Quartz Clock Movement Removal

This note explains quartz clock movement removal from the case. The following does not apply to quartz units made in Germany or inserts.

To remove the movement, you need access to the back of the clock and the front side of the clock dial. There are so many case designs it would not be possible to cover all of the different variations.

The clock case went to together so it comes apart. It may take a bit of probing but there is always a way to take it apart because it went together.

Getting access to the dial area

There are many case designs and styles and there is no way for us to know how the current specific clock went together. Most of the time the removal process is very easy but of course there are some instances where it is not user friendly.

Thus, it is on the users end to be able to access the dial and movement area to continue with the swap out.

Clock hand removal

Quartz clock movement removal always needs the hands to come off first. There are two reasons for this.

First, need to have access to the hardware that mounts the movement. Second, there is no way to take get the movement out of the clock if the hands are still on it. They certainly will not fit through the hole in the clock.

Quartz Clock Movement Removal - Minute hand

Quartz clock movements have two styles of minute hands. One style has a nut that holds it in place and the other style is a friction fit.

The friction fit has no nut and just pulls off with a twist and pull. The second style has a minute hand nut to secure the minute hand. Removal is done by turning the nut to the left with needle nose pliers. Once the nut is loose it only requires fingers to unscrew it.

Hour hand

In a Quartz clock Movement removal task, the hour hand is only a friction fit. Thus, the hour tube tapers down on the movement, meaning it is wider on the low end of it.

This makes the hour hand friction fit only. Just twist the hand and pull it until it comes off.

Second hand

The second hand pulls straight up and off if the clock has one.

Quartz clock movement installation

In essence, this is a quick step by step practical guide for the quartz clock movement installation. The first step is to get the old unit out of the way. Sometimes this is straightforward and sometimes it can be tricky.

Of course, this is done by removing the hands from the clock. Some clocks will have a glass bezel that will have to be taken off in order to get to the hands. Every clock is different so thoroughly look your clock over to see how it was put together.

Then remove the hex nut that is on the post where the hands were. In essence, the movement will fall out the back of the clock dial.

On occasion, the movement will have glue holding it in place. So, if this is the case, very gently pry the movement off of the back of the clock with a screwdriver.

Now it is out of the way and installation of the new quartz clock movement bought from Clockworks can be done.

Likewise, Quartz clock movement installation is usually very easy. Altogether, these are the assembly instructions for the time only quartz clock movement into the clock case.

Sequential order of installation

  • 1. Place the steel hanger over the post with the threads (optional)
  • 2. Place black rubber washer on the post next (optional)
  • 3. Start mounting the movement by putting the post through the dial
  • 4. Then on the front of the dial, slide the brass washer onto the post of the movement.
  • 5. Put the hex nut on post and tighten so it holds the movement to the back of the clock face.
  • 6. Push hour hand on the post by friction fit
  • 7. Put the minute hand on the post
  • 8. If using a second screw the doughnut on to hold the minute hand in place. Then install the second hand now by friction fit. The post just sticks onto the pin at the end of the post.
  • 9. If not using a second hand just secure the minute hand with the pretty cap nut.

The movement installation is now complete

Naturally, this applies to all clock movements that take a battery available on Clockworks.

For example, chiming quartz, time only, and high torque. Of course, the exception to this would be clock inserts.

Quartz clock movement measuring

Please select the post length when ordering a new quartz clock movement. Of course, when doing quartz clock movement measuring, remember the post will need to be able to go through the thickness of the dial face.

Also remember that the dial may or may not have a wood backing to it. With a wood backing the clock dial or face would be thicker and thus would need a longer post.

Clockworks offers multiple post lengths on quartz clock movements for this reason. In other words, the post has to be long enough to go through whatever thickness we are calling the dial.

How to measure quartz clock movement post

What to measure

Clockworks offers multiple post lengths for quartz movements. When completing a quartz clock movement measurement, you will need to measure the post on the old movement.

This is so it can match up with the new quartz movement. To clarify, the post is the part that goes through the dial (face) and mounts from the front and what is in a quartz clock movement measurement.

This applies to all Clockworks quartz movements, including chiming quartz, and time only quartz movements.

Length depends on dial thickness

When working on a quartz clock movement measurement the post has to be long enough to go through whatever thickness that the clock face/dial, might be. The length of the threaded portion of the post/shaft, is the measurement that you need.

