About the Model

The IWC Portofino (ref. IW458603) refines the minimalist charm of its namesake collection with a more compact presentation and a cooler modern hue. Released in 2022, this 37mm configuration in stainless steel introduces a grey sunburst dial that plays subtly with ambient light – understated but unmistakably elegant.

Powering the watch is the IWC-manufactured calibre 32111, a self-winding movement visible through a sapphire caseback. Designed for robustness and efficiency, the automatic calibre delivers an ample 120-hour power reserve while maintaining a slim profile suitable for daily wear. The polished steel case is water-resistant to 50 m, ensuring usability beyond the dinner table.

Sized for versatility, the IW458603 reprises the Portofino’s classic proportions in a contemporary colourway, making it a compelling entry point into IWC’s design philosophy. It balances heritage cues with modern refinements, offering arresting simplicity backed by mechanical substance.
