{{wst>image_cr|Lange|L001.1|Calibre Lange L001.1}}

The calibre **Lange L001.1** by [[A. Lange & Söhne]] is installed in the [[A. Lange & Söhne Double Split]]. It is based on the calibre [[Lange L951|L951.1]].

In addition to the [[rattrapante]] mechanism with the characteristic rattrapante pliers, for the first time a sophisticated lever system is used, which transmits the rattrapante function also to the minutes counter-axle. Only partially visible below, the [[chronograph]], the [[flyback]] and the minutes counter mechanism are arranged. To minimize mechanical friction at the stopped rattrapante hands but still running [[chronograph]], an insulator mechanism is used, which was newly developed by Lange and registered as patent.

The [[plate]]s and [[bridge]]s in untreated [[German silver]] are decorated with [[perlage]] and [[Glashütte Stripes]], all edges are [[angled]] and polished. Likewise, the swan's neck spring and the two classical column shift gears.
