Maintenance Tips for Watches:
1. Please do not bring your watch close to magnetic objects.
2. If there is any water intrusion (air in the system), it should be immediately sent to the maintenance point for cleaning to prevent corrosion of the mechanism;
3. If there are protective film or stickers on the back of the watch, please remove them before use, otherwise, sweat will seep into the protective paper, causing the back of the watch to rust.
4. Please do not expose your watch to various solvents and various chemical substances, or the watch case and strap may become discolored or corroded due to erosion.
5. Watches (such as quartz watches) can operate stably and accurately within the temperature range of 5°C to 35°C. Temperatures exceeding 50°C can lead to battery leakage or shorten the battery life. Please do not leave the watch in a low-temperature environment of -10°C for a long time, as cold air can cause the time to slow down or speed up. When the watch returns to normal temperature, the operation will return to normal;
6. Watches can be classified according to their water resistance into diving watches, waterproof watches, and non-waterproof watches. The water resistance of a watch is achieved through the use of waterproof gaskets at places such as the crystal, case back, and crown, which meet certain standards. These are divided into different levels:
(1) Sweat-resistant: very straightforward, simply preventing sweat from entering the watch.
(2) General waterproof (WATER-RESISTANT): means it's okay if you occasionally get a little water, like if you accidentally get water on your hand while watering a plant, don't worry, just take it off and wipe it clean, and it'll be fine. In short, it's designed to protect against the occasional small splashes in daily life.
(3) 30-meter water resistance (30M, 3ATM, 3BAR): A watch with the word "30M" on it is waterproof. The price is usually only a few ten yuan. It can be used for daily bathing or in the rain, but mainly to prevent the movement from being damaged by dust and moisture. The explanation for 30-meter water resistance is that each square centimeter area can withstand 3 kilograms of pressure. It is equivalent to the pressure of 30 meters deep water, which is the same as the pressure of 3 atmospheric pressures. For us ordinary consumers, we just need to remember that 30m is the basic level of waterproof watches.
(4) 50米防水 (50M, TM, 5BAR): A watch with the word "50M" on it is a 50-meter water-resistant watch. The price is usually a few hundred yuan. It is a watch that consumers think is waterproof, and it can be used for swimming and general household tasks. Remember not to adjust the watch crown in water.
(5) Diving watches (100-meter water resistance, 200-meter water resistance, 300-meter water resistance, etc.): These are professional waterproof watches that can be used for underwater activities such as swimming and diving, with prices usually starting from a thousand yuan.

Friendship Reminder:
1. Any waterproof watch should not be exposed to hot water or steam (such as taking a hot bath or sauna).
2. Try to avoid using the watch in environments with large temperature changes, as the temperature difference can cause moisture in the air to condense, leading to water ingress and mist formation inside the watch. If mist forms inside the watch, please go to a professional watch repair shop for cleaning and maintenance as soon as possible;
3. After all, a watch is an instrument, please use it with care. Good habits can extend the life of your favorite watch, while bad habits can shorten its life.
