I think this one might be destined to go down as an unknown. There are several in the database from 1928 that are similar or identical to it. This one looks the most like it.
The case is 14K gold filled, marked "Bulova New York" with a June 10, 1924 patent date. The movement is a 15J, 6AF which is consistent with the other unknowns in the database that I referred to above.
It runs and keeps time.
A lovely watch, but Unknown. It is close to the Debutante of which 5 engraving versions exist. This is one of them.
Radium dial says "ladies sports watch". Engraving is close to Debutante, but not an exact match to available ads.
Tentative Debutante or unknown for me.
I agree this looks like a ladies sport watch.
Unknown for now
Nice one Tom, I like the bracelet. 1928 Bulova Unknown
