(I know very little about watches, so please forgive me if I word things poorly!)
The back of the watch case reads “Bulova M0” / “10k rolled gold plate”
I don’t know what the type of strap/bracelet is called, but the segments stretch easily to fit over the hand; there is no clasp. The bracelet is presumably made of the same material as the case.
The watch belonged to my grandmother and was manufactured when she was around 12-14, so perhaps it is a model that was marketed toward younger ladies? (I don’t know if Bulova made such watches; again, my knowledge on watches/Bulova is limited.) I have not tried opening the watch as I don’t have the tools or knowledge to do so, and don’t want to risk damaging the watch. I would appreciate any insight I can get!
