Unworn IWC Portugieser Automatic Chronograph, Stainless steel, 41 mm, Ref# IW371606, box and papers

Introducing the unworn IWC Portugieser Automatic Chronograph, Ref# IW371606—a striking reinterpretation of one of Schaffhausen’s most iconic timepieces. Designed to honor the brand’s heritage of nautical precision, this 41mm chronograph embodies timeless elegance fused with technical prowess. The brushed and polished stainless steel case, with a round 13mm thickness, offers a refined yet sporty silhouette. Its blue dial, adorned with a fine sunray finish, radiates depth and sophistication. The design is accentuated by rhodium-plated feuille hands and applied Arabic numeral hour markers, while a subtle silvered dot minute/seconds track runs around the periphery for balanced symmetry. A hallmark of this model is the fractions-of-a-second track printed along the inner flange—also known as the réhaut—featuring a quarter-second scale for precision timekeeping. This not only emphasizes the chronograph’s functionality but also echoes the Portugieser’s legacy as a seafaring instrument of accuracy. Chronograph features include a large central seconds counter hand, a 30-minute counter at 12 o’clock, and a small seconds sub-dial at 6 o’clock, delivering both balance and clarity. At the heart of the watch is the IWC-manufactured caliber 69355, a robust automatic movement composed of 194 components, beating at 28,800 vph, with 27 jewels and a 46-hour power reserve. The transparent sapphire case back reveals this high-performance mechanism in motion. Completing the look is a luxurious black alligator leather strap, secured with a deployant buckle clasp for all-day comfort and elegance. With water resistance up to 30 meters (100 feet) and its subtly thin bezel, the watch wears larger than its size suggests, making a bold yet tasteful statement on any wrist. This Portugieser Automatic Chronograph is more than a timepiece—it’s a legacy of precision, style, and craftsmanship born from the world of maritime navigation.
