Honey gold was used for the case of this limited edition watch, of which A. Lange & Söhne has manufactured only 50 units. The watch has a one-minute tourbillion as well as a double chronograph. The Tourbograph "Pour le Mérite" can be purchased in New York City, Dresden, Shanghai, and Tokyo. Like Glashütte Original, the company is based in the former East Germany. After the Soviet occupation, the region’s once-thriving watchmaking industry foundered. Lange, which had been founded in 1845, shut down and was revived in 1990. Today it is part of the Richemont Group.
