PURPOSE:To prevent the contact of a hand, by providing magnetic electrodes having the same polarity between the dial of a wristwatch or the parts fixed to said dial and the hand as well as the hand and the opposed surface of the hand. CONSTITUTION:In the time display part of a wristwatch, the set type 10, the min hand 5 and the sec hand 3 fixed to a dial 9 are magnetized and the upper surface 10a of the set type 10 and the under surface 5a of the min hand 5 are brought to the same polarity while the upper surface 5b of the min hand 5 and the under surface 3a of the sec hand 3 are brought to the same polarity. Repulsive force is acted between the set type 10 and the min hand 5 as well as the min hand 5 and the sec hand 3 and, even if play is generated in the attachment of the hands, said hands are not contacted and erroneous operation is prevented while the wristwatch can be made thin. |
