Quartz Clock Second Hands
Quartz Clock Second Hands come with a mounting post that is a tube sticking out of the bottom. This tube is what sticking into the top of the hand shaft post on the quartz clock movement. It is only a friction fit, press the tube in and its all installed. If by chance it is not climbing the hill from 6 o'clock to 12 o'clock, it may require tightening for a better fit. This is not the usual situation, but it does happen. To tighten the post for a tighter friction fit is easy because the tube that mounts the hand is split, so just squeeze slightly with some needle nose pliers and it will be tight again. Remount the hand as before and it should climb the hill no problem.
There are two types of quartz movements that run these hands. Step motion is a movement that the second hand jumps from one second to the next. Sweep motion, this is when it sweeps around with no stopping right around the dial.
