2. Basic knowledge about watches
Popularization of watch knowledge: Usually the watch panel or back cover is marked QUARTZ or AUTOMATIC, so you can clearly distinguish between a quartz watch or an automatic mechanical watch.
Another way to identify is to look at the way the second hand of the watch moves. If the second hand jumps every second, then the watch is a quartz watch; conversely, if it does not jump, then It's a mechanical watch. If you find that the second hand moves for two or four seconds at a time, this is still a quartz watch. When this phenomenon occurs, it tells you that the battery of the watch in your hand needs to be replaced, because some quartz watches with better designs have this feature. The device will walk for four or five seconds at a time to notify you in advance that it is time to replace the battery.
A brief introduction to the distinction between all-steel watches and semi-steel watches: a. The coating of the all-steel watch case is bright and dark, and the edges and corners of the case are rounded and not sharp. The coating of the copper case is bright and whitish, and the edges on the back of the lugs are sharp. The ring-shaped pattern formed by the cutter can usually be clearly seen on the back of the lugs.
The textures are of different depths and sizes, and the arrangement is loose and uneven. The texture of the all-steel watch case is delicate and well-proportioned, and the arrangement is tight and neat.
b. Use a knife to gently scrape the angular part of the lug (can be inspected on the inside of the back of the lug) within a short distance. If the inside is yellow, it is a copper watch case. c. The copper watch case has poor corrosion resistance. If it is not properly maintained and used for a period of time, it is prone to fading (yellowing or redness), bubbling or peeling of the coating.
Mechanical watch: Timing instrument with mechanical vibration system, such as pendulum clock, balance clock, etc. The working principle of a mechanical watch is to use a vibration system with a constant period and continuous vibration; multiplying the vibration period by the number of vibrations is equal to the elapsed time, time = vibration period * number of vibrations.
It is generally composed of several parts such as energy, gear train, escapement, vibration system, pointer mechanism and additional mechanism. Power - spring or weight, provides the energy for the mechanical clock to work. Through the speed increase of the gear system, one winding can run continuously for many days. The escapement mechanism makes the timing frequency of the clock conform to people's concept of "seconds". The rudder or balance wheel controls the speed of the clock, and the time (marking) mechanism tells people: what time it was when the last time was sounded.
Electronic watch: The basic part is composed of electronic components. The working principle of electronic clocks is designed based on the physical phenomenon of "electricity generates magnetism and magnetism generates electricity".
That is, electrical energy is converted into magnetic energy, and then magnetic energy is converted into mechanical energy to drive the hour and minute hands to achieve the purpose of timing. Transistor balance watch: It uses dry batteries as energy source, transistors as switches, and the balance spring as the oscillation system.
Quartz watch: A quartz watch uses a "quartz crystal" as an oscillator. It uses electronic frequency division to control the operation of the motor and drive the pointer, with high accuracy.
3. Basic knowledge about watches
Watches are also called watches.
A tool worn on the wrist for timing. In social situations, wearing a watch usually means a strong sense of time and a rigorous style; people who do not wear a watch, or people who frequently ask others for the time, will always be scoffed at, because this often indicates that they have a weak sense of time. .
In formal social occasions, watches are often regarded as jewelry. For men who usually only wear rings, they are even more important. Some people even emphasized: "A watch is not only a man's jewelry, but also the most important jewelry for a man."
In Western countries, watches, pens, and lighters were once called the "three treasures" of adult men. ” is something that every man can’t live without. Like jewelry, watches worn by people in social situations often reflect their status, identity and wealth.
Therefore, the watches worn by people, especially the watches worn by men, are mostly eye-catching in interpersonal interactions. Choosing a Watch If you want to wear a watch correctly, you must first understand the watch and be good at choosing a watch.
When choosing a watch, you should often pay attention to five aspects: type, shape, color, pattern, and function. (1) Types According to different standards, watches can be divided into many different types.
In social situations, people generally distinguish types based on price. According to this standard, watches can be divided into four categories: luxury watches, high-end watches, mid-range watches, and low-end watches.
In terms of current prices, the price of a luxury watch is over 10,000 yuan, high? The price of watches is between 2,000 and 10,000 yuan, the mid-range watches are between 500 and 2,000 yuan, and the low-end watches are below 500 yuan. When choosing a specific type of watch, you must first do what you can and don’t do anything beyond your capabilities.
