IWC Schaffhausen BIG PILOT’S WATCH PERPETUAL CALENDAR Instrucciones De Operación página 14

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.

Please note:
– If the crown is turned too quickly, the display discs might not be positioned correctly in the display
window. Generally, such a default is automatically corrected by the movement when the calendar
advances within the following 24 hours. Should this not be the case, the movement needs to be
reset by an IWC watchmaker.
– You must not move the calendar beyond the correct date. The complicated movement is mechanic-
ally programmed and cannot be moved back in time without making a professional adjustment to
the movement. However, if you do move the date forwards 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 matches the correct date once again – this makes sense if the date has been set only a few
days ahead – or, you take your watch to your watchmaker, who will be able to adjust the movement
to reset the calendar. This is recommended in the event of larger maladjustments.
TIME SET TING
Pull out the crown to position 2. This will stop the movement. To set the time accurately to the second,
it is best to stop the movement as the seconds hand passes 60. Now move the minute hand a few
minute strokes beyond the time to be set. Then position the minute hand by moving it gently back-
wards until it is exactly above the correct minute stroke. This ensures that the minute hand begins to
