How to prevent magnetism of mechanical watches?
1) Don't open the back cover at will, so as to prevent dust, fibers, moisture, etc. from invading the timepiece and affecting the normal travel time of the watch;
2) The clockwork must be wound regularly every day. The clockwork can keep the timing accuracy from the watch;
3) Pull out the crown to set the needle, and dial backwards. The crown should be pushed to the winding position after the needle is set, otherwise it'll cause the watch to stop;
4) Wipe the watch case frequently to keep it clean. When the watch is not used, it should be placed in a dry place without camphor balls, and also the clockwork should be wound every once in a while to avoid the lubricant from solidifying and affecting the travel time;
5) In the case of vigorous exercise or high vibration, the watch should be taken off to avoid damage to the machine;
6) Under normal circumstances, the waterproof watch can prevent the intrusion of water vapor in the air. It is not absolutely that water doesn't enter. Do not wear the watch for swimming, showering, washing hands, and washing clothes.
7) Although the watch has certain anti-magnetic properties, it still needs to avoid contact with a powerful magnetic field to prevent parts from magnetizing and causing changes in the watch’s travel time;
8) Don't contact the watch with corrosive liquids and gases for example acid, alkali, salt, etc. Long-term sweat erosion may cause rust on the case. When using the watch in summer, it is best to separate it from the arm around the pad;
9) The mens sports watch has certain speed error, so long as the error does not exceed the conventional, do not often move the speed needle;
10) If you do not understand the repair technique, please do not toggle the parts in the watch or add fuel to prevent accidental loss.
