Bulova Watch co. on the movement puts the 9A at post-April 1923. Can't make out the date mark to the left of the stem detent screw.
The case appears to be a little earlier.
LM 150-B with new(?) movement.

here I made a detailed photo data mark is circle, ie 1925
Cool watch jabs, I like these old beauties. From this era, I usually go with the Lady Maxim ID too.
I'm in agreement w/ stuff said, and am gonna look for a 150-B ad or watch example :)
Here's a comment field by Bobbee from second page of record linked above:
An ID at last guys.
The 150-B, 1922 ad.
Will, are you proposing that this is a 150-B? I'm (as usual) confused.
In reply to Will, are you proposing that by Geoff Baker
Sorry....I wasn't clear...I was not suggesting 150-B, but just posting the ad Bobbee had mentioned in previos comment block. I think Bob was suggesting 150-B and I wanted the ad visible.
Would agree if the movement is original then 1923 more likely the date.
I'm so looking forward to cracking the mystery of dating these early pre 1924 watches.
Unknown for me.
Date on movement 1925, I would put that down to a new movement change in that year, or a more recent sympathetic replacement by a collector/repairman.
I would put the case as 1921-ish, due to the case markings.
1921 LM 150 "B", or just 150"B".
My reasoning behind the Lady Maxim ID is the recent ad found with Lady Maxim on the dial and a Bulova ID number. This, combined with the reasoning that why would Bulova be advertising the identical models under two different identities at the same time, as seen in the ads, has been a popular theory of several members.
I agree with Lady Maxim, and my new favourite expression is 'sympathetic replacement'.
