The IWC Portugieser is one of watchmaking's most enduring dress-watch archetypes, born from IWC's early twentieth-century commission to build large, legible timepieces for Portuguese navigators. Decades on, the Portugieser line retains the proportions and philosophy that made it iconic — sweeping thin cases, uncluttered dials, and dauphine hands — while evolving to meet contemporary tastes in both size and color.

The IW358310 brings the Portugieser into the modern era with a 40mm stainless steel case, a diameter that sits comfortably on a broad range of wrist sizes without sacrificing the model's trademark elegance. The case architecture stays true to Portugieser tradition: a slim profile, polished lugs, and a crown that invites daily winding ritual even on an automatic caliber.

The defining feature of this reference is its green Arabic dial. Rich, saturated green has become one of the most coveted dial colors in contemporary horology, and IWC's execution here pairs that fashionable hue with large, boldly printed Arabic numerals — a hallmark of the Portugieser family that prioritizes legibility and a sense of classical proportion over decorative excess. The result is a dial that feels both of-the-moment and timelessly grounded.

Powered by an automatic movement, the IW358310 offers the convenience of self-winding wear with the finishing and reliability IWC is celebrated for. The watch is delivered on an alligator leather strap, a material whose fine texture and slight sheen complement the stainless steel case and elevate the overall wearing experience to genuinely luxury territory.

At Bizak & Co., we source brand-new IWC references with full manufacturer integrity, meaning you receive the watch in pristine, unworn condition exactly as it left the Schaffhausen manufacture. Buying the IWC Portugieser Automatic 40 IW358310 from Bizak & Co. means access to expert guidance, transparent pricing, and the confidence of purchasing from a trusted luxury watch dealer.
