Reference 6263, together with its sister reference with metal bezel 6265, is the final evolution of the manually wound Daytona Cosmograph. It differentiates itself from previous iterations mainly by using the calibre 727, instead of calibres 72B, 722 and 722-1 which were found in earlier references. In production from the late 1960s to around 1987, it coexisted for a few years with reference 6264 (and 6262, with metal bezel), however it was soon discontinued, and its pump pushers were replaced in later iterations with screw down pushers.
Considered one of the most appealing versions of vintage Daytona, the present watch is furthermore graced by the rare and extremely elegant "Panda" Paul Newman dial, distinguished by black subsidiary dials on a white background, and an absolute lack of any other colors: there is no red Daytona designation, and the fifth of a second divisions are white instead of red. The “ROC” printing was only produced in the very early batch of 6263. The word “Oyster” is added between “Rolex” and “Cosmograph” indicating the upgraded water proof ability by introducing screw pushers. The "Panda" Paul Newman reference 6263 is one of the most desirable watches for Rolex collectors.
