Dear Slsummers, very nice watch you posted. The “Bulova Precision” dial signature is always in combination with a Marc Favre movement, meaning your watch is fully original. Favre was absorbed by Omega in 1955 so their movements must have been very good, hence maybe the “precision” on the dial. Dating your watch is very difficult since Bulova only introduced a logic on dating cases and movement in 1924. Hence, dating your watch can only be based on the format of the signature in combination with the serial numbers. The signature format is what I call the “globe signature”. It preceded the “shield” signature and succeeded the “American Watch Case Co” signature. The globe signature serial numbers range from 1000095 to 1091769, meaning about 100 thousand have been made. Looking at production volume, derived from case serial numbers during 1922-1925, this 100 thousand number most likely corresponds with 1 year. The shield signature is with almost 100% certainty introduced around spring 1922, meaning that the globe signature was introduced early 1921. This also corresponds with some advertising in newspapers that start to appear as from May 1921. Hope this helps.
