HELP! Unidentified vintage Omega from 1965, ladies watch

Better photos are needed, including of the inside.

A few wild but not totally uneducated guesses:

It’s not an Omega case/strap, it’s locally made
It is tiny
It isn’t all that desirable as often cocktail watches rarely are
It isn't worth a lot more than scrap as the scrap value is already pretty high.

Pluses:
White Gold is rarer than yellow for these
The blue stones may be sapphires (but not necessarily valuable)
It looks in good condition

Have you studied and identified the hallmarks? They can tell you a lot. If Swiss, my first point may not apply and it may have some value over scrap.
