Inspired by racecar drivers and enthusiasts, the Rolex Cosmograph Daytona was first released in 1963. This watch is an instrument of precision while performing multiple functions and calculations to allow drivers to measure speeds up to 400 km per hour. With a tachometer or calibrated bezel, accurate time totalizers, a sweeping second hand and watch functionality, the Daytona is an icon of the motor racing community as well as the general public. Everest straps are compatible with the SS and Yellow Gold Daytona cases that have Rolex bracelets. At this time, the straps are not compatible with the White or Rose Gold versions.
