Omega Seamaster 300 British Royal Navy issued ref. 165.024 Mil Spec Circle-T Dial

This historically important, military-spec Omega Seamaster 300 was issued to the British Royal Navy in 1969. It features the signature twisted lugs, a fully graduated 60-click bezel, a signed screw-down crown, and fixed spring bars — a design preferred by the Ministry of Defence. When paired with a one-piece nylon strap, this setup significantly reduced the risk of losing the watch due to spring bar failure.

 

The engraved case back bears the military branch code, issue number, and year of issue — key elements that highlight its service history. The watch's fixed bars between the lugs ensure your wrist companion stays secure, even in the heat of battle. The bezel is still in great condition, with no major defects or cracks.

 

This “Big Triangle” dial, combined with the broad sword hands, enhances legibility and features a gorgeous pumpkin-colored patina on the lume. The use of tritium on the hands and indices is confirmed by the circled “T” on the dial — a detail found only on true military dive watches.This cool tool is fitted with one of our Bulang and sons single pass nylon straps

 

Powering this cool tool watch is the automatic, red-gilded Caliber 552 movement, which has been fully serviced by our watchmaker. Fully serviced and ready for the next mission, this Omega military tool watch is as collectible as it is wearable.

 

Built for blokes who don’t flinch at 200 metres and issued to those who actually earned the right to wear it — the Omega “Big Triangle” Seamaster isn’t just a looker, it’s proper military kit

They’re rare, rugged, and ready for duty. Don’t dither — this one won’t hang about.⚓
