Hermle quartz hand shaft measurement
How to measure the Hermle Quartz hand shaft. Measure the entire post that sticks out of the movement. From the plastic base all the way out to the tip of the post. This measurement is different from how all other quartz units are measured.
Hermle used three hand shaft lengths on their base units. These lengths are 16mm, 21mm, and 26mm. There was a time some of the 26mm had an internal modification to create an extremely long hand shaft. It was something like 1 1/4 or 1 1/2 inches. If working with one like this there is no replacement for this unfortunately.
Hermle to regular conversion
The following is the conversion from the Hermle Quartz hand shaft length, to the length of the threaded post to order from us.
- 1. Measure the hand shaft on your current Hermle quartz clock movement
- 2. Convert to the post length needed with the below information
- 3. Order whatever movement you would like from us with that post length.
- 16mm (About 5/8″) = Get a 5/16 post
- 21mm (About 3/4″) = Get a 7/16 post
- 26mm (About 1″) = Get a 11/16 post
Next step to replace the Hermle quartz
Now that the old unit is out of the way and the conversion is known from the old hand shaft length to the new post length, we are ready to shop for a replacement. The next step is to take note of the overall size of the new movement and be sure that it will fit dimensional behind the dial.
The new unit may be taller or wider so be sure it will fit in the clock case. If verified its ok, we can pick a new unit with the post length that was converted. Be sure to get new hands as well. They are on the same page as the product. The old ones will not fit without modifications.
I have contacted you before, and still want to replace the clock movement in my pendulum clock. I got a little phased when told I needed to measure the shaft. However, after noting that I need to measure the shaft, (from your information above), I need to know how to do this. Do I have to remove the movement, (i.e. hands etc), and then measure? There seems to be a small “nut” holding the hands on the dial. Is that removed with pliers? Will the movement be glued to the back. Sorry, so many questions.It is a Hermle Quartz 2200
Removing Hermle Quartz Movement
Removing A Hermle Quartz movement is done by removing a unique mounting nut. It is not the typical 6 sided hex nut like most units have. Instead, it is a nut that has slots on both sides of the hand shaft. It’s just a different way of securing the Hermle Quartz movement to the back of the dial. The slots on the nut have a deep collar with threads that go through the front of the clock dial to screw into the movement. This is in opposition to the common style quartz unit that has a post with threads and utilizes a hex nut. That is the hex nut on the front of the clock face to secure the movement.
Double sided sticky tape method
If the movement mounts to the dial by double sided sticky tape, carefully pry the movement off the back of the dial leaving the dial in tact.
Steps to remove a Hermle quartz
Remove the second hand. Pull it straight and it will come off.
Remove the minute hand nut by turning the nut to the left while holding the hand still.
Take off the hour hand, it is a friction fit only. Pull toward you.
Take off the nut. It is an unusual nut that holds the movement. This nut has a slot on each side. It may be on tight, so it is not always easy to take this off. A special tool to take this nut off is no longer available, will have to improvise. Using two big flat screw drivers, put one on each side of the nut and twist. Be careful not to scratch the dial, because it is easy to slip and make a long scratch on the face.
The movement will now fall out of the back.
Removal is complete
With the Hermle quartz movement out of the clock case, now we can determine the best substitute movement. There are several to choose from.

Hello James,
Thanks so much for the information. I have been able to remove the old movement, and I believe the hand shaft to be as near as I can see, to 20mm, which according to your notes would mean a 7/16 post. The way the movement was fitted to my clock, there is a block of wood through which the shaft goes, and then out to the clock face. It was quite firmly attached and easy to remove.
So, please send me a replacement movement for the Quartz 2200, and invoice me. I will pay by bank transfer if you have that arrangement, or Credit card.
Please let me know what you intend doing.
Again, many thanks for your help.
Regards,

Hi,
Please order online, QU3 is the closest unless you would like the clock to chime with the new unit

Hello James,
I have tried to purchase the QU3, as you suggested. However, the site does not allow me to insert the relevant information regarding Country, State, Post Code, etc., and the sale cannot continue. Have I gone to the wrong site? If so, please send details of how I might resolve this.
many thanks,
Gordon Bezear

Hi, no I am not a U.S. resident. I thought you were a company here in Australia. I might try and see if there is anyone in this country who can help. Sorry for any inconvenience, but thanks so much for your help.
I understand. Have a great day and good luck
