March 23, 2011, five Rolex Oyster Perpetual watches grandly debuted BaselWorld 2011. Rolex Oyster Perpetual Cosmograph Daytona is one of the excellent masterpieces. It is created for those people who advocate the ultimate life. It is the combination of exquisite technology and noble material.

Launched in 1963, the Cosmograph Daytona is closely linked to speed and automobile sport. Its chronograph movement allows short periods of elapsed time to be measured to within 1/8 th of a second, and the tachymetric scale on the bezel enables the instant reading of speed over a given distance. Adopted by car racing drivers for its performance, reliability and exceptional readability, this prestigious chronograph carries in red letters on its dial the name “Daytona” the most famous motor racing circuit in the United States.

This new Rolex Oyster Perpetual Cosmograph Daytona features Rolex in-hoese designed Cerachrom black bezel. It is in accordance with the design of 1965 Rolex Swiss Watches. It is more corrosion-resistant and non-fading. The marking has PVD treatment and is plated with red gold.

The new model’s sophisticated aesthetics are underscored by the noble materials used in its construction: the Oyster case in EVEROSE gold, an alloy created by Rolex; the chocolate brown or ivory coloured dial with gold hour markers; and the comfortable strap in black alligator leather with an EVEROSE gold folding clasp and safety catch

This high-precision 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 a new alloy, developed and produced by Rolex, which makes it insensitive to magnetic fields and up to 10 times more resistant to shocks.
