3-position crown
Adjusting the time and stop seconds
Pull the crown right out to position 3. The seconds
hand will now stop. Adjust the time by turning the
crown in either direction. When the crown is turned
the 24-hour disc also turns. Synchronise your watch
with a time signal (telephone, radio, TV) and then push
the crown back in to position 1.
Adjusting the time zone and the date
Pull the crown out to the intermediate position 2. Turn
the crown forwards or backwards to adjust the hour
hand in the corresponding direction by successive
jumps of one hour, which will not affect the minute or
seconds hands.
When the hour hand passes midnight, the date will
change automatically, indicating either the next day or
the day before, depending on the direction you turn the
crown. It is necessary to adjust the date at the end of
each month with less than 31 days. Push the crown
back in to position 1.
