Bulova 1938 Buckingham
I believe this is Practitioner, but the only advert I can find is a one for 1942 which has a different movement (10AX). the dial and case looks the same. But the movement is a 17 J 10AE which according to the movement info on the db is a 1940 movement. I haven't received the watch as yet and the picture of the movement is not clear enough to make out any date mark.
But the case is marked Bulova with a shield after the name. plus serial number 8712886 under that its marked 10K gold filled
