Experience the craft of IWC in the Portofino (ref. IW5164-06), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 45 mm in diameter, with a thickness of 13.2 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a white tone with gloss finish, framed by stick / dot hour markers, and feuille hands. At its heart beats a proven engine: the 59800 caliber. Produced in limited numbers, appealing to focused collectors. Initial production year: 2018. 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.
