Anniversary / Rotary Clock Movement – Battery Powered Pendulum Drive

This anniversary / rotary clock movement is a pendulum-only, battery-powered drive unit designed for use in modern anniversary (400-day style) clocks. It is used exclusively to make the four-ball pendulum rotate back and forth, creating the classic visual motion found in newer anniversary clocks. This unit does not keep time and is not a timekeeping movement. It is intended only to drive the rotating pendulum assembly. The movement operates on a single AA battery (not included) and includes a four-ball pendulum assembly as shown. The shaft is center-mounted, making it compatible with many modern anniversary clock designs that use a separate timekeeping movement or quartz time display.
