The cosmograph daytona was introduced in 1963, was designed to meet demands of professional race drivers. With its highly reliable chronograph and bezel tachymetric scale, it allows drivers to perfectly measure average speed up to 400Km per hour.
The Oyster Perpetual Cosmograph Daytona swiftly became an iconic watch. Its dial carries in red letters the name “Daytona” – the most famous motor racing circuit in the United States. Available in 904L steel, 18 ct gold and Rolesor versions with a variety of dials, robust Oyster bracelets as well as elegant leather straps both equipped with high security Oysterlock clasps, the Cosmograph Daytona is tailored for the track and the concert hall.
The cosmograph daytona has bezel functions as a tachymeter by measuring elapsed time over a given distance. Combine with a chronograph, its scale provides a perfect instrument for measuring speed of up to 400 units per hour, whether expressed in kilometres or miles.
The Daytona’s chronograph functions are activated by pushers that screw down like the winding crown when they are not in use, guaranteeing waterproofness to 100 metres. One press to start, stop or reset the chronograph produces a crisp, clear click that was perfected using the most advanced technology. Rolex watchmakers also perfected the mechanism to suit the ideal finger pressure on the pushers, and engineered it to provide an instantaneous and accurate start to the timing without sacrificing reliability.
