Epitomising the Maison’s commitment to watchmaking excellence, the Master Control takes its name from Jaeger-LeCoultre’s 1,000-Hour Control Certification and was the first watch collection to undergo this rigorous testing protocol – not just of the movement, but of the cased-up watch – which has since become standard for all Jaeger-LeCoultre timepieces.

A Refined and Contemporary Aesthetic Inspired by the Maison’s Rich Heritage

With its harmonious proportions and restrained styling, the Master Control collection draws inspiration from the Maison’s emblematic round watches of the 1950s and ’60s, such as the Memovox and Futurematic. The new Master Control Chronograph Calendar with black dial subtly recalls the coloured watch dials of the mid-20^th century, reinterpreting their vintage appeal in confidently contemporary style.

Anchored by the clean, modern lines of the case, myriad refined details highlight the chronograph and calendar displays. The dial is framed by a pulsometric scale marked around the flange (a traditional indication originally developed for physicians to measure patients’ heart rates, and equally relevant for today’s lifestyles), which, in keeping with tradition, is marked in red. Creating a dynamic contrast with the black dial, the red is repeated on each of the three sub-dials and in the day and month windows, drawing the eye to this valuable information.

The indications for the two complications – a complete calendar and a bi-compax chronograph – are balanced in a dial layout that is timeless, straightforward and intuitive to read, despite the complexity of the information shown. The 30-minute chronograph counter at 3 o’clock is balanced by the running seconds sub-dial at 9 o’clock, while the day and month windows in the upper section of the dial are balanced by the circular moon-phase and date indicator at 6 o’clock. The finely textured ‘azurage’ finish on these three sub-dials, and the rich blue of the moon-phase indicator, create a subtle and pleasing contrast to the vibrant black of the sunray-brushed dial, which captures and reflects the light with movements of the wearer’s wrist. Legibility is further enhanced by the contrast between the warm pink gold tone of the Dauphine hands and applied trapezoidal indexes.

Elegant Proportions for the Modern Sophisticate

With its 40-millimetre diameter, outwardly sloping bezel and dynamically curved lugs, the pink gold Master Control case exudes a relaxed and understated elegance. Satin-brushing on the case-sides and lugs is complemented by the polished bezel, crowns and lug bevels. Refined details abound, including bas-relief engravings on the back bezel and a sapphire crystal case-back to reveal the finely finished and decorated movements. Enhancing this timeless style, rectangular chronograph pushers add a purposeful, modern air to the well-proportioned 12.05mm thick case. A black alligator leather strap adds allure to the pink gold case, honouring a classically elegant aesthetic that has been appreciated for many generations.

Technical Complexity Expressed Through Mechanical Elegance

A fine example of Jaeger-LeCoultre’s technically sophisticated and mechanically elegant watchmaking, the Master Control Chronograph Calendar is powered by the automatic Calibre 759. An integrated chronograph movement with a 65-hour power reserve, it features a column-wheel chronograph mechanism with vertical clutch, allied to a triple calendar with moon-phase display.

The fine finishing, visible through the sapphire crystal case-back, includes Côtes de Genève, blued screws, and Jaeger-LeCoultre’s emblematic open-worked gold rotor bearing the ‘JL’ motif. Like all of the Maison’s calibres, the movement was entirely designed, produced, finished and assembled within its own Manufacture at Le Sentier, in Switzerland’s Vallée de Joux.

2022 marks the 30 years of the Master Control, launched in 1992 as a demonstration of the Maison’s commitment to the very highest levels of watchmaking excellence. The Master Control marked the beginning of the 1000 Hours Control system of internal quality standards at Jaeger-LeCoultre, a system subsequently incorporated throughout the full range of watches and which is now emblematic of the Maison’s fine watchmaking promise to its customers.

