IWC Portofino Automatic Day & Night 34
IW459805
The IWC Portofino Automatic Day & Night gives the collection’s restrained round silhouette a poetic complication: a rotating disc lets a small sun or moon rise into view as the hours pass. Warm gold frames the silver-plated dial, while the taupe calfskin strap keeps the composition softly understated and can be exchanged through IWC’s quick-change system. The result preserves Portofino’s easy elegance while making the rhythm of day and night its most expressive detail.
