Automatic mechanical watch internal structure

Mechanical watches can usually be divided into the following two types: hand chain and automatic winding watch (AUTOMATIC). The power source of these two machines is powered by the spring in the movement, which drives the gears and pushes the hands. The way of power source is different. The mechanical watch that is wound on the hand is powered by hand. The thickness of the movement is thinner than that of the automatic spring winding. The weight of the watch is relatively light. The self-winding watch uses the movement of the automatic rotating disc of the movement to generate power to drive the spring, but the thickness of the watch is relatively larger than that of the clockwork.
