Seneta Observer.

By the late 19th century, Glashütte's precision watches had already gained a worldwide reputation as reliable locators of position at sea and on land. Along with marine chronometers, so-called "observation watches" became indispensable nautical instruments for naval officers and crews, as well as for explorers such as Roald Amundsen.
Functional design and perfect legibility were essential for observation watches. The clearly arranged displays power reserve, small seconds, panoramic date, and large arabic numerals are decisive for the overall impression.
Observation watches have traditionally been equipped with hand-wound movements. Today, state-of-the-art automatic movements ensure maximum comfort for the wearer. The Senator Observer is equipped with a neatly finished movement with a power reserve of 55 hours.
