BENRUS Ladies watch, vintage or maybe Antique????

My mother in law passed away couple years ago and she gave me her jewlery box, I tucked it away I my attic and forgot about it. 

Now with the holidays approaching I'm looking for ways to make money, so I went up to the attic and bingo!

These pictures were taken 20 minutes after I found it, so it hasn't been cleaned yet.

The winding button does not seem to work.

My question is, can you tell me the value, model and maybe year if you know it. Also, what should I do next with it.

Any response would be greatly appreciated.

thank you, [email protected]
