Abstract
A trick action type clock, wherein a dial plate which is arranged in front of ornaments is made of left and right side dial plates mating along a line passing through a center of rotation of the hands. A planetary gear mechanism actuates the left and right side dial plates so as to make them rotate and revolve around the center of rotation of the hands to produce an opening and closing motion. Therefore, the dial plate made of the two mating parts performs an opening and closing motion which produces a strong impression due to the surprising dynamic change.
