Grandmother's watch

[soccerguy]

I have come into possession of a watch my gran used to own, I know nothing about it. I would like to find out, if it has any value, it does need some work.

It says 18kt white gold diamond ramle swiss ladies watch, that is about as much as I know, Movement is unmarked. Very art deco with small diamonds and some blue stones? Back is marked 18C 0,750, serial number 951914. Bracelet has floral links. Watch in good condition but not running.

Is it worth repairing??
