Case appears to be Crusador, however it houses a 13AC calendar movement that is stamped with a shield and a lighter "T". The dial cutout for the date at 3 shows original lume in the beveled window on top and bottom, indicating the window was present when the dial was painted at the factory.
Watch shows very minimal wear and was purchased by me as freshly serviced. It is running, keeping perfect time and the date changes at midnight.
Based on research, the only known examples of a early 1930's date window Bulova are this one, one in an apparent Apollo casing with a 10AC movement owned by mybulova admin (Stephen) and one (possibly 2) possessed by the Bulova Museum. I suspect this watch never made it to market, perhaps due to the Great Depression or Swiss Patent or patent rights issues.
I personally have no doubt this is an original Bulova, and for me a once in a lifetime purchase.. What do we call it? Is it a generic Calendar or a Prototype? It would be a shame to toss it into the ID Unknown drawer.

Bob, does does the date window have a bevelled edge?
What I find iteresting with yours is that you can see the top and bottom of the 3 on the dial. It's almost is if they seleted a few random watches from a pile (different models), cut the date window hole and through in the 10AC, 13AT movements to see which one looked better. I seriously doubt they mass produced these. I've not seen two the same.
I'm good with a general Calendar ID.

Wonderful find. The calendar window is a bit odd; odd that the print looks to continue down the bevel, so perhaps done after it was cut out. It does feel like a prototype, but still very cool.
As for the museum model, that one came through my hands years ago. Movement is the 10AC, stamped 1932.
