How do I replace a broken clock movement?

The quartz movement in my wall clock no longer works. I'd like to install a new movement in the original clock body because it was a wedding gift more than two decades ago. How do I replace the movement?
—Greg Lawrence, Appleton, Wis.

You'll need a few key measurements, Greg, before ordering a new clock movement. Begin by removing the hands from the clock face and the clock movement from the body. Measure the following:

*the length of the minute hand, from the center of the mounting hole to the tip [Photo A];
*the thickness of the clock face combined with any backer board and spacers [Photo B];​
*the length of the movement's center shaft from the case to the end [Photo C];
*and, if your clock has a pendulum, the diameter of the bob [Photo D].

Armed with these dimensions, call a retailer, such as Klockit (800-556-2548), and a representative will help you select a movement that fits your clock. Or, you can visit the company's website (klockit.com) and match a movement to your specifications.

If your clock has a musical chime [Photo E], the replacement movement will come with either a built-in speaker or one that attaches to the clock body. You might also be able to connect the movement to your existing speaker.
