My father recieved this watch from his Mother for his Birthday in 1943. Therefore watch should be 1943 or earlier model.
Inscription on back says "14 K Gold" * " 6122928 ". Sorry for the bad photo. If too difficult to indentify with this photo, I'll upload another later but this is best I have for now.
At this stage not looking to restore yet but more trying to learn about this model and record this part of my father's life.
Click on the Information tab at the top of this page and click on Vintage Bulova Ads. Start at 1940 or earlier if you want & look at the watches in each ad. Select the watch that looks like yours in every detail and you will probably luck out & ID your watch yourself.
Good Luck! Post a pic of your watch when you find it.
