Pretty average pocket watch. Would be worth a few hundred if it ran, but usually costs a few hundred to get them going if they're broken.
John, you can unscrew the back and look inside to see the gold content of the case.
Most likely it will say ROLLED GOLD PLATE, which is a thin layer of gold rolled onto brass or copper. It's more durable that gold plated, but not really very valuable from a gold content perspective.
Either of you, if it says something like 14K GOLD or 18K GOLD, then that is a solid gold case and is quite a bit more more valuable.
Oh, and look closely on the fitting of the chain for gold content there. It's going to be stamped somewhere and tiny, so get a magnifying glass.
Chains were often purchased separately and could be more valuable than the watch.
