The evolution of the Cosmograph Daytona is legendary. Over its 60-plus year life span, it has become an icon amongst chronographs for its strong masculine case, and classic sporty style. The references 6263 and 6265 were introduced into the market in approximately 1969, as an upgrade to the 6240, the first Daytona to feature screw down pushers. It is believed only 100 examples of both references in yellow gold were made each year, thus over its nearly 20 year run, only a very limited number were produced.
From the early 1980s and onwards, gold Cosmograph Daytonas featured a movement number engraved on the plate, behind the balance wheel. Research suggests that this was related to the officially certified chronometer certification. Around this period, Rolex modified the dial layout for gold versions, and the "Officially Certified Chronometer" designation was printed on the dial, which we see on the present example.
There is something about sports watches dressed in gold livery.
The present watch is rendered extraordinary due to its exceptional state of preservation. A thin layer of patina has developed on the case over time, showing how it has been untouched over the years. Furthermore, all hallmarks are crisp and present. The watch even retains its green caseback sticker, adding another layer of collectability.
