ABSTRACT:
A tide clock employs a tide dial and a solar time dial which are rotatably driven at different uniform rates by a timepiece. The time of the next high or low tide is indicated by alignment of selected indicia on the dials. A graphical indication of the current status of the tidal stage is also continuously represented on the clock. The clock may also be employed to readily determine the approximate time of the high tide for up to fourteen succeeding days.
