Valjoux Valjoux 7750 Chronometer

The Valjoux 7750 Chronometer is an automatic chronograph movement manufactured by Valjoux. It is the COSC-certified version of the base Valjoux 7750, retaining the 30mm diameter, 25-jewel construction, 28,800 vph frequency, and 48-hour power reserve of its predecessor while adding chronometer-grade precision certification. The movement features a cam-actuated chronograph with 60-second, 30-minute, and 12-hour counters along with a day-date display. It remains in production and is used by numerous brands requiring a certified chronograph movement.
