The Perfect Part DIY Universal Mechanical Movement Kit 55x55x16mm 31mm Shaft Black

DIY Quartz Clock Movement Kit

This DIY kit provides a quartz clock movement with mechanical hands for wall-clock repair or custom builds. It suits hobbyists and repairers who want a universal drop-in mechanism and are comfortable assembling loose components. The package includes the movement, hands and hardware in an unassorted pack ready for installation.

Shaft Fit and Dial Thickness

The movement fits a 55 mm by 55 mm host cutout with a 16 mm case depth. A total shaft length of 31 mm and a usable thread length of 24 mm limit the maximum dial thickness to about 24 mm. Builders needing a longer shaft for thick dials or a shorter shaft for thin panels should look at other movements.

31 mm Total Shaft Length

The single specification that decides compatibility is the 31 mm total shaft length paired with 24 mm of usable thread. Measure your dial thickness and mounting surface before ordering; if the dial exceeds the thread allowance the hands will not secure properly.
