While rotating about the face of the clock, the earth also rotates upon its own axis, thereby providing a more realistic and appealing visual effect. The special motion of the earth is achieved by a motion producing mechanism driven by the rotational force of the shaft which ordinarily drives the second hand of the clock. | |
