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.
Winding: turn the crown forwards until it stops (DO NOT OVERWIND).
Note: do not wind the watch more often than is necessary. For a watch that is
worn all the time, a single winding each day will ensure that it functions correctly.
2. Time setting: hours – minutes – seconds. Pull the crown out to position 2. Turn
the crown forwards or backwards. Synchronise the seconds by pushing the crown
back to position 1 to coincide with a given time signal.
Note: The calibre does not have a 'stop second' mechanism. To synchronise, the
crown should be gently turned backwards and pressure maintained to stop the
seconds hand. Release when the display corresponds to the timing signal and
push crown back to position 1.
