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 delivery in 1967 to the UK and also that is was a UK Military issue watch.
