Abstract

Le mécanisme de chronographe comportant, une roue de chronographe (2) solidaire d'un coeur de chronographe (3), une roue de compteur de minutes (4) portant un coeur de minutes (5) et coopérant avec un sautoir de compteur (34), ainsi qu'un marteau des secondes (21) et un marteau des minutes (6) coopérant avec les coeurs (3, 5) correspondant; qui se distingue par le fait que les marteaux des secondes (21) et des minutes (6) sont pivotés coaxialement indépendamment l'un de l'autre et soumis chacun individuellement à un ressort de marteau des secondes (28) respectivement à un ressort de marteau des minutes (14) tendant à les faire pivoter en direction de leur coeur (3, 5) respectifs; et qu'un organe de liaison (29) relie le marteau des minutes (6) au marteau des secondes (21) tout en permettant à ceux-ci de se déplacer angulairement l'un par rapport à l'autre d'une valeur préétablie, le tout agencé de sorte qu'en position de remise à zéro effectuée lesdits marteaux (6, 21) soient tous deux en contact avec la base de leur coeur (3, 5) respectif. Le sautoir de compteur de minutes (34) est pivoté sur un support (35) déplaçable angulairement concentriquement à la roue de compteur de minutes (4); une vis (36) permettant d'immobiliser ce support (35) dans une position désirée.
