This is a 70's-ish Volcain that was bought from (we think) Sears by my late grandmother and given to my uncle for his 16th birthday. For his 18th birthday, she bought him a Honda motorcycle, which he promptly drove under an 18 wheeler and died, while wearing this watch. I would like to restore it and give it to my mother, his sister. I know I can buy a NOS one from ebay for around $200. My questions is; is this one too far gone to mess with, and about how much would you think it would be? It's missing the crystal and the crown would have to be replaced. My main concern is that the back says "Base Metal" so I assume it's a pretty cheap watch to begin with.
