Introducing IWC Portofino (ref. IW4590-06), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 37 mm in diameter, with a thickness of 11 mm, defined by a round silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a blue tone, framed by gem-set indexes hour markers, and feuille hands. At its heart beats a proven engine: the 35800 caliber. Issued as a limited edition, appealing to focused collectors. Initial production year: 2016. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