The Master Control epitomises the dedicated approach to precision timekeeping at Jaeger-LeCoultre. In addition, the collection is a celebration of the continued value of mechanical watchmaking and its most emblematic complications, even in the 21st century. Two new Master Control models, in stainless steel with interchangeable bracelets, bring the calendar display and chronograph function more fully into contemporary everyday life, recognising the prominence of active lifestyles in the world today.

Earlier this year at Watches and Wonders 2022, the Maison demonstrated its exceptional savoir-faire in the domain of calendar watches. Timepieces such as the Master Hybris Artistica Calibre 945 and the Atmos Hybris Mechanica Calibre 590 represented some of the most sophisticated mechanical expressions of cosmic time in modern horology.

Expanding the utilitarian side of calendrical watchmaking at Jaeger-LeCoultre are two new interpretations of the Master Control Calendar and the Master Control Chronograph Calendar.

Building on the recent success of the Master Control Calendar with blue dial, the latest Master Control Calendar with interchangeable bracelet comes in a dial colour palette that focuses on purity and refinement. The silver sunray-brushed dial features a tone-on-tone aesthetic, maintaining the essential design codes of the Master Control such as dauphine hands and Arabic numerals intercut with dart hour markers. The jumping date hand that characterises this model is endowed with a red-lacquered indicator tip in the shape of the Jaeger-LeCoultre logo, allowing the date to be read easily and intuitively.

The Master Control Chronograph Calendar is equally pure in its chronometric expression, using blue chronograph hands and a blue moonphase disc to bring out the indications of the complications. For the first time, both the Master Control Calendar and the Master Control Chronograph Calendar are available on a steel bracelet with a quick-change system — a timely reflection of the ever-growing importance of versatile and robust-wearing timepieces in contemporary life.

Both the new Master Control models with steel bracelet also come with a light-brown strap in Novonappa® calf leather. These leather straps are equipped with the same quick-change system, allowing the Jaeger-LeCoultre Master Control to truly become a watch for all seasons.

2022 marks the 30 years of the Master Control, launched in 1992 as a demonstration of the Maison’s commitment to the very highest levels of watchmaking excellence. The Master Control marked the beginning of the 1000 Hours Control certification of internal quality standards at Jaeger-LeCoultre, a system subsequently incorporated throughout the full range of watches and which is now emblematic of the Maison’s fine watchmaking promise to its customers.

In full alignment with this unceasing commitment to timeless quality that maintains Jaeger-LeCoultre at the forefront of 21st-century horological craft, the Master Control collection has been enriched with two stainless steel models with sunray-finished dials in a refined shade of blue. All the essential codes of the Master Collection can be found in the Master Control Date and the Master Control Calendar. These include features such as the combination of applied Arabic numerals with faceted dart markers for the hours, faceted dauphine hour and minute hands, and bevelled case lugs that curve towards the strap attachment point. The slim case bezels bring an open feel to the 40mm cases, symbolic of the inherent versatility in this case diameter.

Legibility and readability are emphasised, using minute scales in a subtly contrasting lighter blue, with distinct minute divisions intercut with dot markers in Super-LumiNova® for an intuitive and precise indication of the time. With the Master Control Calendar, the jumping date indication makes a welcome reappearance. A slender date hand extends outwards from the centre of the dial, ending in a red-lacquered Jaeger-LeCoultre logograph that points towards the date on the outer periphery of the dial. For optimal reading of the dual-display moon phase and small seconds subdial, the date hand makes a 90° jump between the 15th and 16th day of each month. This ensures that the moon phase and small seconds subdial is never bisected by the date hand; a small yet effective detail that increases the design clarity of the Master Control Calendar.

To complete the overall harmonious aspect of these two new models, the date ring of the Master Control Date is also in blue, with white transferred Arabic numerals. The white-on-blue day and month indications of the Master Control Calendar provide similar aesthetic integration with the rest of the watch, with additional visual refinement found in the snailed finish of the small seconds subdial. The upper half of the subdial reveals the moonphase disc decorated with a star-studded background.

