Time setting
Pull the crown out to position 2. This will stop the move-
ment. To set the time accurately to the second, it is best
to stop the movement as the seconds hand reaches 60.
Now move the minute hand a few minutes beyond the
time to which you wish to set the watch. 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. To start the seconds hand,
push in the crown to position 0. When setting the time,
please be aware of the date change, which always takes
place at 12 midnight. If this change has already taken
place at 12 noon, you must move the hands forward by
12 hours.
Setting your watch correctly
To set your watch correctly, proceed as follows:
• Release the crown by turning it to the left.
• Wind the movement until it is fully wound (about
40 revolutions of the crown).
• Pull the crown out to position 1.
• Turn the crown to the right to advance the date display
a day at a time. Set the display to yesterday's date.
