D) SETTING AND READING THE AGE OF THE MOON
* The moon phase represents the age of the moon, the actual shape of the moon during
each phase is not represented.
* Use the moon phase only as a guide to the age and phase of the moon when reading
and setting watch.

Pull the crown out to the 1st position.
Turn the crown clockwise to advance the moon phase.
D-2) SETTING THE AGE OF THE MOON WITH AGE SCALE
* Check on the age of the moon for the day. Check the newspaper or other source for
the age or phase of the moon for today or tomorrow. Subtract one day before a setting
is made if the listings for tomorrow are used.
* Setting procedure(Example: age of the moon:4.4)
Pull the crown out to the 1st position.
Turn the moon disc clockwise until the center of the moon is in line with 4.4 on the scale.
D-3) SETTING THE AGE OF THE MOON WITHOUT THE AGE SCALE

Referring to section D) Reading the age of the moon , set the moon phase to the age
(0,7,15 or 22) closest to the listed.
More accurate setting can be made at the same time of the new moon (0) or full moon(15).
THE AGE OF THE MOON
The age of the moon is indicated in units of days. The average period from a new moon to
the next new moon is equivalent to about 29.5 days.
