A timepiece having means for recording, or indicating, data of the date of the month and day of the week wherein such data is provided by indicia respectively inscribed on a rotating ring and a concentrically arranged rotating disk. A first shift finger extending through a rotatable guide casing is pivotally mounted on a fixed member in the timepiece, and engages means for drivingly advancing the disk. A second shift finger is mounted on the guide casing and engages the ring. The shift fingers are disposed in different planes to avoid contact by the first shift finger with driven teeth on the ring. Rotation of the guide casing serves to rotate the shift fingers, and hence the ring and disk. The first shift finger is mounted eccentrically with respect to the guide casing so as not to interfere with movement of the ring, and to permit a wide variety in the selection of the position of a driving element.
