Twin-Beat - 2019
When worn, the Traditionnelle Twin Beat perpetual calendar movement beats at a high frequency that is aligned with modern active lifestyles, displaying the hours, minutes, date, month, leap year cycle and power reserve on its dial. A feat of technical prowess, this unique piece utilizes a patent-pending mechanical system that allows instantaneous switching between high-frequency Active mode (5Hz, 36,000 vph), and low-frequency Standby mode (1.2Hz, 8,640 vph). Both the Active and Standby balances are driven by the same mainspring barrel, which is the most efficient way of distributing energy and the only way to have a single power-reserve indication. When the watch is not being worn, it allows for an extended power reserve of at least 65 days.
