Your well preserved Westclox alarm clock appears to be from the late 1920s or early 1930s.
Radium dial I suppose? Apparently, the Western Clock Co. (Westclox) had a factory in LaSalle, Illinois, and one in Peru, Illinois. Attached is a picture of the factory in LaSalle, Illinois. My first watch was a Westclox Pocket Dax. In grade 1, a loooong time ago, I took it to pieces in class. The teacher took it away from me! My second watch was a Westclox wrist watch.
