This watch has automatic self-winding and manual winding.
Although this is a self winding watch, the kinetic energy provided by the movement of the hand is not enough to support the continuous operation of the watch.Therefore, manual winding is required to ensure that the watch provides the correct time.
Please wind the mechanical watch by turning the crown clockwise for 15 to 20 complete revolutions every day. Over 20 times may do harm to the watch mechanism.
