Lange & Sohne

A. Lange & SohneA. Lange & Sohne is a trademark of German watchmaking company Lange Uhren GmbH ("Lange"), a subsidiary of Richemont SA. Lange pocket and wrist watches are among the finest in the world, competing with watches produced by Swiss firms such as Patek Philippe and Vacheron Constantin.
All Lange and Sohne watches contain mechanical rather than quartz movements and, with the exception of a very few special edition watches, Lange watch cases are made of gold or platinum. Lange movements are developed, produced, and assembled by Lange itself. Lange's movement design and decoration is distinctively Glashütte in appearance, eschewing typically Swiss features, such as multiple bridges and cocks, or Geneva wave decoration, in favor of three-quarter plates, "Glashütte stripes", hand-engraved balance cocks and screwed gold chatons. Lange movements are made from a metal known as "German silver", an alloy of copper and nickel, as opposed to the plated brass typically used for Swiss movements, giving Lange movements an unusual color and sheen.
