Glashütte Original pays homage to the pioneering spirit of two extraordinary men, Julius Assmann, who became famous as one of the pioneering spearheads of watchmaking in Glashütte, and Roald Amundsen, the legendary Norwegian South Pole explorer, who was also known to be fond of and rely on the precision of the Glashütte observation watches in his missions. The Senator Observer 1911 Julius Assmann exhibits the exclusive, understated presence a Glashütte Original is famous for as also the utterly delicate innards. The self-winding automatic caliber 100-14 beeps in the inside, visible through a sapphire case back, that also opens the view for the famous gold-plated double-G mark. On the dial shine subsidiary seconds, power reserve displays and a signature panorama date display.
