Born from Schaumburg Watch’s dedication to robust, heirloom-grade tool watches, this model was conceived for serious divers and explorers who demanded durability and precision. Hand-built in Rinteln with Swiss mechanical heartbeats, early examples like serial 907 combined German case-making with Swiss movements to create a watch that favored function over fashion. Over the years it proved its mettle on expeditions and daily wear alike, evolving in straps and surface wear but remaining steadfast in purpose: a purpose-built diver’s instrument meant to be used, not coddled.
