Connecticut River Marble Tide Clock

Crafted in Rhode Island from beautiful, imported, natural marble, this tide clock features a map of the Connecticut River.  Tide clocks do not show the time of day, but rather the time remaining until low tide or high tide. Please note: tide clocks will not be accurate everywhere. Tide clocks are based on semidurnal tides. Your clock will come with detailed instructions on how to set the clock for an accurate reading of the tides in your area.

8" marble tile equipped with a AA-battery operated mechanism. Battery not included.
