There are no number tables that I am aware of to cross reference the date of manufacture with the serial number.The serical numbers were simply for identification purposes only.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.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.
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.

This can be found on the back of the case and on the movement.
No need to worry about long serial numbers on these!
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.
