Quick-setting the calendar
18 | 19
Pull out the crown to position 1. In this position, you can use the rapid-
advance function to move the calendar forward a step at a time by turning
the crown slowly in a clockwise direction. The calendar must not be adjusted
between 8 pm and 2 am.
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. 2012, 2016, etc.), you must adjust the calendar so that the leap year dis-
play 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 need do nothing
until 1 March 2100, when you must manually move the calendar forward by
one day. Although 2100 is divisible by 4, it is not a leap year according to the
Gregorian calendar.
Please note:
You must not move the calendar forward beyond the correct date. The compli-
cated movement is mechanically programmed and cannot be moved back in
time without adjustment to the movement. However, if you do move the date
forward beyond the correct date, you have two options: You can either pull out
the crown to position 2 to stop the movement until the calendar setting once
again matches the correct date. This makes sense if the date has been set
only a few days ahead. Or you can slowly advance the calendar by four years
until you reach the correct date. Alternatively, you can entrust this operation
to your watchmaker.
