Information about Bulova Watches

BULOVA INFO
Bulova Date Codes
In the late 40’s Bulova began using a series of codes to denote the manufacture date.
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- 1948 and 1949 respectively. These must have been the first years that Bulova implemented it’s new dating system. Who knows why they jumped from A to L…?
O was skipped - they used P for 1980’s. QRS were skipped and T was used for 1990’s. Who knows why…WEIRD!

Bulova Caliber Numbers
Well, here it is straight from the horses mouth. This is the reply I got from Bulova:

“It’s been probably close to 30 years since this numbering system for watch
movements has been used by Bulova.
This is what I know:

a.The number digit signifies the Ligne size of the movement.
b. The next two alpha digits (as below “AE”, “AA”, “CS”) have no real
meaning other than a reference ( like a name).
c. The third and fourth, and sometimes fifth alpha digit would signify the
functional characteristics of the movement.
I do not have any printed references for this anymore, but I seem to
remember the following:
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 “10BSACB”
This would mean -
10 ligne size movement
“BS” family
Center second hand
Automatic wind
DayDate display.

Of course, if as in your examples below, there are only two letters, then
the watch does not have the characteristics mentioned above.

I hope this is of some help, because we no longer have any remaining
archives which could explain more in depth.”

I hope this is what you are looking for. That is what I like about the NAWCC, we all like to help each other.
