Love the butler silver type dial. Double hinged case and what appears to be original ochre colored radium numbers and hands unless they were done more recently.
Now the name is a toss-up it seems between two names for what appears to be the same model during the same year.
After a bit of chat with the gents I'll agree it does look abit more like the Senator... but really.. could be the other as well.

Well, your dial matches the Senator ad.
The other late 20's Senators in the db also match the ad and have the 10AN like yours. The only other Executive in the db matches the Executive ad and has a 9A movement.
So I would vote Senator.
Well case on both look the same Dials look to be differnt a toss up here, Dial would look great redone.

If it were mine I wouldn't touch that dial.
Looking at the hands it looks more like the senator to me.
nice watch both ads above show open 9 dial.

I noticed the same thing. Closed 9 on this guy.
Hey Jerin, The dial says Senator, look at the sub seconds dial. That's a dead match to the Senator ad.
The lugs on the executive are more elongated than the senator. I belive yours is the shorter lug senator. IMO
