Cosmograph Daytona ambiance

An exceptional chronograph

• 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.
