How To Troubleshoot Your Tide Clock

Staying in Tune with the Sea

A tide clock is a wonderful way to stay in tune with the rhythm of the sea. Metcheck's collection includes the elegant, handcrafted Maximum Harbormaster Tide Clock, and the practical and weather-resistant ClimeMET Tide Clock. Both are designed to keep track of the lunar cycle and show you when high and low tides are due. Like any timepiece, they may need a little adjustment. If your tide clock isn't showing accurate readings, there are a few simple troubleshooting steps you can follow. 

Troubleshooting ClimeMET Tide Clock

Using the ClimeMET Tide Clock is simple and easy. One of the most common issues that owners have is that the tide clock hand stops moving. When experiencing this, first try replacing the AA battery with a new one. Then check that the hand is not catching on the dial or the glass because even a small amount of misalignment can prevent the hand from turning. Similarly, if the tide readings appear to be wrong, just reset the hand to the next high tide at your closest coastal location using a local tide table. For a full walkthrough, see our detailed guide on setting up your tide clock. After that, keep an eye on it over time for any minor adjustments, especially in estuaries, because of natural lunar progression. To ensure long-lasting performance, remember to keep your clock in a sheltered position, gently clean the dial face, and replace the battery every year so you can continue to enjoy reliable and accurate tidal tracking.

Troubleshooting Maximum

Similar to the ClimeMET dial, it is very easy to determine if your Maximum Harbormaster Tide Clock is functioning properly. First make sure it has a fresh battery. Then, simply time it against a regular clock. It takes 12 hours for a regular clock to make one complete revolution. However, a tide clock requires 12 hours and 25 minutes to make one complete revolution. If the hand on your Harbormaster completes one revolution in 12 hours and 25 minutes then it is working properly. 

Caring for Your Tide Clock

By caring for your tide clock, you keep it working at its best. Always mount a tide clock using the brackets on the back of the clock, and in a location suitable to its design. For example, the ClimeMET CM4305 is weatherproof and designed for sheltered outdoor spaces, whereas the Maximum Harbormaster, is made of polished brass and should be used as an indoor statement piece. Whatever tide clock you own, use good quality batteries and replace them every year. This is an easy thing to do that will reduce the risk of the tide clock being inaccurate for a long time! Checking the clock regularly against local tide tables and making any small adjustments as needed will keep your tide clock reliable for many years to come.
