Interestingly, the code system is well documented from L and on...however, I have recently come across some 1940's watches with the code "A8" and "A9".These watches were also engraved with the owners name and the date- 19 respectively.In 1875, Joseph Bulova, a Bohemian immigrant, started the J.Bulova Company in a store on Maiden Lane in Lower Manhattan.Begun as a wholesale jeweler, the company produced small table clocks and good-quality pocket watches, By 1912, driven by the increased demand for wristwatches, Bulova built a factory in Bienne, Switzerland that was capable of mass-producing fully-jeweled wristwatch movements in large numbers.For the most part, these movements were cased and timed in the USA before shipment to retailers.Serial number records are available for many of the old pocket watch companies like AM Waltham, Elgin, South Bend etc. The number you need is the serial number stamped on the MOVEMENT (i.e the inner workings).Write this number down and compare it to the charts on this website.
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.
The digit represents the actual year in that decade. 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.
Should you require a more conclusive valuation of your time piece then please do not hesitate to To determine the approximate age of your watch, the serial number should be located either on the case back or on the inside of the watch stamped oto the movement Simply match up the number on the watch to the nearest number on this page to determine the APPROXIMATE age.
However, these numbers are for identification purposes only.
