IWC Schaffhausen IWC Portugieser 'Eight Days' 75th Anniversary - (Ref. IW510205) Product Details

Overall Condition: Excellent condition overall. Case shows light wear. Dial and matching handset are as-new.

The Portugieser exists because someone asked IWC to do the impossible.

In the late 1930s, two clients from Portugal approached IWC Schaffhausen with a challenge: build a wristwatch with the accuracy of a marine chronometer. At the time, that meant one thing—scale. IWC’s solution was to house a pocket-watch movement inside a wristwatch case, creating something radically oversized for its time. When the original debuted in 1939, its proportions were shocking, its clarity unmatched. It didn’t follow the rules—it quietly rewrote them.

Fast forward to 2015, and the Reference 5102 arrives as a 75th anniversary tribute to that original idea. At 43mm, it remains faithful to the Portugieser’s defining trait: presence with purpose. But what keeps it from feeling oversized is the balance—the wide, open dial, the slim bezel, the long, elegant lugs.

The graphic black dial is particularly striking. Printed 'Arabic' numerals anchor the design, while a subsidiary seconds at 6 o’clock reinforces the symmetry. Flip it over, and the real story reveals itself: the hand-wound Caliber 59215, visible through an exhibition caseback, delivering a remarkable 8-day power reserve. It’s mechanical watchmaking at its most satisfying—wind it once, and let it breathe for the better part of a week.

Limited to just 750 pieces in stainless steel, this is a Portugieser that feels both reverent and modern—true to its origins, but entirely at ease today. Sometimes the boldest move is simply making something bigger—and getting everything else exactly right.
