Inspired by the relaxed elegance of the Italian Riviera, the Portofino collection reflects IWC’s signature approach to refined simplicity. The Portofino Automatic Day and Night 34, Reference IW459805, brings that philosophy to a smaller and more poetic format with a polished 34 mm case and a graceful, balanced dial layout. At 6 o’clock, a rotating 24 hour disc transitions between sun and moon motifs, offering a charming visual representation of the time of day. The silver plated dial, set with classic applied markers, enhances the watch’s understated character.

Powered by the automatic calibre 35180, the watch delivers a dependable 50 hour power reserve, while the convex sapphire crystal ensures clarity from every angle. Water resistance to 5 bar and a refined leather strap complete a design that blends everyday wearability with quiet sophistication.
