The IWC Portugieser (ref. IW358404) refines one of the brand’s most enduring designs into a modern, compact format, pairing rich materials with precision engineering. Its 40mm rose-gold case balances warmth and sophistication, framing a clean silver dial punctuated by a small seconds display at 6 o’clock – a nod to the collection’s marine chronometer roots.

Driving the watch is IWC’s in-house calibre 82200, an automatic movement equipped with a Pellaton winding system and designed for robust daily use. Its architecture includes ceramic components for enhanced longevity, while precision remains central, with a practical small-seconds display and bidirectional winding. The 40mm case brings IWC’s traditionally large Portugieser silhouette to a more versatile wrist presence, with the rose-gold construction accentuating the pared-back elegance of the silvered dial layout.

Introduced in 2025, this reference distills the aesthetic legacy of the Portugieser into a more wearable profile without compromising the model’s historic appeal. With its refined proportions, mechanical integrity, and precious-metal case, the IW358404 offers entry into IWC’s most iconic line in a format suited to contemporary collectors.
