Bulova Movement Date Markings

here's the hieroglyphic mark on the movement on that tube lug bulova:

other bulova movement markings. I took this off an old Bulova service bulletin. '46 through '49 are sometimes marked "A6", "A7," etc. Then, starting in 1950s, they went to "L", such as "L0" for 1950, "L1" for 1951, etc. Note how the marks repeat every 9 years (for the most part). Guess you have to guestimate the age of the watch based on the case to know when the movement was made!

Pretty Neat !!! I guess that might put my BULOVA PHANTOM at 1926 (triangle stamp next to the detent screw). I am pretty sure that it is earlier than the mid-30s (the next use of the triangle).

Bruce,

Thanks for posting this reference table. I have seen those odd markings on my Bulova's and was told to concentrate on other things when I inquired about them. I'm presuming it was because no one had the answers.

Rather primitive - why not just print the date? Then a key or translation would not be necessary!

Bruce,

Thanks for giving us a guide for dating early Bulovas. Like many things the more we know the more we want to know. Does anyone know the scheme of the movement and case numbers these early 1920’s and 30’s Bulovas follow? The numbers are quoted and shown in all the auction listings and some sellers have given me imaginative interpretations for their relationship to age. Any guidance will be appreciated.

Regards, James

As someone who is new at collecting vintage Bulovas, this is exactly what I've been searching for. Thank you for making the post. I also have the same question as Mr. Westall.
