IWC Portuguese Automatic 5000-04 Luxury Watch Review 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 1-of-750 Portuguese Automatic 5000-04, IWC combines its legendary 42mm "Portuguese" case with an in-house Cal. 5000 movement and 18-karat rose gold. As the debut platform for this 21st Century movement, the landmark IWC Portuguese 50000 also became the first automatic non-chronograph “Portugieser” since the model’s 1939 launch. 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 5000-04 benefits from the circa-Y2K arrival of the Schaffhausen firm's in-house caliber 5000. Designed and constructed entirely by IWC, the movement boasts a 7-day power reserve and IWC's famous mid-century "Pellaton" automatic 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. Additional refinements to the 18,000 VpH caliber include a Breguet overcoil hairspring for isochronism in multiple positions and a robust screw-fixed regulator inspired by IWC’s traditional pocket watches. A sapphire display caseback enables unobstructed enjoyment of this sprawling movement’s outstanding finish. As the world’s largest automatic movement, there’s plenty to for watch enthusiasts to appreciate. Finally, the impressive luster and weight of the 18-karat rose 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 5000 in 18-karat rose gold is impressively solid: think vintage Mercedes-Benz.
