Wading into the deep end of the watch box again today, 1929-1931 “Prentice”. Bulova movements from the 1920s-1940s have date code symbols denoting their production year. This one is a bit of an oddity in that it has date codes for both 1929 and 1930 — i.e., the symbols located up by the crown that look like a shield (1929) and something similar to an omega character (1930).
