TIME SETTING
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 move-
ment as the seconds hand passes 60. Now move the minute
hand a few minute strokes beyond the time to be set. Then posi-
tion 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
forwards by 12 hours.
Important: Although the watch is water-resistant in positions 0,
1 and 2, the crown should always be screwed in again for normal
use (position X).
