IWC Schaffhausen BIG PILOT'S WATCH PERPETUAL CALENDAR Mode D'emploi page 25

— 2 5 —
Important: The watch is water-resistant in positions 0, 1 and 2 as long as the crown is not moved.
The crown should generally always be screwed in for normal use to ensure the stability of the seal
and to protect the winding mechanism.
WINDING POSITION
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 recommended to wind the
watch by turning the crown through approximately 20 revolutions as this will ensure maximum preci-
sion. The crown must always be in position X when you are wearing your watch.
SET TING THE CALENDAR
Release the screw-in crown and pull it out to position 1. You can now set the date by turning the crown
to the left (direct advance). You should not use the rapid-advance function between 8 p.m. and
2 a.m. because the movement automatically advances the date during this period.
