The racing driver's choice
Ideal for measuring elapsed time and calculating average speed, the Oyster Perpetual Cosmograph Daytona is equipped with a sweep second hand, minute and hour totalisators activated by push buttons, and a graduated bezel which acts as a tachometer. It is self-winding and waterproof to 100 metres/330 feet.
