Hermle Clock Movement 241

Notes on the Hermle 241 seriesHermle movement identificationThe obsolete 241-070 and 241-040What Happened to the old movement?Other Names Used

The Hermle 241 series movements come in both chain driven or cable driven styles. They are all pendulum units with a 85 x 98mm plate size. What is being sold on this webpage is the movement with the chains, hand nut, leader and suspension spring. These units do not include the weights, pendulum, dial, hands or chime block.

How to identify a Hermle movement

On the back plate of the clock movement you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if the clock is weight driven or spring driven, if it has a pendulum, the size of the movement and the length of the hand shaft and much more. To match up the numbers to the new movement numbers is to get the exact same movement you have now but brand new. Since the new movement will be the exact same and not some knock off imitation, all of your existing clock components will usually fit just the same as the old unit.

The popular 241-070 and 241-040 is no longer available. The closest equivalent to that movement would be the Hermle 241-080 94cm.

The only difference with this unit compared to your old unit, is it will come with a bell on the top instead of having a coil gong on the back of your movement. So you would remove the coil gong from your clock case because you will no longer need it.

This new 241-080 Hermle clock movement will come with chains, leader, and suspension spring. The new unit also comes with a bell on top, so now you will have a bell strike clock instead of a gong strike clock. Your weights and pendulum and clock hands should be all the same as it was and these parts will work on your clock.

With age, the mechanical clock movements oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost hundreds, if not over, a thousand dollars and in some cases it can take weeks or months to complete it.
