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. Removal needs access to both the back side and the dial side of the clock dial. There is no many case designs it would not be possible to cover all of this information. The clock case went to together so it comes apart that is the logic.

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 users 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.

Minute hand

Quartz clock movements have two styles of minute hands. One style 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 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 by the pliers it only requires fingers to unscrew it.

Hour hand

The hour hand is only a friction fit by its round mounting hole. The movement's hour tube is tapered wider on the low end of it. This makes the hour hand friction fit only. Just twist the hand and pull it toward you until it comes off.

Second hand

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

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.

The movement is now installed

This applies to all battery operated clock movements available on clockworks.com. Such as chiming quartz, time only, with the only exception being the clock inserts.

Quartz clock movement measuring

Please select the post length when ordering a new quartz clock movement. This post will need to be able to go through the thickness of the dial 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

Clockworks.com offers multiple post lengths on the quartz movements. When replacing a quartz clock movement you will need to measure the post on the old unit. This is so it can be matched it up with the new quartz movement. The post is the part that goes through the dial (face) and mounts from the front. This applies to all clockworks.com quartz movements, including chiming quartz, and time only quartz movements.

Length depends on dial thickness

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 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

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 Definitions

Definitions listed are for the quartz clock movement products only. They are the terms used in replacing a quartz clock movement . This is to clarify what the names of the parts are and what we are referring to when they are explained. It is easy to replace a quartz clock movement and does not take long if it is known what the parts are called.

Clock Dial

Dial =

The clock face that the movements post goes through is called a dial. This is the face of the clock with the numbers on it. They are available in either Arabic (regular) numerals or Roman (XII for 12) style. Dials also come in many shapes or sizes. Larger sized dials may require a High Torque clock movement instead of a Low Torque. A High Torque unit is used when the dial is over 10 inches wide. This is measured from outside the 9 to outside the numeral 3 and we call this the time track diameter.

Quartz Clock Movement Definitions of Terms

Post =

The post is the threaded section that mounts the movement to the back of the dial with a hex nut. They all come 5/16 wide except for the QU22 unit. The QU22 has a 7/16 wide threaded post rather than the 5/16 like the rest of the quartz units. The lengths are variable and is chosen upon ordering the clock movement.

Quartz movement clock Hex Nut

Hex Nut =

A six sided nut that threads onto the movement post. This is the nut that attaches to the post that goes through the dial from the back to the front. It secures the movement to the back of the clock dial. This should be tight enough so the movement will not spin sideways if the clock case gets moved.

Quartz Clock Steel Hanger

Hanger =

Included but optional, this is the steel part that allows the clock to hang on the wall. This slips over the movements hand shaft and threaded post before the movement gets mounted to the back of the dial. Therefore you would have the hanger top of the movement and will allow it to be hung on the wall. These are usually made of steel however sometimes comes in aluminum instead. All of the time only quartz clock movements will have this hanger but not the pendulum units.

Quartz Clock Movement Hands

Hands =

Also sometimes called pointers needles or arms, these are the things that point to the time. The hour and minute indicators to tell you want time it is. Upon ordering the clock hands it will ask for the length of the minute hand needed. This is measured from the center of the mounting hole to the end of the minute hand only. The hour hand comes with the minute hand but is just proportionately smaller so it will look right. The minute hand we offer for the quartz units have an oblong mounting hole and the hour hand has a round hole. This is refereed to as the American standard "I" shaft style. In China they use a different style with round mounting holes in both the hour and minute instead. All of our quartz clock hands fit the quartz clock movements we sell and are the standard "I" shaft as described.

Quartz Clock Movement Second hand

Second Hand =

The optional skinny pointer that ticks out the seconds. The mount on the quartz second hands are just a press and friction fit. There is a post that sticks out of the backside to mount it. This tube fits over a pin that is inside of the quartz clock movement's hand shaft post. The second hands post fits down into the end of the hand shaft and mounts via friction fit. There are two styles of time only quartz clock movements, step motion and continuous sweep motion. The step unit will run this second hand in a jumpy one second intervals. The continuous sweep movement runs the second hand in a fine non stopping sweep motion around the dial instead.

Low Torque (For dial diameters 3" to 10")

Low torque clock movements are small, accurate and well made. They come with the hanger to hang it on the wall if you want too, and the mounting hardware. 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 face and nothing else, then you can put you're hour hand on, and then the minute hand with its nut.

High Torque (Any dial diameter 3" to 30")

High Torque 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.
AA Cell High Torque #HT1 High Torque Clock MovementsThe 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.

Quartz Clock Hands

Quartz Clock Hands that will fit any battery movement 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. An American style has an oblong mounting hole in the minute hand and a round hole for the hour hand that fits what is known as an "I" shaft. All of the hands offered here fit "I" shaft movements only. In other words all of them will fit the quartz movements that we sell.

Quartz clock hand compatibility

When replacing a quartz clock movement, your old hands may fit the new movement just fine. If there is an oblong hole in the minute hand, chances are it will fit. The hour hand will fit the new quartz movement either way. Only the minute hand (the longer of the two hands) is where the concern is. If in doubt, it's best to just get new hands for your new movement upon checking out. This way it will be all set. You will have everything you need for a smooth movement swap out.

How the hands come

These come as a set, but only the minute hand is measured when replacing them. It is measured from the mounting hole to the tip. The shorter hour hand comes with the minute hand and is just proportionally smaller. For larger dials more than 10 inches wide, see our High Torque movement and hands section. Second hands will fit the high torque clock movements however they do not make them very long.

Mounting quartz clock hands

Mounting is easy. The hour hand goes on first as a friction fit. Just twist and push it 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 then you would use the cap style nut so it looks pretty.

Quartz Clock Second Hands

Quartz clock second hands are mounted with a tube under the hand that fits by friction fit onto the quartz clock movement. To install the hand all that is needed is to put it in hole at the end of the hand shaft. 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. 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 are used on larger clock dial diameters. These hands require a high torque clock movement that is run by a battery. These hands are for the American standard "I" shaft battery powered quartz clock movement. The minute hand will have an oblong mounting hole and the hour hand will have a round one. The minute hand mounts on the oblong shaft on the clock movement.

Mounting the hands

Mounting the clock hands to the high torque clock movement is easy. The hour hand is a friction fit and gets pushed onto the post first. This gets pushed down as far as it will go without it touching the clock face. Next is the minute hand which has the oblong hole. It gets mounted on the tip of the oblong shaft on the movement and secured by the hand nut.

Hand nuts note

Two hand nuts come with a new clock movement from clockworks.com. One is used with a second hand and has a hole in it. The other nut is a cap nut which has no hole and covers the entire tip of the post. The doughnut hand nut is used with a second hand.

High torque hands checklist

That concludes the mounting procedure. Things to look out for: the hour hand is not rubbing the dial and the minute hand is not rubbing the hour hand. Be certain the minute hand is not rubbing the glass door or anything else during its sweep around. These hands should be parallel and cannot come in contact with anything.

Sold as a pair with both hour and minute hands. Styles vary depending on length and the longer hands will have the tail counter balance.
