<p>The watch has a main force storage i.e. barrel, through which a retensioning element is drivably and rotatably guided in cyclic intervals at a retensioning axis by a retensioning controller, via a gear train. A storage coil spring (6) is retensioned by the storage, which has an end connected with the element. The spring has another end connected with a wheel that rotatably drives a clock mechanism. The wheel is in contact with a train of an escapement. An interval switchable device i.e. minute hand drive, is drivable and rotatable in cyclic intervals by an element of the gear train.</p> |
