The Rolex Cosmograph Daytona is a mechanical chronograph wristwatch designed to meet the needs of racing drivers by measuring elapsed time and calculating average speed. Its name refers to Daytona, Florida, where racing flourished in the early 20th century. It has been manufactured by Rolex since 1963 in three distinct generations (or series); the second series was introduced in 1988, and the third in 2000. While cosmetically similar, the second series introduced a self-winding movement (the first series is hand-wound), and the third series brought the manufacture of the movement in-house to Rolex.
The classic Rolex Daytona has a 40mm stainless steel case and a white dial with steel and luminous hands and index hour markers. There are also 3 chronograph subdials. The watch is on a stainless steel oyster link bracelet with a folding deployment clasp fastening.
