The Rolex Cosmograph Daytona is a mechanical chronograph wristwatch designed to meet the needs of racing drivers by measuring elapsed time and calculating average speed. Its name refers to Daytona, Florida, where racing flourished 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.
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.
