COMPLICATION VALLEY
When the first LeCoultre arrived in the Vallée de Joux in 1559, he discovered a wild region well off the beaten track of existing trade routes and distinguished by a harsh climate, an unyielding soil as well as extremely rigorous winters. But iron mines had been discovered there and metallurgy was an established activity. Isolated in the silence of their long winters, the blacksmith-farmers of that period had to produce everything themselves, including their own tools. Little by little, they became experts in the field, learned to forge ever slenderer and ever more sophisticated objects.
In 1740, the first watchmaker originating from the valley, who had set off to learn his trade on the shores of Lake Léman, returned to set up his own workshop. Watchmaking began to boom and very soon, under the impetus of pioneers such as the LeCoultre, Piguet, Aubert and Audemars families, the Vallée de Joux came to specialise in the most complex form of the watchmaking art. A close-knit network of expertise and rare crafts began to take shape. The Vallée de Joux became Complication Valley, giving rise to almost all the Grande Complication models of the 19th century.
It was within this context that in 1833 Antoine LeCoultre created his own workshop, which became the leading Manufacture in the region as of 1866. By 1888, almost 500 people were working there, and the Manufacture became known to the inhabitants of the Vallée de Joux as the “Grande Maison”.
By bringing every skill under a single roof, in thereby sharing the various manufacturing secrets and by inventing the first precision machines (the very first being the pinion-cutting machine), Antoine LeCoultre played a pioneering role and laid the foundations of the modern Manufacture. Man and machine were united for the very first time, and the production of complications was enriched by the mechanical precision that had hitherto been lacking. In 1870, the “Grande Maison” became the first Manufacture to produce complicated watches from machine-made parts. Since its beginnings, Jaeger-LeCoultre has conceived and created at least 500 calibres with complications, more than 200 of which are with minute repeaters (the smallest being one of 9 lines, that’s 20.8 mm in diameter) and more than 190 chronograph movements.
From 1890 onwards, the “Grande Maison” began producing Grande Complication and Perpetual Calendar watches, an Alarm movement as of 1929 and Tourbillons from 1946.
Today, over one thousand people work at the Manufacture Jaeger-LeCoultre, daily perpetuating and renewing this noble tradition in the exact same spot as 176 years ago, surrounded by the same natural scenery at the heart of the same valley that more than ever deserves the name of Complication Valley.

New Line
MASTER GRANDE TRADITION
Perpetuating the fine watchmaking tradition of the “Grande Maison” while constantly renewing it: such is the dual principle embodied by the new Master Grande Tradition line.
Its birth testifies to the absolute continuity of the exquisitely refined manual expertise of Jaeger-LeCoultre as well as displaying its superlative technical mastery, its inventiveness and its innovative strength.
The new Master Grande Tradition line is entirely dedicated to watches with double complications featuring a combination of complicated functions that is unique for Jaeger-LeCoultre. While their pure dials and refined exterior are glowing tributes to the grand classical watchmaking tradition, their degree of technical performance, and in particular the use of high-tech materials, enables them to achieve a superior level of precision that is particularly favoured by an innovative silicon escapement.
This two-fold nature – achieving a superior level of mechan-ical precision while featuring fine traditional finishes and prestigious decorations – constitutes the great strength of this new line distinguished by a style and an identity that are doubtless unique within the range of watches currently available on the market. The two new combined functions introducing this exceptional function are driven by two new movements: Jaeger-LeCoultre Calibre 987, associating a tourbillon with a perpetual calendar; and Jaeger-LeCoultre Calibre 947 R which sets out the minute repeater displays in the style of a regulator. These two combinations are a first for Jaeger-LeCoultre and each comprises over 400 parts. The complexity of these movements is such that each watch must be entirely assembled, adjusted and cased up by a single watchmaker.

