This Oyster Perpetual Cosmograph Daytonain
Oystersteel, with a white dial and an Oyster bracelet, features black Cerachrom bezel with an engraved tachymetric scale.

High-performance chronograph
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.
