By the late 19th century, precise timekeepers from Glashütte had already achieved a global reputation for the certain determination of one’s position at sea and on land. Along with marine chronometers, these so-called “observation watches” soon became essential navigational instruments for naval officers, pilots and explorers such as Roald Amundsen.

Observation watches were traditionally fitted with manual winding movements. Today a state-of-the-art automatic movement ensures maximum comfort for the wearer. The Senator Observer features an exquisitely finished movement with a power reserve of 55 hours.
