Again and again, the calibre engineers at A. Lange & Söhne have succeeded in enriching the art of horology with spectacular complications. One of them is the rattrapante minute counter of the DOUBLE SPLIT. For the first time in the history of mechanical wristwatches, it can perform comparative time measurements that last as long as 30 minutes.

Until the DOUBLE SPLIT emerged, the French term rattrapante merely designated the ability of a split-seconds chronograph’s superposed seconds hand to “catch up” with the main sweep seconds hand. Comparative time measurements were limited to 60 seconds, and could not always be used in a relevant way.

Lange’s designers questioned the underlying concept of the rattrapante function, thought it through to its logical conclusion, and then devised the rattrapante minute counter as a truly useful innovation. Complications of this kind are never introduced for the sake of novelty: they must deliver a genuine user benefit.
