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 and also clock inserts. It is required that there is already access to both the back side and the dial side of the clock. There is no many case designs it would not be possible to cover this information. The clock case went to together so it comes apart that is the logic. So in whatever way we need to be able to access both the front dial and the back of the movement to continue.
Getting access to the dial area
There are many case designs and styles and there is no telling what way you're clock case is. Most times this is a very easy thing to do but of course there are some instances they do not make it user friendly. It is on the customers end to get to the dial and movement area to continue with the swap out.
Clock hand removal
Quartz Clock Movement Removal always needs the hands removed first. This is so there is access to the hardware that mounts the unit.
In the vast production of quartz clock movements exists mainly two styles of minute hands. One has the nut holding it secure and the other style is only on by friction fit. The friction fit has no nut and just pulls off with twist and pull at once. The other style has the nut on the top of the minute hand to hold it down and this is the style we work with here at clockworks.com. Removal is done by holding the minute hand while turning the nut to the left with needle nose pliers. Now it can taken off the rest of the way with the fingers instead of using the pliers.
Next is the hour hand, this is only a friction fit with a round hole in the hand, the tube its on is tapered fatter as it goes down into the movement. Just twist the hand and pull it toward you until it comes off.
If there is a second hand on the clock, it only needs to be grabbed with the thumb nails and pulled straight off of the clock to take it off.
Quartz clock movement installation
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. This is done by removing the hands from the clock and then the hex nut that is located under where the hands used to be. The movement will fall out the back of the clock dial. now it is out of the way and you can put in your new fine quartz clock movement you bought from clockworks.com. Quartz clock movement installation is very easy usually. 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. Slide the brass washer onto the post of the movement that is sticking out of the clock dial
- 5. Put hex nut on post and tighten to hold 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 hand install now by friction. The post just sticks into the end and use the doughnut.
- 9. If not using a second hand just secure the minute hand with the pretty cap nut.
Quartz clock movement measuring
When the quartz clock movement is ordered it will ask for the post length. A hex nut will be on this threaded post that is to be measured. A hex nut is a 6 sided nut that secures the movement to the back of the clock dial. A clock dial is the thing with the numbers on it also called a clock face. The dial may or may not have a wood backing to it. With a wood backing the dial or face would be thicker and need a longer post. Clockworks.com offers multiple post lengths on the quartz movements for this reason. The post has to be long enough to go through whatever thickness we are calling the dial.
What to measure
When replacing a quartz clock movement you will need to measure the post on the old unit. This is so you can match it up with your new quartz movement. The post is the part that goes through the dial (face) and mounts from the front. This applies all clockworks.com quartz movements including chiming quartz, time only quartz.
Measuring quartz post lengths
To replace a quartz clock movements we need to do some measuring to get the post length. The post has to stick out through the front of the clock dial. It has to stick out on the front side enough to put on the hex nut on. The movement would then be secured to the back of the dial (clock face) so it will stay and not move. So the movement will turn and the hands will point to the right place where it was set.
Use the chart if building a clock
The below chart will tell us what size post is required to be able to go through the thickness of the clock dial. Again, all that is needed is the post to be longer than the thickness of the clock dial. A clock dial is the face or you can say the thing with the numbers on it.
Measure if replacing a clock
If replacing a movement and not building clocks it maybe easier to just measure the old post instead. Remove the quartz clock movement first by removing the hands and then the hex nut. Next measure the threaded post that the hex nut was on only. Only measure the fat part of the hand shaft that we call a post, this is the part that takes the hex nut only. This is the part that secures the movement to the dial and is all that needs to be measured. The old unit fit before its the correct post length you will need for your brand new quartz clock movement. This applies to all quartz clock movements available on clockworks.com. Such as chiming quartz and time only quartz.

Quartz clock movement glossary
The quartz clock movement glossary below are the terms typically used when replacing a unit. This will help us understand the instructions for building or replacing quartz clock movements.
The clock dial is the thing with the numbers on it that you tell the time with. Sometimes called the clock face and can come in any size or shape as long as there is indicators as to what the time is.Post =
Threaded portion on the movement that takes the hex nut. This is the fat part of the quartz clock movements hands shaft, and this part sticks through the back of the dial to the front to get mounted with a hex nut.Hex Nut =
A six sided nut that threads onto the movement post. This secures the movement to the back of the dial so it will stay there. The movements post sticks out just enough to get this hex nut on and so everything is secure and ready for the clock hands.
A hanger is the steel part to hang clock up on the wall and comes with the time only series quartz clock movements. The hanger is included with the quartz clock movement, but optional to use.Hands =
Quartz clock hands are measured by the minute hand only. They come as a set when ordered, the hour hand is smaller and shorter of course but we only measure the length of the minute hand from the center of the mount to the end. This applies to quartz clock movement hands only. (battery run)Second Hand =
The second hand is the skinny hand that goes very fast on the clock. There are two types of second hand motions, one will sweep around in a continuous fashion. These types of quartz clock movements are called a continuous sweep. If the movement jumps from one second to the next we call it a step motion instead. The second hands are mounted with a tube that is on the hand itself. This tube sticks friction fit into the end of the quartz clock movements hand shaft.
