If I give you the brand and model number of my broken clock can you help me repair it?

Probably not. We deal only in the latest battery operated quartz movements. While it may be possible to use one of our movements to repair your clock, we have no way of telling because we can not reference the brand and model number of your clock to determine what you may need.

How difficult is it to install a quartz movement?

It is surprisingly simple. Just drill a 3/8" hole in front of your clock case, slide the movement shaft through the hole and secure in place by tightening 1 hex nut.

Do I need to use a second hand?

Most quarts movements have the ability to run a second hand. It is your choice to use one or not. If you feel the step second motion would be a distraction then don't use one. A special closed nut is available to cover the small hole showing when a second hand is not used.

Should I use a pre-assembled “fit-up” or a quartz movement with separate hands and dial?

Using a pre-assembled quartz clock fit-up is the easiest way to make a clock. The clock movement, hands, dial, lens and Bezel are pre-assembled and ready to be installed. All you have to do is make a clock case with the correct size hole cut into it. Just set the time, put in a battery and press into the precut hole in your clock case.

To use a quartz movement requires a little more planning, but is still fairly easy to do. If you choose to do this you have the flexibility of being able to se a standard time only movement, a pendulum movement, a chime movement or a variety of other possibilities. You can also choose from dozens of clock dials and over 40 styles of clock hands. If you decide to use a quartz movement with separate hands and dial, it is much easier to create a design that is truly unique.

Movements Motors

I am fixing an old clock that has very little clearance between the face of the clock and the glass.
What is the lowest profile motor/mechanism that you carry?

It depends on what size hands you need. The MVT0560 has a total shaft height of 1/4", but the hands we have availablefor it are under 2". The MVT7130A has a total shaft height of 17/32", and includes a choice of 45 pairs of hour and minute hands under 5".

I am looking for a motor that has the following features:
•High Quality chime
• Westminster chimes
•Automatic night time shut off
•Volume control

I’m looking for a battery operated clock kit that I can install on a plastic housing. The problem is the face is ~4” from the back where I would mount the battery mechanism.

The longest shaft length you can get a quartz movement in is 1-1/4” long. It’s an engineering limitation.

I need to find a replacement insert clock that would fit a 2-1/8″ hole, total width across face and bezel of 2-1/2″. I would prefer the bezel to be black. Do you offer this size and I am not seeing it on the website?

The closest size we have to what you are looking for is our 2-1/4" F59 series, which fits into a 2-1/8" mounting hole size.

Is it possible to find a pendulum movement with Westminster chimes

I’m building an art piece that uses a clock movement to rotate a large sheet of paper.
I’ve tried a few DIY clock repair movements (including a high torque) and they don’t have enough torque. I really I’d use the second hand and minute hand so it rotates faster, or find a movement that can be sped up.
Do you have anything that might work for me? I don’t really know enough about clock movements to look further than I have already.

Our high torque quartz continuous sweep movements have a balanced maximum weight for the second hand of 7 grams and 18 grams for the minute hand.
You would probably have to use hard wired electric movement rated for use with 3 or 4 foot hands, depending on what your torque requirement is. This is beyond the capabilities of the quartz movements we offer.

I want to purchase a standard c size Quartz pendulum motor, but don’t know which shaft to use. My present motor has a 3/8″ diameter shaft and 5/16″ long threaded section. I also want the gold hands 31/8″ long. Please help.

Our MVT3160 has a 5/16” threaded shaft and a 5/8” overall shaft length. My only concern is that the shaft diameter on our C cell movements is 7/16”, not 3/8: https://www.clockparts.com/standard-c-battery-size-movements/

If this would be a problem, then consider one of the AA battery movements like the MVT7160A: https://www.clockparts.com/usa-made-motors-movements/

These AA movements have a 5/16” diameter shaft.

I am trying to replace a clock movement on a very expensive boat clock. It is a Chelsea clock Newport Model (I believe). It is 2.1/8″ Square. Overall Shaft length is 7/16″ AND SHAFT LENGTH IS 3/16″. However the shaft does not have threads, but the end of the overall length has a nut and threads on the end. I have photos to help locate it.

We have a press-on at 1/4” overall shaft:
https://www.clockparts.com/american-made-press-on-movement-with-no-threaded-shaft/

The next shaft length would be 17/32”, the MVT7130A “I” shaft movement:

What are the names of the melodies for the quad chimes?

The four melodies this movement plays are 2 versions of the Westminster Chime ( 1 hour only and 1 every fifteen minutes), Ave Maria, and a strike or Bim-Bam on the half hour and hour with an hour count: https://www.clockparts.com/quad-chime-pendulum-movement-with-remote-speaker/

Inserts Fitups

I have an old wooden round mantel clock. I want to put an quartz insert into the opening. The hole diameter is 4 3/8″, the outside of the clock is 5 3/8″. Do you offer something to make this work?

https://www.clockparts.com/6-in-152mm-premium-quartz-clock-fit-ups/
These inserts are designed for a 3-1/8” mounting hole, so to properly fit you would need to make some type of adaptor ring:

I need to replace the Takane clock that was mounted in my golf cart. The back snaps into the dash and is approx. 3 5/64ths in diameter. Can you help?

Please advise what the diameter of the mounting hole size is.
It’s smaller than the diameter of the front of the clock, but actually the most important measurement.

Do you have a clock insert with a brushed gold or spun gold face with a mounting hole of about 2 1/8”, 2 ¼”, 2 3/8” ?

Our F59 series has a brushed gold roman or Arabic option.

We purchased a F108WAC 108 MM White arabic 4 1/4″ clock insert. The clock insert is just a little small and won’t stay in the clock frame. Do you have something we can use to fill the space?

Try taking the gasket off of the back of the insert clock. Wrap something like electrical or plumbers tape around the back of the insert. Then re-install the gasket.
Can be a bit of trial and error, but it normally works for small adjustments. Rubber bands can also work.

Assessories

I recently had my grandfather clock converted to a quartz movement. The pendulum set is only 16in with a small pendulum bob. It is on a AA battery by itself. Will the 25 in rod and 3in bob operate on a single AA unit?

Our AA battery powered mini pendulum movements do not have enough power to operate a 25” pendulum.
You would need to use our PD200 to operate a pendulum of this size.

I have a grandfather clock with a lyre pendulum that is operated by itself. It looks like a pd200 but Im not sure that is exactly what it is. The pendulum attachment swings perfectly until I put the pendulum on it, then it works for a few minutes and then quits. What can I do to make it swing continuously? I wasnt sure if I needed to order the PD200

The PD200 will operate a pendulum up to 7 ounces, and the PHDPD will operate a pendulum up to 10 ounces.
Make sure you know the weight of your pendulum before ordering anything.
Being level or vertically plumb is very important for any pendulum drive. It’s important that the magnet and electro magnet on any pendulum drive also be as close as possible without touching.
