The Oyster Perpetual Cosmograph Daytona is resolutely dedicated to those who enjoy the finer things in life. The typical owner of this Rolex chronograph, designed with
speed and performance in mind, is among those who avidly take advantage of all that life has to offer, love the freedom of the open road and are not afraid to take the turns tightly.
Speed and Motorsports
Launched in 1963, the Rolex Cosmograph Daytona is closely linked to speed and motorsports. Its automatic chronograph movement allows short periods of elapsed time to be measured to within 1⁄8th of a second, and the tachymetric scale on the bezel enables the instant reading of speed overa given distance. Adopted by race car drivers for its performance, reliability and exceptional readability, this prestigious chronograph carries in red letters on its dial the name “Daytona” – the most famous race track in the United States.
Legendary heritage and exclusive technology
With its exclusive monobloc black CERACHROM bezel developed by Rolex – made of an advanced ceramic virtually impervious to scratches, corrosion-resistant and
non-fading – this version of the Rolex Oyster Perpetual Cosmograph Daytona exhibits state-of-the-art technologyand pays homage to its legendary heritage. Its black bezel is reminiscent of that of the 1965 model. The graduations on the CERACHROM bezel, offering perfect readability, are obtained by the deposition of a fine layer of pink gold via a magnetron cathode sputtering PVD process.
This high-precision Rolex chronograph certified by the Swiss Official Chronometer Testing Institute (COSC) is driven by calibre 4130, introduced in 2000, a movement with a column wheel and vertical clutch entirely designed and manufactured by Rolex. Its revolutionary architecture, the fruit of years of research, has reduced its complexity
and increased its reliability. A profusion of Rolex innovations, calibre 4130 is equipped with a PARACHROM hairspring with a Breguet overcoil. The hairspring is manufactured from an alloy, developed and produced by Rolex, which makes it insensitive to magnetic fields and up to 10 times more resistant to shocks.
