The IWC Portofino Chronograph Ref. IW391025 brings a distinctly sporty character to the elegant Portofino collection, combining striking push-buttons with a functional, technology-inspired dial. Its 42 mm case is crafted from 18-carat 5N gold and houses a refined silver-plated dial, complemented by a dark brown alligator leather strap. Measuring 13.6 mm in height, the watch offers 3 Bar water resistance and features a convex sapphire crystal with antireflective coating on both sides. The dial provides a day and date display alongside a chronograph function with hours, minutes, and seconds, while the 20 mm strap and 18 mm buckle complete its sophisticated proportions.

Powering the watch is the Calibre 79320, an automatic self-winding movement operating at 28,800 Vph (4 Hz) with a 44-hour power reserve. The movement comprises 240 components and 25 jewels and features refined Côtes de Genève and Perlage decoration. Small hacking seconds allow precise time setting, while the combination of the 18-carat 5N gold case, functional chronograph, and classic Portofino design creates a refined balance of luxury and sporty performance. The watch is eligible for up to 8 years of warranty through My IWC Care.
