About automatic mechanical watches The automatic mechanical watch is composed of about 140 or more parts, which can work together to display the time. So automatic watches don't run on batteries. The automatic movement marks the passage of time through a series of gear mechanisms and is wound by wrist movement when wearing. Also known as automatic winding, the watch uses an automatic movement to use kinetic energy and arm swing to provide energy for the vibrating rotor to maintain the ticking sound of the watch Because engineering art is integrated into hundreds of parts that constitute the movement, they are considered to make watching collectors more satisfied.
