摘要

A method of easily and securely manufacturing, by a press working only, a second hand for analog electronic timepiece having a weight part (13a) on a short hand part (13), comprising the steps of punching out a pair of parallel rectangular windows in a thin sheet base material having the same thickness as that of the short hand part (13) including the weight part (13a) of a second hand (10) so as to form a hand forming part between the pair of windows, pressing a part of the hand forming part forming a long hand part and a mounting part of the hand so as to form a thin wall part, and punching out the base material, in the final shape of the second hand, so that the long hand part (11) and mounting part (12) are formed with the thin wall part of the hand forming part and the short hand part (13) is formed with the original thickness part.
