Abstract

A rocker (5) actuated by a pin (4) solid with a twenty-four hour wheel (3) pivots about a spindle (20) and enables the date to be changed using a roller (7) provided with a catch (8) capable of meshing with the calendar disc (9). A lever (14), pivoting on the spindle of the twenty-four hour wheel, has one of its ends (14a) fitted between two consecutive teeth of the calendar disc whilst its other end (14b) carries a pin (16) fitted in an oblong entrance (17) to the rocker. When the date is changed, the pivoting of the rocker rotates the lever (14) in the anti-clockwise direction, so that its end (14a) frees the calendar disc. Outside of the area for changing the date, the rocker is arrested by a pin (18) solid with it and fitted into a circular track (19) of constant width cut into the twenty-four hour wheel. <IMAGE>
