Rolex produced watches with “Fuerza Aérea del Perú” engraved on the case back for the Peruvian Air Force. Like other “issued’ Rolex watches, the case serial number was engraved both between the lugs, and inside case back. This exceptional military timepiece is enhanced by the rare “sigma” dial, with the Greek sigma designation flanking the “T SWISS T” signifying the use of white gold hour markers and hands. While the most obvious characteristic of FAP timepieces is the engraving to the case back, there are two other traits that define these watches. One is that the serial number - all or part of it - has to be present on the inside of the case back, thus linking together case body and case back. The other is a much subtler detail, and often lost due to the reasons mentioned above; on the opposite side of the back from where the FAP engraving is, these watches present an extremely lightly engraved military issue number. So light is this engraving that even a gentle polishing would irremediably erase it. Only a meager percentage of FAP watches still retain this number today, and this piece is indeed one of them, the number 454 still totally readable on the back.
