DeLaCour Calibre bi-tourbillon

SWISSTIME CONTENT

For this splendid “Grande Complication” watch, each of which is unique, Pierre Koukjian has called upon the talents of 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 moon phase.
