Traditionnelle Twin Beat Perpetual Calendar

Vacheron Constantin 2019

ref. 3200T/000P-B578
Men's

Vacheron Constantin breaks new ground with this perpetual calendar; an ostensibly classic complication – except that the watch is equipped with two gear trains, each with its own balance. One vibrates at a high frequency of 5 Hz (36,000 vph) while the other maintains a frequency of 1.2 Hz (8,640 vph). By pressing the pusher at 8 o'Clock, the wearer of the watch can switch between frequencies by "freezing" one or other of the balances. Switching to the lower frequency when the watch isn't worn means significantly less energy consumption, thereby extending the power reserve from four to 65 days. This is a major advantage as the calendar indications, which are tricky to reset, will remain accurate for over two months.
