(1) When wearing a watch, the sweat on your hands is corrosive to the watch case. Always wipe off the sweat with a soft cloth or pad the plastic watch holder to prevent it from being eroded by sweat. (2) Don't open the back cover of the watch at will to avoid dust entering the movement and affecting the normal work of the watch. (3) Don't put the watch in the wardrobe with mothballs, so as not to spoil the watch oil. (4) Don't put the watch on the stereo or TV to avoid magnetization. (5) Watches that are not worn for a long time should be wound regularly once a month, and watches with automatic movement should be gently swung back and forth for a few minutes or worn on the wrist for a period of time to make them automatically wound. Parts will not be in a static state for a long time, which ensures the running performance of the watch machine. (6) Ordinary mechanical watches are wet. You can press dry cotton on the watch and bake it with a 40-watt bulb for 5 minutes to evaporate the water in the watch. If the electronic watch is affected by tide, take some small pieces of calcium chloride and wrap it with gauze; Then open the cover of the electronic watch, and put the wrapped calcium chloride and the electronic watch into an airtight plastic bag or glass bottle for sealing. Generally, it takes about 3 hours to remove moisture and make the electronic watch return to normal. For watches with severe moisture, the moisture absorption time can be appropriately extended. (7) When removing the outer packaging of the watch, be sure to keep the packaging box used to protect the watch. These boxes for protecting watches can provide the safest protection for watches when they are not worn, so it is absolutely necessary to keep the boxes. (8) Under normal circumstances, it is best not to wear the same watch every day. You should prepare several different watches to use alternately, which can not only enrich your personal style, but also avoid dust and dirt from being concentrated on the same watch. (9) Don't sleep with a watch on. If your watch is a luminous watch, it will bring bad effects to your body. This is because the luminous materials coated on the hands and dials of luminous watches are mainly a mixture of radium and zinc sulfide, and the radiation emitted by radium can excite the zinc sulfide crystal to emit light, which will cause harm to the body. (10) Surface covering renovation. After many lines are scraped out of the watch cover, you can first drop a drop or two of water on the watch cover, and then squeeze a little toothpaste to wipe it, so that the lines can be removed and the watch cover can be as new.
