Abstract

La présente invention concerne un mouvement horloger (1) à fonction compte à rebours comportant un compteur de chronographe des minutes (44), destiné à entraîner un organe d'affichage des minutes (8) d'un temps mesuré, un mobile d'affichage (20) d'un organe d'affichage (14) des minutes à décompter, et un organe de commande (46) agencé pour agir sur le mobile d'affichage (20) et régler l'affichage du nombre de minutes à décompter. Ce mouvement horloger comporte un mobile d'entraînement (22) présentant une première liaison cinématique avec le compteur de chronographe des minutes (44) et une seconde liaison cinématique (30) avec le mobile d'affichage (20), les première et seconde liaisons cinématiques étant agencées de telle manière que le mobile d'entraînement est susceptible d'entraîner le mobile d'affichage (20) en rotation à partir des mouvements du compteur de chronographe des minutes (44). L'une des liaisons cinématiques présente un mécanisme de débrayage (30, 32) agencé de telle manière que le compteur de chronographe des minutes (44) reste immobile lorsque l'organe de commande (46) est actionné, et que le mobile d'affichage (20) reste immobile lorsque le nombre de minutes à décompter est nul quand bien même la mesure d'un temps est en cours.

The present invention relates to a countdown timer movement (1) having a minute chronograph counter (44) for driving a minute display member (8) of a measured time, a display mobile (20) a display member (14) minutes to be counted, and a control member (46) arranged to act on the display mobile (20) and set the display of the number of minutes to count down. This watch movement comprises a driving wheel (22) having a first kinematic link with the minute chronograph counter (44) and a second kinematic link (30) with the display wheel (20), the first and second links. kinematics being arranged in such a way that the driving wheel is able to drive the display unit (20) in rotation from the movements of the minute chronograph counter (44). One of the kinematic links has a disengaging mechanism (30, 32) arranged such that the minute chronograph counter (44) remains stationary when the control member (46) is actuated, and the mobile display (20) remains stationary when the number of minutes to be counted is zero even though the measurement of a time is in progress.
