References 6263 and 6265 were both launched in 1969, replacing the first Oyster Cosmograph model 6240. The yellow gold Rolex Cosmograph Daytona with screw-down pushers was in production for almost 20 years, with roughly 100 pieces made per year.

The present watch dates to 1978 and is a beautiful example of this iconic wristwatch. The gold colored dial is enhanced by the “tropical” subsidiary dials, which have aged beautifully, uniformly reflecting a subtle chocolate brown tone. The “T-SWISS-T” designation at the lower edge of the dial by the 6 o’clock indicates the use of tritium for the hands and luminous hour markers, which have aged to a warm and pleasing cream-colored tone.

Adding to its exclusivity, this rare 6265 Oyster Cosmograph is in 14-karat gold, which was offered only in the North American market. Furthermore the typical metal bezel found on the 6265, had been replaced likely at the time of its original sale with the acrylic tachymeter bezel found on the 6263 model. The bezels for both references were easily interchangeable and fit both references, and its appearance on this example could have been the conscious decision of its new owner to make the watch look less sporty.

This elegant chronograph is preserved in exceptional condition, showing few traces of careful wear over its lifetime. The rarity of the timepiece is highlighted by the 14k gold case, tropical subsidiary dials, and original 14k gold riveted bracelet. It is a wonderful addition for the collector with discriminating tastes.
