Common sense of watch maintenance:
1. Please do not approach the watch and magnetic objects;
2. In case of water inflow (with air), it should be sent to the maintenance point for cleaning immediately to avoid corrosion of the movement;
3. If the back of the watch is attached with protective sheet or pasted with sticker, please remove them before use, otherwise sweat will penetrate into the base paper, causing the back of the watch to rust;
4. Do not contact the watch with various solvents and chemicals, otherwise the watch case strap will change color and rust due to erosion;
5. Watches (such as quartz watches) can operate stably and accurately within the range of 5°C to 35°C at normal temperature. If the temperature exceeds 50°C, battery leakage or battery life will be shortened. Do not put the watch in the low temperature-10°C environment for a long time, because the cold air will cause the time to slow or fast. When the watch returns to normal temperature, the operation will return to normal;
6. Watches can be divided into diving watch, watrproof watch and no watrproof watch according to waterproof performance. Watch waterproof is based on waterproof rubber ring of watch glass, back cover, watch handle, etc. to reach the corresponding standards, divided into different levels:
(1) sweatproof (SWEAT-RESISTANT): it is easy to understand and only prevents SWEAT from running into the watch;
(2) General waterproof (WATER-RESISTANT): It doesn't matter if you touch the WATER occasionally. For example, if you accidentally spray the flowers on your hands, don't be nervous, it is no problem to take it off and wipe it clean. In short, it is to prevent accidental small water flowers in life;
(3)30m waterproof (30m, 3ATM, 3BAR): Watch with the word "30M" on the watch, this is watrproof watch, the price is generally tens of yuan, it can be used for daily washing or rain, but it is mainly to prevent the movement from being damaged by dust and moisture. 30 meters waterproof, the professional's explanation is that each square centimeter area can withstand a pressure of 3 kilograms, which is equivalent to a water depth of 30 meters in a static state, equivalent to a pressure of 3 atmospheres. For our ordinary consumers, we only need to remember 30m, which is watrproof watch basic primary;
(4)50m waterproof (50m, TM, 5BAR): Watch with the word "50m" on the watch, that is, 50m watrproof watch, the price is generally several hundred yuan, it means watrproof watch in consumers' minds, and can be used for swimming and general household waterproof watches. Remember not to adjust the watch handle in the water;
(5) diving watch (100 m waterproof, 200 m waterproof, 300 m waterproof, etc.): It is a professional watrproof watch, which can be used for underwater work such as swimming and diving, and the price is generally over 1,000 yuan.

Friendly reminder:
1. Any watrproof watch should not bring hot water and water vapor (such as hot water bath, sauna, etc.);
2. Try to avoid using in the environment where the temperature changes greatly. The temperature difference will condense the moisture in the air in the table, thus causing water inflow and water mist junction in the table. If there is fog in the watch, please go to the professional watch maintenance department for cleaning and maintenance as soon as possible;
3. After all, watches are instruments. Please take good care of them. Good usage habits can increase the life span of your watch, and bad habits will shorten the life span of your watch.
