BULOVA

Bulova date codes: 1924 - 1949

Between 1924 and 1949 Bulova used a date code symbol on their watch movements to indicate the year that movement was assembled.  Between the same years most Bulova watch cases also had a serial number that started with the number corresponding to the year of assembly. 

The following table will help you date your vintage Bulova watch movement. 

Bulova Movement Date Codes 1924 - 1949

Bulova date codes: 1950 onwards

Watches dated post 1949 have a 2 alpha-numeric date code on the outside back case, whilst watches dated before 1950 usually contain a date code symbol on the inside movement.

The following table will help you date your vintage Bulova watch movement and case.
