Found today... Alden's 1955-56 Winter Catalog (High Res sent to Admin for databasing)
Check out #9... Senator.... but see at the bottom of the description PLAIN BEZEL = "Champion" Absolute proof of bezel variant names... well... to go along with all the others.
Also... look at the Martha Washington 21 Jewel... as this was 1955 Bulova had already lost the Academy Award lawsuit.... but... heh.. must have had a pile of those cases left over as it's pictured with the Martha for sale!

So.... how many different watches can we name the "Senator"?! hahah.... the marketing department sort of overextended themselves there someplace.
