Marcello C Unitas 6497

The Unitas 6497 is a hand-winding movement originally designed for pocket watches. Marcello C sources this caliber from Unitas (ETA) for select models in its collection. As an established Swiss movement supplier, Unitas has maintained production of the 6497 for use in contemporary timepieces. The caliber remains in production and is used in Marcello C watches that require a manual-winding movement.
