Dial number font is different/earlier than the 1923/24/25 adverts, so 1921/22 looks about right.
Model name or number is unknown to me at this time.
I bought this watch knowing it is an older Bulova needing a little help,very dirty. Thanks for any help identifying and dating. Bruce.
One of my favourate things to do is to clean these early movements up to see then shine and tick again. Best of luck with the restoration. Make sure to post some 'after' photos.
Dang, that's cool Bruce. Other than agreeing it's about 1922 I can't add anything either.
