The Oyster Perpetual Cosmograph Daytona in Oystersteel with a black dial and contrasting counter rings. It features an Oyster bracelet and a black Cerachrom bezel with tachymetric scale.

A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. Blending high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert.
