SERIAL NUMBERS TO MANUFACTURE DATE REFERENCE GUIDE
Many of you are curious how to tell the manufacturing date of your watch from the watch serial number located on the movement, or sometimes case. For ease of reference, we have compiled all the serial number references we could find in one convenient place, and will add additional serial number tables as we can. This serial numbers are compiled alphabetically by the watch brand.

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 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.

In the 1930s, Elgin began using a single-letter prefix to replace the "millions" digits on their serial numbers. So if your Elgin watch has a serial number starting with a letter, you must determine the millions digits from the table below in order to determine the full serial number.
| Letter | Millions Digits |
