Selecting the Right Replacement Clock Movement

A. Thread length: 5 mm (13/64 inch) B. Total shaft length: 18 mm (45/64 inch)

Measure the thread shaft of your old clock mechanism. If the length is shorter than or equal to 5 mm, then this clock movement mechanism is suitable for your clock. We offer four different shaft length movements:

18 mm (45/64 inch), 18.5 mm (23/32 inch), 23 mm (29/32 inch), and 28 mm (1-3/32 inch).

If you need to replace your old movement, carefully measure the movement shaft length. If you're still unsure which one is right for you, please refer to the pictures, take a photo of the shaft part and hands size, and we will help you confirm the correct fit.
