The IWC Portugieser (ref. IW358401) continues the lineage of understated precision that has defined the collection since its 1930s origins. Presented in a 40mm 18ct rose-gold case with a black dial, this streamlined automatic returns to the clean symmetry and restrained ornamentation that made the original marine chronometer‑inspired design so widely admired.

At its heart is IWC’s in‑house calibre 82200, a self‑winding movement with Pellaton winding system, delivering reliable energy to the small seconds subdial at 6 o’clock. The transparent caseback reveals refined finishing, while the case itself is water‑resistant to 30 m. Though more compact than the legacy 42mm design, the 40mm format preserves balance and wrist presence, making it one of the most daily‑wearable Portugieser variants.

The IW358401 merges early 20th‑century functionalism with modern watchmaking, creating a reference equally suited to collectors seeking heritage purity or simply a refined hand in gold.
