Setting your watch correctly
To set your watch correctly, proceed as follows:
• Wind the movement (approximately 20 revolutions of the crown).
• Pull out the crown to position 2 and turn the hands forwards to approxi-
mately 4.40 a.m. This ensures that the calendar mechanism is not in the
middle of the automatic switching phase and that you can also see the
calendar displays easily.
• Push the crown to position 0 and pull it back to position 1.
• Slowly turn the crown to the left. The calendar now advances in steps. Set
the display to yesterday's date, keeping an eye on the month and the year.
• 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 sec-
onds hand passes 60.
• Turn the hands forwards until the date display changes to today's date.
The hands will now be positioned between 12 midnight and 1 a.m.
• Now turn the hands forwards to the current time. If you are setting the
watch in the afternoon, you must turn the hands past 12 (noon) again. Now
move the minute hand a few minute strokes beyond the time to be set.
Then position the minute hand by moving it gently backwards until it is
exactly above the correct minute stroke. This ensures that the minute
hand begins to move immediately when you restart the movement.
• Push the crown back to position 0 to start the movement.
The entire calendar is now automatically set correctly. There is no need for you
to know the current phase of the moon or whether you are in a leap year. You
do not even need to set the day of the week. This simplified setting is very con-
venient, particularly if you have not worn your IWC watch for a few days.
