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, 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.
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.
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. Of course, this is done by removing the hands from the clock.
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 threaded post (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.
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.
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 needed. The threaded shaft 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 called 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.

Premium Chime Clock MovementThis QU40 is a premium chime clock movement that has a four melody chime. In addition, this unit is unique as it has a light sensor. If the lights are off, or it does not see light, it will not chime. Of course, this movement also has an overnight automatic shut off that is an option as well. The pendulum, clock hands and second hand are sold separately.
Premium Chime Clock Movement QU40 Sounds like a mechanical clockWith our one year warranty and their amazing Tubular Chime sound, these movements should provide years of worry free performance. This unit has a premium sound quality and takes two C-cell batteries. Also, the speaker is on a wire so it can mount anywhere in the clock case with two wood screws.

Premium Chime Clock Movement QU40 MovementThe new QU40 quartz movement has step motion timekeeping accuracy and includes a time setting knob on the back of the unit. Additionally, the knob on the back is so the time can be set by the back, in case the hands are not easily accessible from the front. This is a pendulum unit however it will run with or without the pendulum. In other words, the pendulum motion does not have anything to do with the timekeeping on this unit.
SoundThis is the only unit with four options for the chime. Choose between Westminster chime on every quarter and then striking out the hour, or choose Westminster or Ave Maria or BimBam on the top of the hour only. The light sensor is easy, if it does not see light, it will not make noise. Thus, the sensor is on a wire so it can tuck in where it can detect if there is light or not. This can be anywhere in the case that light would fall upon.
HandsAny of the hands we sell for quartz clock movements will fit this unit. As far as the quartz units go, we only have the standard American “I” shaft units and hands. Specifically, this means the hour hand will have a round hole and the minute hand would have a oblong hole. Additionally the hour hand goes on as a friction fit, then the minute hand goes on the upper post with its nut. Similarly, use a second hand only if you want to. This is an optional feature. Furthermore, all hands are sold separately and are offered here as well.
PendulumThis movement has an optional pendulum that is 16 inches at its longest point. However, it can be shortened to anything less than 16 inches with ease. In fact, the pendulum also 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, it can be used with or without the pendulum. Likewise, if a pendulum is not in use, lock the pendulum swinger to one side if you do not want it to swing.
Mounting PostAlso, the movements threaded post comes in three lengths. This is the fat threaded part that takes the hex nut. To clarify, the length of the threads on the post is what we measure. Of course, 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. So the post lengths available for this unit are either 5/16 long or 7/16 or 11/16 long. Comparatively, the posts are all 5/16 wide, and fit into a ⅜ dial hole.

Premium Chime Clock Movement QU40 Instructions
- Connect the speaker to the movement
- Rotate handshaft clockwise until you hear a faint click sound. Then install hands at 5:00
- Insert the proper C-cell batteries into the movement. Note that the positive end of the battery faces downward.
- Double check to see that the hands are at the 5:00 position. Then press the gray RESET button at the bottom of the back side of the movement. This will set the electronic strike to 5:00AM. Rotate hands to 6:00 and note that it will strike 6 times. If everything is correct advance the hands to the correct time.
- Next, choose the melody in which you wish the movement to play. Note when in the 4x4 mode it will chime on the quarter and half hours as well as on the hour.
- When in the 4x4 mode, it may take a complete hour to correct itself after the time set knob is turned to the correct hour. However this is completely normal.
- For night chime silence, set the sound lever located on the back right hand side to PM 11:00-AM 5:45 Night off. This will be the auto night shut off mode and will shut the chimes off between 11 and 5:45AM. For 24 hours, move lever to the 24HR mode.
- The MONITOR button is used to demonstrate the hourly chime.
- The SET button is used to advance the strike one hour. However, this will not move the hands
- Very Important! Never turn the hands backwards. If setting the time from the back of the clock, turn the time set knob on the back of the movement so the hands move Clockwise only. Likewise, if setting the clock from the front, turn hands Clockwise only.
