In case some of you have not seen this list from IBM. https://www.ibm.com/ibm/history/documents/pdf/clocks.pdf
This list is likely the model types that the Time Division was responsible for and probably ended in 1958 with the sale of the time division.

Most interesting is the odd items IBM made and sold by this division that were not clocks. Like the Model 25 Dayton bread slicer, and the model 1-11 ITR casement window catch for burglar alarms. Not to mention the model 20 Dayton computing cheese cutter. They are however a lot of clocks listed too. Joe
