The Rolex Cosmograph Daytona, introduced in 1963, was designed to meet the demands of professional racing drivers. With its highly reliable chronograph and bezel with tachymetric scale, it allows drivers to perfectly measure average speeds up to 400 kilometres or miles per hour, as they choose. An icon eternally joined in name and function to the high‑performance world of motor sport.
Rare and precious, platinum is striking for its silvery whiteness and vibrant luminosity. It is among the densest and heaviest metals in the world, distinguished by unique chemical and physical properties such as exceptional corrosion resistance. Paradoxically, it is also soft, elastic and highly malleable, which makes machining and polishing especially difficult, demanding an extremely high degree of skill. Rolex always uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum, painstakingly crafted in-house by the fine metalworkers at Rolex. The noblest of metals for the finest of watches.
The central sweep seconds hand allows an accurate reading of 1/8 second, while the two counters on the dial display the lapsed time in hours and minutes. Drivers can accurately map out their track times and tactics without fail.
The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The Oyster bracelet is a perfect alchemy of form and function. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex. Its architecture incorporates far fewer components than a standard chronograph, thereby enhancing the movement’s reliability. Like all Rolex Perpetual movements, the 4130 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The chronograph movement features a Parachrom hairspring, offering greater resistance to shocks and to temperature variations.
