In 1969, Rolex simultaneously launched references 6263 and 6265, the "intellectual offsprings" of the first Oyster Cosmograph - Model 6240 discontinued in 1969. The Cosmograph Daytona with screw-down pushers was in production for almost 20 years and was offered in either stainless steel or gold.

The present reference 6263 displays a stunning dial that has turned a beautiful rich chestnut "tropical" tone with age, and is distinguished by its impressive state of preservation. There is no telling how a tropical dial will turn, and this examples displays a richly saturated milk chocolate tone, with a darker shade in places granting it a somewhat "dégradé" effect. The luminous dots are furthermore preserved in excellent condition, round and without losses. The case as well is in remarkable condition, with incredibly crisp edges and full lugs.
