Abstract
The zero resetting mechanism has a double hammer rocker device (1), each hammer arm (5, 6) cooperating with a respective heart-shaped zero resetting cam (9, 11) used for simultaneous resetting of the seconds and minutes hands. One of the hammer arms (6) is acted on by a displacement mechanism (13) using a cam (16) associated with a regulating element (15) rotated relative to the rocket device about an axis parallel to the pivot axis (2) of the latter. ADVANTAGE - Provides precise resetting of hands.
