IWC Portugieser Automatic Steel — Silver-Plated 40 mm Dial | Ref. IW358304

The Portugieser Automatic 40 in reference IW358304 represents the collection's most accessible entry point in terms of wrist presence, reducing the traditional Portugieser diameter to 40.4 mm without compromising the architectural hallmarks that have made this line one of IWC's most enduring. The silver-plated dial carries the characteristic Portugieser grammar — the Arabic numerals and railroad-track minute ring — scaled for a case that will appeal to those who prefer their dress watches at a classically proportioned 40 mm. At 12.3 mm in height, the case maintains a credible profile for formal wear without sacrificing the structural integrity that protects Calibre 82200 within.

Calibre 82200 is a thoroughly accomplished automatic movement, offering approximately 60 hours of power reserve alongside a small seconds subdial at nine o'clock. The absence of a date display — a deliberate choice that preserves the dial's compositional purity — is a knowing acknowledgement that the Portugieser's power resides in restraint. The see-through sapphire caseback provides an unimpeded view of the rotor and bridges, while the bilateral anti-reflective treatment on the convex sapphire crystal ensures the dial's silvered surface is never obscured by unwanted reflections.

The blue alligator leather strap introduces a subtle chromatic dialogue against the silver-plated dial, a pairing that is both confident and considered. At $6,165, IW358304 is positioned as a compelling introduction to the Portugieser's horological values — a watch that delivers the collection's defining aesthetic in a format that is, arguably, the most versatile. Water resistance to 3 bar confirms its identity as a watch for the wrist, not the wrist guard.
