INSTRUCTIONS
WINDING CROWN
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
Your watch is equipped with a screw-down crown
that must be completely unscrewed before you can
perform any adjustments.
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 38 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 decide
to leave your watch unworn, place the timepiece in
the case when you have adjusted the settings and
manually wound the movement. The mechanism
of the winding case will keep your watch running;
therefore all your settings will be saved. Your watch
will undergo motion and static cycles, which are
defined by our Laboratory of Movement.

SETTING THE TIME
To set the time, unscrew the crown completely,
pull it gently all the way out, and move the hands
in either direction. Once you have set the correct
time, push the crown home again and screw it down.
When you turn the hands clockwise beyond mid-
night, the calendar displays will advance as well. We
advise against turning the hands counterclockwise
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 addi-
tion to the date, day, and month, the watch also
features a leap-year display. The moon-phase dis-
play is highly accurate: it deviates from the true
lunar cycle by merely one day every 122 years. If
the watch is worn on a regular basis or placed in
a self-winding case, after the movement has been
manually wound, the perpetual calendar will keep
operating without any readjustment until February
28 , 2100. The Gregorian calendar exceptionally
th
removes February 29 on this secular year.
