At the beginning of the 1970s, Rolex presented two new chronograph references 6263 and 6265, replacing the first Oyster Cosmograph ref. 6240. In production for 17 years until the end of 1987, the Cosmograph Daytona adopted the use of screw-down pushers to improve the waterproofing mechanism range from 50 to 100 meters. Available in stainless steel and gold with two-toned dial combination, the references were fitted with a bezel with black insert for the 6263, and a metal only bezel on the 6265 like the present lot.
