Abstract

La présente invention a pour objet un dispositif de commande (20) pour pièce d’horlogerie (10) comprenant une tige de commande (22) qui est équipée d’une couronne (24) amovible, le dispositif de commande (20) comportant un dispositif de verrouillage (26) permettant, en position verrouillée, de solidariser la couronne (24) avec la tige de commande (22) et, en position déverrouillée, de désolidariser la couronne (24) de la tige de commande (22), caractérisé en ce que la couronne (24) comporte une coiffe (28) et un corps tubulaire principal (30) qui est fixé à la coiffe (28), en ce que le dispositif de verrouillage (26) comporte une bague extérieure (36) qui, en position verrouillée, bloque axialement la couronne (24) sur la tige de commande (22) et, en position déverrouillée, libère la couronne (24) par rapport à la tige de commande (22). Figure pour l'abrégé : 3The subject of the present invention is a control device (20) for a timepiece (10) comprising a control rod (22) which is equipped with a removable crown (24), the control device (20) comprising a locking device (26) making it possible, in the locked position, to secure the crown (24) to the control rod (22) and, in the unlocked position, to separate the crown (24) from the control rod (22), characterized in that the crown (24) comprises a cap (28) and a main tubular body (30) which is fixed to the cap (28), in that the locking device (26) comprises an outer ring (36) which , in the locked position, axially locks the crown (24) on the control rod (22) and, in the unlocked position, releases the crown (24) relative to the control rod (22).
