IWC Portugieser Automatic 40mm Stainless Steel Black Dial IW358313

The IWC Portugieser collection traces its origins to the 1930s when Portuguese merchants requested exceptionally accurate marine chronometers. This IW358313 model continues that legacy of precision with its sophisticated 40mm stainless steel case housing the advanced Calibre 82200 movement. The design exemplifies IWC’s aviation heritage through its clean, legible dial featuring silver-tone hands and Arabic numerals against a silver-tone background. The small seconds complication at 6 o’clock adds classical elegance while maintaining perfect timekeeping. Crafted with Swiss precision, the movement operates at 28,800 vibrations per hour and features 33 jewels for optimal performance. The transparent case back allows appreciation of the finely finished movement, while the black alligator leather strap provides both comfort and sophistication. Ideal for business professionals and watch enthusiasts, this timepiece transitions seamlessly from boardroom to evening events, embodying IWC’s philosophy of functional luxury and engineering excellence that has defined the brand since 1868.
