A. Lange & Söhne is a German luxury watch brand founded in 1845 by Ferdinand Adolph Lange in Glashütte, Saxony. After an interruption caused by World War II and the subsequent Soviet occupation, the brand was relaunched in 1990 through the efforts of Walter Lange, great-grandson of the founder, and other watchmakers. Today, A. Lange & Söhne is one of the world's most respected luxury watch brands, known for its craftsmanship, precision, and elegant design. Among its iconic watches are the Lange 1, Zeitwerk, Saxonia, and Datograph. A. Lange & Söhne is part of the Richemont luxury group.
