Abstract
A tide circle is provided as one form of tide indicator which rotates about a pivot point which is spaced from a center of the tide circle. An hour hand also pivots about this pivot point. The tide circle and hour hand are geared together so that the tide circle moves slower than the hour hand an amount correlating with tide change. The tide circle includes high and low tide indicators thereon which align with the hour hand at high or low tide. A window in the hour hand can be provided as a tide scale which aligns with these indicators at high and low tide. A portion of the tide circle within the window indicates whether the tide is increasing or decreasing and current tide magnitude. A face of the clock includes markings and indicia to facilitate reading of time with the hour hand.
