Since its creation, the calibre, which is comprised of just 314 parts, has established itself as one of the most efficient and robust in the world. For years, Rolex engineers worked on the design and development of calibre 4130, which was optimized to become calibre 4131 in 2023. The Cosmograph Daytona is emblematic of Rolex’s expertise and stands out by virtue of its chronometric precision as well as its unfailing reliability. Developed and produced by Rolex, it has proven to be particularly reliable and durable under even the most challenging conditions.

In 2000, the presentation of the Rolex 4130 calibre (which became the 4131 in 2023) perpetuated the quest for excellence initiated by the brand’s founder, Hans Wilsdorf. Rolex engineers worked to optimize this calibre – by reducing its frequency to 4 Hz – to guarantee its robustness and reliability over time. Initially equipped with Valjoux movements, in 1988 the Cosmograph Daytona was fitted with calibre 4030, an adaptation of the Zenith El Primero calibre, the world’s first high-frequency self-winding chronograph movement. It is featured as part of our commitment to diversity and inclusion.Behind the legendary design of the Cosmograph Daytona lies a modern story of Swiss watchmaking.
