The IWC Portofino collection has long been regarded as one of Swiss watchmaking's most eloquent tributes to Italian dolce vita — clean, confident, and unashamedly elegant. Introduced as a line that celebrated the leisurely pace of the Ligurian coast, the Portofino family distills centuries of horological tradition into slim, legible cases that suit everything from a weekend lunch to a formal dinner. Reference IW357413 represents the 34mm chapter of that story, sized with intention for a wrist presence that is refined rather than commanding, and dressed with details that reward close attention.

The 34mm stainless steel case of the IW357413 occupies the sweet spot between bracelet-scale subtlety and a watch that reads with genuine authority on the wrist. Stainless steel was chosen for its durability, its neutral luster, and its ability to complement the deep blue dial without competing with it. The case profile is characteristically Portofino: smooth, polished surfaces that catch and scatter ambient light, clean lugs, and a crown designed to be operated with effortless ease.

The blue dial is the unambiguous focal point of this reference. IWC has finished it in a tone that shifts in character as the light changes — appearing oceanic under bright illumination and approaching midnight in shadow. Diamond indexes replace the standard hour markers, introducing a constellation of brilliance that elevates the watch from an instrument of timekeeping to a piece of jewelry calibrated to horological precision. Roman numerals complete the chapter ring, reinforcing the classical disposition that the Portofino line has always championed.

Powering the IW357413 is an automatic movement, a hallmark of the Portofino Automatic family. IWC's automatic calibers in this line are known for their reliability, smooth sweep of the seconds hand, and the satisfying feel that only self-winding mechanical watchmaking can offer. Because the watch winds itself through the motion of the wearer's wrist, it is perfectly suited to daily wear without requiring the manual attention of a hand-wound timepiece.

On the wrist, the stainless steel bracelet integrates seamlessly with the case, providing both comfort for extended wear and a cohesive, polished aesthetic. The combination of a cool steel bracelet, a glowing blue dial, and the sparkle of diamond indexes creates a watch that transitions effortlessly from a professional context to an evening occasion. Whether worn as an everyday companion or reserved for special moments, this reference delivers consistent visual satisfaction.

Bizak & Co. is pleased to offer this IWC Portofino IW357413 in brand-new condition, complete with box and papers, at the best available price. Purchasing from Bizak & Co. means working with an experienced luxury watch dealer committed to authenticity, transparency, and a seamless buying experience.

The IW357413 stands out for its striking combination of a deep blue dial set with diamond hour indexes and Roman numerals housed in a 34mm stainless steel case. This blend of classical Portofino design language and jewelry-grade details makes it one of the most elegant references in the current Portofino lineup. It appeals equally to collectors who appreciate understated luxury and to buyers seeking a diamond-set watch with genuine Swiss mechanical credibility.

2. What movement powers the IWC Portofino IW357413?
The IW357413 is powered by an automatic (self-winding) mechanical movement, consistent with the Portofino Automatic family.

IWC automatic calibers in the Portofino line are well-regarded for their reliability and smooth timekeeping.

3. What is the case size of the IWC Portofino IW357413?
The IWC Portofino IW357413 features a 34mm stainless steel case, making it a refined, elegantly proportioned choice. This size is versatile and particularly well-suited to those who prefer a classic, understated wrist presence rather than an oversized statement piece. The 34mm diameter sits comfortably within the tradition of dress watches.

4. Is the IWC Portofino IW357413 suitable for everyday wear?
Yes, the Portofino IW357413 is well-suited to everyday wear thanks to its durable stainless steel case and bracelet and its self-winding automatic movement that requires no daily winding. Its slim, clean profile means it slides easily under a shirt cuff, making it a natural companion for professional and social settings alike. The diamond indexes add a touch of brilliance without making the watch feel too precious or fragile for regular use.

5. What color and finish is the dial on the IW357413?
The dial on reference IW357413 is blue, finished to shift in character depending on the light — vivid and oceanic in bright conditions, deeper and more atmospheric in lower light. Diamond indexes mark the hours, catching the light with each movement of the wrist, while Roman numerals on the chapter ring reinforce the watch's classical, dress-oriented personality. Together, these elements make the dial the defining visual statement of this reference.
