Here’s a Westclox “Dunbar” electric wall clock I repaired. The dial is paper on a metal plate, covered by a glass lens, and the case is white plastic with a metal back. This clock uses the Westclox designed M2 self-starting synchronous motor. The red dot on the dial is the power outage indicator. The indicator starts out red. Then, plug in the clock and set the hands. Push up on the post in front of the hand set knob to turn the indicator white. Then, if there is a power outage (or a glitch long enough for the motor to slow down), the indicator will turn red, telling you that the time on the clock may be incorrect and needs to be checked.
The date code on the movement is 4 41 (April 1941),
Repair job 6502. I disassembled the movement and cleaned it, polished the pivots, installed 5 bushings and a new cord. See more photos (there are 79 photos showing the parts of the clock).
