The timepiece has a case (11) in which components such as clock movement (3), time setting system, chronograph mechanism (7) and display system (9), are mounted. The movement is adjusted using the system by manipulation of a crown projecting from the case. The mechanism is controlled by two push buttons (19, 21). The buttons respectively have anti-impact devices (33, 35) that are mounted in the case. The anti-impact devices decouple the buttons and the crown from the components of the case when a force greater than a preset threshold is exerted on the buttons and the crown. |
