Rolex Daytona 6263 Big Red, `80sStainless steel round case, n.7627399, black acrylic bezel, round screwed pushers. Black dial, white counters, applied indexes. Hand-winding movement, cal. 727. Stainless steel Oyster bracelet 78350, deployant stamped I10, 571 end-links. Size: 37 mm. Notes: The Daytona 6263 was introduced to the market in 1969, along with its twin reference 6265; they remained in production until the late `80s, when Rolex launched its first chronograph with automatic movement, reference 16520. Given the extended period of time in which they were marketed, the 6263 and the 6265 are perhaps the two Daytona models par excellence: the watch offered in this catalogue represents the most iconic and desired version by collectors, with the Daytona writing printed in large red characters, called "Big Red", together with the black acrylic bezel.
