The BULOVA "HIS EXCELLENCY," Model "LL," Circa 1951, 21 Jewels, 10 karat Yellow gold filled case... Ad illustrations cropped from the Fall Winter 1949 SPIEGEL catalog...
CASE(s) IN POINT: I would venture to say that as the "Excellency" and "Academy Award" models tend to overlap to some degree in BOTH model ID (by shared case...) and therefore also the crystal parts specified (likely due to a combination of utilizing currenty available cases from suppliers, and perhaps also for the sake of simplicity to a lesser extent?)
The men's (+ some ladies?) AA "AMPUS" and various His Excellency series tended to share some of the same watch case (excluding of course the flamboyantly stylized "custom" AA watch cases designed especially therefore, in 1949/50) "Alpha" namesakes, such as "SS," for instance... At least according to replacement crystal manufactuers, period catalogs...
