The Portofino Automatic Day & Night 34 captures elegance in a refined and feminine form. Crafted in 18 ct 5N gold with a diamond-set bezel, the 34 mm case frames a silver-plated dial with gold-plated hands and appliqués. At 6 o’clock, a day & night display adds a poetic complication, indicating the passing of the sun and moon in graceful detail.

Inside, the IWC-manufactured 35180 calibre powers the timepiece with precision and reliability. This self-winding movement offers a 50-hour power reserve and can be admired through the sapphire glass case back, which reveals fine finishing details. Completing the design, a taupe calfskin strap with quick-change system and butterfly folding clasp ensures comfort and versatility.
