Jumper device (80) for a timepiece device (100) including at least one first arm (81) including a first beak (81a) for positioning a first mobile unit (10), at least one second arm (82) including a second beak (82a) for positioning a second mobile unit (20), an elastic element (84) for returning the first arm and the second arm to configurations positioning the first and second mobile units, and a lever (83; 83′) interfaced between, on the one hand, the elastic return element, and on the other hand, the first and second arms.

An adjustable timepiece assembly, including a base bar and an adjustable bar whose position is adjustable with respect to the base bar, parallel to a reference plane, the adjustable assembly includes a first part guided in rotation on a first pin integral with the base bar and which includes a first toothed sector meshing with a first adjustment pinion press fit in the base bar, and which is subjected to the return force exerted by a first return spring to take up play, and the adjustable bar is guided in rotation on a second pin integral with the first part, and includes a second toothed sector meshing with a second adjustment pinion press fit in the first part, the adjustable bar being subjected to the return force of a second return spring.

A timepiece capable of selecting a timepiece mode and a chronograph mode includes an hour hand and a minute hand which indicate current time in a case where the timepiece mode is, selected. A main control unit performs control so as to start measuring time by simultaneously starting hand operations of the hour hand and the minute hand in a case where the chronograph mode is selected. When the hand operation of one of the hands is stopped, the control unit performs control so as to indicate the time when the hand operation of the one hand is stopped, and to continue to measure the time by continuing the hand operation of the other hand.
