ETA SA 7275

The 7275 is an automatic movement manufactured by Ginault, based on the ETA 2824-2 architecture. It measures 26mm in diameter and 4.65mm thick, beats at 28,800 vph, and delivers a 38-hour power reserve with 25 jewels. The movement features a date complication, hand-winding, and sweep seconds. Its distinguishing characteristic is the proprietary GC31 copper alloy used for powertrain gears, which Ginault states offers near-steel strength and antimagnetic properties. The caliber launched in 2016 and remains in production.
