My mom bought this watch for my dad in 1990 and he handed it down to me. She purchased it from a jeweler who no longer exists. As you can see it is quite clean so I assume it is a replica? I can't show the movement yet because I don't see how to open the part of the case to expose the movement and of course don't want to use prying tools. I wound it partially and it appears to be working properly but I don't know if I'm to touch the hands to set it, or if there is another means. I appreciate any help.
