4130, Manufacture Rolex
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.

Superlative Chronometer (COSC + Rolex certification after casing)
The green seal accompanying every Rolex watch is a symbol of its status as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of specific final controls by Rolex in its own laboratories according to its own criteria, in addition to the official COSC certification of its movement. This unique testing of the chronometric precision of the cased-up movement, as well as of the watch’s waterproofness, self-winding and power reserve, pushes back the boundaries of performance and makes Rolex the benchmark for excellence in mechanical watches. The green seal is coupled with a five-year guarantee which applies to all Rolex models.
