Automatic watch


Automatic mechanical watches can usually be divided into the following two types: manual winding and automatic winding watches (AUTOMATIC). The power source of these two machines is powered by the spring in the movement, which drives the gears and then pushes the hands, but the power source is different. Manually wound mechanical watches rely on manually twisting the mainspring for power. The thickness of the movement is thinner than that of the general self-winding watch, and the weight of the watch is relatively light. The automatic winding 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 manual winding watch is smaller than that of the automatic winding watch.

The characteristic of mechanical watches is that they can be used for a long time through regular maintenance and oil washing without changing the battery.

It is larger than a quartz watch, and errors occur due to the quality of the production and the movement inside the watch is susceptible to the influence of gravity. Usually mechanical watches are calculated by the number of seconds of daily error, while those of quartz watches are calculated by the number of seconds of monthly error.
