Calibre 552 automatic (self-winding), 24 jewels, 19800 VpH, with hour, minute, and centre seconds

Case Material

Stainless steel with asymmetric lugs and fixed bars and Omega-signed screw-down crown, caseback outer engraved with MoD ’Broad Arrow’ above 0552/923, 7697, A/681/70, inner marked 165024 twice, and SP


Matte black, signed, Ω, OMEGA, AUTOMATIC, Seamaster 300 and fat encircled T, with tritium luminescent indices, Arabic hour numerals at the cardinal points


Presented in excellent pre-owned condition, in just the way you would expect to see a military Seamaster: with signs of age-related wear and understandable servicing. The original dial has a very attractive patina, the tritium markers have taken on a warm hue, the military encircled T has small losses, and the handset is a service replacement. The original acrylic resin bezel is in good overall condition with general wear and pleasing discolouration. The asymmetrical case shows use-related wear but is strong, while the military-spec screw down crown, together with the Omega-signed crystal, are likely to be service replacements – all consistent and expected of a highly desirable and rare, Naval issued, military watch.


2mm diameter, strap circumference approximately 200mm


Grey NATO-style strap


Sword-shaped hour and minutes, with diamond long point seconds


Accompanied by a red Omega-signed square box with red velvet base, with Omega Extract of the Archives confirming production October 22, 1970 and subsequent delivery to the British Royal Navy.
