IBM Master Clock Questions "Click" to Login or Register 
Ken Snowden
posted
I bought this clock at an auction because I like the art deco look. I do not know anything about this electric driven movement. The only writing that I can see on it is Pat. 1,878,931. Can someone help me with a schematic or maybe some idea of how to check the power to drive this movement?
I found this is an IBM Model 25 Master Clock
