Case has no markings on the back - Gold filled Symbol on movement looks like a rhombus with 10 marked in it??? I have put 1922 only so I can get this on the site for your consideration. I do not know the date. Stem and crown appears to be a replacement??
Edit: Avertisment Added: The advertisment is from 1922 add no 3 of 36 - Top "954", but this watch is 14kt white gold and the one I have is yellow gold- to me the case looks the same and the face looks the same. Case is 24mm. Lug end to lug end is 27mm Hinged Case opens from the side
Edit: Changed date to 22 from 24
So does Lady Maxim 953 describes this watch best? (based on ads and other documentation).
We have other Lady Maxim ID's, some with Lady Maxim on the dial, some with Bulova on the dial, and some with no dial signature.
Do we have an ad or other watch ID'ed as Lady Maxim with subject watch case shape? I'm not seeing one, but that may not matter, unless this case shape was not part of the "Lady Maxim" group.
Begs the question...is Lady Maxim the "series", and the numbers (e.g. 953/954) the model names (numbers)? Or would Lady maxim be the model, and the numbers are variants? LOL
Kind of a mess, but an interesting mess.
I posted several LM ads that aren't in the 1920-29 ads in the "Evidence" thread I posted regarding LM/early numbered watch ads here:
http://www.mybulova.com/forums/evidence-early-numbered-bulovas-were-ladyhudson-maxim-wwatch-line
There is this ad from March 1922.
Lady Maxim=model, number=model variant number.
All the evidence points to it in the above linked thread.
