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.
