Abstract
A mechanism for driving an indicator for a timepiece includes: a mobile for driving the indicator; a first lever mounted about a first pivot and including a beak to cooperate with a toothing of the mobile; a first cam arranged to rotate the first lever about the first pivot; a second lever mounted about a second pivot and to which the first pivot is rigidly connected; a second cam arranged to rotate the second lever about the second pivot; and elastic elements for maintaining the cooperation between the levers and cams; the levers and the cams being arranged so that the beak of the first lever cyclically describes a closed curve, each cycle including a first motion during which the beak leaves the toothing of the mobile without changing the angular position thereof and a second motion during which the beak re-enters the toothing to move the mobile.
