Daily watch maintenance and watch knowledge:

1. Please do not bring the watch and magnetic objects close to each other;
2. If there is water ingress, it should be sent to the maintenance point for cleaning immediately to avoid corrosion of the movement;
3. If there are protective sheets or stickers on the back of the watch, please remove them before use, otherwise sweat will penetrate into the backing paper and cause the back of the watch to rust;
4. Do not expose the watch to any solvents or chemicals, otherwise the watch case and strap will be discolored and rusted due to corrosion;
5. Quartz watches can operate stably and accurately within the range of 5°C～35°C at room temperature. Temperature over 50°C will cause battery leakage or shortening.
Temperature lower than -10°C will undermine the battery performance temporarily. When the watch returns to normal temperature, the operation will return to normal;
6. According to their water resistance performance, watches can be divided into diving watches, waterproof watches and non-waterproof watches. The waterproof of the watch depends on the waterproof rubber ring of the watch glass, back cover, crown, etc. to reach the corresponding standard, which is divided into different levels:
(1) SWEAT-RESISTANT: Very easy to understand, just prevent sweat from running inside the watch;
(2) WATER-RESISTANT: It's okay to occasionally run into water. For example, if you accidentally sprayed water on your hands, you don't need to be nervous to take it off and wipe it off. Accidental small splashes in the middle;
(3) 30-meter water resistance (30m, 3ATM, 3bars): The watch with ''30M'' on the watch is a waterproof watch, which can be used for daily washing or use in the rain;
(4) 50-meter water resistance (50m, 5ATM, 5bars): The watch with the word ''50M'' on the watch, that is, the 50-meter water-resistant watch, is the real waterproof watch in the minds of consumers, and can be used for swimming and general housework waterproof watches . Remember not to adjust the crown in the water;
(5) Diving watches (100 meters waterproof, 200 meters waterproof, 300 meters waterproof, etc.) are professional waterproof watches that can be used for underwater work such as swimming and diving.

Reminder:

1. Any watch (even waterproof ones) should not be brought into contact with hot water or steam (such as hot baths, saunas, etc.);
2. Try to avoid using it in an environment where the temperature changes greatly. The temperature difference will cause the moisture in the air in the watch to condense, which will cause water ingress and water mist in the watch. If there is fog in the watch, please go to a professional watch repairer for cleaning and maintenance ASAP;
3. Watches are precision instruments after all, please use them carefully. With attentive treatment, your watch will perform better and longer.
