deLacour Calibre bi-tourbillon

Introduced by deLacour in 2005, this Grande Complication watch, each of which is unique, was developed in association with world renowned watchmaker Christophe Claret. This mechanism represents a genuine technical feat and incorporates two world premières. In addition to its flying bi-tourbillon mechanisms, this watch features an original dual time-zone display, a moon-phase indication, as well as an exclusive module that sends a shooting star gliding swiftly over the moonphase.
