This is apparently a Ladies pocked watch that was converted to be worn as a wrist watch. No date symbols on the movement and the only serial number is on the case. Currently runs and stops so needs a good cleaning.
Case is 25.78mm dia. 8.16mm thick
Crystal is 19.71mm
With the 20 year warranty on the case I am assuming that it is 10k gold filled

...and another similar 1922 ad
and Bobbee found a 1922 ad for the 150 (not "B" variant, and not on the strap above) w/ Lady Maxim on the dial.
In reply to Looking at this one again, I by bobbee
You said that about a year ago....maybe just not for this particular watch. You said something like:
Lady Maxim is model (series) name, and the model numbers are similar to variants we use in later watches.
So subject watch would be Lady Maxim variant/model number 150-B.
I think they advertised them both ways- as numbers and/or (series) names.
What do folks think about "Lady Maxim 150-B" for subject watch ID?
