How To Determine Which Movement You Need- Press Fit, Euro Shaft or High Torque
In order to find a correct replacement, you will first need to gather a few measurements and information from your current movement. A model number alone does not provide enough information to replace a movement- you will also need to determine the following:
1. Type of movement/hands you are replacing (press fit, euro shaft or high torque)
Your current minute hand will be able to easily indicate what type of movement you have. Simply examine the hole in your minute hand.
- If it is round or has a hexagonal looking eyelet, and if the hand pushes onto the shaft then your movement is a press fit movement
- If the hole has two straight sides and a rounded top and bottom, then your movement is a euro shaft movement
- If your minute hand is over 160mm in length then we strongly recommend that you use a high torque movement
Please note, your minute hand hole should be visible. If there is anything protruding from your original minute hand then you may have removed the minute shaft with the hand by accident. To separate this shaft from the minute hand you will need to unscrew the hand nut on the front of the hand.
2. Hand Hole Dimensions (Shaft Diameter Of Hands)
As the shaft diameter for all hands varies significantly, your original hands may not be compatible with the replacement movement that you select. It is important that you measure the hand hole dimensions to confirm whether it is a match. If not, you can order replacement hands that will be compatible with your replacement movement. In addition, the total length of the hands are measured from the centre of the hole to the tip, not from end to end.
3. Total Shaft Length Of Your Current Movement
Measure the total shaft length of your old movement by measuring from the face of the movement to the very end of the shaft. This measurement is the entire shaft length when the movement has been removed from the clock. It is important to get accurate measurements especially if your clock had a lens. We also recommend measuring your dial thickness to ensure the replacement movement will be a suitable fit.
4. Follow Our Guide
For more detailed information on how to get these measurements, we have created an easy to follow guide (with pictures) and an additional video link which you can view here: Step-By-Step DIY Clock Movement Replacement Guide
Please note, it is very important that you have gathered this information correctly prior to purchasing. Additional information that you will need to obtain includes your dial thickness and dial hole diameter from your current clock.
What Is The Difference Between A Standard Press Fit and A German Press Fit Movement?
The main difference between a standard press fit movement and a German press fit movement comes from the hand hole dimensions which have slightly different measurements. It is important to measure your existing hand hole dimensions prior to purchasing, to ensure the movement will be a suitable replacement. In addition, the finished appearance between the two movements differs slightly- a German press fit movement uses a collar to secure the movement to a clock (which requires a slightly larger dial hole and thickness), whilst a standard press fit movement instead uses a hex nut and a brass thread.
