PERPETUAL CALENDAR
The perpetual calendar indicates the day of the
week, the date, and the month, automatically tak-
ing into account months with 28, 29, 30, and 31
days. It switches directly from September 30 to
October 1 or from February 28 to March 1. In leap
years, it also displays February 29 and then jumps
directly to March 1 at midnight. In addition to the
date, day, and month, the watch also features a
leap-year display. The moon-phase display is highly
accurate: it deviates from the true lunar cycle by
merely one day every 122 years.
If the watch is wound daily, the perpetual calen-
dar will not require any manual corrections before
February 28, 2100; this is a secular year that by
exception omits the 29th of February.
Note:
The date change mechanism is engaged between 8
p.m. and 2 a.m., and the moon-phase changer between 5:30
p.m. and 6:30 p.m. Within these time windows, please do
not perform any calendar or moon-phase adjustments. To
make sure your corrections do not interfere with any switch-
ing actions, set the watch to 7 a.m. and observe the color of
the day/night indicator.
Should your watch have stopped running, please
wind it before you make any settings or corrections.
To actuate the correction push pieces, use only the
stylus that was delivered with your watch. The use
of other tools could damage your timepiece.
Use the stylus to press the push piece all the way
in and then carefully release it again.
