Miniature Mechanical Art Treasures

The Jaeger-LeCoultre Duomètre watch series is unique in style and technology. It is the pinnacle of horological art. Its latest-generation movement combines the novel Dual-Wing design concept. The bi-wing movement has two sets of independent mechanical devices, but they share the same adjustment mechanism, bringing real changes to precise timing. Each device has its own power source and gear train. Today’s Watch House brings you a short review of a Jaeger-LeCoultre biplane watch, the official model of the watch is: Q6012420.

Precision machinery and elegant temperament embody the essence of all works since 1833. The past, present and future are perfectly blended in this work. This model’s Dual-Wing system is divided into two groups of mechanical devices: one group displays the local time, and the other is a timing device. The two sets of mechanical devices share the same adjustment mechanism, and each has its own independent power source, thereby avoiding the energy loss caused by the interaction between the devices. The operation of the timing device will not affect the overall operation of the watch, thereby greatly improving the accuracy of timing.
