SET TING THE CALENDAR
Pull the crown out to position 1. In this position, you can use the direct-advance function to move the
calendar forwards one step at a time by turning the crown slowly to the right. The calendar must not
be adjusted between 10 p.m. and 2 a.m. The leap year display has four positions: "1", "2", "3" and "L".
"L" stands for "leap year". If the current year is a leap year (i.e. the year is divisible by 4 – e.g. 2016,
2020), you must adjust the calendar so that the leap year display shows "L". "1" corresponds to the
first year after a leap year, "2" to the second and "3" to the third. Once set correctly, the perpetual
calendar will automatically show the correct date at all times. You do not need to do anything until
1 March 2100 when you must manually move the calendar forwards by 1 day. Although 2100 is divisible
by 4, it is not a leap year according to the Gregorian calendar.
Warning:
In order to protect the watch from the ingress of water, the crown must always be in position X (screwed
in) and should only be pulled out to position 1 or 2 when setting the watch.

READING THE TIME IN THE DARK
Both the dial and the hour and minute hands of your watch have luminescent elements that allow you
to read the time effortlessly, even in total darkness.
READING THE CHRONOGR APH
Chronograph seconds hand: The scale for the central chronograph seconds hand runs around the
edge of the dial.
Minute and hour counters: The subdial at 12 o'clock has two hands, which run continuously and
show the elapsed time on a 12-hour and a 60-minute scale. The hour and minute counters can be
read like a standard analogue time display. In other words, one revolution of the minute counter is
equal to 60 minutes, and one revolution of the hour counter is equal to 12 hours.
