What is the principle of the eco-drive table in the watch? Put it on your hand and the watch will go?

In fact, the eco-driven watch in the watch is a fully automatic watch. Its working principle is to add a set of automatic winding mechanism to the movement of ordinary mechanical watches. Usually equipped with an eccentric hammer that can rotate around the center of the watch.

In daily life, with the help of the wearer's arm movement, the weight swings back and forth around the shaft under the action of inertial force and static moment, and is transmitted to the lever shaft through the reduction gear train, thus automatically winding.

As long as it is worn on the hand for a certain period of time every day, the automatic winding mechanism can automatically wind up the spring, so that the automatic watch is always in a full load state, and a stable power is maintained to drive the watch machine, ensuring that the watch has high travel accuracy and works continuously.

Extended data:

Some automatic mechanical watches are manually wound, while others are not. Generally, it can run continuously for about 30 hours when the spring is full, depending on the movement. Old people, people who often sit in offices and people who seldom exercise are the least suitable for wearing such watches. In this case, it is recommended that the wearer wind the watch manually at regular intervals.

Room temperature automatic mechanical watch, 24 hours error of 45 seconds is normal error. Because the automatic mechanical watch must be automatically wound by the swing of the arm, it must be worn for more than eight hours every day to ensure accurate timing.

In the process of use, the automatic mechanical watch can keep a certain tension all the time, so it can keep walking for more than 24 hours after being removed from the wrist.
