About this watch

The IWC Portofino IW4581-02 is a masterpiece of luxury watchmaking, blending elegance with functionality. This sophisticated timepiece features a sleek stainless steel case and charming grey dial, perfectly embodying timeless elegance. The round case shines brightly, while the ardoise (grey) dial adds a touch of sophistication. Feuille hands elegantly glide across the grey backdrop, accompanied by gem-set indexes that twinkle subtly, elevating the visual appeal without being ostentatious. At the heart of this watch is the IWC caliber 35111, an automatic movement developed by Sellita according to IWC specifications. This marvel of precision and reliability ensures smooth operation and accurate timekeeping, with a 42-hour power reserve that makes daily winding unnecessary. The Portofino Automatic 37's perfect size (37 mm diameter, 9 mm height) and comfortable wear make it an ideal choice for everyday wear. Paired with a high-quality leather strap, this watch exudes sophistication and is suitable for light splashes and rain. Although not designed for diving adventures, its elegant design, reliable movement, and comfortable fit make it a standout piece in any collection.