A refined exterior
As its name implies, everything involved in creating the Master Grande Tradition line is treated with great refinement and respect for the values of fine traditional watchmaking.
The new round case, inspired by the Master case but made exclusively from precious materials, is characterised by pure, finely balanced proportions and highly sophisticated finishes. The polished rounded bezel accentuates this traditional horological appearance of the model and contrasts with the horizontal fine-brushed sides of the case, the polished tops of the lugs and the finely fluted motif on the polished crown.
This perfectly balanced case frames a dial conveying a style inherent to the line. The traditional velvet finish is partially enhanced by a fine Clou de Paris hobnail motif. The classic dauphine hands point towards gilt hour-markers. These exquisitely finished dials reflect an obvious concern for tradition allied with a resolutely contemporary originality. Pure, understated design, perfect symmetry and aesthetic equilibrium which, above and beyond their traditional beauty, ensure excellent readability of the functions.
The movement is decorated with the same uncompromising care for details. The surfaces of the various elements feature a range of finishes including Clou de Paris hobnail motif, double “côtes soleillées”, double snailing, circular-graining or satin-brushed finishes. All the steel parts are hand polished and bevelled. The edges of the bridges and the mainplate of the Master Grande Tradition à Répétition Minutes, made from non-treated nickel silver, are hand-drawn with a file and their angles are raised and polished by hand, while the adjustment screws are blued and the chaton screws are rhodium-plated.
The gold parts of the movement are engraved and the 22-carat gold oscillating weight is decorated with a Clou de Paris motif.
This set of precious treatments powerfully highlights the graphic and architectural splendour of these extremely beautiful movements. In the yellow gold limited series, one can admire the details through the sapphire crystal case-back incorporating a highly original magnifying glass offering an enlarged view of the silicon escapement.
It took the entire range of rare crafts exercised within the “Grande Maison” to attain this degree of refinement and mastery.

Limited editions in yellow gold with a silicon heart
In their two yellow gold limited editions, the two new Master Grande Tradition calibres are equipped with an innovative escapement with a silicon wheel and lever. In order to achieve peerless resistance to wear and shocks, as well as an optimal friction coefficient, the silicon is coated with a layer of diamonds, then polished by plasma to obtain a nanocrystalline structure. The efficiency of the movement is thus enhanced by 15%. Featuring an all-of-a-piece construction – with the lever and pallets integrated within the same ultra-accurate geometry – this ultra-light escapement serves to achieve enhanced inertia and thus improved efficiency further optimised by the reduction of friction.
Their high rating precision, their isochronism and their resistance are controlled by a series of tests specially developed for the occasion. In addition to the famous “1000 Hours Control” test to which all finished and cased-up Master watches are submitted (tests relating to precision, water resistance, shock resistance and variations in temperature, simulation of wearing conditions), an extremely stringent chronometry or timekeeping test, the “1000 Hours Chrono” test, has been introduced. Contrary to the one performed by the COSC, it is also carried out on a complete movement fitted with its complications and cased-up, thereby guaranteeing improved testing reliability.

Master Grande Tradition Tourbillon à Quantième Perpétuel
The new Jaeger-LeCoultre Calibre 987 driving the Master Grande Tradition Tourbillon à Quantième Perpétuel features a luminous and ultra-legible arrangement of the perpetual calendar indications around an especially airy tourbillon design.
The split-level dial construction provides an optimal view of the tourbillon, positioned on a slightly lower level beneath an elegantly slender bridge. This tourbillon equipped with a large variable-inertia, high-frequency balance (28,800 vph) – a token of high precision in its own right – is equipped with an ultra-light grade 5 titanium carriage composed of 78 parts. Regulating screws arranged around the rim and a compact lever guarantee constant, shock-proof rating and considerable energy saving, since the escapement wheel is closer to the centre of the tourbillon.
This tourbillon escapement is teamed with the perpetual calendar mechanism, a sophisticated feat of construction and miniaturisation.
Its several hundred wheels, gears, levers and pivots endow it with a mechanical “memory” of 1,461 days, powering pointer-type indications of the date, month, day and moon phase, along with a year window, while automatically taking account of the length of months and the four-yearly return of leap years.
Driven by the energy produced by a lubricant-free unidirectional winding system (faster and more efficient than bidirectional winding), the Master Grande Tradition Tourbillon à Quantième Perpétuel is available in pink gold, platinum, or in a yellow gold limited edition of 300.

