Introducing IWC Portugieser (ref. IW5901-08), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in red gold and measuring 46 mm in diameter, with a thickness of 13.4 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 silver tone with sunburst finish, framed by arabic numerals hour markers, and feuille hands. At its heart beats a proven engine: the 94800 caliber. Released in a constrained run, appealing to focused collectors. Introduced in 2017. 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.
