Runs about 4 minutes fast per day, needs cleaning and a new crystal. Unable to find "Excellency" model name or "6BC" movement in data base, but not confident enough in my knowledge to make changes. "LO" on case indicates 1950, but "A9" on movement indicates 1949.
Excellency is your best clue! It's going to be a "Her Excellency"
There are lots of "Her Excellency" variants, so, now that you know what you're looking for, take a look at the vintage ads in the general 1949 timeframe (look at least a few years before and a few years after) and see if you can find your exact model. If you find it, post the ad in this thread.
49 (A9) is the year the movement was made. L0 = 1950. That is the year your watch was made. I would change the model year to 1950.
I agree with Bob. 1950 is the correct date. Good catch, Bob.
Thank you all. I've changed the model year, but can't find a match in the ads yet.
Looks like this 49 Excellency BB to me. Does anyone concur? Last ad on the right.
I agree. The case details and the round crystal match. The only difference I can see is that my watch has gold numerals, while the ad seems to show black numbers. However this might only be due to the quality of the printing of the ad. Any other opinions?
In reply to I agree. The case details by wgcinder
Wg, I think the number difference is just a slight change for model years 49 to 50.
Sure looks like a match to me. Another good job, Bob.
I wouldn't worry about the black numbers versus gold ones. We often see dial variations--many times much more drastic than just changing the color of the numbering. Bulova often started out with one type of numbering, like luminous or black, then changed to gold. Others on the site have more expertise than I do, but I think that most of them will agree with this assessment.
Good eye Bob!
These ladies watches are tough to match because of size, and as Lisa said, dial could be a variant or done that way for ad purposes.
