References 6263 and 6265 were both launched in 1969, replacing the first Oyster Cosmograph model 6240. The yellow gold Rolex Cosmograph Daytona with screw-down pushers was in production for almost 20 years, and it is believed that approximately 2000 pieces were manufactured.
The reference 6263 and 6265, were nearly identical in almost every way with the exception of their bezels. The 6263 was fitted with an acrylic tachymeter bezel, while the more sporty 6265 featured an engraved metallic tachymeter. As these bezels were easily interchangeable, oftentimes customers would request their dealers to replace the bezels based on their sensibilities when originally purchased. Research finds that the original owner indeed requested the original bezel of this 6265 be replaced with the 6263’s acrylic bezel prior to purchasing the watch on March 19th, 1987. Fitted on its original riveted Oyster bracelet and accompanied by the original Rolex punched guarantee and sales invoice, this watch is sure to please the discerning collector.
