Meet IWC Portugieser (ref. IW5042-10), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in red gold and measuring 44.2 mm in diameter, with a thickness of 14.2 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 grey tone, framed by mixed hour markers, and feuille hands. Among collectors, it is nicknamed "Ardiose". At its heart beats a proven engine: the 50900 caliber. Released in a constrained run, appealing to focused collectors. Initial production year: 20082009. 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.
