A. Lange & Söhne is an independent company.

German haute horlogerie manufacture founded in 1845 by Ferdinand Adolph Lange in Glashütte, Saxony. The brand established Glashütte as a centre of fine German watchmaking before being nationalised under East Germany in 1948. It was re-established in 1990 by Walter Lange, Ferdinand Adolph Lange's great-grandson, following German reunification. A. Lange & Söhne relaunched in October 1994 with four landmark models including the Lange 1, and is now regarded as Germany's foremost luxury watchmaker. Richemont acquired A. Lange & Söhne in 2000 as part of its acquisition of Les Manufactures Horlogères.
