摘要:
A second hand correction device comprising a second hand correction member which may be moved manually in inward and outward directions and in forward rotation and reverse rotation directions and a cam wheel, having a plurality of cams, which is fixed to the second hand axis. The second hand correction member is moved in such a direction as biased under an engagement with the cam wheel when the same is lowered, and engages with the cam at the rear half of its stroke. Subsequent lowering operation of the second hand correction member will cause the rotation of the cam wheel and thereby the second hand will be rotated by a specified angle to enable a repetitive continuous correction for the second hand.
