37.5mm diameter
Offered by the original owner, this fresh to market reference 6263 was bought at an official Rolex retailer in Hong Kong in the early 70s.
References 6263 and 6265 were launched in 1969 and succeeded the outgoing 6240, the first Oyster Cosmograph model. Thanks to the redesigned screw down buttons and crown, these models were now guaranteed water resistant for 50 meters. The most striking detail of this Cosmograph model is the dial. Over time, it has turned from black to a harmonious and rich chocolate brown tone, contrasting against the white accents. It is remarkable how the dial has aged in such an even manner. Quite interesting to mention that the inside case back has been hand engraved with the full case number between “Patented” and “Stainless Steel”, like mostly seen in Rolexes delivered to Worldwide Minister of Defence or private companies (e.g. Comex).
Another example has been sold by Phillips Geneva in “Geneva Watch Auction:One” sale lot 188, featuring a similar tropical dial.
Its gorgeous appeal, makes this timepiece today an extraordinary treasure even for the most demanding collector.
