The unworn IWC Portofino Chronograph, Ref# IW391031, blends timeless elegance with refined functionality, capturing the spirit of 1960s sophistication. Housed in a polished 42mm stainless steel round case, 13.5mm thick, and the watch exudes balanced proportions and understated luxury. Its silver-plated dial features applied polished gold tone applied index and Roman numeral in position 6 and 12 o’clock hour markers, paired with slender gold tone hands, all set against a finely printed minutes, seconds, and fractions-of-a-second track where every 5 minutes are marked with Arabic numerals for precise time reading. At 3 o’clock, a neatly framed day and date display adds everyday practicality. The chronograph layout is impeccably balanced, with a 30-minute counter at 12 o’clock, a 12-hour counter at 6 o’clock, and a small seconds sub-dial at 9 o’clock. The large central chronograph seconds hand ensures clear timing at a glance. Inside, the IWC caliber 75320 — a robust automatic movement beating at 28,800 vph with 25 jewels — offers a 44-hour power reserve, safeguarded by a scratch-resistant sapphire crystal and a solid case back. Elegant, elongated push-buttons and chronograph displays nod to vintage chronographs, while the black alligator leather strap completes the look with a touch of classic Italian flair. Water-resistant to 30 meters, the Portofino Chronograph is as versatile as it is stylish — equally at home in formal settings or casual weekends.
