Added a Certina serial number and reference number decoder, thanks to Karl for suggesting this. Added some more modern serial number formats for HP calculators, Casio watches and more. This site was originally developed for vintage items but it has grown beyond that and clearly there is a need to check dates of more modern items.

Dating your Accutron is really quite a simple procedure.
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. 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
