1. Maintenance Common Sense
(1) When wearing a watch, the sweat on the hand is corrosive to the case. The all-steel case is nickel-chromium alloy, which has better corrosion resistance. The semi-steel case is copper. It is easy to corrode because of long-term contact with sweat. It should be wiped with soft cloth or padded with plastic bracket to prevent it from being corroded by sweat.
(2) Do not open the back cover of the watch at will, in order to avoid dust entering the machine core affecting the normal work of the watch.
(3) Do not put your watch in the wardrobe with camphor balls to avoid deterioration of the watchoil.
(4) Do not put your watch on the radio or TV to avoid magnetization.
(5) Watches that have not been worn for a long time should be clothed regularly once a month so that parts do not remain stationary for a long time, so as to ensure the operation performance of the watches.
2. Table renovation
After many lines have been drawn on the watch cover, one or two drops of water can be put on the watch cover first, and then a little toothpaste can be squeezed to wipe off the lines and make the watch as new as before.
3. Remove the accumulated water in the table
When water enters the watch case carelessly, a granular substance called silica gel can be used to put the watches that have accumulated water into an airtight container together. After several hours, the watches are taken out and the accumulated water disappears completely. This method is simple and economical, without any damage to the accuracy and life of the meter. Silica gel, which has absorbed water for many times, can be dried for several hours at 120 (?) C. It has renewable water absorption capacity and can be used repeatedly.
