A. Lange & Söhne watches was revived by the founder's great-grandson Walter Lange, after the collapse of the Soviet Union and the reunification of Germany. The first Lange 1 watch helped reboot the brand after a 50-year hiatus, and A. Lange & Söhne continues to make its mark today with high-quality luxury watches. It is regarded as one of the best high-end watch manufacturers in the world.
