The present watch, manufactured in the final year of reference 6263's production, is characterized by its extraordinary condition. Most probably unpolished, the case retains incredibly crisp hallmarks and sharp edges. One can even see a clear definition to the case where the right edge becomes flat and extends towards the crown. The watch is furthermore accompanied with its original guarantee, stating the watch was retailed at Rob. Engstrom AB, Stockholm, which a stamped with country code 267, for Sweden.

The watch retains its green factory sticker to the case back, original pushers, bezel and period correct bracelet, which is fitted with 71 end links and is stamped K9 for 1986.

Reference 6263 was introduced to the market approximately in 1969, and ceased production in 1987. While the reference was mainly cased in stainless steel, very small amounts were also manufactured in yellow gold. Reference 6263 was in production for almost 20 years, yet scholars approximate that no more than 2000 examples were cased in gold.

From the early 1980s and onwards, gold Cosmograph Daytonas featured a movement number engraved on the plate, behind the balance wheel. Research suggests that this was related to the officially certified chronometer movement. Around this period, Rolex modified the dial layout for gold versions, and the "Officially Certified Chronometer" designation was printed on the dial, which we see on the present example.
