shown below.

Moon Phase
Moon phase (part you can see)(part you cannot see)
• The Moon phase indicator shows the Moon as viewed at noon from a position in the
Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
• The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon
appears to wax and wane as the relative positioning of the Earth, Moon, and Sun
changes. The greater the angular distance between the Moon and the Sun,* the more
we see illuminated.
*
The angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
This watch performs a rough calculation of the current Moon age starting from day 0
of the moon age cycle. Since this watch performs calculations using integer values
only (no fractions), the margin for error of the displayed Moon age is
±1 day.
