Timepiece with an activating mechanism
First Claim
1. A timepiece comprising a movement and an activating mechanism operatively connected to said movement for producing, at a presettable time, the closing of an electrical contact, the time-piece comprising:
- a framework;
a first contact member of a first material;
a first support rotatably mounted on said framework and rotationally coupled to said movement, for carrying said first contact member;
a second contact member of a second material;
a second support mounted on said framework, in a position which is rotationally adjustable about the axis of rotation of said first support, for carrying said second contact member, said second contact member being located at substantially the same distance from said axis of rotation as said first contact member; and
said first and second materials being chosen to comprise magnetic coupling means for bringing said first and second contact members into contact when they have been rotated with said supports into positions opposite each other.

Abstract
The alarm wheel (5) is mounted with axial clearance between an insulating plate (6) and a wheel (8).
This wheel (5) is in mesh with the hour cannon wheel (3). It has an embossment (5a) which, once during each turn, passes in front of a magnet (9) carried by the plate (6). The wheel (5) is then attracted axially and its embossment (5a) enters into contact with the magnet (9), grounding the latter. Now, the magnet (9) being in permanent contact with one of the conductive tracks (13) of the printed circuit of the watch, this track (13) is thus grounded. The user of the watch can alter the time at which the releases are produced by altering the angular position of the plate (6). No spring acts axially on the alarm wheel (5) which moves freely between the wheel (8) and an annular rib (6e) provided on the plate 6.
