![]() Actual high tide occurs somewhat later, due to factors such as viscosity, friction, and underwater topography. Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about six hours later. 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 the 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 black bar on the watch’s tide graph indicates the current tide. Since this performs calculations using integer values only (no fractions), the margin for error of the displayed Moon age is ☒ days. The actual Moon age average cycle is 29.53 days, but this can vary anywhere from –1 day to +1 day for specific months. This watch perform a rough calculation of the current Moon age starting from day 0 of the moon age cycle. * The angle to the Moon in relation to the direction at which the Sun is visible from the Earth. The greater the angular distance between the Moon and the Sun,* the more we see illuminated. The Moon goes through a regular 29.53-day cycle during which it appears to wax and wane due to how the Sun illuminates the Moon and the relative positioning of the Earth, Moon, and Sun. ![]() The left-right orientation of the Moon phase is reversed when viewing from the Southern Hemisphere or from a point near the equator.Note that at times the image shown by the Moon phase indicator may differ from that of the actual Moon in your area. ![]() The Moon phase indicator shows the Moon as viewed at noon from a position in the Northern Hemisphere looking south.The light part of the Moon phase indicator shows the part of the Moon that is visible in the sky during each particular phase.The Moon phase indicator of this watch indicates the current phase of the Moon as shown below. ![]()
