A **double rattrapante** is a [[chronograph]] with an extension of the usual [[rattrapante]] function.

With [[rattrapante]] [[chronograph]]s split time measurements, time comparisons, as well as minimum and maximum time value measurements can be performed, in addition to the usual functions of [[chronograph]]s.

But in conventional rattrapante chronographs these functions are limited to the seconds scale, ie exactly 60 seconds. The **double rattrapante mechanism**, developed by [[A. Lange & Söhne]] and presented with the model [[A. Lange & Söhne Double Split|Double Split]], is also equipped with a counter of flyback minutes. With this, it is now possible to use to the flyback functions up to a period of 30 minutes - and thus really useful.
