Rolex Ref 6263 Daytona, Sigma Dial Circa 1975, Full Set (Original Box & Warranty Papers)
This is a rare and complete Rolex Ref 6263 Daytona in original and very attractive condition.
This Daytona features the desirable black “Sigma” dial with the Greek symbols on either side of the “T Swiss T” signature at 6 o’clock. The Sigma dial was a feature of luxury Swiss watches in the first half of 1970s when the guidelines by the Swiss watch industry association APRIOR suggested that dials bearing gold markers and hands be stamped with the Sigma notation to distinguish them from base metals. Since this was only a suggestion (rather than a rule) and the notation was rarely understood by customers or dealers at the time, the convention was used sparingly. Sigma dials were eventually abandoned around the middle of the decade. Nevertheless, on Rolex steel sport watches the rarity of the Sigma dial also serves to authenticate the age and the originality of the dial, because there were no service sigma dials issued after the 70s.
This Ref 6263 Daytona is in great condition with full proportions to the case and sharp lugs. The case was carefully taken care of and was not subject to excessive polishing. The model/serial numbers between the lugs are clear and unpolished.
The dial is also clean, with light patina that is consistent with age. There are no signs of pitting or moisture damage on the dial, but interested buyers should note that lume dot at 9 is missing and the one at 3 is slightly chipped. This damage is very common for sports watches of this age, and we think the lack of restoration is part of the charm of this watch. The tachometer bezel insert is original with only faint hairlines and no chips.
The Valjoux Cal 727 movement on this watch is spotless: clean and free of any scratches or signs of age. It has been tested and keeps great time with all functions working as they should.
This watch is further delivered with original box and papers, which adds to the desirability and sustained value of this rare example.
Parthian Watch will ship this watch with a bonus gift: a custom-made ABP Paris square alligator strap worth $375 (featured in the last 2 photos) to give the watch an additional wearability option.
