In the early 70’s – at the end of the production period of the 6262/4 – Rolex introduced their new models, the 6263 (and 6265) which featured an evolution of the screw-down pushers introduced on the 6240.
The main goal was of course to obtain a better waterproofness but some esthetics’ details were also modified which globally changed the design of the watch – the “impression” made by a 6263/6265 is more muscular, more present than the one given by a push-down model, although the case diameter are identical.
The watch seems to be bigger and more modern. This last generation of screw-down Daytona were the longest produced and the most popular, with continued success until the late 80’s.
