The Rolex Daytona 6263 is the rightful successor to the 6240 reference, because, unlike the 6265, it preserves the bezel with the black insert, a characteristic which made its way into the common imagery of the sports chronograph.
Produced since the early '70s, both the 6263 and the 6265 references remained in production until the late ‘80s, when Rolex introduced its first chronograph with automatic movement, the 16520 reference. Given the extended period of time in which they were marketed, the 6263 and the 6265 are perhaps the two Daytona references par excellence, which have helped make this watch a real status symbol, in addition to Rolex’s flagship model.
The watch offered in this auction represents the most iconic and desired version by collectors, with the "Panda" dial and Daytona printed in large red characters, called "Big Red", which was introduced in the mid ‘70s above the hour counter. The watch was consigned by the first and only owner, who carefully preserved each component in excellent condition.
