A. Lange & Söhne Double Split
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 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.
In the same year this model won the Special Prize of the Jury at the prestigious Grand Prix d'Horlogerie de Genève.
