Fans of stars have specific names. What are the names of Nana Ou-yang fans?

When the temperature of electronic watch is 25 ~ 28℃, the time error of one day and night is less than one second, and when the temperature is below 0℃ or above 50℃, it is two seconds slower every day and night. At the same time, when the temperature is as high as 60℃, the LCD panel will turn black, and when the temperature drops below 0℃, the LCD panel will lose its display function. Therefore, in winter, the electronic watch can only be worn on the wrist, relying on the constant temperature of the human body to maintain its normal timing.

In addition, too high and too low temperature will also cause battery leakage and movement corrosion. The battery of an electronic watch can generally be used for more than one year, but the lighting lamp consumes a lot of power, and the power consumption for one second is equivalent to more than one hour. When the battery is almost dead, the light will dim, or the digital display will dim or even disappear when it is turned on.

When replacing the battery, if you don't know the watch maintenance technology, you should send it to the watch repair shop for installation. Moreover, the battery specifications are not standardized, and there are many batteries of various brands, which cannot be used at will.

Attention should be paid to the electronic watch: do not press the button too hard to avoid failure; The LCD panel needs to be replaced after five to seven years of use; If the battery is dead, take it out in time to prevent the liquid from corroding the movement. When it is found that the light is not on, the button fails, and there is a big error in timing suddenly, it should be repaired in time. It may be that the solder joints of components are in poor contact or fall off. Electronic watches, especially digital electronic watches, are generally poor in waterproof performance.

Although some instructions or back covers are printed with the word "waterproof", try to avoid contact with water. The structure of electronic watches is different from that of mechanical watches. They are all electronic circuits and electronic components. If they enter the water, it will be "catastrophic" and the whole watch will be scrapped. In particular, LCD panels and integrated circuits are not only afraid of water, but also affected by tides and will fail over time.

So you'd better take off your watch when washing your face and clothes. When it rains, you should prevent the rain from splashing. If water is found in the electronic watch, or water vapor accumulates on the inner wall of the watch cover, it should be immediately sent to the watch repair shop for dehumidification.

1, to prevent contact with moisture and moisture, and to avoid discoloration and deformation of the belt.

2, to prevent exposure to the sun for a long time, so as not to fade the belt.

3, because the cortex is easy to penetrate, it is necessary to prevent contact with oily things or cosmetics.

The gold-plated layer on gold-plated watches is mostly 14K gold, which contains 58.5% pure gold and a certain amount of silver. After silver reacts with some volatile industrial waste gas in the air, a black silver sulfide film will be formed on the surface, which will make the gold-plated watch lose its golden luster.

Therefore, wear gold-plated watches to avoid contact with chemicals and waste gas, such as gas, liquefied gas, sulfur soap, etc., and always keep them dry and clean. It is best to wipe it with a flannel once a week. In addition, chloride in sweat is very corrosive to gold-plated watches. When the gold-plated watch is stained with sweat, it should be wiped clean in time to avoid the original luster of the watch being eroded by sweat.

The yellow coating of a watch is a metal film composed of copper, zinc and aluminum alloy. If it is not well maintained, it will easily fade and lose its luster. Before wearing a gold-plated watch, wipe the case with a clean soft cloth and evenly coat it with a layer of colorless nail polish. Dry it before wearing it, and then apply it every 1 ~ 2 months/time.

After this treatment, not only can the color of the yellow-plated watch not be worn, but also the brightness of its appearance can be increased, and at the same time, sweat and moisture can be prevented from damaging the watch in hot summer.

① Avoid strong impact: Although the watch has shockproof function, it should still avoid sudden impact, so it is best to take off the watch when doing exercise.

② Keep away from magnetic objects: Watch parts are made of metal. Although there is an anti-magnetic device, it is easy to make the time inaccurate when encountering magnetic objects, so it is best to put it next to radios, televisions and other electrical appliances.

③ Don't wash quartz watches: Waterproofing is generally life waterproofing, which can only prevent occasional hand washing, rain splashing, bathing and swimming!

The most common situations of mechanical watch maintenance are water ingress and collision. Unless the mechanical watch is marked with waterproof function, water in the case must be avoided, because water will cause mechanical corrosion and be very destructive. The sea is untouchable. Even if the waterproof meter is marked, it can only be guaranteed for one year, because the waterproof ring of the meter will be tired after a whole year of wear and tear, plus various inevitable external factors such as sweat and dust, so a new waterproof ring must be replaced after one year, otherwise it will not have waterproof function.

