Abstract

The calendar mechanism includes a ring (1) indicating the days of the month, with an internal toothed ring (22), and a uni-directional manual correction mechanism. An operating lever (3) pivots about an axis (5), and is subject to the action of a spring urging the lever against a stop (9). A finger (14) with a ramp surface (20) cooperates with a pin (21) carried on a 24 hour wheel (2). This is linked to the pivoting mechanism in order to advance the indicator wheel. (7pp Dwg.No.1/5)
