Tips for watch maintenance
1. Please do not bring the watch close to magnetic objects.
2. In case of water ingress (air), it should be sent to a maintenance point for cleaning immediately to prevent the movement from rusting.
3. If the back of the watch is attached with protective sheets or labels, 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 let the watch come into contact with various solvents and chemicals, otherwise the case, strap and other parts may discolor and rust due to erosion.
5. Watches (such as quartz watches) can operate stably and accurately within a normal temperature range of 5°C to 35° C. Temperatures exceeding 50°C may cause battery leakage or shorten battery life. 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 run slow or fast. When the watch returns to normal temperature, its operation will resume normally.
6. Watches can be classified into diving watches, water-resistant watches and non-water-resistant watches based on their water resistance. The water resistance of a watch is determined by the waterproof gaskets on the watch glass, back cover, crown and other parts meeting the corresponding standards, and is classified into different grades:
(1) Sweat-resistant: It's very easy to understand. It merely prevents SWEAT from getting into the watch.
(2) General waterproofing (water-resistant) : It's no big deal if you come into contact with WATER occasionally. For instance, if you accidentally spray water on your hands while watering flowers, don't worry. Just take it off and wipe it clean, and there's no problem. In short, it's to prevent the occasional small splashes in daily life.
(3) 30-meter water resistance (30M, 3ATM, 3BAR) : Watches with the words "30M" on them are water-resistant watches. They usually cost a few dozen yuan and can be used for daily washing or in the rain, but mainly to prevent the movement from being damaged by dust and moisture. A 30-meter water-resistant watch, as explained by professionals, can withstand a pressure of 3 kilograms per square centimeter, which is approximately equivalent to the pressure at a depth of 30 meters when at rest. A pressure equivalent to three atmospheres. For us ordinary consumers, we just need to remember that 30m is the basic and primary water-resistant watch.
(4) 50-meter water resistance (50M, 5ATM, 5BAR) : Watches marked with "50M" on them are considered 50-meter water resistant watches. They usually cost several hundred yuan and are truly water-resistant watches in the minds of consumers. They can be used for swimming and general household water resistance. Remember never to adjust the crown in water.
(5) Diving watches (100-meter water resistance, 200-meter water resistance, 300-meter water resistance, etc.) : These are professional water-resistant watches that can be used for underwater activities such as swimming and diving. Their prices are generally over a thousand yuan.

Friendly reminder
1. No water-resistant watch should be worn when in contact with hot water or steam (such as taking a hot bath or sauna).
2. Try to avoid using it in an environment with significant temperature changes. The temperature difference can cause the moisture in the air inside the watch to condense, leading to water ingress and the formation of water mist inside the watch. If there is fog inside the watch, please take it to a professional watch repair department for cleaning and maintenance as soon as possible.
3. After all, watches are precision instruments. Please use them with care. Good usage habits can extend the lifespan of your beloved watch, while bad habits will shorten it.
