Introducing IWC Portugieser (ref. IW5042-07), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white 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. Introduced in 20062009. 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.
