SETTING THE TIME
To set the time, gently pull the crown all the way
out and move the hands in either direction. Once
you have set the correct time, push the crown home
again. The day/night indicator allows you to verify
whether the time displayed by your watch is between
6 a.m. and 6 p.m. (white) or between 6 p.m. and 6 a.m.
(blue). When you turn the hands clockwise beyond
midnight, the calendar displays will advance as
well. We advise against turning the hands coun-
terclockwise across midnight because this would
desynchronize the calendar displays; however, it
would not damage the calendar mechanism.
PERPETUAL CALENDAR
The perpetual calendar indicates the day of the
week, the date, and the month, automatically taking
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 calendar will not require any man-
ual corrections before February 28, 2100; this is a
secular year that by exception omits February 29.
WINDING CROWN
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
WINDING
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal mass
in motion; this tensions the mainspring, which stores
the energy. When you take off your fully wound
watch, it will continue to run for at least 35 hours.
When it has stopped after depleting the power
reserve, it can be rewound by hand (about 10 clock-
wise turns of the crown).
Your complicated self-winding wristwatch was pre-
sented to you in a case with a winder. If you do not
intend to wear your watch for a longer period of
time, please return it to the case where the constant
motion of the winder will keep it wound. By using
the winder, you can eliminate the need to reset the
calendar when you put on your watch again.
