SIHH 2019: Vacheron Constantin absolutely knock it out of the park with this world first complication. The Twin Beat Perpetual features a user selected frequency pusher which allows the wearer to change the frequency from 5hz when wearing the watch (giving a 4 day power reserve) to a 1.2hz ‘rest mode’ giving a crazy 65 day+ power reserve. The perpetual calendar is instantaneous in both modes. Case size is 42mm. Arguably the watch of the show 👏🏽 vacheronconstantin #vcsihh #vacheronconstantin #twinbeatpeepetual #sihh2019
