DAYTONA MODEL, REF. 6263, CASE NO. 5'951'377, CIRCA 1979

The present timepiece offers a rare and thrilling opportunity for the discerning Rolex collector to acquire one of the most coveted iterations of the Daytona, the reference 6263 in yellow gold. In addition to being extremely rare, this example stands out for its exquisitely preserved case, which features full and well-defined proportions, sharp hallmarks, and serial and reference numbers that are clearly engraved. Another noteworthy feature is the four-digit number (in this instance 5611) engraved on the movement plate in front of the calibre 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 of the gold cased references 6263 and 6265 from the 1970s and 1980s.

Reference 6263
The 6263 replaced the first Oyster chronograph, the reference 6240, and was first introduced in 1969 as the sister reference to the 6265. It had screw-down pushers that improved its water resistance, a distinguishing feature that also gave the watch a more robust and athletic character. It was also fitted with the upgraded Caliber 727, an evolution of the Valjoux 72. The reference 6263, a model that has since become an integral part of vintage Daytona collecting, was solidified as one of Rolex's most enduring and sought-after chronographs by its black acrylic bezel, graduated to 200 units, and the bold 'Oyster' designation on the dial.
