Functions of the crown
X = Normal position
0 = Manual winding position
1 = Date adjustment
2 = Setting the time
1. Manual Winding: if the watch has not been worn for a long period
of time, wind the movement before setting the time. Unscrew the
crown counterclockwise to position [0], then turn the crown clockwise
20 to 30 times.
2. Time Setting: to set the time, unscrew the crown counterclockwise
to position [0] and pull out to position [2]. Push the crown back into
position [X] when the correct time is reached. When setting the time,
please ensure that the date display is also set correctly. It should
advance at midnight. If it advances at noon, you will need to turn the
hands forward 12 hours.
3. Date Setting: after months with less than 31 days, you need to
set the date to the first day of the next month. To do so, unscrew the
crown counterclockwise to position [0] and pull it out to position [1].

Turn the crown to set the date. On watches with Day function, turn
the crown in the opposite direction of the date adjustment to set the
Day. To prevent damage to the date-switching mechanism, we
advise not to manually reset the date between 8Pm and 2am.
4. Always remember to screw down the crown clockwise after
adjustment, to ensure water resistance and prevent possible damage
to the movement.
Remarks:
Automatic watches acquire their energy from an oscillating weight
that is activated in response to the movements of your wrist.
Depending on the model, the power reserve ranges from 38 to 48
hours. Manual winding is only necessary if the watch has not been
worn for a long period of time, or if it has stopped.
Depending on the type of movement, the accuracy of a mechanical
movement may vary one to two minutes per week. Accuracy is
strongly influenced by the way the watch is worn.
