Established in Glashütte, Saxony by Ferdinand Adolph Lange in 1845, A. Lange & Söhne produced some of the most sought-after watches in the world.
The company was forced into a 40 year hiatus when their workshops were destroyed by a bomb at the end of the Second World War. In 1990, Walter Lange, the great grandson of Ferdinand Adolph Lange, revived the brand.
Lange watches are still created in-house to the traditional high standards of the earlier generations of pocket watches. Today, as throughout their history, A. Lange & Söhne produce high quality precision timepieces.

This watch is a third generation reference 1815 chronograph dating from 2017
