A manual winding feature which needs to be wound by the wearer using the winding crown. This winds the mainspring up which then releases its energy to power the watch. If you haven't worn an automatic in a while, it is best to wind the stopped watch before putting it on. 10 to 15 turns of the crown is usually enough to give full power to the mainspring. But be aware that the barrel in an automatic movement doesn't have a hook so that you won't feel any resistance when the mainspring is fully wound. Do not over wound by winding it more than 20-30 at one time. It is preferable, however to wind these watches every day and at about the same time because this will increase their precision. Try to wind your watch at the same time every day. This is extremely beneficial for the mechanism. You may want to make it a routine, winding it once every morning when you wake up.
Which way do I turn the crown to wind the watch?
Almost all mechanical watches wind by turning the crown clockwise (if you are looking straight at the logo on the crown). When you are looking at the face of the watch, this means rotating the upper face of the crown upwards, toward the 12.
