Julius Assmann To celebrate the 175th birthday of one of Germany?s most significant watchmakers, Glashütte Original introduced the ?Julius Assmann 3? tourbillon watch in 2002. Born in Stettin on Oct. 2, 1827, young Julius learned watchmaking and then moved to Berlin, from where he journeyed to Glashütte in 1850 to perfect his craft. At the time, the industry in the small struggling town in Saxony?s Müglitz valley was just 5 years old and Assmann found employment with Ferdinand Adolph Lange, who had started the trade to improve the economical situation in the area. After 2 years, Julius founded his own business, the ?Julius Assmann Deutsche Präzisions- Taschenuhren Fabrik?, buying most of his supplies locally, while assembly and sales of key-wound pocket watches were done in his factory. Already in 1854, his young company exhibited in the German Trade and Industry exposition, winning a prestigious gold medal. The Prussian government asked him to start a watch industry in Silesia and Brandenburg, but Assmann declined, preferring to jointly start the ?Deutsche Uhrmacherschule? (German School of Watchmaking) in Glashütte in 1877, becoming its board?s chairman in 1885, a great honor for the businessman and master of his craft.
