Synchronised to the moon's daily cycle, the tide clock gives you an innovative and convenient guide to tides. Simply set the hand to the full tide position at exactly high tide for your chosen location, then throw away your tide table! The quartz driven hand will rotate every 12 hours and 25 minutes around the solid stainless steel fascia, giving you the state of the tide at a glance. This design also provides an indication of how many hours remain until high or low water.Designed to complement most homes the tide clocks simple, clean, quality appearance appeals to all tide time users not just one specific sport or pastime.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.(NOTE: There are other influences on sea levels that effect exact tide times and the user should take these into account. Strong on / off shore winds, changing volume of river flows, atmospheric pressure, the suns own gravitational pull, when lined up with the moon.)195mm in diameter, wall mounted.
