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.
Lay the clock face down on a soft and clean towel.
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.
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.
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.
Set the correct time by turning the hand set knob.
Set the backing onto the rear of the clock and turn the four tabs into place to hold the backing on.
