correcting the moon phase
The moon-phase display can be advanced in steps
of 24 hours by pressing the correction push piece
at 4 o’clock all the way in.
Begin by advancing the lunar disc until the full
moon is displayed in the aperture. Now, determine
the date of the last full moon using the “Full Moon
and Leap Year Calendar” brochure or an almanac.
To correctly set the moon phase, press the cor-
rector all the way in as many times as days have
elapsed since the last full moon.
The exact moon phase for a given date can also be
