Learn More

The IWC Portofino collection has long been regarded as one of the Swiss industry's most elegant expressions of dress-watch philosophy. Born from the spirit of the Italian Riviera town that inspired its name, the Portofino line has since its introduction embodied a commitment to clean lines, precious materials, and movements of genuine quality — a formula that has earned it devoted collectors on both sides of the Atlantic.

Reference IW357415 brings that heritage into sharp contemporary focus with an 18-carat 5N gold case measuring a refined 34mm in diameter. The designation 5N refers to IWC's proprietary rose-gold alloy formulated for a distinctly warm, deep pinkish-gold hue that reads richer and more saturated on the wrist than standard 18k rose gold. The case proportions are deliberately feminine without being fragile, offering a presence that reads elegantly on a range of wrist sizes.

The dial is the defining statement of this reference. A deep green ground — a shade that has become one of the most sought-after dial colors in contemporary luxury watchmaking — is appointed with diamond-set indices and applied Roman numerals, adding texture and light play that shifts beautifully under different lighting conditions. The gold bezel frames the dial with quiet authority, maintaining the cohesive all-gold aesthetic that collectors prize in precious-metal dress watches.

Powering the IW357415 is an automatic movement, reflecting IWC's commitment to mechanical excellence even in its most aesthetically driven references. The watch is presented on a leather strap that complements the warmth of the 5N gold case and the richness of the green dial — a combination that works equally well with formal attire and elevated casual wear. Every element of this watch has been conceived to work in harmony.

Bizak & Co. offers this brand-new IWC Portofino IW357415 for sale with the full confidence of an authorized and reputable luxury watch dealer. Whether you are adding a milestone piece to your collection, searching for an extraordinary gift, or exploring the IWC Portofino line for the first time, our team is ready to assist you.
