This is one of those cases that always sparks some debate. It was used for multiple watches. Your case matches The HE you reference as well as slightly earlier watches in the Db (1946) we have ID'ed as Statesman and also Director (Director appears to be mis-identified) .. The Statesman and Director models seem to have rolled into the His Excellency collection in or around 1947, but I don't think this face configuration did as I find no ads depicting it after 1946 as a HE. We have 3 watches identical to yours that I find in the Db, the one you referenced identified as His Excellency, one here identified as Statesman and the likely mis-identified Director..
I'm on the fence. It appears that the His Excellency you reference was ID'ed early on in mybulova history with no ad evidence, rather by date. It looks to me like the 1947 and forward HE in a rose gold case had a fully black printed dial like this one, with ad evidence. Unless there is a second yet to be identified one with the same dial as the Statesman seen in ad below dated 1946, or a HE ad out there I missed with your face. I'm thinking there was an overlap of names.
Without newer ad evidence identifying it as a His Excellency, I suspect subject watch and also the 2 others referenced are Statesman.
