A: The mechanical watch is driven by the winding. If the winding is not enough, it will stop/slow down. Please turn the crown clockwise to wind the watch 30 times. Q: How many turns does it take to wind the chain manually? A: The upper chain is one circle, and the number of winding circles can reach 35~40 circles, but in order to maintain the watch well, it is best to wind up 70% of the chain at a time. Note that the manual winding must not be 100%, and you need to leave a little leeway . Generally speaking, when the crown turns to the number of turns close to the upper limit, you will feel that the mainspring is gradually tightening. When the resistance increases, it should stop rotating to avoid excessive winding and damage to the internal parts.
