Notes

Rolex, Reference 6239 In 1963, the first “Cosmograph” introduced into Rolex’s collection was launched. In 1964, Rolex joined the French races “Le Mans” and also with the famous American car circuit “Daytona”. The “Cosmograph” was first marketed under the name “Le Mans”, but Rolex very quickly opted for the name “Daytona”. This is the beginning of a legendary adventure!