In addition, a series of related factors such as one's career, the occasion for appearance, the person with whom one associates, and other clothing chosen at the same time should also be taken into consideration. (2) Shape The shape of a watch is often related to its value and grade.
Watches worn on formal occasions should be solemn and conservative in appearance and avoid being weird or trendy. Men, especially distinguished men and older people, should pay more attention.
This novel and fancy watch is only suitable for girls and children. Generally speaking, perfect round, oval, square, rectangular and diamond-shaped watches have a wide range of applications due to their solemn and conservative shapes, especially suitable for wearing on formal occasions.
(3) Color selection For watches worn on formal occasions, the colors should be kept away from complexity and clutter. Generally, it is advisable to choose single-color watches or two-color watches, and watches with three or more colors should not be selected. Whether it is a single-color watch or a two-color watch, its color must be clear, noble, and elegant.
Gold watches, silver watches, and black watches, that is, watches with gold, silver, and black dials, cases, and straps, are the most ideal choices. Watches with gold cases, straps, and milky white dials can also stand the test of time and will not be out of date in any age.
(4) Except for numbers, trademarks, factory names, and brands, there is no need for other patterns that have no effect on the watch. This is especially important to keep in mind when choosing a watch for formal occasions.
If the patterns on the watch are weird and diverse, it will not only be unfavorable for use, but may also make people laugh. (5) Functional timekeeping is the most important function of the watch.
Therefore, watches used in formal occasions, whether they are pointer type, jumping type or time-telling type, should have this function, and should be accurate to hours and minutes, and even better if they can be accurate to seconds. A watch that is only accurate in time obviously does not meet the requirements.
Some additional functions, such as temperature, humidity, wind speed, direction, blood pressure, pace, etc., are optional, and none is better. In short, the functions of the watch should be few but refined, and should have practical value.
4. What are the common sense about watches?
Many situations in life may cause the glass of the watch to be damaged. Depending on the degree of damage, there may be scratches, cracks, chipped corners, or complete damage. Damage etc. If it is only scratched or cracked, you can still use it. As for the chipped corners or complete damage, the glass of the watch must be replaced. Severe damage to the glass will cause the watch to become unsealed, thus affecting its waterproof function. Judging from the material of watch glass, the plastic glass of old-fashioned watches will not explode, but mineral watch glass, especially the popular sapphire watch glass, is more likely to explode.
Some watches only support daily waterproofing, and the waterproof performance is not high. If you take these watches that only support daily waterproofing to go swimming, it is very likely that water will enter and cause fogging. In addition, the watch is produced in a dust-free environment, but there is air inside the watch, not a vacuum. That is to say, excessive temperature difference may also cause the watch to fog up. Rapid changes in the temperature of the wearing environment, based on the principle of thermal expansion and contraction, will cause the watch cover to fog up. When the temperature is high, water is in a gaseous state. When the outside temperature drops, the temperature of the glass on the watch surface is low, and the water vapor liquefies to form small water droplets.
In addition to the artificial disassembly of the back cover of the watch, there are two main reasons why the watch gets dust. First, you should first check whether your watch cover is tight, whether there are cracks due to aging or whether the whole watch case (ring) is loose. Because the watch is not well sealed, water usually gets into it when it gets dust. The second reason is caused by internal wear, because the dust on the dial does not come from the outside.
When performing maintenance on the movement watch. The requirements for the sealing of the watch case are very high. If your watch is not waterproof, impurities such as dust and water vapor can easily get inside the movement. When you find that there is fog on the watch mirror, you must remove the water vapor in time. , usually it needs maintenance once every two years! For watches with extremely strong waterproof performance, maintenance usually lasts for about 3 years. Quartz movement watches also need maintenance. It is best to replace the battery 3 to 4 times.
The reason why the mechanical watch does not run is because the battery is dead: The most common reason why the Tissot quartz watch does not run is because the battery is dead. Solution: Replace the battery with a new one. Insufficient power: Some friends do not wear watches every day, or wear them for a short time every day, which results in insufficient power of the automatic mechanical watch and the watch does not run. Automatic mechanical watches are wound by arm movement. If the amount of exercise is not enough or the watch is not worn, the watch will not run. This principle applies to automatic mechanical watches of various brands. The solution: wear it more, exercise more, and remember to wind it when not wearing it.

