(1) When wearing a watch, the sweat on your hands is corrosive to the case. All-steel case has better corrosion resistance because it is made of nickel-chromium alloy, and semi-steel case is made of copper, which is easy to corrode after long-term contact with sweat. You should always wipe off sweat with a soft cloth or pad a plastic watch stand 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 radio or TV to avoid magnetization.
(5) Watches that are not worn for a long time should be wound regularly once a month to prevent the parts from being in a static state for a long time, so as to ensure the running performance of the watch machine.
