Excellent. I was about to ask if you knew what the movement serial number was.

Movement serial numbers:

10AC: 575796, 575800, 575937, 576625
13AC: 727851

Working towards the big picture and understanding these watches, we  should also include the partial 13AC movement listed in the movements category without a case. Both known examples are stamped with a "T" and "shield"

13AC: 727851 (whole watch), 727763 (movement - loose)

Great all these calendar watches! Now the hunt is on to understand the meaning of this diamond (rhombus). I have seen a ladies' model too with a T and a diamond.......

I guess I should add the photo here too. This is the watch in one of the the display trays at the museum. I took this photo when we visited in October 2019

It is interesting that this watch has a 6 digit case s/n, while Stephen's (same casing) example has no s/n. The other 2 known 13AC tonneau and 10AC square both have 7 digit s/n's.

Just noticed that there is a 7 at the end of the case s/n that I did not see due to all of the watchmaker markings. Record updated.