Both the Master Control Date and the Master Control Calendar come with matching blue straps in calf leather. The straps are trimmed in complementary blue stitching that continues across the strap attachment point for a touch of vintage allure. These straps have been fitted with a quick-change mechanism, allowing the wearer to easily switch between a range of straps for a completely different look.

Within these new models beats two Jaeger-LeCoultre in-house automatic movements. The Calibre 899 of the Master Control Date and the Calibre 866 of the Master Control Calendar have 70 hours of power reserve, bringing close to three days of running autonomy even when they are not being worn. Each model is limited to 800 pieces.

·        The Memovox Timer offers an additional alarm-setting function based on elapsed time

·        The Jaeger-LeCoultre Calibre 956AA was entirely redesigned for the new generation of Memovox timepieces

Since Jaeger-LeCoultre launched the first Memovox watch in 1950, it has become the reference in wristwatch alarms, with various useful and innovative functions added to create different Memovox models over the decades.

In 2020, the Manufacture’s engineers developed an entirely new alarm-setting mechanism – the Memovox Timer. With the initial steel-cased model now highly sought-after by collectors, Jaeger-LeCoultre introduces a new aesthetic interpretation: the Master Control Memovox Timer in pink gold.

The Timer function enables the watch owner to set the alarm based on the number of hours that should elapse before the alarm rings. Alternatively, the owner may set the alarm in the traditional way, based on a particular time (such as the time of an appointment or a wake-up alarm). The indicators are linked, so that whichever alarm-setting method is chosen, the second indicator will automatically move to the corresponding position.

The dial of the Master Control Memovox Timer is laid out in concentric circles – the black sunray-brushed background provides a rich contrast with the grey of the outer minutes ring and the alarm-indication disc. The innermost ring is engraved in bas-relief with highly polished numerals standing out against the granular texture of the background. Here, the elapsed hours-until-alarm are indicated by a small hand tipped with a red JL logo. Set at the outer edge of the ring, the Memovox’s signature triangular marker points to the time at which the alarm will ring, indicated on a second concentric ring. Adding refinement, the elongated triangular shape of the applied hour indexes – a signature of mid-century Memovox models – is echoed by the elegant simplicity of the Dauphine hands.

Contrasting with the deep shades of the dial, the pink gold 40-millimetre Master Control case exudes a relaxed and timeless elegance, with its sloping bezel, dynamically curved lugs and mix of polished and satin-brushed surfaces.

The Origin of the Memovox Legend

Despite being one of the most useful – and charming – of all complications, the alarm remains surprisingly rare in horology. The Memovox story began in 1950, a time when the world experienced a great burst of energy and inventiveness. Against this backdrop, Jaeger-LeCoultre harnessed its mastery of chiming mechanisms to develop an alarm watch – a highly practical timepiece that seemed perfectly suited to the times.

In common with other chiming watches, an alarm mechanism has a hammer and gong; however, its particular technical challenge is that the hammers must strike the gong multiple times at very high speed, for a relatively extended period.  

A Redesigned Movement

For the latest generation of alarm watches, the Manufacture’s engineers comprehensively revised the self-winding Calibre 956, which – like all Jaeger-LeCoultre calibres – had been entirely conceived, developed and produced in-house. Previously, Memovox watches had a closed case-back, to which the gongs were attached; however, the new Master Control case has a transparent sapphire back, allowing the wearer to enjoy watching the hammers in action. This demanded a complete redesign of the striking mechanism, with the gong now attached to the case side. An open-worked pink gold rotor, decorated with Côtes de Genève to match the fine finishing on the movement plates, ensures an unobstructed view of the strike-works. One important element remains unchanged from previous generations, however: the signature “school bell” sound of the alarm, which lends such charm to the Memovox.

The Master Control Memovox Timer in pink gold will be produced in a limited edition of 100 pieces, available exclusively from Jaeger-LeCoultre boutiques.

Despite being one of the most useful (and charming) of all complications, the alarm remains surprisingly rare in horology. In the 70 years since Jaeger-LeCoultre launched the first Memovox, it has become the reference in wristwatch alarms, appearing in timepieces designed for both urban lifestyles and underwater sports.

