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 serial
numbers!
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 two 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. |
