Unworn IWC Portugieser Automatic Chronograph, Stainless steel, 41 mm, Ref# IW371620, box and papers

Introducing the unworn IWC Portugieser Automatic Chronograph, Ref# IW371620—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. The silver-plated dial creates a timeless base for the watch's elegant details, embodying the discreet luxury typical of classic watchmaking. The design is accentuated by blued stainless steel feuille hands and applied blued stainless steel Arabic numeral hour markers, while a subtle blued stainless steel 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 contrasting blue 30-minute counter at 12 o’clock, and a contrasting blue 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. Additionally, this elegant sports watch features a versatile blue rubber strap that combines durability with contemporary style. Designed for an active lifestyle, the strap provides a secure and comfortable fit thanks to its flexible design and classic clasp, allowing you to wear the watch all day long and giving it a sleek, sporty look. 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.
