The mechanism that turns the hands on the cenotaph clock tower is seen in this picture.

The motor that turns the hands on the face of the clock is nothing more than a tiny wall clock motor. On the upper left hand side of the picture can be seen that motor. The hands were originally turned by a very heavy pendulum powered by two car batteries. I bypassed the pendulum with a tiny one RPM synchronous clock motor. The motor is powered by the regular 110 volt AC lines and directly turns a worm gear which is greatly geared down so very little power is needed to turn the hands.
