Kembery Antique Clocks Ltd has dated this piece to the 1950s.
The Ministry Of Defence subsequently recalled these watches to change the substance on the dials to Tritium, hence the circled 'T' underneath the Omega logo on the dial. These rare watches are easily identified by the 'Fat Arrow' on the dial as opposed to the 'Thin Arrow' on the majority of military watches. The watch is complete with the anti-magnetic inner case cover that made sure the timekeeping was unaffected by the various magnetic items a pilot would come into contact with. Case back is marked with a broad arrow, NATO codes and batch/order numbers.
Case width 37mm.
