How to Repair Hermle Quartz Movement
The "movement" of a clock is a term used to describe the internal mechanisms that contain the clock gears. The Franz Hermle Clock Company of Gosheim-Wuerttemberg, Germany, has manufactured ornate, hand-made clocks, like the Qaurtz, since it was founded in 1922. When the gears inside the Hermle Quartz begin to wear out, the most efficient and cost-effective way to fix the movement is to replace it with a new one. Replacing the movement on a Hermle Quartz takes approximately one hour.
Step 1
Lay the clock face down on a soft and clean towel.
Step 2
Access the inside of the clock by turning the small tabs that hold the clock backing in place to the left. There is a tab in each of the four corners. Lift the backing from the rear of the clock and set it aside.
Step 3
Remove the four small bolts holding the clock's movement in place. There is a bolt in each of the movement's four corners. Remove the bolts with the small open-end wrench.
Step 4
Lift the old movement up and out of the clock casing. Set the replacement movement in and attach the four retaining bolts. Tighten the small bolts with the wrench.
Step 5
Set the correct time by turning the hand set knob.
Step 6
Set the backing onto the rear of the clock and turn the four tabs into place to hold the backing on.
