The ultra-thin Ref 878 is the brand’s very first limited edition. Unique and immediately recognizable, it eloquently conveys the brand’s aesthetic values of perfect craftsmanship and pure styling.

At just 6.5 mm thick, the Ref 878 is driven by the ETA7001 movement also known as the “Peseux” caliber. This mechanical hand-winding movement, renowned for its extreme reliability, is endowed with a 42-hour power reserve. It features small seconds at 6 o’clock and its water resistance is tested to 5 bars.
