Caution, do not overwind a mechanical watch means that when winding a mechanical watch, you should stop turning the crown as soon as you feel significant resistance, as continuing to force it could damage the internal mechanism by over-tensioning the mainspring; essentially, the watch will tell you when it is fully wound by providing resistance, so don’t push past that point.
