How much do you know about the watch three defense?

Every man should have at least one watch that can withstand exercises, and the watch which is resistant to exercise is definitely good in three aspects. The most typical example is Rolex, which can be said to be one of the best brands of three defense. However, we often hear the watch three guards, then about the watch three defense, how much do you know?

First of all, we need to know what the three guards refer to. Watch three refers to watch waterproof, antimagnetic and shockproof performance. It belongs to the quality index of the watch. Waterproof, antimagnetic and shockproof performance test, the main test is the external environment in order to watch machine defense common factors (moisture, magnetic field and impact) ability to influence. The reason why we need to carry out three proofing tests is that the external environmental factors such as water vapor, magnetic field and impact may cause damage to the parts of watches, thus affecting the accuracy of watches and even stopping the watch. We have a look at the three defense of the watch.

waterproof

The first is waterproof watch watch three, in modern society, waterproof should be one of the most important subject in three, because we live in the boiling water, if the watch is not waterproof, it can be very convenient, can wash hands to watch to take it down. Moreover, when water vapor, dust and chemical corrosive gases are contacted with the core, they will corrode due to fouling and lead to volatilization of lubricating oil, which will affect the travel time and long-term stability. Therefore, watches must have some waterproof properties. In fact, most modern watches can do this, and those watches that are completely waterproof are basically art treasures specially designed for collection, and do not need to be worn.

But this is not to say that we can sleep well in the waterproof watch of the wrist watch, because the waterproof also has different grades. It is possible, for example, 30 meters, 50 meters, 100 meters, or even 1000 meters. In general, if only for living water (wash face, wash hands, etc.), 30 or 50 meters of waterproof is enough. But if you want to swim or dive, the watch is at least 100 meters above the wrist watch. In addition, I would like to advise you that, if possible, the higher the waterproof performance is, the better the waterproof performance watch is, and for example, the diving table. Of course, waterproofing is only one of the factors that you buy, and it doesn't need to pursue high waterproofing, otherwise the fun of playing watch must be lost.

Antimagnetic

When the watch is placed in the external magnetic field, the time and speed of the watch will change or even stop because of the influence of magnetism. After the magnetic field is withdrawn, some parts of the watch will be magnetized differently, and it will also affect the watch travel time. Review of the history of watches, after the people of antimagnetic watch began in World War ii. At that time, the world entered the era of vigorous development of electronics and technology engineering, and made breakthroughs in all aspects of mechanical manufacturing, aerospace technology and communication transmission. Human beings also entered the ubiquitous environment of electronic equipment. So people are found, these electromagnetic has a great influence on the accuracy of mechanical watch, the Swiss watch industry have invested in research on antimagnetic watches. The development of science and technology to the present day, we are more in a magnetic field everywhere in the environment. Even so, unless it is a special environment, otherwise many people will ignore the watch antimagnetic, why is this?

Although there are all kinds of magnetic fields everywhere in our lives, the magnetic field is too weak. In fact, some of the electrical and electromagnetic tools used in the daily use are safe, with a magnetic field of only 0.5 Gauss, and the ordinary magnetic field of the cell phone is smaller. But the time to connect to the phone is 10 Gauss, and other common appliances such as computers, washing machines, refrigerators and other short-range radiation are not more than 1 Gauss, and the microwave oven which is called super radiation is also within 5 Gauss. Some of the magnets without noticing are magnetically strong. The small magnetic stickers on the fridge door can reach more than 1000 Gauss, and more powerful magnets can bring tens of thousands of Gauss. The nuclear magnetic resonance equipment in medical field is the magnetic force. Before we interviewed a senior repair master, he also said that if we went to the hospital to do MRI, we must not wear a watch, otherwise ten would go in, and the ten would be magnetically charged. A watch is best not put together with a cell phone. In case of a call, your watch may be very magnetic.

Generally speaking, now (ordinary) watches are using iron nickel alloys such as Nivarox gossamer gossamer, they have a certain ability of our common diamagnetic, mobile phone, computer and other electronic products, generally can stop. But if in some special occupation need to wear a table, please must also be a strong diamagnetic watch. On the market, antimagnetic has done better in Rolex Milgauss, OMEGA AQUA TERRA, OMEGA's engineers and other nations, including the highest, up to 15000 Rolex 1000 Gauss Gauss antimagnetic; antimagnetic, Wanguo 80000 amperes per meter antimagnetic, equal to about 1000 Gauss. It is important to note that here is the antimagnetic ability instead of antimagnetic effect. If the watch is magnetic, as long as it is in time to demagnetize, there will be no big problem.

Shockproof

The shockproof performance of a watch may not be much concerned by many people when buying a watch, but it is really important. In our daily life and work, the watch will inevitably be affected, collision or accidentally fell on the ground, at this time, table machine in the weak parts such as tip may break the pendulum shaft, some parts may have deformation or damage not allowed. Therefore, the wrist watch should take some measures for earthquake protection, such as adopting the shockproof support or installing spring coils between the core and the watch case, so as to protect the watch from damage when it is subjected to impact and collision. A watch with shock resistance is called a shockproof watch. The qualified shock resistance is the impact that can withstand a height of 1 meters. On the market, shockproof quartz watches are famous for CASIO G-shock, the number of mechanical watches Richard Mir, and Nadal's world famous.

Compared with antimagnetic, waterproof, shockproof watch is more natural enemies, especially mechanical watches, most brands of mechanical shock performance can not say how strong. When a heavy impact occurs, it is necessary to pay close attention to the beginning of the error. Because the internal parts may have been loosened or shifted, it is not early to find the returned shop. It will not cause damage to other parts due to the abnormal operation of the long-term parts. If it is unable to confirm the failure of the machine parts, it should be sent back to the store for repair at the first time.
