Help to identify this vintage Omega.

can you take some in focus in focus pictures?
Any idea if it’s solid gold or plated?
Is it working?

Otherwise I assume with value around £200-250

It looks like its from the 1980s give or take a decade. If I had to guess I'd suggest it is quartz but in that era I think they usually stated so on the dial. it could be hand wind I guess. You really haven't given us much to go on at all.

I’ll lay odds it is a calibre 1010, automatic wind, from the latter days of Omega, pre-Swatch days. If so, I have read that collectors generally aren’t lined up wanting to buy Omegas with that movement. My guess is it is gold plated, and from the mid 1970s or perhaps early 1980s. Until we see inside the case back and the mechanism, it is hard to comment further. As to value? Mostly sentimental, but if you want to put a dollar value on it, check eBay completed auctions to get an idea of what buyers are prepared to pay for similar watches.
