what's the difference between automatic mechanical watch and mechanical watch

Mechanical watches are also divided into fully automatic mechanical watches, semi-automatic mechanical watches and ordinary mechanical watches. Did you know?

First, they are constructed differently

A fully automatic mechanical watch, as the name implies, is fully automatic. It is certain that a mechanical watch does not need your battery, but a fully automatic mechanical watch does not require manual winding. It only needs to be worn for more than 8 hours a day to maintain normal use throughout the day.

The oscillating weight rotates in two directions, counterclockwise and clockwise. If only one direction can be wound, it is called a semi-automatic mechanical watch. If it can be wound in both directions, it is a real automatic mechanical watch, and this is the "perpetual motion machine" that men dream of.

The mechanical watch needs to be manually wound to maintain the mechanical movement inside the watch.

The thickness of the movement of the ordinary mechanical watch is thinner than that of the ordinary self-winding watch, and the weight of the watch is relatively light. The automatic mechanical watch uses the automatic rotating disc of the movement to swing left and right to generate power to drive the mainspring, but relatively speaking, the thickness of the watch is larger than that of the hand-wound watch.

Some fully automatic mechanical watches have manual winding, some do not, but there are still the best manual winding. Generally, it can run continuously for about 30 hours when the mainspring is full, depending on the movement.

Second, they work differently

If the automatic mechanical watch is not worn by the person, it will stop, and the running time is also completely stopped. Therefore, an automatic mechanical watch must be worn for at least eight hours a day to ensure its normal operation. As long as the mechanical watch is fully wound, whether it is worn or not, it will keep going. This is a big difference between the two watches.

Third, they also affect quality differently when not in use

If the automatic mechanical watch is not worn frequently, it will have an impact on the quality of the watch. Therefore, many people who buy this type of watch will use the watch winder to maintain the quality of the watch if they are not wearing it. If the mechanical watch is not placed for a period of time, it will not affect the quality of the watch. This is a detail that people who buy automatic mechanical watches need to pay attention to.
