Abstract: A chronograph includes a chronograph train, means for coupling the train and a device for controlling the coupling means, which includes: a pivotably mounted shuttle, a first angular sector provided with two notches defining first and second stable angular positions, and a second angular sector that includes cut out portions, an elastic member cooperating with the notches to keep the shuttle in one of the stable positions, and a push-piece cooperating with the cut out portions to pivot the shuttle, via a first application of pressure, from the first stable position to the second stable position, and via a second application of pressure, from the second stable position to a third intermediate angular position.
