Cosmograph Daytona... a legendary name among watch aficionados, is one that conjures up montages of speed, engines and sound, but is also a symbol of prestige and admiration. The origin of the myth is linked to a city in Florida, Daytona Beach, famous for its motorcycle and automobile races on the beach. In 1959, the Daytona 500 race was born and three years later, Rolex became the official timekeeper of the Daytona International Speedway - hence, the start of the story of the legendary "Cosmograph Daytona". The chronograph complication and the history of Rolex have always been inextricably linked. Rolex's first foray into measuring time began in the 1930s with the manufacture's very first Oyster chronograph model. In 1963, Rolex launched the Cosmograph Daytona, a sports chronograph that has never stopped evolving in respect to the spirit of the brand, and which has always strived to improve existing technology by pushing the boundaries of what is technically possible. The history and diversity of this chronograph is such that two (independent) volumes have been devoted to it. This first volume is dedicated to hand-wound Daytonas, manufactured between 1963 and 1988.
