Zusammenfassung:A method of manufacturing a wrist watch, in which a negative ion or a far infrared light is generated, is provided to activate operation of a cell by attaching composition for discharging the negative ion or the far infrared light. A method of manufacturing a wrist watch, in which a negative ion or a far infrared light is generated, includes the steps of forming a predetermined size of groove(12) at a center of a case cover(10) of the wrist watch, mixing a natural mineral powder 50wt% with a molding material 32wt% and a hardener 18wt%, injecting the mixture into the groove of the case cover, sintering the mixture in a heating furnace at 100‹C for 25-30 minutes, cooling the case cover for 10-15 minutes, secondarily sintering the mixture in the heating furnace at 100‹C for 25-30 minutes, and cooling the case cover.
