Vintage Bulova Watch

This is very old watch by my grandmother. I only had worn once is stretchy 10 kt plated. Work perfectly. It has slight dark spots and I am not sure how that can happen because I had this stored for over 30 y. I accept offers. I hate to let this go but I never use it. Hope someone out there will enjoy and blessing as well as my grandmother was such a beautiful soul. Is a wind up kind no battery needed.
