PROBLEM TO BE SOLVED: To provide an automatic winding device of an automatic winding wrist watch. SOLUTION: A cone rotor 2 covered with a sponge is projected from the center of a slanting plate 1 in a box 4 to the front. As a wrist watch 3 is inserted into the root of the cone rotor 2 which is covered with the thick sponge, the fixing becomes more stiff and the device also can deal with the variation of belt length of the wrist watch 3. When the cone rotor 2 slowly rotates, a pendulum assembled in the wrist watch 3 swings around to wind a spring. |
