It winds electrically every hour operating on a 3 volt direct current. It has a mechanism which can set the clock on the hour if it receives an electrical impulse from a remote master clock. It has electrical contacts to control two types of slave clocks. One set of contacts closes 2 times per minute to operate wall slave dials.

Slave clocks were designed to operate on 24 volt direct current. One mechanical digital display mechanism is included. The pendulum is not original. The wiring within the case is not original. Some of the electrical contacts require restoration. The clock movement itself is in excellent condition. SIZE: The wooden case measures 21 inches X 21 inches by 7 inches deep.
