Daily watch maintenance and watch knowledge:

1. Please do not approach watches and magnetic objects;

2. If there is water inflow (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;

V. Watches (quartz watches only) can operate stably and accurately in the range of 5°C to 35°C at normal temperature. If the temperature exceeds 50°C, the battery will leak or shorten.

Battery life. 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) SWEAT-RESISTANT: it is easy to understand and only prevents SWEAT from running into the watch;

(2) general WATER-RESISTANT: it doesn't matter if you touch the WATER occasionally. For example, if you accidentally spray the flowers on your hands, there 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, can be used for daily washing or rain use, 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 that 30m is the most basic and primary watrproof watch;

(4)50m waterproof (50m, 5ATM, 5BAR): the watch with the word "50m" on the watch, that is, 50m watrproof watch, is the real meaning of watrproof watch in consumers' minds, waterproof watches for swimming and general housework. Remember not to adjust the watch handle in the water;

(5) diving watch (100 m waterproof, 200 m waterproof, 300 m waterproof, etc.) is a professional watrproof watch, which can be used for underwater work such as swimming and diving.

Warm 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 it in an environment with great temperature changes. The temperature difference will condense the moisture in the air in the table, thus causing water inflow and water mist knot 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 precision instruments. Please take good care of them. Good habits can increase your watch life, bad habits will shorten your watch life.
