The seamaster 300 is amongst the most famous dive watches created and was used by the Royal Navy for many years. It is the basis for the current omega dive watch 2254.50.00 although i prefer the original. It is incredibly difficult to find an original one of these as the majority are franken watches/ fakes. You certainly have to do your homework before buying one of these. I bought this one from my good friend 'The Master' who now has a nice IWC Ingenieur.
