Abstract
A display device that prevents display jumping and corrects the display that includes a displaying transmission wheel which is meshed with a drive wheel and a displaying follower wheel is pressed by a spring toward the area between the drive wheel and the displaying follower wheel so as to elastically take up the play between the drive wheel and the displaying follower wheel. During feeding, the displaying follower wheel is positioned by the displaying transmission wheel. If a crown is pulled out and rotated, the displaying follower wheel is rapid-fed and corrects the display without the aid of the drive wheel and the displaying transmission wheel. At the same time, however, the displaying transmission wheel receives a force in the direction in which it is pressed out of a gap, whereby the engagement with the displaying follower wheel is released.
