Abstract: A clock is provided having a visual effect mechanism associated with the shaft of the clock that would ordinarily drive the second hand. The visual effect produced is that of the earth rotating about a central sun every sixty seconds while clouds drift past the apparently stationary land masses of earth. The mechanism utilizes a depiction of the earth attached by a holding bolt or post to a second hand or equivalent structure, and a transparent overlay disposed over the depiction of earth and pivotably supported by the holding bolt or post.

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.

Abstract: A novelty clock is provided wherein a spherical representation of the earth rotates about the face of the clock as would a second hand. 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.
