Removing a Bad Unit

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.

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 Movement Assembly

These are the assembly instructions for the time only quartz clock movement into the clock case.

  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 – 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.
  6. 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.
  7. Put the minute hand on the post
  8. 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.
  9. 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 !
How to measure quartz clock movement post

When replacing, 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.
