Rolex Oyster Perpetual Cosmograph Daytona is a chronograph that features a central chronometer seconds hand, minute and hour totalizers activated by screw-down pushers, and a graduated bezel that serves as a tachometer. It is the ideal instrument for measuring elapsed time and calculating average speed.
The Oyster Perpetual Cosmograph Daytona has, since 2000, been equipped with a new chronograph movement entirely designed and manufactured by Rolex. This movement includes a Parachrom hairspring, very resistant to shocks and magnetic fields, and has a 72-hour power reserve. Self-winding, equipped with a Perpetual rotor and certified by the Swiss Official Chronometer Testing Institute (COSC), the Oyster Perpetual Cosmograph Daytona is guaranteed waterproof to a depth of 100 metres (330 feet). It features a sapphire crystal and a Triplock winding crown protected by shoulders.
It is equipped with an Oyster bracelet with an Oysterlock clasp and an Easylink comfort extension link. An extremely versatile watch, the Oyster Perpetual Cosmograph Daytona is available in many versions, which include a wide selection of gem-set bezels and dials.
