The hand is touching the hour hand. pull it a little. it will stop touching the hands. and when fast there is a bob(nut) below the pendulum. one full turn(right) makes it slow 2-3 minutes every 24 hrs. one full turn to the left makes it speed up 2-3 mins every 24 hrs. turn it. record the time. wait for 24 hrs then check the time against your watch or any clock. if a few minutes late or advance, keep turning the bob and wait 24 hrs everyday till its showing right time.
