ETA SA C609

The Clerc C609 is an automatic movement manufactured by ETA SA, based on the ETA caliber 2892-A2. Measuring 30 mm in diameter, it operates at a frequency of 28,800 vph with a 48-hour power reserve and 25 jewels. The movement features sweep seconds, hand winding, bidirectional winding, and date display, protected by Incabloc shock resistance. It holds COSC chronometer certification, and Clerc markets it as an exclusive caliber despite its shared base. The C609 remains in production and powers the Hydroscaph H1 collection.
