Hermle Mechanical Wall Clocks are excellent clocks designed to last for years, operating on spring wound power or gravity driven weights. Many of Hermle’s Mechanical Wall Clocks have Strike Movements that need to be setup properly and adjusted to ensure optimal performance. Let’s get into the details of how to setup your new Hermle Clock that has a Strike Movement.
Upon receiving your new Hermle Wall Clock, unpack the clock from the box it came in and carefully remove all of its components. It should include a pendulum, weights and the body and frame of the clock. Remove any packaging that may be protecting the bells, chimes, chains, hands and other delicate metallic pieces.
Follow our guide HERE to properly hang your new Hermle Wall Clock to a Wall so it can be properly setup with its internal components.
Remove any remaining ties or protective packaging from the weights and hang them on the tabs at the base of the chains properly.
Hang the pendulum of the clock to the pendulum leader which will either have two holes to hang on, or two short, horizontal bars to hang on.
The beat of the clock is essentially the tune of the pendulum, which allows it to continuously swing freely from side to side with equivalent periods from center to left and from center to right. When your Mechanical Hermle Clock left the factory, it was in beat, but during shipping it is possible and likely that it went slightly out of beat due to vibrations in transit. Not to worry, putting your clock back into beat is simple and can be done in a few short steps. The clock’s escapement (the component that makes a tic-tock sound) has a slip clutch component that allows for the pendulum to be adjusted and put back into beat. When the clock is vertically hanging and operating, listen for the tick-tock sound and push the pendulum leader just past the point of resistance in a direction for a moment to adjust the period of the pendulum. Listen for the tick-tock again and continue to make adjustments until you hear a tick-tock with an even period, like a metronome. If you need more information on setting the beat of your clock, you can read this article here on Setting the Beat of Your Mechanical Clock.
Your mechanical clock most likely has a strike movement that will strike the number on each hour and once each half hour. There is a lever on the back of the clock that will indicate the whether the strike movement is silenced or active. To turn the chime on, have the lever in the upward position, and to silence the chime, have the lever in the downwards position.
The time the clock indicates can be adjusted by moving the minute hand, the long hand, either clockwise or counterclockwise. Do not move the hour hand to set the time.
It's common for a clock to run slightly too fast or slightly too slow, resulting in timing adjustments needing to be made more frequently than desired. This can be corrected for by adjusting the regulating nut at the bottom of the pendulum. Turn the regulating nut at the bottom of the pendulum to the left to make the clock run slower, and turn it to the right to make the clock run faster. A single turn of the regulating nut at the bottom of the pendulum usually will adjust the clock by 1 minute per day, for reference. This concludes the setup of your Hermle Wall Clock.