Master Grande Tradition à Répétition Minutes
The Jaeger-LeCoultre Calibre 947 minute repeater mechanism, presented in 2005, had already marked a new era in the domain of sound, thanks to its unprecedented gong heel directly welded to the sapphire crystal. Following on from this improvement in the performances and the celerity of the sound emitted, other innovations have been made, such as the progressive square section of the gongs designed to increase the duration and volume of the sound, or the monobloc construction of the gong and its heel in order to enhance the sound transmission.
The new Master Grande Tradition à Répétition Minutes combines these technical breakthroughs with an all-new regulator display. All watch enthusiasts are acquainted with the tradition of extreme precision inherent to regulators, a term formerly used to refer to the clock that served as a reference in watchmaking workshops.
Its principle is based on disconnecting all the indications from each other. Thanks to this system in which the various hands are not coaxial but instead separate, which means the arbors are not liable to knock into each other, friction is thus reduced and precision is naturally improved.
This precision time read-off is taken a step further with the addition of a small seconds at 6 o’clock, a barrel torque indicator at 4.30 beneath a double aperture revealing the work of the hammers; and a power-reserve indication at 7.30. The latter is indeed amazing: two full weeks of autonomy ensured by just a straightforward hand-winding operation.
On the back, a sapphire crystal pane with integrated magnifying glass enables the observer to plunge into the very heart of the silicon escapement.
A masterpiece issued in 18-carat yellow gold in a limited series of 100.

Rare Crafts
ENAMELLING MASTERS
Enamelling is an incomparably delicate decorative art that first emerged in the late 15th century.
Enamel is a material which, when placed on a metal plate and heated to a high temperature (of between 800 and 1200 degrees Celsius), melts, vitrifies and becomes extremely stable and resistant. Known as Grand Feu enamel, it is applied in thin layers and polished, resulting in dials of a particularly pure, luminous white. They can be hand-painted with motifs, miniatures, numerals or indications. On so-called “flinqué” dials, an opaline enamel covers the engraved or guilloché metal surface.
Coloured enamels are obtained by adding various metal oxides. These splendid shades of enamel are applied to the metal using a goose feather or a fine brush. After firing in the kiln, the operation is repeated as often as necessary to reach exactly the right colour.
Throughout its long history, Jaeger-LeCoultre has not only managed to preserve the secrets of this rare profession but, under the impetus of the Master-Enameller Miklos Merczel, has sought to further develop its subtleties by developing new procedures and creating new particularly translucent pigments. Enamelling is an art in which the human hand and the constancy of the gesture are just as important as technical mastery. When combined with fine watchmaking, it also implies compliance with extremely low tolerances (around 2/10ths of a millimetre) in order to guarantee the smooth running of the watch.
In 2009, which Jaeger-LeCoultre has proclaimed the “Year of enamel”, the brand is presenting a stunning array of exceptional creations.
Among them is the Master Grand Tourbillon Continents, which most strikingly embodies the merging of fine watchmaking and rare crafts practiced by Jaeger-LeCoultre.
A traditional watchmaking theme, the Continents motif is interpreted here in three versions: Asia and Australia – Europe, Africa and the Middle East – The Americas. Each is offered in three limited series of 20 in platinum, 18-carat pink or yellow gold.
So as to provide a particularly vivid and contrasted vision of the outline of the continents, as well as the countries composing them and the oceans surrounding them, the plates of the gold dial are first engraved with sunburst guilloché motifs radiating towards four points of the compass for the continents, and in the form of mini-waves, for the oceans. This magnificently engraved base forms a subtle background beneath the translucent layers of cloisonné enamel and lends the colours vibrant density and magnificent depth.
Another exceptional demonstration of artistic mastery applied to fine watchmaking is the Master Répétition Minutes Venus. Sublimating the art of miniature enamel painting, the four versions of the “Venus” reinterpret four historical masterpieces in the field of classical painting: ‘The Birth of Venus’ by Botticelli; ‘The Venus of Urbino’ by Titien; the ‘Rokeby Venus’ by Vélasquez and ‘Venus Rising from the Sea’ by Ingres.
The four unique works of art are meticulously hand-crafted by the artistic artisans of the “Grande Maison” and framed by the Master Minute Repeater case in pink gold or platinum. The infinite visual pleasure they procure is complemented by the crystal-clear sound of the famous Jaeger-LeCoultre Calibre 947 minute repeater movement housed inside.