The Memovox story dates back to the late 1940s. As the post-war economy recovered, the world experienced a great burst of energy and inventiveness: technology gave rise to entire new industries, cities expanded, and the businessman-on-the-move personified the mood of optimism and confidence.

Against this backdrop, Jaeger-LeCoultre harnessed its mastery of chiming mechanisms to develop an alarm watch – an immensely practical timepiece that seemed perfectly suited to the times. While an alarm mechanism draws its inspiration from minute repeaters, its particular challenge is that the hammer must strike the gong multiple times at very high speed.

A new generation with a transparent sapphire case-back

This year, to launch the new-generation Master Control Memovox, Jaeger-leCoultre has taken inspiration from the first Memovox watches of the 1950s, giving it a contemporary style, while retaining the spirit of utility and charm that defined the originals. Continuing the tradition of adding useful auxiliary functions, the new Master Control Memovox Timer incorporates an entirely new alarm-setting mechanism, while the Master Control Memovox, brings clean-lined contemporary style to the classic alarm-plus-date model.

For this new generation of alarm watches, the Manufacture’s engineers have comprehensively revised the self-winding calibre 956. Previously, Memovox watches had a closed case-back, to which the gong was attached; however, the new Master Control case has a transparent sapphire back, allowing the wearer to enjoy watching the hammer in action. This demanded a complete redesign of the striking mechanism, with the gong now attached to the case side. A new, open-worked pink gold rotor, decorated with Côtes de Genève to match the fine finishing on the movement plates, ensures an unobstructed view of the strike-works. One important element remains unchanged, however: the signature “school bell” sound of the alarm, which lends such charm to the Memovox.

MASTER CONTROL MEMOVOX

Reinterpreting the graceful and uncluttered dial of the original 1950 Memovox in a streamlined modern style, the new Master Control Memovox presents the classical combination of alarm and date display with a silvery sunray-brushed dial. The applied indexes add refinement, their elongated triangular shape – a signature of mid-century Memovox models – is echoed by the Dauphine hands, and a blue seconds hand adds a subtle pop of colour to animate the silvery-white palette.

MASTER CONTROL MEMOVOX TIMER

Over the decades, underlining the practical value of alarm watches, Jaeger-LeCoultre has added various useful functions to its Memovox models, such as a world time-zone indicator and a parking-meter reminder. In the same spirit, its engineers have now developed an entirely new useful function: the Timer.

This enables the owner to set the alarm based on the number of hours that should elapse before the alarm rings (for example, the duration of a meeting or the number of hours of sleep on a given night). Alternatively, the owner may set the alarm in the traditional way, based on a particular time (such as the time of an appointment or a wake-up alarm to catch a flight). The indicators are linked, so that whichever alarm-setting method is chosen, the second indicator will automatically move to the corresponding position.

The dial is laid out in concentric rings, in two shades of blue with a sunray finish, complemented by an inner ring engraved in bas-relief with polished numerals. On this inner ring, the elapsed hours-until-alarm are indicated by a small hand tipped with a red JL logo. Set at the outer edge of that ring, the Memovox’s signature triangular marker points to the time at which the alarm will ring.

The Master Control Memovox Timer will be produced in a limited edition of 250 pieces.

Both Memovox models are presented in the new 40-millimetre Master Control case. With its sloping bezel, dynamically curved lugs and mix of polished and satin-brushed surfaces, the design exudes a relaxed, contemporary elegance.

In 2020, La Grande Maison relaunches the collection, drawing inspiration from the classic round watches of the 1950s, such as the Futurematic, PowerMatic and Memovox models, and adding a dash of 21st-century flair.

Rather than paying homage to a single historic reference, Jaeger-LeCoultre presents a range of timepieces featuring some of its most emblematic complications.

