How does a Maratime tide clock work?
Tides are caused mainly by the moons gravitational pull on the ocean. The time it takes the moon to reappear at the same place in the sky each day is 24 hours and 50 minutes. Most areas in the world have two high tides and two low tides a day, so the tide clock has been specially designed to rotate twice each lunar day (every 12 hours and 25 minutes) giving you a quick and easy indication of high and low water. The quartz tide clock will always stay synchronized with the moon.
