A collector I know has one of these watches with a BLUE! dial and the stubbies. There is no Seamaster emblem on the back, only the military engraving. The movement is obviously real, and he says he has the provenance?
Hi Glenn,
I've never seen a 60's/70's SM 300 in Blue, although I have seen genuine speedmasters that have faded to Blue, so I suppose it is a real possibility.
I don't think Omega have EVER issued a dial with "stubbies", so to be honest I would bet on a Blue dial with stubbies as being a re-dial at the very least.
There IS a blue Semaster 120, but this has a very different dial with applied markers.
An option, open to your friend, would be to to get Omega to issue you a "Certificate of Authenticity". It's easy, doesn't cost much & will prove beyond doubt if a watch is genuine or not. ( at least , it was genuine when it left the factory ) These certificates usually list the country of the dealer which got the watch, so if it IS a genuine SM 300 & was issued to anyone except a British dealer / miltary, then it's likey to have been "converted" to a military watch ( but not actually having been a military watch ).
Mine passes all of the authenticity tests but has no military engraving.
I'm glad to hear that, & to be honest, I reckon MOST SM 300's weren't miltary watches. So that's OK.
As I wrote above, I'd certainly get a "Certificate of Authenticity" from Omega for your watch. It will give you peace of mind ( if you need it ) & should you ever decide to sell the watch, should increase the value dramatically.
All the Best
Steve