Time Only Quartz Clock Movements
Low Torque (For dial diameters 3" to 10")
(Step) 2 1/8 x 2 1/8 x 1/2M2 Low torque quartz clock movement with a 5/16 diameter threaded post. The Clock Movement the second hand will jump from one second to the next. If replacing, please get new hands also, as the old ones may not fit. They are offered below, and also in the checkout pages.
(Silent) 2 1/8 x 2 1/8 x 1/2A Continuous sweep Quartz Clock Movements do not make a ticking sound. When a second hand is used, the second hand will sweep around the dial rather than jumping from one second to the next. If replacing, please get new hands also, as the old ones may not fit. They are offered below, and also in the checkout pages.
High Torque (Any dial diameter 3" to 30")
C Cell High Torque #HT2The powerful C Cell high torque movement is the strongest on the market before getting into the electrical units. They have a threaded post diameter of 5/16 and a case dimension of 2-3/4"H x 2-3/16"W x 1"D. The long hands for these movements are offered below on this same web page.
Quartz Clock Hands
Quartz Clock Hands that will fit any battery movements we offer. There are two types of battery clock hands in the world. One is the China standard and one is American standard. The China way of using the hands are with round holes in both the hour and minute hands. The American style has an oblong mounting hole in the minute hand and a round hole for the hour hand and fits what is known as an "I" shaft. The quartz clock hands offered here all fit "I" shaft movements. In other words they all fit all the movements we sell.
Quart clock hand compatibility
If replacing a quartz clock movement, your old ones may fit the new movement just fine. If there is an oblong hole in the minute hand chances are it will fit. The hour hour will fit the new quartz clock movement either way. Only the minute (longer of the two ) are where the concern is. If in doubt its best to just get the new ones for your new movement upon checking out. This way its all set and you have everything you need for a smooth movement swap out.
How the hands come
These come in a set, so even though your measuring only the long hand the shorter one comes with it proportionally smaller. If you need them for a larger dial than 10 inches wide see our High Torque movement and hands section. If a second hand is used they are in a different section and sold separately as they are optional and not required to run on your new movement.
Mounting quartz clock hands
Mounting is easy, the hour hand goes on first as a friction fit, just twist and push on. The minute hand has an oblong mounting hole and goes on next. This goes on the "I" shaft top of the hand shaft of the movement with its nut. If you have a second hand you would use the nut with a hole in it. If no second hand is used than you would use the cap style nut so it looks pretty.
Quartz Clock Second Hands
Quartz Clock Second Hands come with a mounting post that is a tube sticking out of the bottom. This tube is what sticking into the top of the hand shaft post on the quartz clock movement. It is only a friction fit, press the tube in and its all installed. If by chance it is not climbing the hill from 6 o'clock to 12 o'clock, it may require tightening for a better fit. This is not the usual situation, but it does happen. To tighten the post for a tighter friction fit is easy because the tube that mounts the hand is split, so just squeeze slightly with some needle nose pliers and it will be tight again. Remount the hand as before and it should climb the hill no problem.
There are two types of quartz movements that run these hands. Step motion is a movement that the second hand jumps from one second to the next. Sweep motion, this is when it sweeps around with no stopping right around the dial.
High Torque clock hands
High Torque Clock Hands and used on larger dial diameters. These hands require a high torque clock movement that is run by battery power. These hands are for the American standard "I" shaft battery powered quartz clock movements. What this means is the minute hand will have an oblong hole. The hand mounts to the oblong shaft on the clock movement.
Mounting High Torque hands
Mounting the clock hands on to the movement is easy and is as follows. The hour hand gets mounted first, has the round hole and is only mounted via friction fit. As you put the hour hand on first just twist and push toward the dial. It will stay there by friction only but be sure its not rubbing the dial. Next is the minute hand, this has the oblong hole. It gets mounted to the oblong shaft and gets secured by the hand nut. There are two hand nuts that come with a new high torque movement from clockworks.com. One is if you were to use a second hand and it has a hole in it. The other nut is a cap nut and has no hole in it. The idea is to use the doughnut one if your going with the second hand if not use the cap nut so its better looking.
That concludes the mounting procedure. Just be sure the hour hand is not rubbing the dial, the minute hand is not rubbing the hour hand, the minute hand is not rubbing the glass door. These hands should be parallel and no contact with anything but its own mount.
Needs a High Torque Movement, comes with both hour and minute hands Styles vary depending on length. Longer ones have the tail counter balance.
