Chap I worked with was a total watch nut, constantly buying old watches on fleabay. Came into work with an Omega, a mechanical one from just before they went electronic. Paid £600 for it and took it to a hourologist to be serviced. Bloke took one look, asked if he wanted to sell it. “Bloody hell, I've only just bought it. Why?” bloke says, ”I've got a customer who'll give you £3500 for it right now”
Looked not unlike yours. Can't say I like the styling of those old Omegas, but they're nice watches. It's the fact that they are precision instruments, not mass produced timepieces designed to be just thrown away. Not that that's a problem, I currently wear a G10 MWC watch with Tracer markers that cost £90. Big problem is it's not waterproof, but it is amazingly accurate, to a couple of seconds over a six month period. Good watch, and if I was travelling abroad, then I would only take cheapo ones, in case unsavoury individuals feel that their crack habit needs feeding.
