Here is what I think is a 1953 Bulova Commuter. Like this one based on the 1953 date which corresponds to the 1953 ad provided. It appears in 1955 and later this became a Mr. Universe.. https://mybulova.com/watches/1953-commuter-827.
The case and casebook are 10KT yellow rolled gold plate with an L3 date code. The lugs are hinged and swivel. The dial is silver with applied yellow gold 3,6,9,12 hour markers. The movement is a 21J 7AA caliber with an L2 date code.
