About Tide Timers

 

Our Story

 In 1971, Lou Schelling and Andrew Marvel invented the first Tide Clock by meeting with a leading clockmaker and having them make a clock movement that works on Lunar/moon time. So instead of a regular clock movement rotating twice in 24 hours, a tide movement would rotate twice in 24 hours and 50-1/2 minutes because the moon passes overhead on the average of 24 hours and 50-1/2 minutes and the magnetic pull of the moon controls the tides.

Since 1971, the Tide Timer has been the world’s biggest selling tide clock with over 400,000 sold. We are proud that our Tide Timers are made and assembled here in the USA. If for any reason you are not happy with it, you can return it to us for a full refund. Also note that our tide indicator hand is exposed. Kids and grandkids tend to want to pull them off so if you ever need new hands for the life of the clock, just email us at info@tideclocks.com and we send you a new one for no charge.

Tide Timers are easier to understand and more readily accessible than printed tide tables. The red ball hand always shows how many hours until your next high or low tide because the Tide Timer runs on moon time, where each day has 24 hours and 50 1/2 minutes. Especially along the East Coast of the United States and Canada, the tidal cycles are regular and rhythmic with two high and two low tides during each lunar day.

Tide Timers are assembled in the USA by hand using the most accurate battery-operated quartz movements. We offer no-hassle purchase satisfaction.  All clocks are backed by our 1 Year Free Repair/Replacement Guarantee. After 1 year, we can replace your movement for $32 for the lifetime of your clock. 

Tide Timers are recommended for use on both Coasts of the United States and Canada.  On the Atlantic they never need adjustment.  On the Pacific, including Hawaii, they can be calibrated to different coastal locations using our proprietary setting tables.  See the NOAA chart in the Where Tide Clocks Work section for many other areas around the world where tide clocks are effective.  Tide clocks will not work in the Gulf of Mexico.
