That would be the Banker
Agree- Banker
Not a Banker gents. Possibly another La Fayette with non matching hands. I also think the 'Governor' might be a close match.

Here's the Banker I ID'd from - it's shown in 1927 and 1928, this is a 1927 advert

The La Fayette is not shown with a partially obscured six the way the Banker is. I'm more of second guessing the La Fayette we recently ID'd. I agree that the hands are not correct for either.
Lugs differ on the 'BANKER'

is there an ad showing the 'GOVERNOR'?
Banker is a totally different case. It didn't change design right throughout the 1920s. As Fifth shows the lugs sit on top and aren't continous like the La Fayette and Governor.
This from the price guide. Dial is the same but states 17J.

The hands looks like new, being replaced for sure, but I have a question regarding the figures on dial. There was no luminous dials in that period, only with black paint figures, or somebody repainted those figures later?

Constantin - the dial was most likely repainted somewhere along the timeline. It was originally lumed. I'm not sure if what I see is the lume TURNED black, it might be paint. Replacement hands are available.
Yeah I think the Banker is a fatter watch IMO.... I'm thinking Lafyette.
Hey, I'm not that fat........ oh, the watch, yeah, maybe it is plains but the LaFayette doesn't have the partially obscured six like this watch does. At this point I agree it's not the banker, I'm just not sure what it is.
