I am pretty sure this is a Dictator model.
Inside of case back reads:
Pat. June 10, 1924
Bulova
14K Gold Filled
New York
Movement is a running 17 Jewel 8AN movement
I dated this to 1928 based on the case serial number and the movement is a 1927 date based on the square date code.
All of the hands are replacements that are incorrect and when I send this out for service I plan to get the dial refinished to orignal with lume and add a pair of the cathedral styled luminescent hands to go with it.
I'm good w/ Dictator. I love that dial...I wouldn't touch it, short of a light, careful cleaning....but I have a bunch of old watches with dials that other folks may redial as original or exact match. For me, I prefer the original vs a new looking, as original redial...
