<Procedure for Setting the Moon Phase>
• The moon phase indicator shows the phases of the moon, and is not intended to depict
the actual shape of the moon. Use it as a reference for the moon phase.
1. Pull the crown out to the first click position (date adjustment position).
2. Adjust to the current moon phase by turning the crown
counter-clockwise
. (Turning
the crown clockwise adjusts the date.)
• Check the moon phase
for that day in the
newspaper or other
source, and then adjust
the moon mark by
referring to “Viewing
the Moon Phase” on the
next page.

[Helpful Hint for Accurately Setting the Moon Phase]
A more accurate adjustment can be made by setting at times of a new moon (the moon
mark is not visible: Day 0) or full moon (moon is at the 12:00 position: Day 15).
