I'm guessing this one is a 1949 ladies Bulova. It has a 5AC movement with the "A9" date code. The case serial number starts with an "I" which is the 9th letter in the alphabet but I don't know if that means anything or not.
Can you pin down the model ID on this ladies Bulova for me? I think it may be a "Suszana" or something like that. I found a blurry ad that looked close to it but I couldn't read the name very well.
