IWC Portugieser Chronograph Blue Dial

About This Watch

The IWC Portugieser Chronograph IW371609 showcases a stunning sunburst blue dial that has become one of the most sought-after colorways in the collection. Powered by the in-house caliber 69355, this chronograph features the iconic Portugieser design language with its railroad chapter ring, leaf-shaped hands, and applied Arabic numerals. The 69355 movement, part of IWC's 69000 family, incorporates the Pellaton automatic winding system with ceramic components for exceptional durability and reliability. At 41mm, this reference represents the modern sizing of the Portugieser Chronograph, slightly reduced from the previous 42mm generation. The vertical bi-compax layout with small seconds at 9 o'clock and 30-minute counter at 12 o'clock maintains the clean, balanced aesthetic that has defined the Portugieser since its origins in 1939. The blue dial catches light beautifully, shifting from deep navy to vibrant azure depending on the angle. Despite its dress-watch elegance, the sapphire crystal and 30-meter water resistance provide adequate everyday protection. The Portugieser Chronograph remains IWC's best-selling model and a cornerstone of modern luxury watchmaking.
