Need help evaluating Omega DeVille Prestige gold

I liked this watch, I plan to buy it, I need help in assessing its real value.
Request to experts to indicate what their market value ???

18k gold

Look for eBay sold listings. That's about as reliable as it gets.

What has your research uncovered @Alex_bon?

Hard to answer for an older Omega like this. Are you buying it from a reputable preowned watch dealer? I’m guessing no original box and/or papers? Any info or documentation on how recently it was serviced?

The previous sales on eBay approach probably won’t work so well for an older Omega that isn’t a Speedy or Seamaster. Aesthetically the watch looks to be in decent condition. A new model Deville with an 18k gold case would probably be in the low 5 figures. For this one, I personally would think 3-4k might be a reasonable price but I would follow the old adage to buy the seller not the watch. JMO

One more tip for you …. I’d guess this watch is maybe 25 or so years old. Try posting this question on the Omega vintage board and maybe you’ll get more replies.

The OP is unlikely to get many replies no matter where he post this... because it's not really the sort of thing that collectors go after, nor, from the look of it, was it all that popular in the first place...

There are some sold listings out there. Both on eBay and at auction houses.

He knows what the seller is asking... or, as I am starting to suspect from his other posts, is a dealer/seller, coming here to ask us to evaluate watches he is buying and selling.
