A modern icon rooted in maritime legacy, the Portugieser Chronograph IW371605 features a 41 mm stainless-steel case and a slim profile that emphasizes its open, elegant dial. The silver-plated face is detailed with blued feuille hands, applied Arabic numerals, and a quarter-second rail track — recalling IWC’s nautical-precision heritage.

Under the sapphire case back pulses IWC’s in‑house Calibre 69355, a column-wheel chronograph movement that delivers a 46-hour power reserve and reliable performance. The watch is paired with a deep blue alligator leather strap, combining sophisticated aesthetics with refined comfort. Water-resistant to 30 m, it’s designed for both dress occasions and daytime wear, offering classic style with mechanical excellence.
