Clock Insert and Movement Sizing Guide

Industry standard for clock INSERTS/MOVEMENTS is the outside dimension of the bezel/rim of clock face.

To select the right size REPLACEMENT insert:

  1. Measure the size of the hole if inside of a thicker material. Such as a Waterford or Tiffany clock replacement or inserted in thick wood.
  2. To order the appropriate insert, look in the item descriptions for the HOLE SIZE and ensure that it is equal to or slightly less than the size you have.
  3. The FACE or dimension of the outer bezel is always larger than the mounting hole size. THIS IS HOW INSERTS ARE CATEGORIZED.
  4. In some instances you may need to ensure the hole size is appropriate size and outer bezel measurement will fit within clocks design (i.e. not covering applied images or carvings).

If you are looking for clock MOVEMENTS, these are commonly mounted on the backside of thinner materials (plywood) and the shaft is inserted from the backside through a hole just large enough but not too large to ensure the washer and nut will cover hole and hold movement in place.

The most relevant measurement for MOVEMENTS is the shaft length.

The shaft length is measured from the plastic housing to the very tip of the shaft. NOT the length of the threads.

The shaft length ordered should be longer than the material mounted to.

EXAMPLE: 1 1/4” movement fits 3/4” material (plywood).
