Our tide clock is one of the most unusual tide clocks yet! It is a Shark? Or is it..? The falling tide holds a surprise for our patient fisherman. A precision tide movement is combined with a whimsical moving display that reflects your actual tide conditions. If you are a lover of the sea this tide clock is one you must have for that special place in your home, office or beach house. Each clock is made by hand, housed in a hardwood case and measures 11" x 6" x 2½" deep. Please note; this clock is calibrated for use only on the East coast of North America.
