The present watch is a fascinating example of the collaborative efforts between a manufacturer and client - in this case the Pakistan Air Force. This watch uses Omega’s Railmaster case and movement, however it is the Seamaster name that is applied to the dial and engraved on the case back. It is not clear why the Pakistani Air Force would specify this unusual combination, however it could be explained in part due to the Air Force’s requirement for an anti-magnetic watch. The Railmaster, with its inner Faraday cage, protected the movement from the adverse effects of magnetic fields. During the late 1950s and early 60s, many companies produced tool watches that could be used in magnetic environments, including Rolex with their Milgauss and IWC with their Ingenieur.
The present watch is preserved in its original condition, with signs of wear illustrating its use as a military watch. The case back is engraved “P.A.F”- the acronym for the Pakistani Air Force. The dial, with broad arrow hands, have aged to a wonderful shade of espresso, as have the indexes. Even the crystal is original with the minuscule Omega logo found at its center. For enthusiasts of military issued watches, this Omega is an extremely rare treasure that is certain to delight and excite.