Icon
GRANDE REVERSO
The Reverso is already “grand” in several different ways, including by its reputation that has endured for over 75 years and by its status as an Art Deco emblem and a watchmaking icon. The Reverso is also “grand” in terms of its ability to outlast fashions, to adopt countless different faces, from technical to precious, from complicated to restrained and from classic to sporty – all the while remaining first and foremost a Reverso.
It now also becomes “grand” in terms of size with the launch of the new Grande Reverso.
In the Grande Reverso 976 line, the case features generous dimensions (48.5 mm x 30 mm wide), but is singularly more slender than the previous model.
This new size imbues the Grande Reverso with a more decidedly masculine spirit, while maintaining its stylistic purity and endowing it with a natural elegance in tune with its original essence.
This immediately recognisable elegance and style stem from the horological refinement lavished on creating it. The Grande Reverso is beyond doubt a Reverso, faithfully revisiting each of its signature features. The reversibility, of course, as well as the timeless shape and the graphic design of a dial with a double finish: an outer section that is either satin-brushed, or vertical guilloché in the Grande Reverso 986 Duodate version; and an inner zone adorned with the Clou de Paris hobnail motif, with the two areas delineated by the famous “railtrack” minute scale.

Grande Reverso 976
This classic variation, available in 18-carat pink gold or steel, takes its name from Jaeger-LeCoultre Calibre 976, a mechanical manually-wound movement that displays three key functions on the front: hours (adjustable in step with time zones in one-hour increments), minutes and the traditional small seconds in a rectangular subdial positioned at 6 o’clock.
On the back, a sapphire crystal protects the perfectly finished movement, enabling the owner to admire it and to allow others to do likewise.

Grande Reverso 986 Duodate
Driven by the new mechanical manually-wound Jaeger-LeCoultre Calibre 986, the Grande Reverso 986 Duodate is equipped with two dials. The white dial on the front shows the hours in the main time zone, along with minutes, small seconds and a date window; while the black dial on the back displays the hours and minutes of a reference time zone along with a 24-hour and day/night indicator. One especially remarkable technical feature lies in the fact that a single movement simultaneously drives both dials and that all functions are thus adjustable by a single crown. The Grande Reverso 986 Duodate is available in two limited editions of 1500 in steel and 500 in pink gold.

Master Tourbillon
A BRIDGE BETWEEN TWO ARTS
The Manufacture Jaeger-LeCoultre is synonymous with fine watchmaking in terms of the constant quest for technical performance, reliability, mastery of complications and timekeeping precision. But the “Grande Maison” with its forty professions also shows itself capable of paying tribute to the sheer beauty of time. Or, more exactly, of tactfully and elegantly combining two perfectly complementary skills that it masters in equal measure: the watchmaking art and that of gem-setting.
Through the graphic purity of its perfectly balanced lines and its timelessly contemporary shape, the Master Tourbillon lends itself ideally to the splendour and refinement of a jewellery interpretation.
Its tourbillon movement is set into a shimmering dial in black, grey or white mother-of-pearl, or composed of marquetry-worked mother-of-pearl forming floral motifs, graded shades of colour similar to watercolour paintings, or multicoloured fragments of painted enamel, rimmed by a finely diamond-set bezel.
Above the regulator tourbillon with its carriage completing a one-minute revolution and bearing the seconds hand, a tiny subdial indicates the time in a second time zone on a 24-hour scale.
In its full-pavé version, the Master Grand Tourbillon shines in glorious radiance. Fitted with a crocodile leather strap or an all gem-set white gold bracelet, this 43 mm-diameter model is a truly exceptional creation.

Reverso Squadra Lady Duetto
A VERSATILE GEM
In 2008, Jaeger-LeCoultre presented its new Reverso Squadra Lady Duetto. An immediate hit with women, this genuine Art Deco icon with a reversible square case exuding a more casually contemporary appeal than the traditional rectangular Reverso, has been given an additional touch of sophistication and glamour this year.
In the new Haute Joaillerie version, powered by the same Jaeger-LeCoultre Calibre 968, but without a date display, the Reverso Squadra Lady Duetto combines jewellery sophistication with impressively powerful shapes. Its twin faces shine with an even more precious glow. Composed of a marquetry-work composition of radiating motifs, its new front dial is crafted from white mother-of-pearl. The 18-carat white or pink gold case is entirely set with brilliant-cut diamonds, gems echoed in the form of tiny hour-markers on both its dials. Its folding clasp enables fine adjustment of its crocodile leather strap.
This authentic “watch gem” with its incredibly versatile nature matches the rich diversity of activities characterising the lives of contemporary women. Without the need for any tool whatsoever, an ingenious system serves to smoothly interchange the various wristbands available: leather (calfskin, alligator, python), articulated rubber or metal (pink gold or steel). The wristband is released by simply moving two discreet safety pushpieces, and another can be inserted by just snapping it onto the case.
The principle of interchangeability is taken even further, in that the folding clasp on the leather straps requires only three small operations in order to be fitted on another type of wristband.
A remarkable quick-change artist, the Reverso Squadra Lady Duetto can be matched and adjusted to every new professional, sporting or social occasion.

