In 1969, Rolex simultaneously launched references 6263 and 6265, replacing the first Oyster Cosmograph– reference 6240. The Cosmograph Daytona with screw-down pushers was in production for almost 20 years and was offered with both acrylic or metal bezel in either stainless steel or gold case.

From 1971, the dial correctly displays the “T Swiss T” designation at 6 o’clock to mention the use of tritium as luminous material for the indexes. In addition, a Greek symbol called Sigma surrounds the Ts denoting that the markers are in gold. In the late 60s, a group of Swiss watchmakers who were members of APRIOR (Association pour la Promotion Industrielle de l’Or) formed an official initiative with the goal to formalize the standards for the use of gold in watches by watchmakers – especially on steel watches since stainless steel and white gold are similar in colour. According to a US Patent Office Registration Certificate, the Sigma mark certifies that the goods are of Swiss origin and contain solid gold up to a certain standard as established by the Swiss statutory requirements which include the control of the use of gold, the specification of standards and quality that had to be met. This symbol was in used from 1970 for approximately five years before it was abandoned.

The present reference 6265 from 1971 is presented at auction as a full set; the watch is accompanied by its original box with outer packaging, the original guarantee dated October 25, 1973 and stamped by the Madrid based retailer Vendrell Joyero. The combination of silver dial and stainless steel bracelet give it a stealth appeal that makes it the perfect watch for any occasion.
