Cosmograph Daytona White Gold Bright Black & Steel Diamond

The Cosmograph Daytona was designed to be the ultimate timing tool for racing drivers thanks to its precision and its reliability. The watch, which is equipped with an additional mechanism to measure intervals of time displayed by secondary hands, also offers outstanding legibility of its functions. Time intervals can be measured to within one-eighth of a second with the centre chronograph seconds hand, while the two counters on the dial at 3 and 9 o’clock display elapsed time in minutes and hours respectively.

The Cosmograph Daytona’s bezel, in gold or high-tech ceramic, functions as a tachymeter: its scale can be used to read an average speed over a given distance based on elapsed time. This scale, which offers optimal legibility, makes this watch the ideal instrument for measuring speeds up to 400 units per hour, expressed in kilometres, miles, or any other unit of measure. The Cosmograph Daytona’s Oyster case, 40 mm in diameter and guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The Cosmograph Daytona is equipped with calibre 4131, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex.
