What a beauty, thanks for sharing your heirloom. Based on the crescent moon on movement bearing a serial number, paired with a case serial number starting with an "8"; your watch is a 1928.

This ad is from 1927 and shows a different dial. Dial appears to be a match to the case and number font matches ad. It's possible it is original/variant.
1928 Bulova Bernice, noting dial variation from ad and replaced crown.
I will change the date in original info above.
