 der letzteren die Anker in der jeweiligen Lage festgehalten werden. 



   Bei bekannten derartigen Einrichtungen ist man infolge der Anordnung der Elektromagnete gezwungen, die Anker in beträchtlicher Entfernung voneinander auf der Antriebswelle für das   Zeigerwerk zu   befestigen. Das hat zur Folge, dass durch die auf die Anker ausgeübten   magnetischen   Kräfte leicht ein Verdrehen der Triebwelle und damit eine unsichere Zeigereinstellung eintreten kann. 



   Gemäss der vorliegenden Neuerung sind die   Elektromagnete zweckmässig   parallel mit der Antriebswelle verlaufend angeordnet, so dass die. einander   zugekehrten   mit entsprechend ausgebildeten Polschuhen versehenen Enden dieser Elektromagnete gestatten, die Anker der Magnet-   H'8tellle mögliehst   nahe aneinander gerückt zwischen den Elektromagnetenden auf der Antriel) swelle für das Zeigerwerk befestigen zu können. 



   Durch diese Anordnung der Elektromagnete und Anker wird ein   äusserst   sicheres Einstellen der Zeiger erzielt. 



   Diese Sicherheit kann dadurch noch erhöht werden, dass die Anker aus einem einzigen   Stuck Eisen herausgearbeitet   sind, so dass sie in Bezug auf die Beanspruchung der Antriebswelle

   Ausserdem wird durch die Neuerung noch eine sehr günstige Wirkung der Magnetisierung auf die Anker erzielt, so dass auch bei stark auf die Uhr auftretenden Stössen, wie es bei Schiffen   der Fall ist,   ein sicheres Festhalten der Anker bewirkt und damit ein Schwanken der Zeiger vermieden wird, was bei den bekannte Einrichtungen nicht der Fall ist. 



   In der Zeichnung ist eine nach der Neuerung ausgebildete Uhr abgebildet und zwar zeigt

 of the latter the anchors are held in place.



   In known devices of this type, due to the arrangement of the electromagnets, the armature must be fixed at a considerable distance from one another on the drive shaft for the pointer mechanism. The consequence of this is that the magnetic forces exerted on the armature can easily twist the drive shaft and thus cause an unsafe pointer setting.



   According to the present innovation, the electromagnets are expediently arranged running parallel to the drive shaft, so that the. The ends of these electromagnets facing each other and provided with appropriately designed pole pieces allow the armatures of the magnet holders to be moved as close as possible to each other between the electromagnet ends on the drive shaft for the pointer mechanism.



   This arrangement of the electromagnets and armature ensures extremely reliable setting of the pointer.



   This security can be increased by the fact that the anchors are carved out of a single piece of iron so that they can withstand the stress on the drive shaft

   In addition, the innovation has a very favorable effect of magnetization on the armature, so that even in the event of strong impacts on the watch, as is the case with ships, the armature is held securely and thus the hands are prevented from fluctuating which is not the case with the known facilities.



   In the drawing, a watch designed according to the innovation is shown and shows
