Yellow Metal case and band. Back of case, "Bulova" with a shield (not like any of the date codes). Serial Number then, "10K Rolled Gold Plate". Nothing inside the case back but jewelers markings. Metal band matches perfectly and appears contemporary to the watch. Bottom of clasp has a sort of triangle symbol with, ""1/20 - 12K Gold Filled", and "Pat. 2,097,055, U.S.A. The patent was issued in 1937. So this band probably was added later....Movement is clean and runs well. Dial needs the gold "numbers' re-guilded. A really nice running example. Appears to be a 1936 Bulova Beacon........
I just love the black dials from this era. I would agree with Beacon like this one https://www.mybulova.com/watches/1936-beacon-9731
