Why won’t the hands of my clock go round when I can hear a regular ticking sound from the mechanism?
It’s a large quartz wall clock with a conventional quartz unit on the back connected via a hole in the clock-face to the hour and minute hand. The clock is ticking regularly, but the hands just don’t move, even with a new AA battery.
The hands on these clocks are splined. In other words, they have indentions in the hole in the arm that correspond with ridges on the pin that actually turns them. This clock has been dropped or bumped hard enough that the hands have slipped far enough off the pin to keep them from being turned.
