There are three main differences:

The power sources of automatic mechanical watches and manual mechanical watches are different

The power source of automatic mechanical watches is vibration. When a watch is worn on the hand, it is inevitable to be vibrated when the person moves the watch. There is a structure on the watch that collects and converts vibration energy into mechanical rotation energy. If the spring of the watch is not tightened when worn on the hand, it will automatically tighten the spring when it is vibrated. If you put the watch in a place without vibration, it will stop moving within 24 hours.

The power source of a manual mechanical watch is the "spring". So it needs to be wound frequently. This is mainly because the spring inside the movement needs to be tightened again after it is released, and it will turn to the crown of the watch. When winding the spring, you will hear a "la la" sound. Generally, a manual mechanical watch needs to be wound up once every 24 hours.

The thickness of automatic mechanical watches and manual mechanical watches is different

Automatic mechanical watches use the power generated by the left and right swing of the automatic disk at the bottom of the movement to drive the spring to generate energy, but the thickness of the watch itself is relatively thicker than that of ordinary manual spring watches. Mechanical watches do not have this component, so they appear thinner!

The movement structure of automatic mechanical watches and manual mechanical watches is different

The internal movement parts of automatic mechanical watches are all composed of mechanical parts, and they are balance spring watches powered by springs.

The movement of mechanical watches includes transmission system, prime mover system, winding and hand-setting system, escapement and speed regulation system, and pointer system. The movement parts are combined by splints and screws.

Which is better, an automatic mechanical watch or a manual mechanical watch?

These two mechanical watches have their own advantages and disadvantages. Automatic mechanical watches do not need to be wound manually, but rely on the swing of the arm to provide power to the movement. Therefore, it must be worn for more than eight hours a day to ensure accurate timekeeping. Therefore, automatic mechanical watches are not suitable for people who exercise less, such as people working in offices or the elderly. Such people are more suitable for manual mechanical watches.
