Friendly reminder:
1. Any waterproof watch should not be brought into contact with hot water or steam (such as hot water bath, sauna, etc.);
2. Try to avoid using it in an environment with large temperature changes. The temperature difference will cause the moisture in the air in the watch to condense, which will cause water inflow and water mist in the watch;
3. If there is fog in the watch, please go to a professional watch repair department for cleaning and maintenance as soon as possible;
4. The watch is a precision instrument after all, please take good care of it and use it; good usage habits can increase the life of your watch, and bad habits will shorten the life of your watch
