Ferdinand Adolph Lange founded A. Lange & Söhne in 1845 to make pocket watches. They were based in the small town of Glashütte, Germany. Over the years, the master watchmaker established a watch industry in the Ore Mountains modeled after the Swiss industry. After the Second World War, A. Lange & Söhne ceased to be an independent company. German reunification in 1990 gave A. Lange & Söhne the chance to reestablish themselves. Walter Lange, great-grandson of Ferdinand Adolph Lange and also a master watchmaker, founded Lange Uhren GmbH in December 1990. Four years later, the company presented their first collection consisting of four wristwatches: the legendary Lange 1, the Saxonia, the Arkade, and a model featuring a tourbillon, the Pour le Mérite.
A. Lange & Söhne watches and in-house calibers are on the same level as those from the Swiss companies Patek Philippe or Vacheron Constantin. Unlike these two brands, however, A. Lange exclusively uses precious metals like gold or platinum for their cases. There are only a few stainless steel versions of the Lange 1 from the 1990s. Since they're so rare, they can sell for over $100,000 at auctions. One characteristic of A. Lange & Söhne watches is the outsize date, which was patented in 1992. A. Lange & Söhne watches are also characterized by their blued screws, Glashütter sunburst design, a swan-neck fine adjustment, a three-quarter plate (invented by Ferdinand Adolph Lange), and a finely engraved balance cock.
Manual wind movement with perpetual calendar as well as classic chronograph and rattrapante functions. 42 hours of power reserve.
