First BBI Movement I have recorded seeing.

I also have recorded a number 1923 AAI's so I'm not susre if that helps date the movement or not.

A very nice early ladies watch all the same.

My questions w/ this one are:

date of movement? case SN for dating? Only BBI in database and I can't find this caliber elsewhere on the web.

1922 ad seems to match subject watch but blurry and model number not listed (general ad more than specific). 

1923 ad Fifth points out subject watch exploding dial vs 6714 ad dial, and the same 1923 ad w/ another model number showing diff case/ w exploding subject dial (the ad for the 5714 shows exploding dial)? Not sure that helps me much.

1924 ad (below) seems to match subject watch sans exploding dial and what could be model number 67?4

All seven ads from 1922-24 appear to be from Sat Evening Post.  Early in Bulova history, so I assume consistency in model numbers btwn ads in this three year period in same magazine.

IMO two stars, based on all this.  It wouldn't take much (a legible ad) to get three stars out of me.  And that would be for year 1921 model 6714.  The case SN trend is very strong to overlook.

Any differnt ideas or opinions from anybody else?

Check out all the last digit of model numbers in ad linked above.  We are seeing "even" last digits for model numbers which are all solid gold. The exception are the green gold filled (150) and the platinum, but its platinum.
Just looking for patterns in model numbers and what they may coorelate to in watch charactoristics.

Similar last digit of model numbers patterns in this ad, again platinum (and silver 39153) are exceptions, but the solids end in even numbers, and the fills end in odd numbers (e.g. 153, 6713, 155).

The "pattern" breaks down in this ad, so it may not be a pattern, unless its only for certain model series...  

And in this 1927 ad, we see its kinda hit and miss for even last model numbers, again w/ exceptions being those in or with platinum, diamonds, among a couple others.  Even w/ exceptions, lots (most) of solid gold numbered models end in an even number.

We have several Lady Maxim ads from 1922 showing this exact case/dial too, backs up the theory that the numbered Bulovas were this model.

Yep Bobbee, I agree with that.  This may apply to several watches we have around this time.

You mention :If My theory is correct the Case seriel number Dates the Watch to 1921. You have an article about this theory or can you explain?
