Now it gets interesting, I originally bought this watch as "Norma" in 1924 (judging by the dial style)
but when I opened the watch I came to the conclusion that it would be rather model "6718" from 1922.
Movement is labeled as Bulova WCO RP1, case marking has 18 MPK and engraved date 12-11-22
it's alchemy, maybe someone will know more

Fifth,
it looks like it really is PP1, BP1 it will not

We have three votes for "6178" - Panel Members, sound off?
...or the Lady Maxim?
1922 ad. Same watch as in the S.E.P. ad, same description.
Bottom left watch, "18 Kt. white gold, 17 jewels".

Yes, I am on board with the idea that these were indeed Lady Maxim branded Watches, look closely at the left side of the band, lower edge.
Dial has a pattern I have not seen before, possibly re-dialed?
Jabs, I'm betting the movment is PPI , not PP1. We have linked movement in movement database, but its not listed in the main watch database. I think the linked mvnt example is one for which Alex has movement but no case or complete watch.
I believe this case shape is “corner cut.” Am I wrong?

This is a Octagonal case according to the Art Deco Bulova book.
