People who wear watches know that mechanical watches are semi-automatic and fully automatic mechanical watches, so how should they be distinguished? How to distinguish between mechanical watches? I’ll tell you about it below.
An ordinary mechanical watch is what is called a manually wound watch, which has a manually wound handle inside. A fully automatic mechanical watch replaces the manual handle inside the mechanical watch with a rotatable weight that surrounds the winding gear. When the watch wearer’s hand is in motion, the hammer moves in a small circular motion, driving the winding gears to achieve the full winding effect. When the winding is full, the hammer is still moving, but the gears are idling and will no longer be wound.In fact, semi-automatic mechanical watches and automatic mechanical watches are both automatic mechanical watches, but the only difference between the two is that the former is a single-phase watch, while the latter is a two-way watch with a hammer. The difference between the two is that the former is a single-phase watch, while the latter is a two-way watch. Other than that, there is little difference. But a fully automatic mechanical watch does not use a battery, but has a winding, and the only difference with ordinary mechanical watches is that there is no manual winding handle in a fully automatic mechanical watch, but a rotatable hammer around the winding gear in the watch, when the human hand is in motion, the hammer does a small circular motion, driving the winding gear, winding up the clockwork. When the clockwork is tightened to a certain level, the hammer is still moving, but the gears are idling and no longer winding the clockwork. The power comes mainly from the wrist activity of the wearer, and the flying tourbillon of the watch oscillates when the owner is active, thus winding the watch. Therefore, when the wearer is not active at all or does not wear it for a long time, the string force will be insufficient or empty, causing the watch to go out of time or stop. Older people and those who sit in office with little movement are not suitable to wear such watches. In this case, it is recommended that the wearer should wind the watch manually on a regular basis. Because automatic mechanical watches must be wound automatically by the swing of the arm, they must be worn for more than eight hours a day to ensure accurate timing. Luxury,
