Bulova 1957 American Girl

Bulova L7 year model, 10k Rolled Gold plating. The watch strap is original, however, I have not been able to find a match on the Advert database. Closest picture matches are either an " American Girl " model or a "Dolly Madison" model. This watch was my grandmother's, who passed it on to my mother, who passed it on to me. The watch needs the crystal replaced, and the winding mechanism repaired. I have not opened the case (afraid of damaging it), but would like to identify it, in order to send for restoration.

Thank you, Paul
