Wenn die Federn 6 und 7 aufgezogen sind, so suchen sie vermöge ihrer rückwirkenden Kraft bei dem allmählichen Entspannen, was ein ganzes Jahr oder länger andauern mag, das Zahnrad 10 beständig und regelmässig in einer Richtung zu drehen. Dadurch wird die Feder 25 auf ihrer ganzen Länge von einem Ende des Kernes zum anderen gespannt, und zwar soweit, als es ihre Berührung mit der Kernerweiterung 23 zulässt, und während das Aufziehen an dem dem Zahnrade 10 benachbarten Ende der Feder fortgesetzt wird, überwindet die nach dem anderen Ende zu vorhandene Spannung den Widerstand des Uhrwerkes und treibt dasselbe an, wobei ein ent-

When the springs 6 and 7 are wound up, they seek, by virtue of their retroactive force in the gradual relaxation, which may last a whole year or more, to turn the gear wheel 10 constantly and regularly in one direction. As a result, the spring 25 is stretched over its entire length from one end of the core to the other, to the extent that it allows its contact with the core extension 23, and while the winding is continued on the end of the spring adjacent to the toothed wheel 10, the at the other end of the existing voltage increases the resistance of the clockwork and drives it, whereby a

is unwound and drives the clockwork, and the extension 23 reduces that force of the spring motor, which is available in excess of that required to drive the clockwork.
by limiting the tensioning of the spring 20 to the amount necessary to do the work.
Instead of the motor with two spiral springs acting on the gearwheel 70, such a

PATENT CLAIMS:
1st watch with a long running time. characterized by a helical spring (2J) connected between the motor and the drive and a rigid core (20) provided with a thickening (23), which allows the spring to be tensioned automatically by the force of the motor only as much as to drive the drive is required.
