Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about six hours later. The greater the error in a particular Moon age, the greater the error in the resulting tide graph. Remember that the margin for error of the Moon age displayed by this watch is ☑ day. The tide graph displayed by this watch is based on the current Moon age.The lunitidal interval differs according to your current location, so you must specify a lunitidal interval in order to obtain the correct tide graph readings.

The tide graph of this watch indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal interval. Tides rise and fall about every six hours. Tides are the periodic rise and fall of the water of oceans, seas, bays, and other bodies of water caused mainly by the gravitational interactions between the Earth, Moon and Sun. The current tide level is indicated by the displayed graphic segment. The Tide Graph has six graphic segments, each of which indicates a different tide level.
