I assume one no "nuts" about this brand.
Therefore extract from the net:
" The manufacture was established in the small town of Rinteln, which is a centuries old village in Lower Saxony region of Germany. They are focused on creating unique and desirable watches. Schaumburg Watch are widely gaining international popularity with recent expansions and adopting worldwide partners to distribute their watches.
For many years, the company has had only one objective - to produce outstanding quality watches manufactured in smaller quantities in order to retain a focus on quality rather than quantity in production. Schaumburg Watch are widely recognised as manufacturers of watches which pay particular attention to detail and are pay particular focus towards design.
The net result of these two attributes means the watches are split into main series - the classic line including the Squarematic, Ellomatic, and Classoco models and the professional divers series including the Aquamatic, Aquamatic COSC, and Aquamatic Professional Chronograph. Each watch is designed in house, down to the smallest details of the very unique cases. The Classic watches are every bit as classic as the name suggests and are designed like no other watch, they are unique in every way. The professional series are strong durable and substantial watches, manufactured to exacting standards and are every bit as strong as they look. "
