First, determine the status of the year in the leap-year cycle (leap
year or the 1
st
, 2
nd
or 3
rd
year). Use the stylus provided in the
presentation case to press the pushpiece set into the crown of the
watch. This advances the months as well as the year indicator when
the months pass December. If necessary, press the pushpiece until
the year indicator changes to the correct year in the leap-year cycle:
B (leap year/bissextile), 1, 2 or 3. Then continue to press the push-
piece until the right month appears.
The calendar is now set to indicate February 29 every leap year.
Caution!
If you go too far and pass the desired month, you will have
to press the push-piece up to 47 times to advance through the
four-year cycle to the right month and year.

First, consult a calendar or almanac to determine the number of
days since the last full moon. Using the stylus provided in the
presentation case, press on the push-piece as indicated to advance
the moon until it appears full in its aperture. Continue to press the
pushpiece once for each day since the last full moon in the calendar.
Your watch is now set to show the changing phases of the real moon.
Leap years: Every four years, an extra day (February 29) is added to the year to make
up for the fact that the annual orbit of the earth (the tropical year) takes about 365 ¼
days. Leap years, with 366 days, are generally divisible by four. Thus 2008, 2012, 2016,
2020, etc. are leap years.
