Abstract

The watch comprises a stone (13) driven into the rotor bridge (11). This stone has a circular aperture (13') in which the cylindrical part (12') of the pivot (12) for the shaft of the rotor pivots. The aperture (13') terminates on the inside in a wide cone (15) serving as guide for the end of the pivot (12) during installation of the rotor bridge (11) carrying the stone (13), and does so even if the rotor is inclined through magnetic attraction between its magnet (5) and the stator (2, 2') of the micromotor. <IMAGE>
