The headline model of the new Master Control collection features a newly developed movement, Caliber 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 Caliber 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.
