Watch Usage Instructions:

1. When the second hand of a quartz watch jumps or stops every few seconds, it indicates that the battery is exhausted. It is essential to replace the battery in time to avoid any damage to the movement caused by a dead battery remaining in the watch for a long time.

2. The normal working temperature for temperature quartz watches is -5 degrees to 50 degrees Celsius. Please do not place the watch in an environment with high or low temperatures (such as taking a sauna, soaking in hot springs), otherwise it may affect the accuracy of the watch and the lifespan of the battery.

3. Fully automatic mechanical watches require the wearer's arm movement to automatically wind the mainspring, so they must be worn for at least eight hours a day to ensure accurate timekeeping. If the watch is not worn enough during the day, it may not run properly, so it is recommended to swing the watch horizontally for one minute when taking it off at night to recharge the mainspring.

4. Water-resistant watches have a water-resistant function in daily life, but they should not be worn for swimming or diving. It is recommended not to wear them while taking a bath to avoid water entering the movement, which could cause a short circuit or rust and affect the watch's accuracy.

5. Watches made of high-hardness materials (such as hard alloy, ceramic, sapphire, etc.) have poor impact and shock resistance. They should be avoided from falling or colliding, and should not be subjected to friction with high-hardness objects.

6. Magnetic watches should be kept away from objects with strong magnetic fields, such as televisions, magnets, and speakers, to prevent magnetic fields from damaging the movement and affecting the accuracy of the watch's timekeeping.

7. Chemical items watches should be avoided from contact with various solvents (e.g., alcohol, gasoline), mercury, cosmetics, spray, adhesive, detergent, paint, and other corrosive liquids or gases, to prevent the surface of the watch case and strap from being eroded, discolored, degraded, or damaged.

8. Carefully clean the dust, moisture, and humidity that may accumulate on the watch case and strap to prevent rust. Therefore, it is recommended to regularly clean the watch with a soft dry cloth.
