Well this has certainly improved matters.
At the top is a before shot, with the original, mouldy looking lume. This wasn't doing the watch any justice so off it went for a relume.
And here's the result. To my eye it looks immeasurably better. Yes, it's no longer original, but this is a prime example of how a good relume can improve a watch.

Fantastic dials! More please!
Military = companion = broad hour markers
Technical = thin hour markers
Did I get this right?
Well never say never with vintage Omega, although the second picture you posted is a different reference altogether (seamaster 600 ref 135.011) and that crown is correct for that reference.
My feel is that’s a standard style service crown after the originals were discontinued.
Well I finally managed to snag one of the true Seamaster 300 Companions, ref 165.002.
A safe queen she is not. The crystal is cracked, scratched and crazed to hell, winding the movement feels like stirring gravel and the lume is minging.
Still, the case is pretty sharp, the dial is original and the main body is decent and the hands are correct and original. It’s not something I’d do on a whim but in this case I think a sympathetic relume will certainly improve the watch, along with a new crystal and service.
