Vulcain V-21

The V-21 is an automatic movement from Vulcain, evolved from the manual-winding V-10. It measures 12 lignes (28mm) and contains 28 jewels across 263 components—100 more than its predecessor—operating at 18,000 vph with a 42-hour power reserve. The movement features twin-barrel architecture, unidirectional rotor with ball bearings, and the Exactomatic system for balance precision. Its alarm sounds for approximately 20 seconds. The V-21 powers the 50s Presidents' Watch and Cricket X-Treme, and remains in production.
