Glashütte is a small town in the Müglitz valley in eastern Saxony, about 25 km south of Dresden. Ferdinand Adolph Lange founded a watchmaking school and a workshop here in 1845, on a state subsidy meant to relieve local mining poverty after the silver veins ran out. The town became the German watchmaking capital before WWII; the post-war GDR consolidated the surviving makers into VEB Glashütter Uhrenbetriebe; reunification in 1990 reopened the trade. The modern manufactures. Lange, Glashütte Original, Nomos, Tutima, Mühle, Moritz Grossmann, sit within a two-kilometre radius of each other on the same valley floor.
