I bought the mechanism for a tidal clock. Basically a regular clock, but instead of showing the hours it will indicate the time it takes to reach high tide and low tide. We love visiting the La Laja beach with low tide, so this is a perfect ‘thing’ to place on the wall. I only bought the mechanism, so I will need to make the entire clock myself. I could have bought a finished product directly, but I did not like the versions that were available. I thought I could do better myself.

A tide clock is specifically designed to track the motion of the tides, which are influenced by the Moon’s position relative to the Earth. A tide clock typically completes one cycle every 12 hours and 25 minutes, reflecting the average time between two high tides or two low tides.

• Get the tide mechanism. Note that there is only one dial! There is only one dial needed to indicate the water is going up or going down. There is no need for a dial indicating minutes or seconds.
• Get a regular clock. Try and find a cheap one where you can more or less easily disconnect the plastic front panel, and disconnect the clock mechanism.
• Dismantle the regular clock. Remove the mechanism and remove the backplate. We only need the outside frame and the plastic front cover.
• Create a new backplate, and put it in the clock. The backplate has the term ‘High tide’ on top. Then to the right a countdown to low tide. 5, 4, 3, 2, 1. At the bottom we have the text ‘Low tide’ and on the left of the backplate we have a countdown to high tide from the bottom to the top. 5, 4, 3, 2, 1.
• Place the tide mechanism in the clock, and the tide clock is finished!
