ROLEX. A VERY RARE AND HIGHLY ATTRACTIVE STAINLESS STEEL CHRONOGRAPH WRISTWATCH WITH “TROPICAL” SUBSIDIARY DIALS
SIGNED ROLEX, OYSTER COSMOGRAPH, REF. 6263, CASE NO. 2’788’879, MANUFACTURED IN 1971
Cal. 727 mechanical movement, 17 jewels, silvered brushed dial, applied baton numerals with luminous accents, luminous hands, three subsidiary engine-turned light brown dials for constant seconds, 30 minutes and 12 hours registers, tonneau-shaped water-resistant-type case, black bezel calibrated for 200 units, screw back, screw down crown, two round screw down chronograph buttons in the band, stainless steel Rolex Oyster bracelet, case, dial and movement signed.
In 1969, the world sees the unveiling of references 6263 and 6265 in steel,18k gold and 14k gold, which will only be available for purchase in late 1970.
At their heart, the caliber 727 beats with 21,600 alternations per hour and the chronographs are guaranteed waterproof to 50 meters thanks to the redesigned screw buttons and crown.
The very first batches mount the 700 series crown, with the 5 point Rolex crown engraved on the outside and early steel models still feature screw-down push buttons in nickel-plated brass with a peculiar finish characterised by vertical ridges very close to each other, the so-called millerighe.
Estimates calculate that over a 20-year period, the total production of this model reached 24,000 in steel and ten times less in gold.This production is relatively high, compared to other manually wound Daytona models, and as aficionados well know, the case design can be divided into 3 distinct groups, or series. The first series was produced in very limited numbers, around 900 pieces for the 6263 and 1300 for the 6265. A distinctive characteristic is a fatter case compared to later series. The second series is defined by its thicker case and the final series sports the more modern-style case.
The dials of the first-series screw-pushers have the Oyster designation unlike the Daytona one, as in this example. It is impressive because of the integrity of all its components, for example, first series case, millerighe pushers, bezel, and hands.
What truly fascinates the beholder is the subtlety of its registers, which are incredibly bright and have a mustard tone or, as it is known in the Italian collectors’ circles, Terra di Siena. The final effect is quite unique and a perfect example of the multiform world of vintage Daytona; a true treasure for collectors.
