As usual, Rich has it right. I will add that the clock is a mechanical clock, not electric, with an electric winder. There is the solenoid that Rich mentions which pulls the arm to the top. Then the arm ticky-tocks down to the bottom, where it closes a contact. This activates the solenoid which sucks it up to the top again where it starts all over. Sorta like winding your watch every 2 minutes or so. Advancing the time 24 hours speeds it up a little, setting it back 24 hours slows it down a little. So, once it's working OK, watch the time for several days and see if it gains or loses and adjust accordingly, a little at a time until it's right.

I used a 6-volt lantern battery to power the unit while working on it at my desk. The clock speed is adjusted by every action of the knob to move the hands. Moving the hands forward speeds up the mechanism and vice-versa. There is a small fuse in the line from the power supply in the dash. A separate wire connects to the light bulbs and is dimmed with the rest of the dash lights. Again, numerous shops will do this work for you as advertised in HMN. A watch repair or grandfather clock repair shop can clean and tune up the clock part if the automatic winder is working OK.
