Regulate Your Clock for Fast & Slow

To regulate your clock, hold the pendulum disc and turn the rating nut located under the disk to the left to make the clock run slower and to the right to make the clock run faster. One turn of the nut will regulate time keeping approximately two minutes a day. Be sure the pendulum disc moves downward when the rating nut is turned to the left; it may be necessary to gently push the disc downward on the pendulum rod.

It is better to adjust the rating nut in small increments at a time and slowly approach correct time keeping as opposed to turning the nut too far in either direction on the initial adjustment.

"Murray was extremely thorough and helpful with a clock my grandfather bought in 1939 and I inherited. I was in for a consult on the cleaning and refurbishment of the clock. He knows clicks!"

"I brought a grandfather clock in for repair today. Murray was able to evaluate the clock and repair it while showing me what he was doing and he answered all of my questions. The clock is now home and running perfectly. I highly recommend National Clock Repair."
