Jaeger-LeCoultre and New Models for its Master Control Collection
Since it was introduced in 1992, Jaeger-LeCoultre’s Master Control collection has been defined by technical rigour and stylistic restraint, its constant evolution imbued with the Maison’s deep respect for tradition and constant quest for innovation.
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 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 heat-blued 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®.
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.
