The Cosmograph Daytona can be considered, without a doubt, among the most successful and well known line of chronograph wristwatches ever devised by any manufacturer. Introduced in 1963 with manually wound reference 6239, it underwent various evolutions before being upgraded with an automatic movement around 1988 (reference 16520). Reference 116520 was launched in 2000, the first Daytona equipped with a fully in-house Rolex movement.
