Hello everyone. Looking to buy my first vintage watch and came across this Seamaster model. Asking price is 500 euros but negociable...unfortunately cannot see it in person as seller is not local. Apparently it runs ok. Should I or maybe keep looking? Thank you!

Case looks too polished for my liking. I think you can find a better Cosmic for 500€.

Looks fine, and the price isn't too bad. It's not a lot of money, so if you like it, why not buy it. I see you have been a member since 2019, so you'd might as well get started actually owning a vintage Omega, there's no point in search forever to worry about a tiny bit of polishing or $100 extra. Get your hands on an actual watch. Own it. Wear it.

Yeah, the price is not outrageous, but the polishing is pretty substantial: the top case radial brushing is gone. For me that feature is very important for the "Cosmic look". If you want a shiny Cosmic, then this watch is ok I guess. I like that it's a no-date model.

thank you for your input, i am still trigger shy because this came up, but advertised as 30mm? (might be a mistake though) and i think i like it better... what do you think?

Could be a reference to the size of the movement/caliber (as in the "Seamaster 30") rather than the size of the dial, which is probably closer to 35mm.

The "30" is also sometimes used to denote water resistance. See this thread:

Hello Omega Experts—what does the 30 in Seamaster 30 stand for? I've seen 30mm to denote movement size. I've also seen 30 METERS as in water resistant to roughly 100 feet?

They’re quite different watches. One very 60’s and traditional, one very 70’s.

Rather than looking at watches you stumble across it’s better to decide what you actually like and hunt one down.

contacted the seller and he confirmed the case size to be 30mm, caliber 681 and the caseback can not be removed (as in the movement is accesses through the crystal). my current daily is a 41mm Oris pro pilot and i am afraid that this would be comically small...at 35 i would have taken a chance

sound advice. i know i want Seamaster and I like the domed back with the seahorse. I am on a rather limited budget so stumbling across things is how I do it...i also want something that looks rather comparable to a contemporary 40/41mm watch

34mm is standard for 60’s men’s watches.
30/32mm is unisex/womens.
36mm is considered large (for the period).

Here is my 166.026, sand texture dial, 35mm with bracelet FYI 😀
That's a beauty. The dial on that even looks Cosmic😀
