With a design that is as crisp as it is timelessly modern, the IWC Schaffhausen Portugieser has become an icon of watchmaking. The history of this iconic timepiece dates back to 1939, when two Portuguese merchants commissioned IWC to produce highly accurate wristwatches. In the decades since, the IWC Schaffhausen Portugieser family has continued to expand in popularity. With modern watchmaking techniques.
