A chronograph wheel (4) includes a mobile wheel (4a) with an end connected with the kinematic chain by an intermediate of an engaging mechanism and another end directly connected with the mainspring. A connection between another mobile wheel (4f) of the chronograph wheel and the kinematic chain comprises an escape wheel (2) of the chronograph integrated with a mobile of the kinematic chain. An engaging mechanism is associated with a brake unit.
