CONDITION REPORT: All original, the dial is mint with a tiny portion of the Fat T missing from a misprint and not scratched. The green lume is typical of the latest 60’s and big triangle dials (especially military ones) and why the lume of the hands appears a different color. Both are original. The case is worn, but appears unpolished and fixed lugs are still intact. There is a scuff with some oxidation on the upper right lug.

The military SM300 watches had engraved numbers on the case back, the letter 'T' for Tritium in a circle on the dial and solid non removable strap bars instead of the usual spring bar.
In several details, the British MOD ordered from Rolex the Submariner ‘Milsub’ 5513 (later became 5517) with the same specifications as these Omega Seamaster 300. Therefore these Rolex Submariner models are very unique and look very similar to these Omega Seamsters. Firstly, the atypical sword hands were copied as well as the seconds hand looking identical to Omega and being the only Rolex to carry this hand. In addition the circle T printed on the dial make thse easily recognizable as well. The 60 min graduations on the bezel and the fixed sipring bars were also inspired from this model.
Essentially, these are the predecessors to the milsub, which end up as a copy of the Omega SM300 military.

This watch is accompanied by an Omega archives extract confirming its production in 1968 and military issue and delivery to the British Royal Navy (Issued 1970)
