Throughout the 1960s and 1970s, Rolex received a number of orders for issued timepieces. These tool watches were usually delivered to the navy or air forces, aiding soldiers in their line of work. The Fuerza Aérea del Perú, or Peruvian Air Force ordered a number of watches during this period.

The present example, reference 6265, is one such special issued watch. The case back is engraved "Fuerza Aérea del Perú", along with a three digit code which is very lightly engraved on the bottom of the case back. Most of these three digit numbers have been rubbed out with general wear, yet this one remains evident. It is interesting to note that there are two small holes on the outer case back, near the "teeth". These holes were used to secure the case back when Rolex stamped the markings. Furthermore, the inside case back is stamped with a repeated inside case back number, another sign of a special order watch.

This remarkable military timepiece is furthermore fitted with a rare “sigma” dial, with the Greek sigma designation flanking the “T SWISS T” at 6 o'clock. Research show that this signifies the use of white gold hour markers and hands. This feature is correct for a 3.9 million serial number.

The watch is furthermore presented in excellent condition, retaining its original mk 2 pushers and bezel. It features sharp edges and a milled finish to the top of the lugs.
