The TOURBOGRAPH „Pour le Mérite“ in a case made of the new, harder gold.

In 2005, A. Lange & Söhne presented a grand complication that established a new benchmark in precision watchmaking: the TOURBOGRAPH „Pour le Mérite“. It was the first one-minute tourbillon in a wristwatch format with a fusée-and-chain transmission as well as an additional rattrapante chronograph. Because of the complexity of the mechanism, it was possible to craft only one watch per month, so the last timepiece of the first partial edition of 51 platinum models was only just delivered a few weeks ago. The coming of a second partial edition of 50 watches in a yet-to-be-defined gold version was announced on the occasion of the original debut. The TOURBOGRAPH “Pour le Mérite” which is now being presented in honour of Ferdinand Adolph Lange also has a case made of the new, harder gold. And it, too, embodies Lange’s ambition to build the world’s finest watches. At the same time, it proves that even a horological superlative can be taken to a new, higher level.
