The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex, offering a power reserve of approximately 72 hours. This movement incorporates a chronograph function with a reduced number of components, thereby further enhancing its reliability. The chronograph is engaged by a mechanism with a column wheel and vertical clutch. This enables an instantaneous and extremely precise start to the timing.

Like all Rolex watches, the Cosmograph Daytona is covered by the Superlative Chronometer certification. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories, according to its own criteria. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.

The Daytona International Speedway® opened in 1959, and Rolex has been the Official Timepiece of the circuit ever since. A few years later, to emphasize the brand’s connection to the American racetrack, Rolex gave its new model the name Cosmograph Daytona.

Over the decades, the brand’s presence in high-octane racing has grown steadily, its support extending to the leading drivers and events worldwide. For much of this historic journey, the Cosmograph Daytona has embodied the privileged bonds between Rolex and motor sport.
