About This Watch
The IWC Portugieser Chronograph IW371617 presents the classic silver-dial configuration that has been the collection's signature since the model's introduction. The silver-plated dial with its finely grained texture creates a timeless, dressy aesthetic that pairs effortlessly with both business and formal attire. The applied blued hands and blued chronograph seconds hand contrast beautifully against the silvery background, ensuring superb legibility. Powered by the in-house caliber 69355, this chronograph benefits from IWC's proprietary Pellaton winding system, which uses a pair of pawls with ceramic tips to wind the mainspring in both directions with exceptional efficiency. The 41mm stainless steel case features a mix of polished and brushed surfaces that catch the light elegantly without appearing ostentatious. The convex sapphire crystal sits flush with the bezel, contributing to the clean, refined profile. Paired with a black alligator leather strap, this configuration represents the most traditional expression of the Portugieser Chronograph — a watch that has remained essentially unchanged in its design philosophy since 1939. For many collectors and enthusiasts, the silver-dial Portugieser Chronograph is the definitive IWC, a perfect balance of horological sophistication and understated elegance.