Designed for the urban sophisticate, every element of the Master Control line has been restyled. Jaeger-LeCoultre’s designers have harnessed and modernised the Maison’s classical design codes to create a refined yet entirely contemporary aesthetic that highlights the collection’s complications. A new case design heralds the introduction of a new pink gold alloy – Le Grand Rose gold®.

When launched in 1992, the Master Control line was the first of Jaeger-LeCoultre’s collections to benefit from its pioneering ‘1000 Hours Control’ certification – which inspired the collection’s name. A demanding process that tests the entire cased-up watch (not just its movement), it set a new benchmark when introduced and has continually evolved in response to technological advances, to remain one of the watch industry’s most stringent testing protocols.

Naturally, with this background and the Maison’s long history of technical innovation, the relaunch of Master Control is not simply a stylistic exercise. The Manufacture’s engineers have comprehensively revised and updated all of the movements, increasing power reserves to as much as 70 hours and enhancing overall performance and reliability. Like all Jaeger-LeCoultre timepieces, the Master Control watches carry an 8-year warranty in addition to the 1,000 Hours Control certification.

TIMELESS DESIGN CODES WITH A CONTEMPORARY TWIST

With its 40-millimetre diameter, outwardly sloping bezel and dynamically curved lugs, the new Master Control case exudes a relaxed and understated elegance – timeless yet absolutely contemporary. Satin-brushing on the case-sides is complemented by the polished bezel, crowns and lugs. Refined details abound, including bas-relief engravings on the back bezel and a sapphire crystal case-back to reveal the finely finished and decorated movements.

On the dials, Jaeger-LeCoultre’s designers have reinterpreted the Maison’s classical codes in a streamlined and modern style, in order to highlight each model’s complications. The applied indexes add refinement, their elongated triangular shape echoed by the Dauphine hands. Uniting the collection, sunray brushing animates the silvery-white background colour, a blue central seconds hand adds a subtle pop of colour and, according to the model, blue subdial hands further accentuate the complications.

LE GRAND ROSE GOLD®  – A NEW PINK GOLD ALLOY

The versatility of the new collection is underlined by the choice of two case materials – steel and Le Grand Rose gold®. Seen for the first time in the new Master Control line, the new pink gold alloy has a remarkable sheen and depth of colour. The addition of palladium to the metal’s proprietary formula (the exact details of which remain a closely guarded secret) guards against oxidation and ensures that the radiant colour will not fade over the years.

NEW CALFSKIN LEATHER WATCH STRAPS NOVONAPPA®

The straps, too, have been re-worked for the new collection. To complement the timeless informality of the steel cases, Jaeger-LeCoultre’s designers have chosen the soft, matt finish of Novonappa® calf leather in tan. Produced by the finest tannery in France, through a vegetable-based tanning process that retains the natural variations of the hides, Novonappa gains a distinctive patina over time. Thanks to a Presto Spring lug attachment and a simple clip for removing and refitting the deployant buckle, the Novonappa straps can be quickly changed, without the need for any tool. Classical alligator leather in black or chocolate brown lends a more formal allure to the Le Grand Rose gold® cases – which can also be fitted with Novonappa straps if preferred.

UPGRADED CALIBRES AND NEW COMPLICATIONS

With the goal of improving reliability, power reserve and long-term performance, Jaeger-LeCoultre’s engineers have comprehensively revised and re-engineered Calibre 899, the high-performing pillar of the Master Control collection. The improvements, which have been incorporated into the entire range of Master Control calibres, include a silicon escapement, a redesigned barrel and various energy-saving enhancements.

MASTER CONTROL CHRONOGRAPH CALENDAR

The headline model of the new Master Control collection features a newly developed movement, Calibre 759, which combines a chronograph with a triple calendar display and a moon-phase. Brought together for the first time in a Jaeger-LeCoultre timepiece, this alliance of complications evokes the ancient links between watchmaking and astronomy. The new Calibre 759 features a column-wheel chronograph with a vertical clutch, a moon-phase indicator, and a 65-hour power reserve.

