I’m not sure exactly who made this store regulator calendar clock (possibly Waterbury). I write often that I don’t have many American clocks in my collection, but as I document them, I find I have far more than I realized!
I have two calendar clocks in my collection and I am hoping to add a double dial clock to my collection eventually. This clock is in fair condition. It was the first calendar movement I worked on. It is a simple modification driven from the hour tube.
Many of these clocks have permanent advertisements on the glass, this one has clips around the inside of the glass door indicating that this model used replaceable paper advertisements posted on the inside of the glass….I wish I had some of those old posters.
