Description of what it means to require drilling of the clock dial. Clock dials often only have the center hole for the clock hand post to come through. If using a spring driven mechanical clock movement, holes would need to be drilled. This is so the clock key will have access through the dial to wind the clock. This hole is typically 3/8 of an inch wide.

What is a time track

A time track is that outer ring that runs around the Roman numerals. The mechanical clock hands and also the battery run clock hands are based on this measurement.

Paper dial information

The paper dials on this page come square but have a round time track. Spray glue can be used to stick the paper stock dial onto a thin board for a dial. If the dial is to be round instead of square it will require cutting into shape.

Round clock dial information

The round metal dials may come with a protective plastic coating that is removed by the customer, it is hard to tell it is there sometimes but if the dial has scratches, it most likely has this coating that needs to be removed for the finished clock project.
