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 1970, 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. The present yellow gold reference 6263 Daytona is in exceptional “new old stock” condition, retaining its original and extremely sharp factory finishing throughout. The case back even retains its original green factory sticker. The unworn case and bracelet have developed a pleasing, rainbow-toned tarnish, further enhancing its character and underlying its great quality. With a coveted R-serial number, it was manufactured at the very end of the reference 6263's production in 1987, immediately preceding the launch of Rolex’s first self-winding Daytona. Extremely attractive with timeless style, it comes complete with its original punched guarantee, booklets, and presentation box. A time capsule in to Rolex’s past, it’s a rare opportunity for the discerning connoisseur.
