(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!
Thank you for posting your grandmothers watch. The watch appears to be a 1960 Bulova Goddess of Time "W". It appears to have had the bracelet replaced at some point as is common as you can see from the original Bulova Line Book from 1960. This was a ladies watch and would have been quite expensive in 1960 ($525 in todays dollars) although it was not uncommon to give watches to girls when then graduated high school.
As a side comment regarding Bulovas for teenage girls, I have a large 1967 Fall Season SEVENTEEN fashion magazine, and hoped to find some watch ads. The only color full page ad was for Caravelle, with Brit inspired wide brightly colored textile watch bands on modern round flat gold cases, the approach was intended as graduation presents.
