ABSTRACT:
A novelty clock is provided wherein a spherical representation of the earth revolves about a stationary depiction of the sun at the face of the clock as would a second hand. While revolving about the sun, the earth also rotates upon its own axis which is angularly disposed to the straight line between sun and earth. The earth's motion, in conjunction with depictions of other planets of the solar system, provides an appealing and realistic visual effect. The motion of the earth is achieved by a mechanism driven by rotation of the shaft which would otherwise drive the second hand of the clock.
