What is the material and value of this Art deco watch?

Hi there,
I’m concerning the material and value of this watch, which is my grandma’s vintage watch. Thank you for your guidance if someone would answer.
Best,

I think those are almost certainly diamonds.
You need a jeweller to appraise that. The gold's value is determined by purity (18K) and weight. The diamonds by colour, cut, clarity and carats.
Even if someone here had the experience to give you a valuation, they would be unable to do so without examining the diamonds using a loupe.

The diamonds are real and there are quite a number of them. However. They are med. small to very small. Hard to tell size of diamonds. Larger could be .25 carat. .25 is 4mm wide. I’m sure they are nice quality, but overall. This was sold more as a diamond and gold bracelet piece vs. an actual watch even though it is.

You could get it appraised by a gemologist and insured for replacement value, but you would never get that price on resale.

If you’re selling. Most likely buyer would be a woman for a jewelry piece, but few and far between.

Shop it around at decent jewelry stores after the appraisal or eBay no reserve and take your chances