Master Compressor Diving GMT Lady Ceramique
AN ULTRA-FEMININE INSTRUMENT
When the two apparently very different worlds of technique and glamour meet and mingle, the stunning result is called Master Compressor Diving GMT Lady Céramique: a professional sports instrument endowed with the technical sophistication inherent to the Manufacture and at the same time an ultra-feminine, extremely elegant, refined and precious model.
The Master Compressor Diving GMT Lady Céramique owes its dual nature to the use of ceramics for the case – a first in this collection. This stable material is highly resistant – particularly to scratching – while radiating a rare breed of elegance. Both thinner (13.27 mm compared with 14.05 mm) and wider (39 mm compared with 38 mm) than its steel “sister”, the Master Compressor Diving GMT Lady Céramique offers a distinctive play on associations between black, white and silvered shades: a black guilloché dial with applied metallic hour-markers and numerals; a 24-hour dual time-zone display with a windrose-style day/night indication; a movement operating indicator at 6 o’clock in the form of three apertures revealing a two-tone black and white seconds disc; a large date window at 3 o’clock; and a unidirectional rotating bezel in a precious lacquer set with 16 full-cut diamonds.
Nonetheless, this graphic, refined and exquisitely feminine watch is also a high-tech instrument that meets the strict NIHS norms for diver’s watches. At its heart beats the ultra-reliable and accurate mechanical automatic Jaeger-LeCoultre Calibre 971D, beautifully decorated by hand. It is protected by a screw-down sapphire crystal back that guarantees water resistance to 100 metres. It is naturally fitted with the famous compression key crown, the signature feature of the Master Compressor line. The uncompromising readability of the indications is ensured by luminescent hands, a movement operating indicator, and a triangular index on the rotating bezel equipped with a system preventing any accidental rotation.
Fitted on its black articulated rubber wristband master-moulded on a metal base, the Master Compressor Diving GMT Lady Céramique makes a smooth and uncompromising transition from the underwater world to glamorous evenings, as circumstances dictate.

Master Compressor Diving Navy SEALs
PROFESSIONAL DEMANDS
In 1959, Jaeger-LeCoultre made its mark on the history of underwater exploration with the Memovox Deep Sea, the first diver’s watch equipped with an alarm, and also housing the first automatic alarm movement in watchmaking history. Its essential function was to provide the diver with an audible indication that it is time to start returning to the surface.
The Memovox Polaris launched in 1965 took the concept even further. Water-resistant to 200 metres, its triple case-back considerably optimised the quality of the sound and its generous size of 42mm, truly exceptional for the era, facilitated read-off of its indications. Last year, Jaeger-LeCoultre paid tribute to this legendary instrument by launching two separate re-editions, one faithful to the original Memovox Polaris, and the other echoing the famous 1968 model.
However, it was in 2007 that Jaeger-LeCoultre had fully renewed ties with its own history by once again releasing a new line of authentic professional diving instruments, the Master Compressor Diving Pro Geographic, GMT and Chronograph. One particular innovation had an especially strong impact: the membrane-based mechanical depth gauge presented on this occasion.
A further step towards the most demanding professionalism was taken with the agreement signed between Jaeger-LeCoultre and the Navy SEALs, the famous US Navy special forces combat divers unit.
An acronym of SEa, Air and Land, this exceptional military corps which also stands for a legendary aquatic animal, boasts a history dating back to the first group of volunteers selected from the Seabee (CB or Construction Battalion) in the spring of 1943. A new collection of excellent technical instruments has been developed in partnership with this elite corps distinguished by its cutting-edge equipment and its missions conducted in the most demanding conditions and the most extreme aquatic settings.
The Master Compressor Diving Navy SEALs line meets the draconian standards of reliability, performance and resistance demanded by the extraordinary divers and athletes composing this unit, whose emblem is an eagle holding a trident, a rifle and an anchor. This emblem is engraved on the back of each of the three exceptional professional instruments composing this new line.
Master Compressor Diving Pro Geographic Navy SEALs, Master Compressor Diving Chronograph GMT Navy SEALs and Master Compressor Diving Alarm Navy SEALs share a number of essential characteristics: an ultra-resistant case able to withstand strong pressure; a sapphire-blasted ceramic bezel; extreme water resistance extending to a minimum of 300 metres and a maximum of 1000 metres; a leather strap fitted to the watch as the primary option, along with a “Nato” type black Cordura strap with rip-and-grip strip; and the same technical appearance with a black dial featuring luminescent struck numerals and hour-markers.
But above and beyond these common features, each of these professional instruments offers a different function, designed to help divers during their immersions: a depth gauge, chronograph functions, or an alarm.

