Mechanical automatic watch’s feature: Automatic watches are made up of about 130 or more parts that work together to tell time, very complex construction. Automatic movements mark the passage of time by a series of gear mechanisms, and are wound by the movement of your wrist as you wear it. The first winding and enough wind is important for the mechanical watch.. What can I do when the watch stop? Wind the crown 20-30 times clockwise to start the watch and give it some reserve power If you do not wear an automatic watch consistently (for about 8 to 12 hours a day), you can keep the watch powered with a watch winder.
