How to use and maintain the watch

(1) When wearing a watch, the sweat on the hands is corrosive to the case. The all-steel case is made of nickel-chromium alloy, which has better corrosion resistance. The semi-steel case is made of copper. It is accessible to rust when it is in contact with sweat for a long time. Frequently wipe off sweat with a soft cloth or pad the plastic watch holder to prevent it from being corroded by sweat.
(2) Do not open the back cover of the watch at will to prevent dust from entering the movement and affecting the regular operation of the eye.
(3) Do not put the watch in a wardrobe with mothballs to prevent the watch oil from deteriorating.
(4) Do not put the watch on the radio or TV to avoid magnetization.
(5) The watch should be placed in a dry place for long-term storage of unworn watches.

How to judge whether a watch is accurate?

(1) If the time of the watch is set every few days, which is consistent with the time signal of the radio station, this is an accurate watch.
(2) The time of the watch is consistent with the time signal of the radio station at the beginning, but there is an error every day after running. Then the cumulative increase, but the error value increased every day is the same. If the travel time error value does not exceed the quality standard of the watch, this is also a qualified watch. If the error value exceeds the specified standard, you can adjust the speed needle to make it more accurate.
(3) If the timekeeping signal of the watch and the radio station is aligned, sometimes it is slow, sometimes it is fast, there is no certain regularity, but the error is tiny, which may be related to the state of use, and it is also a qualified watch. Suppose it is found that the error is too large, irregular, and cannot be adjusted by moving the speed needle, and its accuracy cannot be guaranteed. In that case, it needs to be inspected and corrected to make the travel time meet the specified standards.

Why sometimes are there rust spots on the all-steel case?

Generally, all steel watches will not rust, but everything is relative. There are many types of stainless steel. The sweat discharged by the human body contains hydrochloric acid. Suppose the watch is worn on the hand, eroded by work for a long time, or allowed to accumulate acid, alkali, and salt dirt without wiping it off. In that case, rust spots will gradually appear on the watch case, especially on the concave part of the back cover. Comes out often. Therefore, you should pay attention to the maintenance of the watch at ordinary times and often wipe off the dust deposits and sweat on the watch case. In addition, try to avoid wearing the watch in strong acids, alkalis, and other occasions so that the all-steel case will not appear with rust spots.

Is it not reasonable to sleep wearing a luminous watch?

Wearing the watch on the wrist to sleep will have adverse effects on the body if the watch is a luminous watch. This is because the luminescent material coated on the pointer and dial of the brilliant clock is mainly a mixture of radium and zinc sulfide. The rays emitted by radium can excite the zinc sulfide crystal to emit light. Nine hours of radium radiation is harmful to the human body. Therefore, before going to bed, it is best to take off the luminous watch and put it on the table.
