Wind up the clock and the chimes so that the springs in the clock are tightened and ready to work. The hole on the right side of the face is for the clock spring, and the hole on the left side is for the chimes. They both wind inward toward each other. Do not overtighten.
Start the pendulum swinging, either by slightly tilting the clock to one side briefly or by manually giving it a push.
Slowly push the minute hand forward, moving clockwise until you reach the 12 position. Pause and count the chimes.
Move the hour hand gently clockwise to the position indicated by the chimes. For example, you would place the hour hand at 5 if there were five chimes.
Swing the minute hand of the Seth Thomas clock slowly around the face just past the 12. Wait for the chimes to ring and continue moving the minute hand clockwise until you get to the present hour.
Set the minute hand to the current minute, moving only clockwise. If you go past the current time, stop the pendulum and wait. Restart the pendulum at the current time.
