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).

To set your watch correctly, proceed as follows:
– Release the crown by turning it to the left.
– Wind the movement (approximately 20 revolutions of the
crown).
– 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.
– Turn the minute hand and the 24-hour hand forwards until they
indicate the desired time. The 24-hour hand should be set to
show the correct time of the chosen time zone. 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 and,
in doing so, the seconds hand.
