Vintage De ville Opal dial

I just picked up this vintage Opal dial De ville (I think) with a white gold bracelet. Couldn’t find any details on it online. Anyone knows any details on this watch regarding reference numbers?

Did an image search and found a Piaget and Universal Geneve that looked the same. No Omega

Reference number on inside caseback. Find a local watchmaker to open the back if possible

movement if hand wound could be a 6xx caliber

Not sure if 18k white gold.
Could be also silver.
Is there a any Hallmark in addition to the 750/18k?

Hello…

Did you even look at the pictures?

May I ask what makes you think I didn't?

This may have something to do with it. 😀

I asked beside those visible marks 18k/750 - could be it is on the other side of the clasp (which might be not visible on the other pictures posted by the OP) where there could be a potential different hallmark.

If it is 18k solid gold i assume there would be another hallmark.

What could also be the bracelet is just is plated.

There are other listings with the same marks for similar watch models stating it is solid gold - even though there is another hallmark stating "WG".

Having that said I can fully understand the OP thinking it is solid WG but it might be also only plated.

So would be great to have a final outcome on this and the OP maybe have it checked at a Jeweller / Watchmaker if he wants final clarification on the bracelet being solid WG.

Greetings, would you sell it?
