Abstract

The chronograph watch comprises at B the spindle of a seconds counter and at C the spindle of a minutes counter. The link between the seconds runner and that for the minutes is produced by a cam (H) located on the spindle B controlling, by means of a fork (I), the displacement in rotation of a rocker (J) about a spindle (K). The end of the rocker (J) comprises a ratchet blade (M) driving the toothing of a wheel (N) integral with the spindle C of the minutes counter. A mechanism of this type is simple to construct and does not interfere with the chronograph mechanism. <IMAGE>
