Glashütte Original is known for their exceptional mechanical observation watches, a tradition they take great pride in. In 2012, they introduced the Senator Observer 1911 in white gold, a limited edition dedicated to Julius Assmann and Roald Amundsen. Later that year at Baselworld, they also unveiled a stainless steel version with a sleek silver-grained dial. Assmann's precision and reliability in creating handmade observation watches made them essential for navigators, pilots, and explorers like Amundsen. He was so impressed with a pocket watch made by Assmann that he purchased it and took it with him on his historic journey to the South Pole. The different references of the Senator Observer 1911 come with various strap options
