Watch is 6" including wrist band. Slight water damage indicated by staining. Model appears to be "Nancy". Runs and keeps time perfectly. Thanks to all of the quick input clarifying these details. I joined principally to add the 4AB movement to your database, as I could not find it through search and thought it might be of value to other site users.

Much older than the 40's. I'm thinking more like 1929 based on the style of the watch and the shield date code on the movement. If it is my eyes and the symbol is the Omega, then the date would be 1930 in a 1931 casr which would not be unusual. The band would have been changed at least once if it was worn alot.
Looks very similar to to the Nancy shown here. http://www.mybulova.com/vintage-bulova-watch-ads?title=193

Based on an ebauche by Peseux, the 90, Doc says it was made before '32.
Used by many notable makers, including Blancpain (Rayville) and LeCoultre-Piaget. I wouldn't be surprised to see it pop up under other luxury brand searches, although I just went through quite a few and found nothing further.
