How do I wind it manually? The manual winding method for this watch is: do not pull out the crown, turn the crown directly clockwise. How to check the accuracy of a mechanical watch？ Please wind the watch fully, re-calibrate the time, and then leave the watch to observe for 24 hours to see if its timekeeping error is between 20 seconds slow and 40 seconds fast. How to do if there is water inside the watch? If there is only a small amount of water vapour, wear the watch backwards on your wrist and it will disappear after a while. If there are some water drops inside the watch, you should have the watch repaired as soon as possible. What do I need to pay special attention to? Fully automatic mechanical watches, which rely on the movement of the arm to wind themselves, must therefore be worn for more than 8 hours a day to ensure accurate timekeeping.
