DAYTONA MODEL, REF. 6263, CASE NO. 7'426'689, CIRCA 1983

Fresh to market and from the original owner, the present timepiece is a rare opportunity for the discerning vintage Rolex collector to acquire a very attractive 18k gold Daytona reference 6263 in original condition. A noteworthy feature is the four or five digit number (in this instance 10615) engraved on the movement plate above the caliber number. This number corresponds to the number given for the C.O.S.C. test of the movement at the Geneva Observatory, a characteristic found exclusively on the cal. 727 movements in gold cased references 6263 and 6265 watches from the 1970s and 1980s.

Reference 6263
Over the years, reference 6263 has become one of the most sought-after Rolex models. Introduced in 1969 as the sister reference of the 6265, it replaced the first Oyster chronograph, reference 6240. Fitted with the upgraded caliber 727 as well as screw down pushers enhancing its waterproof abilities, it bears the 'Oyster' designation on the upper-half of its dial and differed from the 6265 through its black bezel graduated to 200 units. The defining feature of the reference is undeniably the presence of the screw down pushers, which makes the entire watch look larger, sportier, and more masculine.
