Any information you can add is appreciated.
Looks to be in wonderful condition.
A very nice early 1920-21 Bulova Lady Maxim would be my call.
We have yet to really understand the serial number dating for the period between 1919 and 1922.

Thank you, yes, it is in wonderful working condition. It has been in my family for many years. I am hoping to learn more about the history of this piece. To me, it is a work of art, very beautiful.
Welcome to mybulova; a beautiful heirloom watch. I agree with Stephen, most likely a 1920/21 Lady Maxim. Ladies Bulova watches during this time frame were seldom offered on this style band. Your band is a newer replacement, but of the same end connection as an original.
A really early Bulova watch and in excellent condition. Below are 2 ads from the database dated 1921. Not an identical match, but close.

Nice old survivor, for me, nothing better than than an heirloom watch. Very little history available on this era of watches. I would agree with an ID of:
1921 Bulova Lady Maxim
1921 Lady Maxim works for me too.
1921 Bulova Lady Maxim
FLAG !!!
By case s/n this one should be a 1920.
