What are the professional introductions of watches?

A watch, or wristwatch, is an instrument worn on the wrist to keep time and display the time. Watches are usually made of leather, rubber, nylon cloth, stainless steel and other materials to make a strap that binds the "watch head" that displays the time on the wrist.

The production and production of watches are based on a simple and witty invention, which is the "spring", which can tighten and store energy, and can slowly release the energy to push the running device and hands in the watch to achieve the function of displaying the time, this spring device in the watch is called the main spring.

How the watch works.

mainspring）。Watch ConstructionA watch consists of a watch head, a strap (buckle). The parts of the header include:

Movement, case, case back, mirror, literal (often said dial), hands, handle (adjust the time, also called press), order (some watch requirements).

The principle of the watch is that the watch is a precision instrument used to indicate the time, and the principle of the instrument is to use a vibration system with a constant cycle and continuous vibration as a standard. If you know the time it takes for the vibration system to complete the full vibration of a watch (vibration period) and calculate the number of vibrations, then the time elapsed after so many vibrations is equal to the vibration period multiplied by the number of vibrations. i.e. time = vibration period and number of vibrations.

The balance spring mechanical watch adopts the balance spring as the vibration system, the balance wheel 1 is fixed on the balance shaft 2, and the upper and lower journals of the balance shaft ** are in the bearing, which can rotate around the bearing. One end of the hairspring part 3 is fixed on the pendulum shaft, and the other end is fixed on the splint. Due to the elastic deformation of the hairspring, the movement of the balance wheel changes from rotation to reciprocating motion.

When the balance spring system oscillates, it is affected by the friction of the bearing, the air resistance, and the internal friction of the hairspring, and the amplitude (amplitude) of the oscillation will gradually decay until it stops. In order for it to continue to vibrate without attenuation, the balance spring system must be replenished regularly, i.e. there must be an energy source in the watch. The periodic replenishment of energy to the vibrating system is achieved by means of a special mechanism, the escapement.

The escapement is also used to calculate the number of oscillations of the balance spring system. Therefore, the balance spring system and escapement are the key devices of a mechanical watch.

What you must know about the watch is that the watch is waterproof and that there is no problem with normal wear when using the watch on a daily basis, but you should never swim with it, because the pressure is too high and the water will enter. The watch is water-resistant to 50 meters, which refers to the pressure of the water, not the depth of the water.

It is important to distinguish between them so as not to cause damage when wearing the watch into the water. Buying an automatic watch also requires manual winding, and if it is not moving for a long time, it also needs to be placed in the watch shaker to help wind it. When we buy a watch, we must not be fooled by the salesperson's water resistance of 30 meters and water resistance of 50 meters.

The watches are water-resistant, not suitable for swimming, let alone bathing. Automatic watches are not purchased once and for all, and should never be purchased for the usual reasons.

1. The waterproof function of the watch is only suitable for daily use, and does not mean that it can be taken for swimming

When we buy a watch, we always struggle with the waterproofness of the watch. Some watches are clearly water-resistant to 50 meters, so we swim with the watch and find that there is water inside. In fact, the meaning of the watch marked with a waterproof of 50 meters does not refer to the depth of the water, but to the pressure of the water of 50 meters, which must be distinguished clearly.

In everyday use, never go swimming with a waterproof watch, so as not to lose more than you gain.

Second, the automatic mechanical watch also needs to be wound manually, and if it is left unmoved for a long time, it needs to be placed in the watch shaker to help wind it

The knowledge of the watch also includes that even if the automatic watch is bought, it needs to be wound when it is left unmoved for a long time. This is because the principle of automata is determined by the swing of the human arm. If you buy an automatic watch, you need to wind it by hand every once in a while.

If you need to keep your watch for a long time, you need to put it in the watch shaker to help wind the automatic watch.

So, what else do you know to keep in mind when buying a watch?

1.The advantage of a quartz watch is that it is accurate, ** discounted. Mechanical watches, on the other hand, require painstaking manual winding, and the grid is higher than quartz.

2.It is normal for mechanical watches to have errors. 3.

The sapphire of the watch crystal is synthetic. 4.Wearing comfort is the most important thing, so be sure to wear it right away to see how it feels.

1. If you are not wearing a diver's watch, you must not take it with you. The so-called life waterproof of the dress watch can only resist the splash of rain and hand washing, and wipe dry in time when it gets wet. 2. Don't wear a mechanical watch to play mahjong, the automatic mahjong machine is a big magnetic field, wearing a mechanical watch to play mahjong iron is determined to be magnetized, once magnetized, the watch will suddenly be much faster.

If you play hand-rubbing mahjong, when I didn't say. 3. Do not wear a mechanical watch to do strenuous exercise, bumpy and strenuous exercise is naturally not suitable for precision mechanical watches. Strenuous exercise needs to depend on the time, and it is more appropriate to wear a bracelet.

When choosing a watch, you must choose some watches that can be ventilated, and you must not be too firm when wearing them, so as to ensure that there will be no problems in this state, and you can also avoid some tanning.

There are many different brands, and the production structure of each appearance is different, and the identity information brought out is also different, there are also many professional terms, and the cost of each watch is different, and so on.

A watch is a type of jewelry that people often wear. Nowadays, people generally wear watches not to see the time, but to be beautiful and fashionable, and the choice of watches must be consistent with their temperament.
