Antique Seth Thomas Cottage Clock With Alarm And Chime

Antique Seth Thomas Cottage Clock With Alarm And Chime. Runs super and chimes on time. But im unfamiliar with the alarm part of the clock. It does wind up but ive not figured out how to set it on the center dial. So unknown on alarm. But caae is in great preowned consition and movement as ypu can see in photos great shape.
