Meaning of letters after model name?

Good question...other than just a model code to differentiate between variants in the model, mainly the dial. Hopefully someone will be able to shed some light on this. Would be nice to know if there was a particular pattern Bulova followed.

Some of the President models had different hour markers e.g. Arabic, Roman, and some just had little bars as well as different face colouring.   The "B", "C", "E" and "F" models in 1940 had all of these markers and colourings.

On a slightly similar topic the numbers and letters found on a Bulova watch movement do have some meaning....some....

The 1st and/or 2nd are usual a number: 6, 7,8,9,10,13,17. These correspond to ligne size of the movement itself.

The 3rd and 4th are usually 2 letters that reference the movement model type. Many types have slight varing aspects to them where-by parts of that movement may not fit in non-similar movements. Examples of these are AA, AN, AE, BC, BM, AF, TR, AX, EB etc.

The remaining letters actually indicate the features of the movement:

Letter “C” means “center second hand”
Letter “A” means “automatic”
Letter “B” means “day and date display”
Letter “D” means “date only”

For example:
Movement number “12EBACD”
This would mean - 12 ligne size movement, “EB” family, Automatic wind, Center second hand and Date display.
