Omega Geneve 166.0202 any thoughts on this one?

I can’t properly advise because the photos are so poor but it looks like a standard mid 70s Geneve. 1012 movements are cheap and easy to service, so probably no problem with the movement.
The case and crown are probably alright and the dial might be okay but it’s hard to see.
Just remember that photos show blemishes that you probably wouldn’t notice when wearing the watch and, given it’s cheap, that might be okay for you.
Probably worth £150-200 ish.

Just realised that it doesn’t have ‘Geneve' on the dial, which surprises me a might flag up a potential problem.

Unless I’m mistaken, I think it’s a Seamaster ref - but it also came without the model name on the dial, so that should be all good.

Agree with the rest of the assessment - no idea what those two spots on the dial are but they would bother me. It’d have to be very, very well-priced to be interesting in my book as they’re widely available and don’t usually achieve high prices. Movement looks a little tired, but as Spruce said, nothing a service couldn’t fix. Factoring in the cost for one and the blemishes on the dial I’d say 200€ max.

Those two dots are from the dial feet poking from the back, someone probably jammed the dial on.
