Notes on the Hermle 140 / 141 Series
The Hermle 141 and 140 series are all spring driven with 85 x 98mm plate size. They all take a #8 size clock key.
What is being offered on this page is the movement only with out the pendulum, gong or dial. These movement come as the movement itself with its hand nut and if a pendulum unit, comes with the suspension spring and leader.
Removing the 140 / 141 Calendar
Many of these units come with a calendar as indicated by the letter K after the movement numbers.Read More »
This is the usual way the movements are supplied by the manufacturer. This way it covers movements with and without a calendar. When replacing a movement that does not have a calendar feature, sometimes the new movement only comes into the country with a calendar attached and will have to be removed. The below information will enable you to remove the calendar portion if the calendar tube is in the way of installing the new movement to the dial.
If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.
Now you will see a small C clip that blocks the hour hand tube from coming off. Remove this C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Please note the exact position of the new movement’s hour tube before taking it off and put the old unit’s hour tube in the exact position.
What I mean by position is the humps on the snail looking portion that is attached to the hour hand tube has to be the same position. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock. Then put the C clip back into place to lock in the hour hand tube.
One last thing. The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. Keep in mind you’re not damaging the movement by doing this as this is what is meant to be done.
It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock correct, and it strikes these hours out with the correct number of strikes, then the rest is ok also.
If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.
The 040 and 070 Compatability
The difference between the 040 and the 070 Hermle units. The 040 series has a one hammer back for a gong strike, the 070 units have two bells on the back.Read More »
It is common to get a 070 as a replacement for a 040 gong strike ordered, this is because the two units are cross compatible. You only need to remove one of the hammers with its wire, and take off the bells on the back of the unit to make it a gong strike instead of bell. The reason this happens is because to put in a large purchase from Germany requires a min purchase requirement for each movement series. It only makes sense to import one movement series that is cross compatible than two series. In most cases the customer leaves the bells and ditches the gong as the sound is better.

Selecting the movement
The numbers on the back plate of the movement is everything one needs to get a replacement.
