http://www.thewatchbox.com IWC of Schaffhausen, Switzerland is the foremost German-Swiss watchmaker. Founded by an American in 1868 and based far from the western Swiss "Watch Valley," IWC has a history of going its own way. In the Portuguese Automatic 5001.06, IWC combines its legendary 42mm "Portuguese" case with an in-house 50000 series movement and 18-karat white gold. Designed in 1939 at the behest of its Portuguese market import managers, the "Portugieser" model, as it is known in German, was considered a monster. Engineered specifically to house a pocket watch movement (seen as essential to achieve accuracy in those days), the watch was over 33% larger than the typical men's watch of the period. It was considered a monster at the time, but history has vindicated its unconventional style and elevated the Portuguese to icon status. In an age that reveres large watches and considers sub-40mm cases downright dainty, the Portuguese is a style leader. Within the famous case, IWC's modern day Portuguese 5001.06 benefits from the refinement of the Schaffhausen firm's in-house caliber 51011. Designed and constructed entirely by IWC, the movement boasts a 7-day power reserve and IWC's famous mid-century "Pellaton" winding system. One of Swiss industry's few stellar alternatives to the Rolex reversing wheels, the Pellaton system often has been imitated but never duplicated. Finally, the impressive luster and weight of the 18-karat white gold case creates a true premium ownership experience. In the hand or on the wrist, the mass of this watch provides constant assurance of its substance and refinement. While not excessively heavy, the Portuguese Automatic in 18-karat white gold is impressively solid: think vintage Mercedes-Benz. This IWC Portuguese Automatic 5001.06 is available from thewatchbox.com with full factory boxes, papers, manuals, and accessories. It presents as new and offers an outstanding point of entry into one of the industry's most celebrated model lines. Video and content by Tim Mosso.
