Maintenance methods: 1. When wearing a watch, hand sweat is corrosive to the watch. In the case of steel, because it is a nickel-chromium alloy, it is corrosion-resistant. In the case of semi-steel copper, it is easy to corrode with sweat for a long time, so you should always use professional

Clean your watch with a watch machine or pad it with plastic to prevent it from being corroded by sweat.

2. Do not open the back of the watch at will to avoid dust movement that may affect the normal operation of the watch.

3. Do not put the watch with mothballs in the wardrobe. Mothballs will cause the watch oil to deteriorate.

4. Do not place the watch in amplifiers, stereos, or TVs to avoid magnetization.

5. If the unworn mechanical watch is stored for a long time, it should be exercised regularly for a short period of time every month. The automatic movement watch should be gently swung back and forth on the wrist for a few minutes or a period of time.

Therefore, this part will not be in a static state for a long time to ensure the normal operation of the watch's performance.
