Abstract
An ornamental clock operates while submerged in a body of water, the clock having a clock face and relatively movable hands and a mechanism for moving the hands. Air bubble receivers are each mounted for movement between a first position to entrap air bubbles and a second position to release air bubbles into the water. Spaced ports deliver air into the water below each bubble receiver. Accumulation of bubbles alternately in each receiver produce buoyant forces which act through linkage to drive the clock mechanism. Apparatus is provided to deliver air alternately into the ports.
