"Jauch Clock Movements get replaced by Hermle Units"

Every Jauch clock movement is discontinued as the company is out of business.

What this means is you would be ordering a new movement made by Hermle instead. The Hermle clock movements are of equivalent quality and size and have the same functions.

These conversion kits are only good for the three weight Jauch floor clock movements.

If your Jauch movement is anything other than this it will have to be repaired instead, please email us to set up a repair to clockworks@clockworks.com

If you do have the three weight Jauch movement then your on the correct path to get your clock running again with a brand new Hermle movement conversion kit as described below.

The only time this unit should be repaired is if the unit has no available retrofit and it's the last resort. The Jauch company went out of business so long ago that the movement has to be over 30 years old at least. If there is no conversion kit, then a repair is the only way to go and there is no other option. If the movement is repaired rather than replaced, at least there will be no need for modifications to the dial or the pendulum top hook.

The new movement is much easier to get parts for. You can upgrade the pendulum to a metal Lyre style if you choose where this is not possible for the Jauch unit. The movement can be replaced again in another 25 years as the conversion movements are still available. If anything were to ever happen to the dial, hands, gong, weights or pendulum, then you can get all this new. It costs less than a repair especially considering a repair would have to be done every 5 to 8 years. A new movement is cheaper than an overhaul, it will last longer, and is faster and easier.

  1. The Hermle conversion kit is equipped with the movement, shims, seatboard screws, hands, and pendulum hook.
  2. Attach the dial to the clock case if it is not already attached.
  3. Install moon gear on the Hermle movement if needed.
  4. Make certain the movement is in beat. On the back of the movement, the leader and crutch must move the same distance to the right of the handshaft as it does to the left. If it does not, push the leader and crutch to one side until they are equal.
  5. Install movement on the shims provided, lightly tighten the seatboard screws. Install the Hermle pendulum hook on the stick.
  6. When adjusting the hammer wires, lift the hammer, and using the thumb, index and middle fingers, form a “V” to bend the middle portion of the wire in the direction needed. Hammers should be about 1/8” from the rods while at rest and they must hit squarely on the rods. Several adjustments may be necessary for best results.
  7. Level the clock side to side and front to back solidly on the floor.
  8. Install pendulum on leader.
  9. Install weights on the clock with the heaviest weight on the right as you look at the clock.
  10. Install the hands on the clock in the following manner: Place the minute hand on the clock and turn it slowly until the movement chimes the hour. Remove the minute hand. Place the hour hand on the clock pointing to the number that indicates the number of times the clock just struck. With pliers, grasp the hub on the minute hand and turn the hub to reorient the square bushing on the minute hand. Repeat until the minute hand slides onto the movement arbor at the 12 o’clock position.
  11. Lowering the pendulum by one turn of the rating nut to the left will slow the clock by about one minute per day.

You will have to have it done all over again in 5 to 10 years. No repair is as good as a new unit. Sometimes these units cannot be repaired because of lack of part availability. If something were to ever happen to the dial or hands then there is no replacement if staying with the Jauch movement rather than the Hermle conversion kit.

Some modifications may be required, such as listed on this page. Sometimes the pendulum will have to be shortened 1 1/2 inches off the wood stick. The dial would have to be attached to the wood case if it isn't already.

"Overall it is our opinion that a replacement makes more sense than a repair"
The following modifications are usually required:
  • The dial must be attached to the case rather than the movement. There is a 50/50 chance really, sometimes the dial is attached to the case and sometimes it is attached to the movement with dial feet. If it's attached to the movement then you will need to unscrew or chop off the dial feet and attach it to the wood case instead.
  • The replacement for the Jauch clock movement would have to be shimmed higher (Included)
  • New lead weight would be installed into the existing right hand chime weight shell. (Included)
  • The top hook on the pendulum will have to get swapped (Included)
  • The pendulum may or may not have to get shortened. If the clock is too slow, even with the bob all the way up, the pendulum stick must get cut 1 1/2 inches shorter.
  • If you need assistance on replacing the Jauch clock movement you can call 800-381-7458
  • If this does not work out for you and you have the original packaging so it can be resold as new, you can return this kit for a refund.
