How to read the moon phase indicator
The moon phase shows us the number of days since a new moon. This indication is
shown between “0” and “29.5” (the number of days it takes for the moon to complete
its cycle).
The moon phase indication on this watch should be used as an approximate
representation only. It is not intended to provide an exact depiction of the moon as it
appears in the sky.
The indication of “5” shown in the illustration above represents 5 days since the “new”
moon.
• Refer to page 8for instructions on setting the moon phase indicator.
