发明名称 VERFAHREN ZUR HERSTELLUNG VON ZEIGERN FÜR ELEKTRONISCHEANALOGUHREN
摘要 A pair of parallel rectangular windows are punched out in a thin sheet base material having the same thickness as that of a short hand part (13) including a weight part (13a) of a second hand (10) so as to form a hand forming part between the pair of windows and a part in the hand forming part forming a long hand part and a mounting part of a hand is pressed so as to form a thin wall part. Then, the second hand in a final shape is punched out from the base material so that a long hand part (11) and a mounting part (12) are formed with the thin wall part of the hand forming part and the short hand part (13) is formed with an original thickness part. Consequently, the second hand for an analog electronic timepiece in which the weight part (13a) is provided on the short hand part (13) can be easily and securely manufactured only by a press working. <IMAGE>
