Quartz Clock Movement Removal
Quartz Clock Movement Removal is done in the following way for most units besides movements made in Germany. The first step to replacing a quartz movement, is to be able to get to the movement from the back and also the front where the hands are.
1. Getting to the dial - There are many case designs and styles and there is no telling what way you're clock case is made to get to the dial (face) of the clock. Sometimes it is very easy to get to the dial and hands, other times the dial is covered with glass and may require you to figure out how the clock case was put together, so you can take it apart enough to get to the dial. You may have to remove some screws, or if there is a bezel it maybe required to bend the bezel tabs some to get it off. Once you're at the point where you can remove the hands and also the back of the quartz unit, you're good to start replacing the unit.
2. Removing the hands - 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 Removal always needs the hands removed. There are two styles to the minute hand, the kind that has the nut holding it down and the kind that is only on by friction fit with a round hole in the hand. The friction fit with no nut style just pulls straight off like the second hand did. The other style (the kind we sell) has the nut on the top of the minute hand to hold it down. To take this off, hold the minute hand still as you turn the nut to the left with needle nose pliers to loosen the nut so you can take it off with you're fingers. 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.
3. Removing the hex nut - Then you will see a hex nut (six sided nut). use the same needle nose pliers to just turn the hex nut some to the left so it can be unscrewed with the fingers. With the hex nut removed the quartz clock movement will just fall out of the back side of the dial (face).
Quartz clock movement installation
Quartz clock movement installation is done in the below sequential order to get the clock up and running.
The first step is to get the old unit out of the way by removing the hands from the clock, and then taking off the hex nut that is located under where the hands used to be.
The movement will fall out the back of the clock dial and you then have it 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.
- Place hanger on post (optional)
- Place black washer on post (optional)
- Put post through the clock dial face
- Slide the brass washer onto the post of the movement that is sticking out of the clock dial face
- Put hex nut on post and tighten to hold movement to the back of the clock face – you may use needle nose pliers to get a tighter fit, however do not crank it down so tight that it ruins the clock face.
- Push hour hand on the post (smaller of the 2 hands with round hole). This is a friction fit and should be pushed all the way down on the post without it touching the clock face.
- Put the minute hand on the post
- If using a second hand, skip to step 9. If you are not using a second hand, screw the cap nut on. You are done.
- If using a second hand, screw the small donut on top of minute hand and then push the second hand onto the pin in the center of the unit. You are done installing you're brand new quartz clock movement !
Quartz clock movement measuring
Quartz clock movement measuring is done by measuring the post that sticks out the movement, that goes through the dial and attaches with a hex nut. The hex nut is a 6 sided nut that secures the movement to the back of the clock dial face.
When replacing a quartz clock movement it is done this way, you will need to measure the post on the old unit, so you can match it up with your new chiming quartz movement.
The post is the part that goes through the dial (face) and mounts from the front.
The sequence of installation of these fine quartz clock movement is done by these steps. First you put the hanger on the new movement if it has this option, then comes the rubber washer next. Both go over that fat post that sticks out the front of the movement. Then the movement goes through the back of the dial toward the front of the dial, so the fat threaded post sticks out the front of the dial some. Then you put the hex nut on to secure the movement to the back of the clock dial. Now you have the movement secured to the dial and only need to put the hands on. The hour hand goes on as a friction fit just twist and push. The minute hand has an oblong hole and this goes onto the oblong shaft that stick out of the fat threaded post that takes the hex nut. The minute hand goes on, and its nut holds the minute hand on the post. The movements come with two different minute hand nuts actually, one is a cap nut if no second hand is used, the other one is a doughnut style and this is to be used if there is a second hand involved. The intent is to use one nut, and toss out the other. Now you have the clock mounted with the hands installed. If there is a second hand this goes on just by a friction fit, last. Just stick it in the hole at the end of the hand shaft as a friction fit. Point the hands to whatever time it is and your done.
Measuring quartz post lengths
Measuring quartz post lengths is needed to determine if the quartz clock movement is to fit correctly on the clock dial. Its like this, the post has to stick out the front of the clock dial enough to put on the hex nut to secure the movement. The movement needs to be secure to the back of the dial (clock face) so it will stay and not move around. If its not secure all that can happen is the movement will turn and the hands will point to a different time then what was set.
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 (the face,or you can say the thing with the numbers on it).
If replacing a movement and not building clocks, it maybe easier to just measure the old post instead. Remove the quartz clock movement and measure the threaded post that takes the hex nut (6 sided nut). This fat part of the hand shaft is the part that secures the movement to the dial and is all that needs to be measured. The old unit fit before so it only makes sense that 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, time only quartz

Quartz clock movement glossary
the Quartz clock movement glossary below are the terms typically used in the quartz clock movement realm. Hopefully this will bring some clarity to the instructions on how to build clocks with quartz clock movements or replacing the same on units that gave up the ghost so to speak.
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 and we would call this type of quartz clock movements a continuous sweep unit. If it jumps from one second to the next we call it a step motion quartz clock movement. 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.
High Torque (Any dial diameter 3" to 30")
High Torque Quartz Clock Movements are geared special on the inside of the unit stronger as to take more weight. The C cell units are stronger than the AA units and would also last longer with the very long hands. The post that is being measured is as described on the above diagram. This is the threaded portion of the movement that goes through the dial face and needs to be long enough to mount the hex nut onto this post, in the front of the dial face. This means the movement is just mounted to the dial and nothing else, then you can put you're hour hand on, and then the minute hand with its nut.
The AA high torque quartz clock movements are much stronger than the low torque models. They have a threaded post diameter of 5/16 and a case dimension of 2 1/8 x 2 1/8 x 1/2D. The long hands for these movements are offered below.
Every High Torque Quartz Clock Movements comes with the mounting hardware and also a metal hanger to mount it to the wall. We offer a large variety of hands on this same webpage also.
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 and mounts to the oblong shaft on the clock movement.
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, twist and push toward the dial, it will stay there by friction only. 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.
Clock Numerals - Dial Numbers
Clock Numerals - Dial Numbers are used to either find replacements for numbers that have fallen off the clock dial or to create your own clock dial out of whatever material you would like to make a clock out of. The sticking numbers have a peel and stick back, but sometimes its required to use some more glue to secure them. The best glue to use with these are the clear epoxy that you mix and it dries in about 5 minutes clear. The brass numbers and the largest sized plastic numbers do not stick on there own, and the ones that do peel and stick should be secured with the epoxy also as described, so its best to get the epoxy with the numerals.
These Numerals have a sticky back to them so they will mark your dial or wall.
These Numerals can be drilled and screwed onto a surface to stay more permanent.
