Introducing IWC Portugieser (ref. IW5022-13), a contemporary classic shaped by careful watchmaking know-how.

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, framed by arabic numerals hour markers, and feuille hands. Among collectors, it is nicknamed "Single Moon". At its heart beats a proven engine: the 51613 caliber. Introduced in 20062012. 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.
