Yellow gold plate w/stainless back. I really like the looks of this one. Great lugs and subtle stepping of case sides. Case and movement both marked "L3". Super clean and running accurate as received on a "Flex-Let" period replacement band dated 1-53 that's just as nice as the watch.
1953 Bulova Byron "Featured on TV".
Regarding the ad call-out of "featured on TV", an interesting fact worth noting: The world's first television commercial aired on July 1, 1941, before the beginning of a baseball game in New York between the Brooklyn Dodgers and Philadelphia Phillies. The commercial aired on NBC's WNBT-TV, was only 10 seconds long, and was an advertisement for Bulova watches. It cost the company a total of $9 ($157 in 2020 money)..

Bob - Bulova has the video in WIDEN, their archive database but it's also available on you tube. Here's the description in WIDEN: The first ever TV commercial, a Bulova ad. The commercial played before a Brooklyn Dodgers–Philadelphia Phillies game at Ebbets Field in Brooklyn, NY. The NBC-owned station WNBT in New York aired the first legal commercial in television history. Advertising was banned on TV until the Federal Communications Commission gave commercial licenses to 10 stations on May 2, 1941, to go into effect July 1. WNBT was the only one to air an ad on that day.
