Description
Mechanical watches do not have batteries, and the entire movement is driven by the swing of the arm's range and the chain. They need to be worn for more than 8 hours to maintain accurate power. Without or after wearing them, there is no power, so time accuracy cannot be guaranteed Windup: Hold the watch in your left hand, pinch the crown with your thumb and index finger in your right hand (rotate your head) downward until the crown pops out, and then twist it up 30 times; After following the previous prompt, use the tip of your right index finger to pull out the crown, and use your right thumb and index finger to gently pull out the crown by one gear (if there is a calendar, it needs to be pulled out to the second gear). Twist it down to adjust to the correct time;.syi
