Learn More

The IWC Portugieser is one of watchmaking's most storied dress-watch families, tracing its origins to 1939 when two Portuguese merchants commissioned IWC to produce wristwatches with the accuracy of marine chronometers. That founding ambition—precision in an elegant, uncluttered package—remains the soul of every Portugieser made today, and the IW358404 upholds that tradition with exceptional fidelity.

At 40.4mm, the IW358404 occupies the sweet spot between vintage-inspired proportion and modern wrist presence. The case is crafted entirely in 18-carat 5N gold, a warm rose-toned alloy that IWC selects for its rich depth of color and long-term resistance to surface wear. The result is a watch that catches light with a quiet, aristocratic warmth rather than the brash flash of lesser materials.

The silver-plated dial is a masterclass in restraint. Bold Arabic numerals rendered in a typeface faithful to the original Portugieser maintain instant legibility at a glance, while the uncluttered layout allows the fine silver surface to breathe. The matching gold bezel frames the dial without interrupting it, creating a sense of unified, coherent design that photographs beautifully and wears even better.

Power comes from IWC's in-house automatic movement, a self-winding caliber that reflects decades of Swiss manufacture expertise. A supple leather strap—the traditional and most historically correct choice for any Portugieser—ties the whole package together, sitting elegantly on the wrist whether the watch is worn with a business suit or a formal evening ensemble.

Buying the IWC Portugieser IW358404 brand new from Bizak & Co. means receiving the watch in factory-fresh condition, directly as it left IWC Schaffhausen. As a specialist luxury watch dealer, Bizak & Co. offers competitive pricing, expert authentication, and personalized service. Reach out through bizakandco.com to secure this exceptional gold Portugieser for sale today—an heirloom-quality timepiece that is equally at home in a serious collection or on the wrist of a first-time luxury buyer.
