FQA
1. What should I do if there is water inside the watch?
If there is only a small amount of water vapor inside the watch, it will disappear automatically over time. You can also wear the watch upside down on your wrist; after two hours, the water vapor should disappear. If there are water droplets inside the watch, you should have the watch repaired as soon as possible.
2. Special Note:
Fully automatic mechanical watches rely on arm movement for automatic winding, so they must be worn for more than 8 hours a day to ensure timely and accurate operation. Some automatic mechanical watches can also be manually wound to supplement power: with the crown not pulled out, turn it clockwise 15 times. Mechanical watches without manual-winding functionality cannot be powered by manual winding.
3. Warning:
From 8:00 p.m. to 4:00 a.m. the next day, please do not adjust the calendar, weekday, or month quick-set buttons. Otherwise, the calibration may fail, the quick-set buttons may become blocked or damaged, and the movement may be damaged. Mechanical watches should be kept away from televisions, computers, and other devices with magnetic fields to avoid affecting their operation.
