With its tachymetric scale, its three counters and its pushers, the Cosmograph Daytona was designed to be the ultimate timing tool for endurance racing drivers. This chronograph allows the driver to measure elapsed time, which is displayed in hours, minutes and seconds on the dial.Read more
The bezel features a tachymetric scale to read average speed over a given distance based on elapsed time. This scale offers optimal legibility, making the Cosmograph Daytona the ideal instrument for measuring speeds up to 400 units per hour, expressed in kilometres or miles.
The Daytona’s chronograph function is activated by pushers that screw down like the winding crown when they are not in use. One press to start, stop or reset the chronograph produces a crisp, clear click.Read more
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement developed and manufactured by Rolex. Its architecture incorporates fewer components than a standard chronograph, thereby enhancing the movement’s reliability. It also saves space, making it possible to house a large mainspring and delivers a power reserve of 72 hours.
Calibre 4130’s performance stems particularly from the use of a vertical – instead of lateral – clutch to activate the chronograph.
This mechanical system functions on the principle of two discs, one above the other, which work together by direct friction contact and offer significant advantages: the precision of the start and stop functions as well as the smooth running of the chronograph seconds hand as soon as the pusher is pressed; and the capacity of the chronograph to function for long periods of time with no negative impact on the precision of the watch.
The monobloc Cerachrom bezel in high-tech ceramic on particular versions of the Daytona offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays.Read more
The Cosmograph Daytona is inextricably linked to the world of motor racing. It allows drivers to measure elapsed time and read average speeds on its trademark tachymetric bezel. The watch pays tribute to a place – Daytona, Florida – where passion for speed and racing developed in the early 20th century. The name embodies the historic and privileged bonds between Rolex and motor sport, which were strengthened in 2013 by the brand’s entry into the world of Formula 1® racing as Global Partner and Official Timepiece.
