Notes on the Hermle 130 / 131 series
The below 131 and 130 series Hermle clock movements have a 90mm plate diameter and is spring driven.
All clock movements in this series take a number 4 size single end key. What is being offered on this page is the movement alone with no other components such as pendulums and gongs. The movements come with the hand nut and also the suspension spring and leader if it is a pendulum unit.
131 Series Pendulum CM Notes
The pendulum length (**cm) will be from the suspension post all the way down to the bottom of the pendulum nut threads. Read More »
So this pendulum length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring the leader hangs on, all in one measurement. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length will be even though it will be marked a certain CM length on the back of the movement.
If the CM length on the old unit matches the CM length on the new unit, this is all that is needed. Sometimes it is required to use the old leader from the old unit and put it on the new unit. Now if the old unit and the new unit have matching CM numbers and there is still a timing issue, it’s usually because it had the wrong pendulum to begin with. The next question would be, did the clock ever keep time with the pendulum it had?
132-071 Timing Note
The 132-071 is a platform escapement, what this means is it has a balance wheel rather than a pendulum. Read More »
There is an arm sticking out of it and it is able to move up or down to adjust the timing. When the factory set the time, they had it keep perfect time when the arm was in the middle of this platform. This is intended to stick straight out in the middle, in between the + and - symbols. It would not surprising if this moved some in shipping and have to adjust the timing a little. It may be best to adjust this arm and start in the dead center. If the clock is slow, move the arm slightly to the + and do the opposite if it is running fast.

132-071 Product Description
The 132-071 is now improved with a Swiss platform escapement. The quality of this escapement is much improved from the past and easier to time.Read More »
We also offer the movement with the dial and the hands, to use this unit on the Schatz Royal Mariner movement that is no longer in production. The Schatz unit is not available and this unit is very close, however the winding arbors are in different places, so this is why the new dial. The hands will need to be changed also for this conversion.
- Less cost than a cleaning in most cases
- Should last 25-30 years, a repair would not
- Easy to install, we can help if needed
- Ships same day as order
Selecting the movement
The numbers on the back plate of the movement is everything one needs to get a replacement. If the numbers match then the movement matches.
If the clock is a pendulum unit, be sure to select the proper CM length that matches the old unit.

132-071 Installation Instructions
The following instructions are to install a new 132-071 clock movement. Read More »
1. Remove the hands. To remove the minute hand, hold it still while using needle nose pliers on its nut just to loosen it. Turning the nut to the left a little bit will loosen it so you can just take the nut off with your fingers. When the minute hand nut is off, you can remove the minute hand. This is only on by the minute hand mounting square hole on the movement’s square shaft. When the nut is removed it will come off if you wiggle the hand around. Now for the hour hand, this is on only by a friction fit, it has a round hole in the hour hand and presses on to a round shaft. This comes off by twisting back and forth and pulling toward you at the same time. Although you may not be able to tell, the hour hand tube is tapered wider as it goes into the movement. This means the more the hour hand is pressed down onto this post, the tighter it will be and harder to come off.
2. Take the mounting screws out. This will require a small flat head screwdriver, there are usually four screws at the 12 - 3 - 6 and 9 o’clock positions to remove. Sometimes there are also screws on the back of the clock case as well to remove so the entire movement with the dial comes out the front. So there is a couple of different ways that this may be mounted into its metal clock case but it will be either both or one of these mounting methods.
3. Taking off the clock dial. The dial is usually attached to a metal plate, this metal plate has usually three or four posts that go into the clock movement. The dial comes off of the metal plate with three or four small flat screws. The metal plate that the dial is attached to comes off by releasing the posts that go into the movement. The posts that go into the movement will come off by one of these two ways, the post may have a tapered pin, this means a pin that is fat on one side and skinny on the other. The skinny side will be stuck into a hole drilled into the post. To take this out you only need to yank out the pin by grabbing the fat end with some needle nose pliers and yank on it. Other times there will be a locking collar with a set screw to loosen and the collar comes off. With the posts released from the movement, the dial will come straight forward and off of the movement.
4. Installing the new movement. Installation is the reverse of the removal. There is nothing usually added to the installation. Put the metal plate with the posts back on the clock movement with its tapered pins or set screws. Install the movement with its metal dial plate into the round metal clock case and reattach. Install the clock dial back on to its metal holding plate. Put the hour hand on the clock as a friction fit and then the minute hand with its nut.
5. Set the chime with time. After the new movement is installed, you will notice the clock will chime 5 minutes before the hour or after the hour, or 8 minutes, or whatever. The idea being that it won’t chime when it’s supposed to.
This fix is very easy but some people have a hard time believing it is as easy as described. Please read this text carefully. Take the minute hand off of the clock, this is the longer of the two hands. With this minute hand off of the clock, turn it upside down and you will see it has a square hole where it attaches to the clock. This square hole is in a bushing that will rotate WITHIN the minute hand itself. So just use needle nose pliers to turn this bushing so the square in the bushing will rotate. Then put the hand back on the clock and see if it’s pointing to the correct place where it chimed. Then set to time.