With a balanced dial layout that combines the familiarity of two classical complications – a triple calendar and a bi-compax chronograph – Jaeger-LeCoultre’s designers have made the reading of the displays straightforward and intuitive, despite the complexity of the information shown. The 30-minute chronograph counter at 3 o’clock is balanced by the running seconds subdial at 9 o’clock, while the day and month windows in the top part of dial are balanced by the moon-phase and date indicator at 6 o’clock. The entire display is anchored by the central chronograph seconds hand and contained by the pulsometric scale marked around the dial flange. Complementing the Chronograph Calendar’s timeless style, rectangular chronograph pushers add a purposeful, modern air to the well-proportioned 12.05mm thick case, which is offered in steel or Le Grand Rose gold®.

MASTER CONTROL DATE
 

With its cool, silvery-white colour palette, minimalistic design and refined details, the Master Control Date anchors the new collection. Thanks to its slim movement, Calibre 899, the 40mm steel case of the Master Control Date is just 8.78mm thick. A Jaeger-LeCoultre mainstay since its introduction fifteen years ago, Calibre 899 has been repeatedly updated to incorporate the latest performance-enhancing technology.

Revised again for the new Master Control collection, the latest-generation Calibre 899 features a new escapement and pallets: reconstructed in a slightly modified shape, they are made of silicon to minimise friction and thus consume less energy. The central-seconds wheel has been redesigned to eliminate shaking; the fixing screws of the oscillating wheel are made of highly resistant titanium, rather than steel; and new oils, specifically formulated for the new materials, have been used. In order to increase the power reserve to 70 hours, the barrel was redesigned to accommodate a stronger and longer mainspring without increasing the 3.3mm height of the movement.

MASTER CONTROL CALENDAR

In the 1940s and ’50s Jaeger-LeCoultre was renowned for its triple calendar moon-phase movements, and the new Master Control Calendar brings that tradition into the 21st century. With a case measuring 40mm x 10.95mm, it is offered in either steel or Le Grand Rose gold®.

The finely balanced classical layout of the dial is retained, with the dates marked around the periphery, indicated by a red-tipped hand, the days and months displayed in the upper part of the dial, and the moon-phase set within the small seconds subdial in the lower part. But there is a fresh new twist to the date display: as well as updating Calibre 866 with the same performance-enhancing improvements made to cal.899, Jaeger-LeCoultre’s engineers have added a delightful new jumping complication. Every month, the date hand makes a 90-degree leap from the 15th to the 16th, in order not to obscure the moon-phase display.

MASTER CONTROL GEOGRAPHIC
 

Jaeger-LeCoultre’s unique interpretation of the travel watch has been a feature of the Master Control collection since 1990, much appreciated by connoisseurs. Rather than indicating only the hour of a second time zone, the Geographic also has a 24-hour night/day indicator and, in an aperture at the bottom of the dial, displays the city name relating to the zone. This gives travellers the option of setting the second time by location, rather than needing to calculate the time difference. The dial adheres to the familiar Geographic layout, with time-zone displays balanced by a date subdial and a power reserve indicator, and blue steel hands adding a pop of colour to enhance legibility. But now, the entire dial is sunray-brushed, contained within a wide, convex flange on which the elongated triangular indexes are set. The profile of each index has been shaped to fit perfectly flush with the curve where the flange meets the dial – a challenge to Jaeger-LeCoultre’s artisans but entirely in keeping with the Maison’s attention to detail.

The new-generation Calibre 939 increases the power reserve of the Master Control Geographic to 70 hours, while the case is available in a choice of steel or Le Grand Rose gold®.

Inspired by the past and redesigned in the confident spirit of the 21st century, the new Master Control collection combines the creativity and deep know-how of the Jaeger-LeCoultre Manufacture, where all mechanical movements are made in-house. Blending timeless style with the relaxed elegance of modern urban living, it is destined to become a point of reference in contemporary watchmaking.