Master Compressor Diving Pro Geographic Navy SEALs
In 2007, the Master Compressor Diving Pro Geographic had revolutionised the world of scuba diving with a membrane-based depth gauge that gave the case its distinctive profile.
With this new Navy SEALs limited version of 300 in pink gold, water- resistant to 300 metres, Jaeger-LeCoultre once again asserts the exceptional nature of its mechanical depth gauge system which comes clothed for the very first time in a noble metal. A technical instrument by definition, this timepiece keeps step with the diver’s activities by providing a constant and instantaneous indication of depth.
Housed in a chamber on the outside of the case, this ingenious device developed by the engineers of the Manufacture Jaeger-LeCoultre offers the advantage of eliminating any danger of clogging, while the absence of joints guarantees perfect long-term reliability. Technically speaking, the depth gauge membrane, sensitive to the aquatic pressure exercised on its metal head, transmits the information to a rack which transmits it in turn to a red arrow-shaped hand pointing to a highly readable logarithmic scale, more detailed on the first 40 metres and arranged around the outer dial ring.
The imposingly sized 46.3 mm-diameter Master Compressor Diving Pro Geographic Navy SEALs also indicates the date, presents the Worldtime function as well as a movement operating indicator. One need only position the city emblematic of any particular time zone in its dedicated aperture at 6 o’clock for the time to be immediately displayed on a 24-hour subdial located at 9 o’clock. Its precision is guaranteed by the automatic winding movement, Jaeger-LeCoultre Calibre 979, beating at 28,800 vibrations per hour and endowed with a 48-hour power reserve. It brilliantly opts for maximum readability thanks to a play of black, white and silver shades appearing beneath its cambered sapphire crystal (hardness no. 9), along with luminescent hands and indications. The crowns fitted with black rubber master-moulded compression keys, along with the black PVD-coated steel sensor, reinforce the understated elegance of the design.

Master Compressor Diving Chronograph GMT Navy SEALs
This is an authentically technical, demanding and rare diving instrument. Rare because very few watches combine chronograph functions and a dual time-zone display with day/night indication – especially within the context of a diver’s watch that strictly complies with the stringent NIHS (norms relating to its anti-magnetic, photo-luminescent, water- and shock-resistance properties). Indeed, these standards are even surpassed by the Master Compressor Diving Chronograph GMT Navy SEALs, which is watertight to a depth of 100 metres, whereas the NIHS calls for “just” 100 metres.
This 1000-metre performance is achieved by the limited series of 1500 in grade 5 titanium of the Master Compressor Diving Chronograph GMT Navy SEALs, while the 18-carat pink gold version in a limited edition can descend to 300 metres – an impressive record for this precious metal.
A new mechanical automatic movement, Jaeger-LeCoultre Calibre 757, powers this demanding 46.3 mm-diameter instrument complete with a steel-frame ceramic diving bezel, compression key crown and pushpieces equipped with compression wing-nuts and master- moulded in black rubber; as well as a cambered sapphire crystal (hardness no. 9) and screw-down case-back engraved with the Navy SEALs emblem.
The functions are arranged in a powerful, ultra-legible manner on its black dial stamped with luminescent numerals and hour-markers. Two trapeze-shaped skeletonized and luminescent hands point to the hours and minutes. The chronograph functions are indicated by two central hour and seconds hands along with a 30-minute counter, while the dial also shows the date, a movement operating indicator on a luminescent black and white disc, as well as a 12-hour dual time-zone display with complementary day/night indication.

