by marking the case (ser. nr, globe), the movement (no caliber, no ser.nr.) and the dial (no sign) I suppose that watches were produced in years 1918 or 1919
I guess pocket style Lady Maxim , as att advert
I would say she's a Lady Maxim too. Nice watch Jaroslav.
Would say 1920 Lady Maxim. What year was the advert from again?

Why 1920?
Wow Love that movement. Nice Advance/Retard. Is there some markings on plate (below)? 
Gonna go w/ 1919. Maybe 1920. When do we first see the globe appear again? I want it to be 1918, but..... Wow the year is tough for me on this one.
1919 Lady Maxim

Will marking on plate is something like "A.HABLE" or "A.HASLE" it's almost unreadable
- Case signed "American Standard" with globe symbol
- Movement signed "Bulova"
- Dial unsigned
- No movement caliber designation
- No movement serial number
- No movement date code
- Case serial number begins with "10"
- Case style of pocket watch, Typically converted to wear on the wrist; crown at 12 o'clock position
this corresponds in every detail, dating marking before or after this year in some detail different
Advert dated November 19 1921.
FLAG !!!
By case s/n this one should be a 1920.
