deLaCour BiTourbillon

The BiTourbillon by deLaCour is by its nature unique. These exclusive timepieces will never be assigned numbers or serial numbers, each will individually named. Their names representing the personality and unique identity of each piece. Flying bi-tourbillon driven by a differential to maintain a constant force.

The differential allows the equalization of the function of the two tourbillons and improves the precision. Indication of the hour and second time zone with instantaneous change. Indication of the moon phase with a mechanism that shows a shooting star passing furtively every 6 minutes in front of the moon phase. Power reserve 50 hours.