Master Compressor Diving Alarm Navy SEALs
Issued in a limited series of 1500 and presented in a 44 mm diameter that is slightly smaller than the other Navy SEALs watches, the Master Compressor Diving Alarm Navy SEALs reinterprets the historical tradition of the diving watches created by Jaeger-LeCoultre in the 1950s, the famous Memovox watches – the first diver’s watches equipped with an alarm.
Powered by a mechanical Jaeger-LeCoultre Calibre 956 movement featuring the famous hanging-gong striking mechanism as well as the Manufacture’s latest breakthrough developments in terms of automatic winding (a ceramic ball-bearing mechanism requiring no maintenance and no lubrication) and of adjustment (a variable-inertia balance), the Master Compressor Diving Alarm Navy SEALs is equipped with a grade 5 titanium case water-resistant to a depth of 300 metres, along with a steel-frame ceramic diving bezel.

Master Compressor Extreme W-Alarm tides of time
TIDES OF TIME & THE WORLD HERITAGE MARINE CENTER
The magnificently protected environment of the Vallée de Joux where the Manufacture can be found since its inception, made Jaeger-LeCoultre quickly aware of the necessity to actively combat the menace facing the planet and elaborate a global strategy of both local and international actions aptly named “Making Time More Beautiful”.
It is within this context that Jaeger-LeCoultre has entered into a three-year partnership with UNESCO and the International Herald Tribune, in order to lend its support to the essential international programme of protection and enhancement of marine sites conducted by the UNESCO World Heritage Marine Centre. This partnership aims to preserve these marine sites by appropriate conservation and management oper-ations, thanks to the concrete help provided by Jaeger-LeCoultre. In addition to making a direct financial donation, Jaeger-LeCoultre is also sponsoring the publication of the “Tides of Time” pages in the International Herald Tribune, which will be dedicated to 24 marine sites around the world. This operation represents an effective means of alerting public opinion and of raising additional funds.
As a concrete expression of this major partnership with UNESCO and to ensure its active promotion, the Manufacture is presenting two special “Tides of Time” editions of its spectacular Master Compressor Extreme W-Alarm model. Combining the Worldtime system, a highly readable Memovox alarm function and the remarkable technical and water-resistance properties of the Master Compressor Extreme line (shock-absorbing system, compression keys, interchangeable wristband), the “Tides of Time” special edition is limited to 200 in pink gold and titanium and 350 in grade 5 titanium. Its dedicated dial highlights three of the 24 sites (Scandola, Galapagos and Tubbataha) that require immediate protection.

Atmos Birth Date
VIRTUALLY ETERNAL
The Atmos clock by Jaeger-LeCoultre, an iconic product by the Manufacture for the past 80 years, is the single object in the world that comes closest to attaining the myth of perpetual motion.
Imagine for just a moment: its movement requires so little energy that it would take 60 million Atmos clocks to light up a single 15-watt light-bulb! The lowest energy-consuming mechanical system ever invented by humankind, the Atmos mechanism runs in step with infinitely small changes in temperature. A difference of just one degree modifies the volume of gas enclosed within a water-resistant accordion-type bellows system that dilates and contracts to wind the barrel. The latter in turn drives the clock mechanism for a full 48 hours. Simply open or close a window or a door, and you will have gained entire days of autonomy.
As the official gift of the Swiss Federal government to its foreign guests, the Atmos has found its place in the offices of Sir Winston Churchill, JF Kennedy, General de Gaulle and King Juan Carlos, to mention just a few of its famous owners.
What could be more appropriate to celebrate the birth of a new human being than to gift an Atmos clock? The Atmos Birth Date is the name of the new collection of clocks clothed in blue or pink. This “virtually eternal” timepiece can be personalised by the inscription of the date of birth subtly integrated into the month display, and by its owner’s name engraved on the base.
This exceptional creation, powered by a unique and almost perpetual technical and horological soul, features craftsmanship designed to stand the test of time.
