Movement Serial No.:
Case Serial No.:
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?
