Originally founded in 1845 by Ferdinand Adolph Lange in Glashütte, Dresden, Germany, the firm established an entire watchmaking culture and industry in Glashütte. The brand quickly became Germany's finest watchmaker, first creating dependable, easy-to-repair watches before going on to produce some of the world's finest complicated pocket watches, including Grande Sonnerie watches, tourbillon watches and Grande Complications.
On the final day of World War II, their factories were destroyed by Russian bombers, and in 1948 the brand was confiscated by the Soviet Union. Following the fall of the Berlin Wall in 1990, Ferdinand's great grandson Walter Lange re-established the brand with the objective to once again produce top-quality luxury watches. Now part of the Richemont Group, its original vintage and modern creations are highly coveted by collectors.
