ROLEX | REF 6263 DAYTONA, A STAINLESS STEEL CHRONOGRAPH WRISTWATCH, CIRCA 1971 | 勞力士 | 6263型號「DAYTONA」精鋼計時腕錶，年份約1971

Produced in the late 1960s until the late 1980s, references 6263 and 6265 replaced the reference 6240, and represent the last iteration of the manual wound ‘Daytona’ series. The models feature two screw-down pushers and Rolex's trademarked ‘Oyster’ case design. These features were designed to increase the water proof qualities of the watch and in reference to this feature, the dials carried the ‘Oyster’ designation below the Rolex signature.

The model was offered with cases constructed from either stainless steel, 14k and 18k gold, with dial configurations typically showing as black with white sub dials or silvered dials with black sub dials on the steel models. The manual wound movement was also upgraded from a Valjoux 722 to the Valjoux 727. The reference 6263 featured a bezel with black acrylic insert featuring a tachometer scale printed in white and the 6265 featured a steel bezel with black enamel calibrations.
