The Oyster Perpetual Cosmograph Daytona in platinum features an ice-blue dial and contrasting counter rings. It features an Oyster bracelet and a chestnut brown 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. The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays.