Some additional functions, such as temperature, humidity, wind speed, direction, blood pressure, pace, etc., are optional, and none is better. In short, the functions of the watch should be few but refined, and should have practical value.
7. For general knowledge about watches, please come in
Today’s watches are basically mechanical watches. Ordinary mechanical watches only have the measurement of hours, minutes and seconds as their basic functions. The structure of the prime mover system is composed of original parts such as barrel wheels, barrel shafts, and springs. It is the energy part of the watch, supplements the resistance consumption of the entire mechanism, promotes the rotation of each gear, and maintains the oscillation of the balance wheel; the transmission system consists of It is composed of a center wheel, a guide wheel, a second wheel, an escape wheel, etc. It is a set of transmission gears that transmit the engine power to the escape wheel and drive the pointer mechanism. ; The escapement speed regulation system consists of two parts: the escapement mechanism and the speed regulation mechanism. The speed regulating mechanism relies on the periodic oscillation of the balance spring to maintain accurate and regular continuous movement of the escapement mechanism, thereby achieving the speed regulating effect.
In addition, there are automatic watches. Automatic watches are based on ordinary mechanical watches and add a part of automatic mechanism devices to automatically wind up the clockwork through the arm movement of the wearer in daily life. "AUTOMATIC" is printed on the dial, indicating an automatic watch. In the automatic mechanism, the weight (automatic pendulum) swings, and the special function of automatic winding is realized through the connection between the automatic winding gear train and the prime mover train. Around 1920 in England, watchmaker John Howard invented and manufactured the prototype of the modern automatic watch, which laid the foundation for the development of the automatic watch industry. But he was not the first person to make automatic watches. As early as 1770, a Swiss, Louis Burler, produced the earliest automatic watch. Because it is handmade, the quantity is very small, and it is difficult to see it in the flea market. Because it is the predecessor and birthplace of modern automatic watches. As a result, the Swiss watchmaking industry has become famous. The driving part of the automatic watch, the self-weight hammer (i.e. the automatic oscillating weight), is a self-winding transmission system through a set of automatic gear trains, and is automatically wound by arm swings. In the early automatic watches, automatic weights were also produced that made linear reciprocating motion in two grooves on the watch center. This automatic mechanism was called a bucket automatic; it was eliminated early due to its poor winding effect. But because of its limited production, it is very valuable for collection. Some automatic watches have a pointer on the dial that displays the amount of automatic winding, which can determine the reliability of the automatic winding. Due to the complexity of the mechanism, which requires 14 parts, there are not many automatic watches using this type of mechanism.
8. Basic knowledge about watches: What are the watch straps?
(1) Precious metal strap: expensive, meticulous in workmanship, and very luxurious. Suitable for high-end watches and jewelry watches, etc., worn on special occasions.
(2) Steel chain watch strap: moderate price, complete range of high and low-end products. Its advantages are durability, boldness and sportiness. The main disadvantages are that some skins can cause allergies, the strap is difficult to clean, and it can easily trap dirt and evil.
(3) Genuine leather watch straps: There are many types and the price difference is also very different. There are crocodile skin, lizard skin, ostrich skin, cowhide, sheepskin, etc. Newer leather straps include: devil skin, water snake skin. An elegant watch must be paired with a top-grade leather strap to show its overall elegance. Comfortable to wear is its advantage. The main disadvantages are that they are susceptible to moisture, difficult to maintain, and not durable.
(4) Canvas or nylon watch strap: cheap, mainly used for military watches and sports watches. It absorbs water and easily produces odor.
(5) Plastic watch strap: The cheapest, mainly used with electronic fashion watches. The pattern design is diverse and colorful, but it has a feeling that it has not yet grown up.
(6) Silicone rubber strap: Gradually favored by watch manufacturers. It is mainly used on waterproof and diving watches, and its application will become more and more widespread in the future. Silicone rubber has excellent physical properties: non-toxic, resistant to high and low temperatures, acid and alkali resistant, elastic, and easy to maintain.
