Luminous dial. These are often called “Dura Case” clocks because the Dura Company of Toledo, Ohio made the cases. These clocks have a nickel-plated die-cast case with a pewter like finish that Westclox called the “Butler” finish. They have a Baby Ben movement.
A quartz reproduction of this model was introduced ca. 2008. It is called the “Athens” and can be identified from the front by having an alarm setting disc which rotates behind the dial. Also it says “Big Ben” on the dial and has a quartz movement.