The shaft with the threads needs to go through the dial/face of the clock from the back to the front. It needs to be long enough for a small hex nut to screw onto it. It can’t be too long or the hands will not move correctly.

Clockworks has a variety of quartz clock movement lengths to accommodate a variety of different materials since some are wood and some are metal and some are plastic, etc.

Measuring quartz post lengths

Above all, when replacing a quartz movement it means measuring quartz post lengths. Subsequently, the post will stick out through the front of the clock dial.

Of course, there needs to be enough threads sticking out for the hex nut to be put on. Hence, the movement will be held in place to the back of the dial (clock face) and will not move. Sometimes if the clock has glass over the face it is possible for the post to hit it.

Therefore it is important to measure the quartz post length correctly. In other words, if the post hits the glass, the hands will not be able to move. Thus making the clock not work.

Use the chart if building a clock

With that being said, find the correct quartz post length by using the chart below. So remember, the threads on the post need to be at least 2/16 longer than the thickness of the clock dial.

To clarify, a clock dial is the face (also known as the thing with the numbers on it). As always, email us if there is any question.

Measuring quartz post lengths if replacing a clock

If replacing a movement and not building a clock, it is easier to measure the quartz post length of the old movement.

Before measuring, remove the movement first by taking off the hands and then the hex nut. Next, measure the length of the post that has the threads that the hex nut was on.

In short, only measure the fat part of the hand shaft that we call a post. Also, never include the part that the hands go on when measuring the post length. All in all, the new unit needs to be the same post length as the old movement.

Overall, this applies to all quartz clock movements available on Clockworks such as chiming quartz and time only quartz.

Time - Pendulum Clock Movement

This time and pendulum quartz clock movement will run a light weight pendulum that is 16 inches at longest. The quartz pendulum we offer is 16 inches (406mm) at its total length, however you can be shorten it.

The back of the pendulum rod has notches each inch up the rod, so all that is required is to bend and snap at the desired length. The pendulum comes with its round pendulum bob for the bottom swinging portion. This pendulum bob is available in three diameters. The pendulum with its bob is a separate purchase.

May need new hands for the clock movement

The old hands will usually work on the new pendulum quartz unit. However there are some instances where they will not. If the old unit has an hour and minute hand both with round mounting holes, they will not fit the new movement. It is best just to get the new hands either way so it does not have too be a concern. They are sold as a pair but you only measure the minute hand. Measure the minute hand from the mounting hole to the end.

Post Length Measuring

To replace a pendulum quartz clock movement, measure the post with the threads that the hex nut screws onto. This is the wide post that the nut with 6 sides screws onto only. The section that the hands mount too will extend beyond this measurement by 1/4 inch.

Time and pendulum quartz clock movement with a 16 inch pendulum that you can shorten to whatever less length. The unit itself measures 2 1/8″ x 3 3/4″ x 7/8″.


Any of the hands Clockworks offers for quartz clock movements will fit this unit. The hour hand will have a round hole and the minute hand would have a oblong hole. The hour hand goes on as a friction fit, then the minute hand goes on the upper post with its nut. You can use a second hand if you want. All hands are sold separately and is available here as well.


This clock can run a light weight pendulum up to 16 inches at its longest, sold separately. However it you can shorten it to anything less than 16 inches with ease. The pendulum we offer has three bob diameter options to choose from, the bob is the round disk at the bottom of the pendulum rod. Please note although this is a pendulum unit, you can use it with or without the pendulum. If you do not use the pendulum, you can just lock the pendulum swinger to one side and not use it.

Mounting Post

The movements threaded post comes in three lengths. This is the fat threaded part that takes the hex nut. This post length is what we measure, the actual part that the hands go onto sticks out another ¼ inch beyond this measurement, but we do not count that in the measurement. There are many post lengths available for this unit. The posts are all 5/16 wide and fits through a ⅜ wide dial hole.

The swing

Get the case width, minus bob diameter and minus 6 inches. This is the approximate minimum inside case requirements. In other words the bob usually needs 3 inches to swing back and forth on each side of it. Depends of coarse on bob diameter and length but this rule is for a full length pendulum with its widest swing. Full length is 16 inches, shorten to anything less. It is best and recommended to of course get the movement first and see what the swing is in live action before building a clock case.

How do I get hold of the company re: clock that has never worked; it’s not the batteries.

Re the “Time – Pendulum Clock Movement”. on the drop down menu the longest thread is 13/16. Is there a 15/16?? If not would 13/16 work with dial thickness of 3/4
