Launched in 1963, the Cosmograph Daytona has long since transcended its status in the world of watchmaking to become an icon. Its name, inextricably linked to the famous racetrack, as well as its graphic face, have made it a legend. Yet it is at the heart of this exceptional chronograph that the true mechanics of the legend beat: a movement designed and produced entirely by the Rolex manufacture that delivers superlative performance in all circumstances. Constantly improved and refined over time, the Cosmograph Daytona has proved to be as reliable as it is precise.
On the one hand, its simplified architecture creates space for the barrel, providing a power reserve of approximately 72 hours. On the other hand, its vertical clutch mechanism guarantees prolonged operation of the chronograph without compromising chronometric precision. This is complemented by the outstanding performance of the Chronergy escapement and the Parachrom hairspring. The hermetic qualities of the Oyster case are maintained by the screw-down pushers and the Triplock winding crown, equipped with a triple waterproofness system.
The Cosmograph Daytona is emblematic of Rolex’s expertise and stands out by virtue of its chronometric precision as well as its unfailing reliability. For years, Rolex engineers worked on the design and development of calibre 4130, which was optimized to become calibre 4131 in 2023. An adaptation of calibre 4131, calibre 4132, was also launched the same year. Since its creation, the calibre, which is comprised of a minimal number of parts, has established itself as one of the most efficient and robust in the world.
