Mechanical watch is driven by mechanical gear and spring rotation, rotation will inevitably produce friction, so the time must be refueling, lubrication, in order to reduce the wear rate of parts. Otherwise, wait until the fault is sent to repair, often the problem is already very serious. It is best to return home every year to check to see if there is improper use or water. In particular, Taiwan's hot and humid climate, sweat, rain and dirty air accumulate over the years, causing chronic erosion of machinery, and the frequency and degree of damage are much higher than Europe, the United States and Japan, so "regular inspection" is very important; Then every three years to make a thorough cleaning, maintenance. Usually the watch shows that 30 meters or 50 meters waterproof refers to the data measured in the laboratory, with pure water, usually the waterproof needs of the watch is limited to wearing a shower, washing hands, must not swim, dive, bath, which will cause serious damage to the watch, these are the maintenance of mechanical watches common sense. What to do after the Citadel watch has a problem 1. If the watch is abnormal, it should be immediately sent to a special watch inspection. 2. Different occasions should wear different watches, such as sports when it is best to use waterproof and excellent shock resistance sports watches. 3. The mechanical automatic watch must be in the case of sufficient activity, that is, it must be worn for more than 10 hours a day to operate normally. 4. A watch labeled WATER RESESTENT or 3ATM on the cover is generally only suitable for water or light rain under no pressure. 5. Mechanical watches are affected by the tide, dry cotton can be pressed on the watch, and then baked with a 40-watt light bulb for 5 minutes, the moisture in the table can all be evaporated. 6. After the watch is marked out a lot of lines, you can drop one or two drops on the watch, and then squeeze a little toothpaste to wipe, you can remove the lines and make the watch as new. Seven. Because the internal mechanical structure of each watch is different, under normal use, the error of the mechanical watch or mechanical automatic watch is within 30 seconds per day, and the error of the quartz watch is lower and more accurate. In particular, we remind you that any watch should not be worn in warm water or the bathroom, even if your watch is a waterproof watch, the water vapor molecules around are relatively small, it is easy to penetrate the case, causing internal mechanical damage. 9. Usually should prepare several different watches for alternate use, to avoid dust, body scale all concentrated on the same watch, so as not to use every day caused by regular wear and tear of the watch band, the watch will look very old. For those mechanical watches that are not worn for a long time, they should also be regularly wound to make their chips rotate. As for the quartz watch, its battery life is generally 1 to 2 years, the battery should be replaced regularly, the battery should also be replaced when the seal ring of the watch, and its waterproof test. A watch with a battery replacement prompt function should be replaced within 3 weeks after the prompt appears. When wearing, in addition to avoiding friction and collision with objects that exceed or have the same hardness, it should be cleaned regularly to maintain its good decoration. In addition, seawater, salt bath, perfume, shampoo, nail polish, nail polish remover and other cosmetics containing chemical substances have a certain corrosion of the gold layer and metal surface of the watch, which should be avoided. Moreover, even if the west iron city table has waterproof function, not what water can be prevented, 30 meters waterproof, you can only prevent hand washing water, face water, rain, car splash, etc., if the shower, swimming, etc., the watch must be unbearable. Master Ma reminds consumers that no matter how much waterproof depth, can not wear a watch sauna, steam heat will accelerate the aging of waterproof rubber ring, can not protect the movement normally. Generally speaking, the mechanical watch should be maintained 1 time in 2 to 3 years, maintenance, to disassemble all the parts of the watch, wipe the movement with 120 gasoline, and then clean the other instruments in the watch by professional equipment, and finally oil and assembly. In addition to the parts in the watch, the shell of the watch should be polished when cleaning the Citroen watch. Because watches have very high requirements for technical parameters, cleaning a watch is a very fine job, and professional cleaning usually takes 5 days to complete. The old iron City watch after such a complex professional cleaning, generally can be turned over to 80% new.
