Movements & Kits (Mechanical) Hermle

Hermle recommend that replacing a Hermle clock movement is often quicker and more cost effective than servicing or repairing an old one. Using a new movement ensures you take full advantage of the advances in manufacturing technology. They state that their movements are ready to fit, however some lubrication may be required. Hermle guarantee new movements against mechanical malfunction for a period of two years.

Movement Required:
If you require a complete movement which is not listed below you can request a quote via our Hermle movement parts search category by searching and selecting "movement" in the Hermle PDF Diagram Number look up and then add it as a non listed item, you will need to provide the pendulum length you require in the description field.

Pendulum Length:
The Hermle pendulum length is stamped on the back of the movement, next to or underneath the calibre. The "cm" length is measured from the suspension pinning point to bottom of the pendulum tip.

Hermle state that movements with pendulum lengths 85cm or greater are no longer supplied with a low anchor bridge due to the weight of the pendulum

Deadbeat v Automatic Beat:
Automatic beat escapement movements are for narrow waste (pinch waste) grandfather/grandmother clock cases. With automatic beat the case has to be wide enough for the customer to over swing the pendulum when starting the clock. If the clock has a narrow waste it can happen that the dead beat is the only option because the dead beat does not require room for over swing.

Hermle state that movements with pendulum lengths 75cm or greater are no longer supplied with a dead beat due to the size of the pendulum.
