Bulova mark there dates using a date code system. This can be found on the back of the case and on the movement. No need to worry about long serial numbers on these! The code consists of one letter and one number, eg. They used the letter M to signify the decade 1960 to the end of 1969, and the letter N to indicate 1970 to the end of 1979. 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. Step 2 - Gather information about your watch. Write down all the details inscribed on the back of your watch. Take a few close up and clear photos of your watch, including the: front of the watch; back of the watch; inside movement (if you can open the watch) inside back case (if you can open the watch) additional photos.

The code consists of one letter and one number, eg. M7. They used the letter M to signify the decade 1960 to the end of 1969, and the letter N to indicate 1970 to the end of 1979. The digit represents the actual year in that decade. Therefore, M7 is interpreted as 1967.

L=1950s, M=1960s, N=1970s example: L3=1953, M4=1964, N5=1975, etc.

It is possible that you may have a watch in which the date code on the movement is different to the date code on the case. That is common, however, it has been known to never seen an original watch that had a variation of more than one year. If you see one that has three or more years difference in the date codes, I suggest that the watch has been re-cased or made from 2 separate watches. This probably doesn't really matter unless you are a serious collector and are only interested in completely original items.

The dates codes started in 1948 with'A8' and carried on in sequence with a few exceptions , they missed O out I suppose because of the confusion with zero and then missed 'Q,R and S' out for what reason I don't know maybe someone at bulova just didn't like those letters , after 1999 to my knowledge they reverted back to the 'A' series numbers again I'm not a 100% percent sure but I had a very modern quartz bulova which clearly beared a date code of 'A0' so that's what I'm baseing it on
