1. Normal position (wearing position): when pushed
into the case, the crown ensures that the watch is

Occasional winding: if the watch has not been worn
for 44 hours or more, wind it up with the crown in
position 1.

Date setting: pull the crown out to position 2, turn the
crown backwards and push it back to position 1.

and 2am.
3. Time setting: hours – minutes – seconds. Pull the
crown out to position 3. The seconds hand will stop.
Turn the crown forwards or backwards. Synchronise
the seconds by pushing the crown back to position 1
to coincide with a given time signal.
