Wondering what it is and if it is worth getting repaired.
Its great not only that you bought this watch originally, but that youve kept it. I would get it back running and use it, but im not 100% sure what the comment above about Omega using whatever comes to hand is about, but my experience of Omega service in both the UK (at STS) and at Bienne is that they will do a great job and also what you want, unlike say Rolex. Omega USA tho I would not trust, maybe that's what ulackfocus is saying above?
You have a number of choices about how you proceed, but just letting any watch place loose on it is not ideal. It all depends on where you are in the world as to whom you would trust.
Well I'm not really worried about the dial or hands. They are the originals and in very good condition. Could see no reason for any replacements. Have a quote from a reputable watchmaker, Just have to decide which of my three old watches I am going to get fixed first. The Omega is of course expensive, the Zodiac Sea Wolf less so, but worth less as well. The last watch I bought while in the Navy is a Brietling Cronomat with the GMT second watch. About the same money to service as the Omega. From what I can tell about the same vaulue as well. I will admit I was a bit surprised to find out the Omega was an odd one.
well as Rick from Pawn Stars will tell us, the value is in the dial and hands,
I think as a rule of thumb thats fine, but some brands and some models are rare enough for it to matter less than others. Rolex modern dial, hands or new bezel on a 1665... nightmare of wiped value and you crying in your beer, Omega modern dial/hands/bezel on ploprof... fine and easier to sell than a beat up watch would have been IME. Of course, that may change in the future, but thats the way they are for now...
