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.

Preserved in excellent condition, the present watch is an extremely well-preserved example with crisp edges and sharp lugs. At first glance, this watch look like a well-reserved, typical Cosmograph Daytona with a "big red" dial. Further inspection of the caseback reveals more as it shows an engraving which reads "Military Forces, Officer's Barracks". Made for the Libyan army, the present watch is incredibly rare and one among a handful of known tool watches delivered with this inscription on the caseback. Most interestingly, the inside case back is repeated with the serial number, showing that the present watch was made upon special order. Furthermore, there is a small hole on the outer case back, near the "teeth". This hole was used to secure the case back when Rolex stamped the markings.
