WATCH FUNCTIONS
The crown has 2 positions:
1. Normal position (wearing position): when the crown is positioned against the
case, the crown ensures that the watch is water-resistant.
Occasional winding: if the watch has not been worn for 45 hours or more, wind it
up with the crown in position 1.
2. Time setting: hours – minutes – seconds. Pull the crown out to position 2. 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.
Correcting the date: press the corrector (C) positioned at 10 o’clock.
