A. Lange & Söhne is a German fine watchmaker based in Glashütte, Saxony, founded by Ferdinand Adolph Lange in 1845 and revived by his great-grandson Walter Lange in 1990. It produced only a few thousand watches per year, mainly in gold and platinum, including the LANGE 1, ZEITWERK, 1815 and DATOGRAPH, each with an in-house movement assembled twice by hand.
