Quartz Clock Movement Removal
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.
Clock hand removal
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
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.
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.
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.
What to measure
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.
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
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.
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.
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.

Seiko Chiming Clock MovementSeiko durability in a quartz chiming clock movement. Plays choice of Westminster or Whittington on the quarters and then strike out the hours. Has an auto night feature if the chimes are not wanted at night. If set, it will not chime between 10pm and 6am. The pendulum, bob, clock hands and the second hand are sold separately.
Pendulum or NonThe most compact chime pendulum unit offered here at Clockworks with 3 1/4" x 5 1/4" x 1 5/16" for measurements. Offering both the pendulum version and the non pendulum version. Of course the pendulum has nothing to do with the time keeping and is just for looks.

MovementThe Seiko Chiming Quartz Clock Movement is the most durable we have to offer and has the fewest returns
SoundThe unit can be set to play either Westminster or Whittington chime. It will chime on the quarter hours and then strike out the hour on the top of each hour. There is a volume control and also there is a optional auto night silence switch for night silence.
HandsAny of the quartz hands offered 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. A second hand can be used only if its wanted. All hands are sold separately, as well as the pendulum and bob, and is offered here as well.
PendulumThe pendulum rod is 16 inches at its longest length. However, it can be shortened to any length you wish because there are one inch segments that allow you to measure, bend and snap it off at whatever length you need. The pendulum 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. If a pendulum is not used the pendulum swinger can be locked to one side and not use it.
Mounting PostThe Seiko movements threaded post comes in two lengths. This is the wide 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. The post lengths available for this unit is either 5/16 long or 11/16 long. The posts are all 5/16 wide, and fit into a ⅜ dial hole.
QU30 Chiming Seiko Clock-Instructions
The following are the QU30 Chiming Seiko Clock-Instructions.
Please Note: The movement will not chime the quarter hours while the time is being set. Only the hourly chimes will operate during the setup process. The quarters will start when the clock is set and about 90 minutes after being left alone to chime on its own.
- Push the HOUR hand onto the post at the 6 o'clock position.
- Place the MINUTE hand at 12 o'clock and tighten the minute hand nut.
- Press the SECOND hand onto the shaft at the 12 o'clock position (if using one). Hands are now set to the CHIME of the motor.
- Using the hand setter, on the upper right side of the movement, turn the hands clockwise to the correct time of day.
- Insert one C-cell battery. The motor will now run and set for the correct chime and time of day.
- To listen to 24 hour chime and strike, place the AM / PM switch in the LEFT position. For night-time silence (between hours of 11:00PM and 5:45AM) place the AM / PM switch in the RIGHT position.
- The song switch on the left side of the movement is to select Westminster or Whittington. The display shows a 1 or 2. Slide the switch to whatever song wanted.
- This concludes the QU30 Chiming Seiko Clock-Instructions. Now the clock is properly set up.
Making it chime on time
Troubleshooting the QU30 Chiming Seiko Clock-Instructions
First, find out if the clock chime is correct. It does not matter what time it is. The hands need to point to the time the clock thinks it is. Which means where the clock is chiming.
So when the clocks chimes, make note of how many times it does so. Then remove the hands. Put them back on to point to the number of chimes it rang. In other words, 3 chimes means put the hands on the clock to point to 3 o'clock. The final step it to set it to the correct time by either the rotating the setting knob or rotating the minute hand slowly in a clockwise manner. Always rotate it clockwise.
Additionally, if the clock minute hand will not point exactly to the 12, do this. Find the circle setting knob on the back of the movement and hold this still with fingers so it will not move. At the same time, point the minute hand to the 12 where it needs to be. Let go of both and it will be correct from then on forth.
