A masterpiece of refined engineering and timeless style, the IWC Portugieser Automatic 7 Days Ref. IW500703 is a standout in the world of classic luxury watches. With its balanced proportions and clean, highly legible layout, this model pays tribute to IWC’s rich maritime heritage while showcasing the brand’s modern technical prowess.

The 42.3mm stainless steel case houses a striking black dial adorned with applied silver-tone Arabic numerals, elegant feuille (leaf-shaped) hands, and a railroad-style chapter ring. The dial features a 7-day power reserve indicator at 3 o’clock and small seconds at 9 o’clock, perfectly balancing form and function.
