The company Jaeger-LeCoultre in 2010 at the annual exhibition presents new versions of SIHH watch Duometre a Quantieme Lunaire.

This year, fans of watchmaking was a new model Duometre a Quantieme Lunaire (Ref. Q6042521), slightly modified in the direction of decreasing body size. Reducing the diameter of the body did not affect the harmonious proportions of the dial, the masters of the company managed to keep its balanced structure, “adapt” to new dimensions hours. Location indicator has not changed: the lateral face to the right shows hours and minutes, date indicator located on the left and the moon phase indicator.

Second shows the central arrow, and in the “6” hours is “jumping” second hand, makes a complete rotation every 6 seconds. Traditional indicators of the range symmetrically placed on the “5” and “7” hours.

Dial with multi-display system is covered with sapphire crystal and “fringed” body satin 18K gold.

Hours are collected on the basis of the manufacturing machinery with manual winding Calibre Dual-Wing Jaeger-LeCoultre 381. Caliber is divided into two parts (the Dual Factory Dual-Wing), each with a separate drum and a spring motor that provides 50-hour power reserve.

Despite this “autonomy” in their motion causes a crown: depending on the adjustment (clockwise or counterclockwise) of the plant or that the drum. The first mechanism supports hours, minutes, second’s hands, date index, indicator, moon phases and “jumping” second hand, and the second is used exclusively for the descent. They connect and coordinate the “jumping” second hand, which provides precision timing to 1 / 6 seconds.

Establishment of a mechanism with two independent power sources challenged the fundamental principles of the theory of time. Until recently it was thought that the exceptional accuracy can provide hours, not equipped with sophisticated complications. When supplying additional complications caliber usually there are some failures, as part of the energy from the drum moves in complication. Activation of each of them is due a certain amount of power the drum and leads to small deviations in the time dimension.

The revolutionary design watchmakers Jaeger-LeCoultre caliber is based on the creation of two independent watch movements: separating the energy mechanism of the energy of the complications could provide a constant power supply to the controller.

The mechanism is completely designed and assembled in the factory workshops. Reliable gauge diameter of 33.70 mm is 367 parts (40 stones, the frequency of oscillation of the balance of 21 600 pc / h, power reserve – 50 hours).
