Rotary Pendulum Drive, battery operated
We sell two different rotary drive units so please read the description carefully. The rotary pendulum drive mechanism supports and drives a 2 3/4" diameter rotary gold finished pendulum from the bottom. This mechanism can be combined with almost any quartz movement to create an anniversary or novelty clock of your own design. Uses one "AA" battery. The movement housing is 2.3" x 2.17" and .72" thick. The pin is centered left to right but not the other direction: it is .80" from one end and 1.50" from the other.
