I’d like to get the panels thoughts regarding the identification of this one. There have been some lively discussions related to the early Senator vs the Executive. On this one, the case number begins with a 5, and at first I thought this was an Executive, but the placement of the sub second dial, which is square, is consistent with a Senator, not the Executive. It closely matches the Senator, but the Senator doesn’t show up in ads with a square sub seconds dial until 1926. Prior to that the ads show a circular sub seconds dial.
Also, while I don’t have a caliper for a precise measurement, but its square and in the 26 mm range, not the 24.8 mm that Lisa indicated was the size of her Executive in one of the previous discussions related to the 1926 Senator.
This one has a 10AP movement which was made in 1925 and 1926, and I don’t see a date code. Also, the engraving pattern on the back matches the back of this Senator

To further confuse things, it also has a closed 9. Could it be a transitional Senator, while they were otherwise still making Senators with circular sub seconds?
Date stamp should be up near the winding stem. Circle or triangle.
The combination of the components certainly don't match any of the advertisments for the Senator, but one common factor for the Bulova Senator's is the lugs that appear to be seperate and not a straight line as with the Executive.
I'm half inclined to say Unknown, but for now based on the other two Senator models we have in the database I'll go with a 1925 Tentative Senator.

Great watch David, I bid a lot of watches, seems like I recently bid on this one. It's a '25 I think, pretty sure there's a circle date stamp near the crown. This is another of the early movements with a period in the serial number. I wonder what that is supposed to signify.
We do have this one ID'd a couple times as Senator but I'm not sure I agree. The engraving on the Senators in the adverts we have is quite different.
This advert is December 1926:

This advert is December 1925 and show a completely different watch:

I'm going with the flow as a Senator ID but I will be tentative as well. Either way, this is a wonderful, early Bulova wrist watch in fabulous condition!
