TIDE & TIME CLOCKS
This page features tide and time clocks restored and redesigned by Gary J. Penta. Each clock has been cleaned, inspected, and repaired to good working order. After restoration the clocks were 'upscaled' with a unique rustic or vintage design. No two are the same. These are not antiques, but restored modern timepieces that have been given a second life. Check back as new clocks are added often.

What exactly is a Tide Clock?
'A tide clock is a specially designed clock that keeps track of the Moon's apparent motion around the Earth. This special clock is divided into two 6 hour and 12.5 minute tidal periods that show the average length of time between high and low tides in a semi-diurnal tide region, such as most areas of the Atlantic Ocean.

Parts of a Tide Clock
The bottom of the tide clock dial (6 o'clock position) is marked "low tide" and the top of the tide clock dial (12 o'clock position) is marked "high tide." The left side of the dial is marked "hours until high tide" and has a count-down of hours from 5 to 1. There is one hand on the clock face, and along the left side it points to the number of hours "until" the (lunar) high tide. The right hand side of the clock is marked "hours until low tide" and has a count-down of hours from 5 to 1. The number pointed to by the hand gives the time "until" the next low tide.

What does it do?
Tide clocks count down the number of hours from high or low tide, as in "one hour past high or low tide". When the clock reaches the half way point ("half-tide"), it then counts the hours up to high tide or low tide, as in "one hour until high or low tide". An adjustment knob on the back on the instrument may be used to set the tide using official tide tables for a specific location at either high or low tide.

Where does it work?
Analog tide clocks are most accurate for use on the Atlantic coasts of America and Europe. This is because along the Atlantic coastline the moon controls the tides predictably, ebbing and flowing on a regular (12- to 13-hour) schedule. However, in other parts of the world such as along the Pacific Coast, tides can be irregular. The Pacific Ocean is so vast that the moon cannot control the entire ocean at once. The result is that parts of the Pacific Coast can have three low tides a day. Similarly, there are areas in the world like the Gulf of Mexico that have only one high tide a day.'
