Clock Movement 141-040 141-070 Compatibility
The compatibility between the clock movement 141-040 and 141-070 needs explanation and clarification. At one point in time the same number was used for both versions .
What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.
It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible. To make it a gong strike, we only need to remove one of the hammers with its wire and take off the bells.
The reasoning behind this is simply the cost of importing the movements from Germany. There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible.
In most cases the customer leaves the bells and ditches the gong as the sound is better.
What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types.
So what was previously known as a 141-070 is now referred to as a 141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If having the bells get the 141-070 and if it has a gong order the 141-040.
How do you add a 31 day calendar feature/gear to the Hermle 141 movement series. Is there an additional cost?
What are the numbers off of the back plate of the clock movement itself? If it is hard to get to, usually you can stick a cell phone up behind the movement and get a picture of the numbers. Or through the side access panel if there is one.
Not off the paper work, not off the wooden case, but the movement stamp itself

I broke the suspension spring on my 141-070 movement. What is the correct replacement (mine hangs from the top of the clock, unlike some photos I’ve seen, and mine is not marked Hermle.)
Also, is it a difficult to replace the spring?
Thank you for any help you can give!
