According to the different types of watches, the mainstream watches on the market can be divided into the following two types:
1. Mechanical watch: a clock adjusted by a mechanical ** device.
2. Quartz watch: a watch adjusted by an electronic device - a quartz device.
Mechanical watches can be divided into two types: manual mechanical watches and automatic watches
1. Manual mechanical watch: using manual winding movement, by turning the watch head for the main spring of the movement to full winding, when the spring is completely exhausted, push the gear to run, push the pointer to go.
2. Automatic watch: The automatic movement relies on the weight of the oscillating weight in the movement, but the swing of the arm wearing the watch will drive the rotor to rotate, and at the same time drive the main spring in the watch to wind the watch and push the time.

That's the advertising effect, that's what was said upstairs.
There are also 2:50's.
Mechanically, however, if an hour runs out of power, it is most likely to stop the second or minute hand at around 45 minutes (not necessarily).Because this position is the place where the twist caused by the needle of the table overcoming the earth's gravity is the largest.

Mechanical watches are not intended to be as precise as quartz and electronic watches.
Wearing a mechanical watch is wearing jewelry. Wear toys.
In pursuit of precision, wear an electronic stopwatch.
It doesn't matter if you figure it out. Hehe.
In addition, some mechanical watches have a stop second function, that is, the second hand does not move when adjusting the time, and the next time the landlord pays attention to the purchase of a watch with a stop second function, hehe.

Manual mechanical watch, hand winding movement, by turning the handle of the watch, the main spring in the watch movement is fully wound, through the mainspring completely exhausted to push the gear to run, pushing the hands to keep time.
When the arm wearing the watch swings, it will drive the rotor to rotate, and at the same time drive the mainspring in the watch to wind the watch and push the time.
Mechanical watches are generally divided into two types: hand-wound and automatic. The power of a mechanical watch** is the mainspring of the movement, which drives the gears and then the hands.

In daily life, some friends have a hobby of collecting things. For example, girls like to collect designer bags, and boys like to collect all kinds of models and watches. Among them, watches mainly include mechanical watches, electronic watches, quartz watches, light-wave watches, diver's watches, transistor balance watches, etc.
What is a mechanical watch.
A mechanical watch is a watch that generates power through mechanical movement to make the watch hands move. Mechanical watches can generally be divided into the following two types: manual and self-winding.
The power of these two machines** is powered by the mainspring in the movement, which drives the gears and then pushes the watch hands, but the power ** is different. Hand-wound mechanical watches rely on manual winding for power, and the thickness of the movement is thinner than that of ordinary self-winding watches, so the weight of the watch is relatively light.
A self-winding watch uses the automatic rotating disc of the movement to oscillate left and right to generate power to drive the mainspring, but the thickness of a hand-wound watch is relatively smaller than that of an automatic winding watch.
Mechanical watches do not need to be replaced, and can be used for a long time with regular maintenance and oil washing. Mechanical watches are larger than quartz watches, and errors can occur due to the quality of the production and the susceptibility of the movement inside the watch to the influence of gravity.
When wearing a watch, the sweat on your hands is corrosive to the case, and the case should be wiped frequently with a soft cloth. When not wearing the watch, the plastic holder should be inserted. When sleeping, do not wear a watch, especially a luminous watch, which has a certain amount of radium radiation, and must be taken off before going to bed.
Omega watches are one of the most counterfeited Swiss watches, and the highest level of counterfeiting of all the watches I've seen. Is there an easy way to distinguish an authentic Omega watch? >>>More
The most important thing for a watch to be waterproof is the sealing ring, or O-ream, or I-ream, which is made of rubber, nylon or Teflon, which forms a waterproof seal on the glass, the rim, the case back and the joint between the jaw and the case. The degree of sealing is the waterproof level, and the common marks are: 30m, 50m, 100m, 200m, etc. >>>More
Mechanical watches are driven by machinery, and the designers set the monthly calendar to 31 days when designing, which is to simplify the internal structure of mechanical watches and avoid overly complicated designs. Therefore, regardless of the number of days in the month, the calendar display of a mechanical watch will be set to 31 days per month. >>>More

The difference between four-axis and six-axis manipulators: four-axis manipulators and six-axis articulated manipulators. The four-axis robot is specially designed for high-speed pick-and-place operations, while the six-axis robot provides greater flexibility in production movements. Four-axis manipulator small assembly manipulator, "four-axis manipulator" refers to the "selective assembly joint robot arm", that is, the arm part of the four-axis manipulator can move freely in a geometric plane. >>>More
