Stepping mechanism for digital timepiece

Serving to advance digital indicating means of a timepiece having a central drive element, the mechanism comprises a stationary peripheral series of teeth, a stepping finger, which is mounted to be rotatable and radially displaceable relative to said central drive element and engageable with said series of teeth and coupled to said digital indicating means for joint rotation, a one-way coupling element, which is eccentric with respect to and operatively connected to said central drive element to revolve around the same in a predetermined direction and arranged to repeatedly withdraw said stepping finger from said series of teeth after respective intervals of time, and spring means urging said stepping finger radially outwardly and in said predetermined direction of revolution, whereby said spring means are arranged to impart a rotation to said spring finger and digital indicating means in said predetermined direction of revolution when said stepping finger has thus been withdrawn and until said stepping finger reengages said series of teeth.
