ABSTRACT:
The alarm arrangement is among those in which an alarm is released by the coincidence of a first contact point coupled to the going train of the timepiece with a second contact point coupled to an index the position of which may be regulated by a manual control element. In this arrangement the second contact point (68) is coupled to a member (60) fixed to a rotating shaft (58) on which are pivoted wheel sets (76, 92) of the going train which bear time indicating hands (82, 100). In a very simple case the member fixed to the rotating shaft is adjacent the timepiece hour wheel (80) and the contact points (68, 90) are borne by these two elements on their faces and facing one another. On the other hand the manual control element may be advantageously formed by the glass (16) of the timepiece which is then coupled to one of the ends of the rotating shaft and a rotatable bezel (22) to which the glass is fastened.
