How to date a bulova watch
Locate the date code.
Genuine bulova watches manufactured between 1924 and 2009 should all have an imprinted date code marked somewhere on the watch. Once you locate and identify the date code, you should know the year during which that watch was manufactured.
Bulova watches made between 1924 and 1949 are marked with a date code symbol. These symbols are typically located on the inside movement of the watch, so you or a professional jeweler will need to open the watch to locate the code.
