How to wind a mechanical watch?

　　Mechanical watches feature exquisite craftsmanship and are convenient to use, but do you know how to wind a mechanical watch? Below, Xiaoya will tell you the methods for winding a mechanical watch for your reference.

　　Winding principle of mechanical watches

　　The vast majority use an eccentric oscillating weight (automatic rotor or automatic weight). Its shape is like a semicircular disc, made of a relatively heavy metal with a thicker edge, so most of the mass is on the edge of the rotor. It rotates by utilising gravity and the swing of the wearer's arm, driving a set of gears to wind the mainspring.

　　Sometimes the position change and response of the automatic rotor cannot keep up with the rhythm of the arm swinging. Automatic watches also have an automatic winding efficiency, which involves design and structural issues. Even the weight of the automatic rotor differs between watches. Currently, the best winding efficiency comes from the so-called "ratchet and pawl" structure, such as the one used in Seiko and some IWC watches. The Japanese call it the "Magic Lever automatic winding structure", while the Swiss call it the "Pellaton automatic winding system". Moreover, it is relatively sensitive to changes in position. It is said that the winding efficiency of this type of automatic structure is more than 30% higher than other general structures.

　　Winding method for mechanical watches

　　Hold the watch in your left hand and turn the crown clockwise with your right hand, generally for 20-30 turns. For watches with a protection function, the crown will spin freely once it is fully wound.

　　Factors affecting automatic mechanical watch winding

　　(1) This is related to the size of the crown; a larger crown is easier to grip and apply force to, whereas a smaller one tends to slip. It also depends on how tightly fitted the crown is with the case tube; if it is relatively tight, it will also affect smooth winding.

　　(2) This is related to the gear transmission ratio for winding. Different watch movements have different gear ratios in the winding system, including the number of teeth on the intermediate wheel, ratchet wheel and crown wheel, meaning the winding speed varies.

　　(3) The number of working turns of the mainspring also varies. The working turns of a watch mainspring typically range between 6-10 turns; those with more working turns will require more winding rotations.

　　(4) This is related to winding force. I always wind the mainspring fully with a firm force myself, whereas some people might wind it more delicately, so the degree of rotation for the crown each time will differ.
