Official description
A. Lange & Söhne is enriching its 1815 model family with a timepiece featuring one of the most sophisticated horological complications: The chronograph rattrapante. The new model is fully focused on the eponymous complication, and it is endowed with a custom- developed movement. It not only delivers the foundation for a totally unique dial design but also stands for the drive that allows the Saxon manufactory to go its own way. The 1815 RATTRAPANTE has a platinum case and comes in a limited edition of 200 pieces.
