Tips for maintaining a watch:

1. Please do not bring the watch close to magnetic objects;

2. In case of water ingress (air presence), it should be sent to the repair station for cleaning immediately to prevent the movement mechanism from rusting;

3. If there are protective sheets or labels on the front and back of the watch, please remove them before use. Otherwise, sweat will seep into the protective backing paper, causing rusting of the front and back.

4. Do not expose the watch to various solvents and chemicals; otherwise, the case and straps may change color or rust due to erosion.

5. Watches (only quartz watches) can operate reliably and accurately within the range of normal temperature 5°C to 3.5°C; temperatures exceeding 50°C may cause battery leakage or reduced battery life

Watch battery life. Do not leave the watch in a low-temperature environment of -10°C for extended periods, as cold air can cause the time to move slower or faster. When the watch returns to normal temperature, it will resume normal operation.

Normal;

6. Watches can be classified into diving watches, waterproof watches, and non-waterproof watches based on their water resistance. Water resistance is achieved through waterproof rubber seals in the watch glass, back cover, and crown.

Meeting the corresponding standards, categorized into different levels:

(1) Sweat-resistant: It is easy to understand, simply preventing sweat from entering the watch;

(2) General water resistance (WATER-RESISTANT): It means it’s okay if water touches it occasionally. For example, if you accidentally spray water on your hand while watering the flowers, there’s no need to worry.

Just remove it and wipe it clean, nothing else is needed. In any case, it’s to prevent small droplets that happen accidentally in daily life.

(3) 30 meters water resistance (3M, 3ATM, 3BAR): Watches marked with "3M" are waterproof models suitable for daily washing or use in rain, but mainly

To prevent the movement from being damaged by dust and moisture, it has a 30-meter water resistance. According to professionals, each square centimeter can withstand a pressure of 3 kilograms, approximately at rest

The state equivalent to the pressure at a depth of 30 meters, which is equal to 3 atmospheres of pressure. For us ordinary consumers, all we need to remember is that 30m means it is a waterproof watch.

Basic and beginner-level is sufficient;

(4) 50 meters water resistance (50M, 5ATM, 5BAR): Watches marked with "50M" indicate a 50-meter water resistance feature, which is what consumers actually mean by this term.

Waterproof watches, watches that can be used for swimming and general household tasks. Remember not to calibrate the watch while it is in water;

(5) Submersible watches (100 meters water resistance, 200 meters water resistance, 300 meters water resistance, etc.): These are specialized waterproof watches suitable for swimming, diving, and other underwater activities.

Friendly reminder:

1. Any waterproof watch should not be used when exposed to hot water or steam (such as taking a hot bath or using sauna).

2. Try to avoid use in environments with significant temperature changes, as the temperature difference can cause moisture in the air inside the meter to condense, leading to water ingress and water mist formation inside the meter.

If fog appears inside the watch, please go to a professional watch repair shop as soon as possible for cleaning and maintenance;

3. After all, watches are precision instruments; please use them with care. Good usage habits can extend the lifespan of your watch, while bad habits will shorten it..
