This beautifully detailed clock with a brushed silver face and highly polished solid brass case with Atlantic Coast Tide Hand. A single AA battery powers the precision movement for two years or more. Locally manufactured with great care and pride, making this Cape Codder clock one of kind! 6" diameter dial in a deep, solid brass case. Tide Hand works only on the Atlantic Coast and provides Tide mark indication. Made in the USA Tide clocks can be used wherever there are semidiurnal tides. On the Atlantic Coast of the United States and Canada the tide clocks seldom need adjustment. On the Pacific side of North America, including Hawaii, they can be calibrated to different coastal locations with special setting tables but they must be reset once a week on Saturdays to be accurate. This is because the Pacific tides are mixed semi-diurnal south of Alaska’s Yakulat region all the way to Central America. Tide clocks will not work in the Gulf of Mexico. |