In addition to waterproof, but also to prevent collision. Within the scope of economic ability, we might as well have two or three watches to replace them in daily life: wear a mechanical watch when doing static activities and a sports watch when doing sports, which will help to extend the service life of watches according to local conditions.

Mechanical watches are driven by mechanical gears and clockwork, and there will inevitably be friction when they rotate, so it needs long-term lubrication to reduce the wear rate of parts. Otherwise, wait until something goes wrong before sending it for repair. Often, the problem is already very serious. It's best to go back to your mother's house once a year to check if there is any improper use and water.

Especially in Taiwan Province province, the climate is hot and humid, and sweat, rain and dirty air have accumulated for many years, which has caused chronic erosion to machinery. The frequency and degree of damage are much higher than those in Europe, America and Japan, so "regular inspection" is very important; Then it needs to be thoroughly cleaned and maintained every three years.

The safest maintenance and repair are handled by orthodox institutions, which is safer. The internal cleaning must be handed over to a professional master, while the external cleaning work, the mechanical watch owner may wish to do it himself; Brush the strap with a soft brush dipped in cleaning liquid, and then rinse it with clean water. Waterproof watchcases can also be cleaned in this way; Never brush a waterproof case.

It is very important to clean the outside every day because of sweat, dirt, dust, etc. Even though they are imperceptible, they are actually accumulating. If not cleaned, the strap will rust, rot or become brittle. Therefore, the owner had better clean it often.

dress etiquette

If you want to wear a watch correctly, you must first understand the watch and be good at choosing it. When choosing a watch, we should always pay attention to its type, shape, color, pattern, function and material.

(1) species

A. Classification by price

According to different standards, watches can be divided into many different types. In social situations, people generally distinguish their categories according to their prices. According to this standard, watches can be divided into four categories: luxury watches, high-end watches, mid-range watches and low-end watches. At present, the price of luxury watches is above 1 10,000 yuan, high-grade watches are between 2000- 1 10,000 yuan, middle-grade watches are between 500-2000 yuan, and low-grade watches are below 500 yuan.

When choosing a specific type of watch, you should first do what you can, and don't do anything beyond your ability. In addition, we should also consider a series of related factors such as personal occupation, appearance occasion, communication object and the clothes we choose at the same time.

B. Classification by style

According to the different styles of watches, watches can also be divided into fashion watches (such as Longines), fashion watches (such as Armani), leisure watches (such as Tissot), sports watches (such as Casio) and business watches (such as Neon).

2) shape

The appearance of a watch is often related to its value and grade. Watches worn on formal occasions should be solemn and conservative, and should not be unfamiliar or fashionable. Men, especially venerable people and the elderly, should pay more attention. Novel and chic watches are only suitable for girls and children.

Generally speaking, round, oval, square, rectangular and diamond watches are widely used, especially for formal occasions.

(3) Color

Choose a watch to wear on formal occasions, and its color stress circle is complicated and messy. Generally, you should choose a monochrome watch or a two-color watch, and don't choose a watch with three colors or more. Whether it is a monochrome watch or a two-color watch, its color should be clear, noble and elegant.

Gold watch, silver watch and black watch, that is, watches with gold, silver and black dial, case and strap, are the most ideal choices. Watches with golden case, strap and milky white dial can stand the test of time and will not be out of date in any era.

(4) mode

Except for numbers, trademarks, factory names and brands, there is no need for other useless patterns to appear on the watch. It is especially important to keep this in mind when choosing a watch on formal occasions. If the patterns on the watch are strange and varied, it is not only not conducive to use, but may make people laugh.

(5) Function

Timing is the main function of a watch. Therefore, watches used in formal occasions, whether they are pointer-type, word-skipping or time-telling, should have this function, and they should be accurate to time and minutes, preferably to seconds. Only the watches that were allowed at that time obviously did not meet the requirements.

Some additional functions, such as temperature, humidity, wind speed, direction, blood pressure, pace, etc. , are dispensable, it is better to do nothing. In a word, the functions of watches should be few and precise, and they should be of practical value.

(6) Materials

The existing watchcase materials include alloy, steel, ceramics and silicone. Generally, the price of alloy watches is below that of 300 yuan, while the price of steel watches is above 1000 yuan (for example, Tissot watches are mainly steel watches). According to different ceramic materials, the price of ceramic watches ranges from 500 to 2000 yuan, while the price of watches with silicone case is mostly below 1000 yuan.
