In 1969, Rolex introduced the references 6263 and 6265 in steel, 18k gold, and 14k gold reserved exclusively for the North American market. Both models are produced until 1987, with an estimated total production of the reference 6263 reaching 24,000 in steel, but ten times less in gold.
Gold Daytonas were powered by movements certified with the COSC official chronometer certification, which was an unusual feature for a chronograph of that period. Consequently, dials fitted on such examples, such as the present watch, bear the designation "Chronometer" at 12 o'clock, and "Cosmograph" above the 6 o'clock.
Created in 1973, the COSC (Contrôle Officiel Suisse des Chronomètres) is a non-profit organization founded by five Swiss cantons, with headquarters in La Chaux-de-Fonds. It delivers the "chronometer" certification of each watch sent to its laboratories that reaches the required standard. The performance of each movement is monitored for 15 days in 5 positions and at different temperatures. This means that certification is granted to individual timepieces, not to a model or series.
The present watch appeals both as a true sport watch and a status symbol, a rare example cased in 14k gold.
