In urban white-collar workers, many people have the habit of wearing watches in their daily work and life. But many people love their watch when to add time, how to set it up, where the failure to repair? Wait and these issues are ignorant, and today we come to help you organize a few very typical problems , For everyone doubts. 1. Even when your watch goes normal, the watch brand will also recommend wearing a watch table friends, the mechanical watch must be sent regularly to the maintenance. Why is this so? Like a car, a mechanical watch needs to be lubricated regularly to keep it moving smoothly. With the passage of time, the effect of lubricating oil will deteriorate, and the friction between the moving parts will increase, resulting in wear and tear are not allowed to go. In addition, the friction will produce very fine dust, will wear watch movement parts. 2. How long does it take to maintain a mechanical watch? The manufacturers' suggestions are different, but most are every three to five years. 3. When the watch is sent to conservation, what happens? The watch will be disassembled, then the strap and case cleaned with ultrasound and polished. Mechanical parts are chemically cleaned and inspected, while worn parts are replaced. After that, the movement will be reassembled, oiled and speed. Finally, if the watch is a waterproof watch, its waterproof function will be tested. 4. Where should you take the watch to repair or refurbish? If the watch is under warranty, the warranty may not be valid unless you get an officially authorized service center. You can get a table from the manufacturer, which lists the official authorized repair center. If the warranty period is over, you can take the official authorized center or a larger store repair shop. How much does it cost to maintain once? Changes due to price will be very large, but in general, a non-complex automatic mechanical watch, the cost of maintenance once, it will exceed 500 yuan, and sometimes even greatly exceeded. However, a constant principle is that the more expensive the brand, the higher the cost of renovation. How long does the watch need to stay in the store? This is the same, and varies from store to store, but the time it takes to get your watch back for repair is often two or three weeks. Quartz watch also need to be the same as the mechanical watch, regular maintenance it? Not needed The movements of the quartz watch require little maintenance like mechanical movements, because they have far fewer moving parts - only the gear train drives the hands. The electronic watch has no moving parts at all. Most quartz watch the real need, just open the case for the battery, remove the accumulated dust. However, some expensive quartz watches or watch-like movements, their gear train, should be lubricated every 8 to 10 years. For those cheap quartz watches, this is not necessary. 8. watch waterproof function how long need to test? All waterproof watches, each time you change the battery or open the case for whatever reason, the need for testing. That is because the case is open, the sealed waterproof gasket will fall off. These gaskets (or type 0 gaskets) are located in the case, the case and the back cover, crown, surface crystal connections. For this reason, when the battery inside a waterproof watch needs to be replaced, it is necessary to take the watch to a service center that has a waterproof performance testing instrument. In some cases, waterproofing needs to be checked even during battery replacement. A senior watch practitioner said: "If you want to wear in the water, or frequent exposure to sweat environment, it should be tested at least once every two years; if the frequent exposure to water, will be tested once a year." 9. Do you need to attach the mechanical watch every day? If you do this, the watch will be more accurate. "When the watch is full, it's always better than when it's loose," says Daniel Fenwick, technical manager at a senior customer service center at Swatch Group. If you do not intend to wear a watch, it is best for it on the article. This prevents the movement lubricant from condensing. Of course, this does not apply to automatic movement or automatic winding watch. This type of table simply in the initial article, to make it start walking time. If the wearer is quite active and wears 12 to 15 hours a day, it will always be full. 10. When you set the watch, the rotation of the crown will have anything to do? On most mechanical watches, it has no effect. However, some mechanical watches, especially those with a calendar function, you should only move the pointer clockwise. In the manufacturer's operating instructions, including the adjustment of direction. In the quartz watch, whatever direction to rotate, it does not matter. However, the manufacturer pointed out that by setting the watch in the following way, the voids in the minute hand can be eliminated (a quartz watch, unlike a mechanical watch, often with voids in the minute hand due to the lack of tension between its gear trains): Clockwise Rotate the minute hand until it is adjusted to its place a few minutes ago and finally turn it counterclockwise to call it back to the correct position. 11. Can cold and heat affect the watch's accuracy? Cold and hot quartz watch will affect the time recording capabilities. Extremely stable quartz crystal vibration is invincible quartz watch accuracy guarantee. After being cut, they perform best at room temperature. When the temperature reaches 38 degrees will make the watch walk 1 second a day. Extreme temperatures also affect the accuracy of the mechanical watch. One of the reasons is that cold and heat can cause expansion or contraction of watch movement parts; another reason is that cold and heat can affect the viscosity of the movement lubricant, thus affecting the accuracy of the movement. 12. What other factors will affect the accuracy of a watch? In a mechanical watch, the habit of wearing, the time of winding up, the length of time worn each day, and the position where the watch should be worn, all play a crucial role in determining the watch's time-walking style. Although a typical mechanical watch may move more or less every 3 minutes a month, it is possible to reduce this error by adjusting the watch to suit the wearer's habit. None of these factors will have any impact on the quartz watch. For quartz watches, temperature is the only variable that can affect travel time accuracy. Is it possible to wear a mechanical watch while exercising? In general it is fine. All of today's mechanical watches are equipped with anti-vibration devices that protect the watch's pivot axis, the weakest part of the watch movement, and are most vulnerable to impact. For example, this device is usually used to protect the watch from the impact of hitting tennis or golf balls. Nonetheless, sometimes a small change, such as a heavy bump, not only ruins the balance but also damages the rotor shaft, which is a gear train that protects some of the automatic movements. So when you exercise, decide whether to wear a watch, which is related to risk assessment. Is it the same for quartz watches? When doing exercise, damage to a quartz watch machine is unlikely. Because the quartz watch has no brittle parts - the balance pivot, which is why in the mechanical watch, shockproof device is very necessary. Of course, whether it is a quartz watch or a mechanical watch, you can damage other parts of it, like a watch crystal. 15. What can damage scratch sapphire crystal it? Do not be misled by the term "scratch-resistant". It does not mean "scratch". The most scratch-resistant crystal is made of synthetic sapphire, a very hard mineral with a Mohs hardness of 9 (diamonds, the hardest natural substance known to man, having a Mohs hardness of 10 ). Despite the high level of sapphire hardness, it can still be scratched by some materials. Found in some furniture and walls of synthetic stone, rubbed the surface, you can scratch the sapphire. And, you also have to keep in mind that the more scratch-resistant the material, the more fragile it is, so scratch-resistant crystals may be more likely to be crushed or chipped than non-scratch resistant materials. 16. quartz watch battery life for how long? A silver oxide battery life can be two to three years. 17. You set the time, or when you are in the mechanical watch on the chain, if you pull the crown too hard, it will ruin the watch? These things are almost impossible to ruin a watch, unless you really pull too hard. Similarly, in theory, it is possible to damage the main winding over the chain. 18. If you do not wear watches for a few days, the quartz stem pull out the handle, you can save the energy of the battery, is this true? The handle shaft is pulled out, saving 75% to 80% because gears and hands no longer operate. However, when you think about a silver oxide battery, you lose only 5% to 8% of its energy every year, leaving you with almost the same savings and losses. Another argument against saving energy with this method is that if the gears in the gear train stand still for a long time, the lubricant will condense.
