To get anything for a clock movement from Clockworks we first need to identify the mechanical clock movement. This is done by decoding the identification markings on the back plate of the movement itself. By knowing what the movement is, it can be replaced with a new mechanical clock movement.
How do I choose the right clock movements for my project?
You’ll want to make sure that the clock movements thread length is long enough to fit through the thickness of the material you are mounting the movement to (clock dial material could be a simple clock face or decorative items like a wood plaque).
How do I choose the right size clock hands?
Choose clock hands based on the size of your clock dial you are working with. In Figure 3 this clock is a 24" clock and the designer chose 10" Clock Hands - generally, you want your clock hands to sit somewhere between the inside and outside edge of your numbers or numerals. So a little less than half the diameter of your clock face is standard.

You’ll want to make sure there is enough room underneath the glass to fit the total shaft length including its minute hand cap nut or if you’re adding a second hand. The post mounting hole of your clock dial (or mounting material) needs to have a large enough diameter to fit the shaft of the clock movement through it.
How do you identify a clock movement?
The numbers or symbols on the movement help identify the manufacturer. For example, one of the most common movement manufacturers is Hermle, also known by Welby, Buliva and Talley Industries. Movements made by Hermle have six or seven numbers with a dash in the middle and list the pendulum length if the clock has one.

How to measure shaft length on clock?
The easiest and most accurate way to measure the shaft length on a clock movement is to use the depth gauge on a digital caliper . A ruler can also be used to measure the shaft length, if you do use a ruler to measure the shaft size make sure the ruler starts at 0, many rulers have their zero point a bit away from the end of the ruler.
How much length should a post come out of a clock?
The threaded portion of the shaft (post) should come out of the mounting surface with about an 1/8” of length left for the mounting hardware. (Note: Some push on style clock movements will not have a threaded shaft.)
How to use glass front on clock?
When using a glass front on your clock keep in mind the total shaft length (total post length). You’ll want to make sure there is enough room underneath the glass to fit the total shaft length including its minute hand cap nut or if you’re adding a second hand.
