1932 ? Closest thing I found in the ads was for a 34 Miss Liberty but this is missing the engraving down beside the crystal like the Miss Liberty in the ad. Outside casde # is 277777 and the number on the inside of the case is 2206178. No patene date on the inside of the case it only says Bulova Quality
I was just browsing the movement list and the 4AL is only listed as 30 and 31. If this model remains as an unknown at least you will have a 1932 (T) movement for the list
Close match for a 1932 Bulova Miss Liberty although I think we determined previously that the diamond mounting was different.

OK not a Miss Liberty, I can confirm that the diamond mount is kite in shape and not curved.
Here's a 1932 advert, without a model name.

Advert found showing the style as a Bulova Dolly Madison valued at $42.50. Jewel count is off....but.....

OK 15 jewelled version is ok also.

1932 Bulova Dolly Madison is good match, perfect work Stephen
1932 Bulova Dolly Madison....only .50 per week!
