Need help to findout what model this watch is.

I have been looking everywhere for something similar to this but i cant find any info about it.
Anyone recognizes this model?

This is the only picture i was provided with, sorry for the poor quality and lack of serial number.

Thank you.

Case looks rose gold. Crown looks yellow. To match. Might have to find a generic as Omega hasn’t made rose gold anything since the 60’s

Yeah this looks like a pick and mix of a few watches and refinished dial.
If you can get the reference number from the inside of the case back and then take a look here

Made a trip to the watch store, still not sure how to interpret or input the digits on a search engine.
Would appreciate your help again.
Thanks.

The reference of this watch would be ref. 2684 from the mid 50s
—> I think it was called Tresor.
—> the movement calibre 266 seems legit/correct for that kind of reference.

But the dial is off in my non-expert opinion.

Through a quick search I didn’t find any with the star on the dial and in my eyes the position of the „Swiss made“ marker is wrong as well. Shouldn’t that be below the minute marker closer to the edge of the dial?
The star is usually on constellation models from the 60s and also below the model name. And not below the brand name.

The crown looks off/could be a replacement and I don’t think the hands are original either. By looking at other similar examples.

So my concern would be about the authenticity of the dial and the hands and the crown.

the markings on the inside confirm that it’s a solid gold case 18k and there is also the Swiss Helvetia stamp visible next to it.

The only informationi have is that this was bought in either Portugal or Venezuela in the 50s

Ok 50s is possible with the reference number but I am pretty sure there has been some stuff done to it afterwards.

but with the ref. 2684 and the calibre 266 you can research it and find out more about your watch.
