With the crown in the winding position (0), you can also wind the
automatic movement by hand. A few revolutions of the crown are
enough to start the movement. However, it is better to wind the
watch by turning the crown through approximately 20 revolutions
as this will ensure maximum accuracy.

Release the screw­in crown and pull it out to position 1. In this
position, you can use the direct­advance 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
8 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. if the year is divisible by 4, e.g. 2016, 2020, etc.),
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
need do nothing until 1 March 2100, when you must manually
move the calendar forwards by one day. Although 2100 is divis­
ible by 4, it is not a leap year according to the Gregorian calendar.
