atmos 566 by Marc Newson
It is no concidence that a designer such as Marc Newson, whose career has led him to explore all fields of design, from interior decoration to daily objects and furniture, should have spontaneously contacted the Manufacture Jaeger-LeCoultre with a proposal to reinterpret the Atmos in an innovative and completely contemporary manner. Seeking to capture the very essence of this clock, Marc Newson created a pure and transparent work of art for Jaeger-LeCoultre that was presented in 2009. Held within a crystal bubble specially made by the famous Baccarat glass specialist, the Atmos 561 by Marc Newson – named after its new calibre – brilliantly demonstrated the enduring power of this creation.
Its considerable success has duly rewarded the exceptional nature of this astonishing design. In 2010, Jaeger-LeCoultre and Marc Newson are presenting two new Atmos models. The same Baccarat crystal bubble reveals a glimpse of a new movement, Jaeger-LeCoultre Calibre 566 which, in addition to driving the hour and minute hands, also powers displays of the month and the equation of time, along with a splendid view of the sky above the Northern hemisphere complete with indications of the cardinal points and the signs of the Zodiac. Two limited editions of these clocks are available: 48 in white Baccarat crystal and 18 in blue Baccarat crystal.

Atmos Réédition 1930
From the age of 14 onwards, Jean-Léon Reutter attempted to design clocks embodying perpetual motion. Having become an engineer, he established the working principles of a clock able to run for several centuries without any external intervention. But it was not until 1932, after his encounter with Jacques-David LeCoultre, and thanks to the technical and manual resources of the Manufacture, that the optimisation process was completed and series production could begin on what was to become an emblem of Swiss watchmaking. Since then, over 750,000 Atmos clocks have been produced in countless shapes and sizes and materials, but all based on the same fundamental operating principle.
With the Atmos Réédition 1930, Jaeger-LeCoultre pays tribute to this great inventor. A faithful reproduction of one of the very first “perpetual clock” models dating back to 1930, it offers a spectacular demonstration of the incredibly modern character of this avant-garde achievement.
Beneath its bell-shaped glass cabinet, the Atmos appears in all its quintessential horological glory, revealing the interior of its timeless mechanism. This re-edition in steel, glass and air is being issued in a limited edition of just 300.
