How to Choose the Right Clock Mechanism

Measure the thickness of your clock face before selecting a mechanism. Choose a threaded shaft long enough to pass through the clock-face material and still accommodate the washers and securing nut. The overall shaft length is not the same as the maximum clock-face thickness.

Clock mechanism Shaft length Thread length Recommended maximum face thickness
13 mm mechanism (02CM1) 13 mm 5 mm 3 mm
17 mm mechanism (02CM17) 17 mm 9 mm 7 mm
23 mm mechanism (02CM23) 23 mm 15 mm 13 mm

Tip: If your clock-face material is close to the maximum thickness, check that the securing nut can be fully fitted before assembly. Allow at least 2 mm of thread for the washers and nut, as indicated in the specifications.

Please specify your preferred set of hands in the notes section at checkout.
