An exceptionally well-preserved ref. 1812 Aquatimer, the first IWC dive watch. It sports a 37mm Piquerez case with dual fish crowns, vivid honey tritium, applied IWC logo, and Pellaton winding system (including tropical strap with IWC pin buckle and Gary Frères IWC bracelet). Fewer than 2,000 examples are thought to have been made over its 25 year production. A perfect dive watch equally for those who deeply know their IWC history or who have an eye for Bauhaus, utilitarian design.
