Hi friends - I was hoping I could get a advice on this beautiful timepiece. History is I do not own it but I saw it at a store and tried it on and have been thinking about it ever since and it’s still available and hasn’t been priced as it was “in the vault”. I believe it’s a 145.012 cal 321. DON bezel seems to be in great shape. This is the only picture I have so I apologize.... I really liked the patina and it would be my first vintage omega, so want to make sure my first purchase is kept in-line with collector valuation. Any input on the watch and what it should retail for, collector price not crazy24 prices. Thanks for the help!
