New Quartz Chiming Movement

New Quartz Chiming Movement

New Quartz Chiming Movement. These chiming units take two C-cell batteries and have the sound options of Westminster or Ave Maria. Well made quartz movements that last for a long time, but seem to give up the ghost during daylight savings when they do die. The new base unit is 4 5/8W (117mm) x 5 1/4T (133mm) x 1 1/4D (32mm) without the hand shaft. It would require 4 3/4W (121mm) x 5 7/8T (149mm) x 1 1/2D (38mm) area to run right.

Getting to the dial and hands

There are many clock case designs and styles so this is difficult to give an exact procedure. Sometimes it is very easy to get to the dial and hands. Other times the dial has glass over it and may require you to figure out how the clock case was put together. Of course, you may have to remove some screws, or if there is a bezel the bezel tabs may need to be bent to get it to come 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.

Removing the clock hands

If there is a second hand on the clock, grab it with your fingers and pull it straight off of the clock. Hold the minute hand still as you turn the nut to the left with needle nose pliers to remove the nut and the hand. Next is the hour hand, this is only a friction fit, twist and pull off.

Removing a Hermle Quartz Movement

First thing to do when replacing a Hermle quartz clock movement is to get the old unit out of the clock case. Remove the hands and then the nut with the double slots under the hands. This nut turns to the left to unscrew, but it is not easy to do sometimes. A clock maker will have a special tool for these units only, but the customer is left to use two flat screwdrivers to do it. It is easy to slip and scratch the dial when doing this. Use a flathead screwdriver on both sides of the nut and turn them both at once to the left. The nut will come off and the movement will fall out from the back side.

Quartz movement installation

1. Place hanger on post (optional)
2. Place black washer on post (optional)
3. Put post through the clock dial face
4. Slide the brass washer onto the post of the movement that is sticking out of the clock dial face
5. Put hex nut on post and tighten to hold movement to the back of the clock face.

Quartz hands installation

1. Push hour hand onto the post as far down as it will go without touching the clock face.
2. Put the minute hand on the post
3. If using a second hand, skip to step 9 otherwise screw the cap nut on and it is done
4. If using a second hand, screw the small nut on top of minute hand then push the second hand onto the pin in the center.
5. You are done installing you're brand new quartz clock movement !

About the movement

The MSO quartz chiming movement has step motion timekeeping accuracy and includes a time setting knob on the back of the unit which is useful if the hands are not easily accessible from the front. Additionally, there is also a knob on the back to set the volume. Although this is a pendulum unit it can run with or without the pendulum. The pendulum motion does not have anything to do with the timekeeping on this unit. Another thing to keep in mind is that the clock hands are sold separately.

About the chimes

This unit will play either Westminster or Ave Maria with premium sound quality. It is quite possible this is the only quartz movement that plays Ave Maria on the market at this point. Additionally, it also has the ability to play the chime every quarter hour or only on the top of the hour. Please note that the clock chime may take an hour to correct itself, when using the hand setting knob. Of course the sound is premium as it has a larger external speaker that mounts anywhere in the clock case with just two small wood screws. The strike count at the top of the hour can be set by the button on the back of the unit. It will advance the strike count one hour each time the button is pressed. Doing this will not move the hands.

About the hands

The MSO quartz unit uses any of the low torque quartz hands that Clockworks has to offer. If replacing a Hermle quartz unit, new hands also need to be bought for your new unit as your old ones will no longer fit. It is possible to use a needle file to make the old hands fit the new unit. However it is best to just get the new hands with it just in case. This unit will take a second hand but it is optional. Clockworks offers the hands for this unit below.

About the pendulum

Overall, the pendulum that you can purchase with the movement is 16 inches. However, it has segments every inch so measure what you need, bend it and snap it off. Similarly, 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 run with or without the pendulum. If you do not need to use a pendulum then lock the pendulum swinger to one side.

About the post lengths

The movement has threads on the post and comes in two lengths. This is the fat part with the threads that takes the hex nut. The length of the threads are what we measure to get the correct post length. Do not count the part that the hands go onto in the measurement. The post lengths available for this unit is either 5/16 long or 9/16 long. The posts are all 5/16 wide, and fit into a ⅜ dial hole.
