(1) wear watches, the hands sweat on the case of corrosive, steel case because it is nickel-chromium alloy, corrosion resistance better, semi-steel case of copper, long-term contacts with sweat, easy corrosion, should often with a soft cloth wipe sweat or plastic table mat care to prevent its erosion sweat.
(2) Do not open the back cover, so as not to affect the movement of dust into the normal operation of the watch.
