Details & Specifications
Description:
The IWC Portofino Chronograph (IW391036) marries the Portofino collection's 1960s design sensibility — with elegantly sporty push-buttons and chronograph displays — to IWC's vision of impeccable Swiss precision, presented in a stainless steel case with a striking blue dial, slender gold-plated feuille hands, applied gold-plated indices and Roman numerals, and a hand-painted black alligator leather strap. The 42mm case houses IWC Calibre 75320, an automatic movement with a 44-hour power reserve, offering a full chronograph with 60-second, 30-minute, and 12-hour sub-dials, plus a day and date display at 3 o'clock, all behind a scratch-resistant, convex sapphire crystal with anti-reflective coating on both sides and a transparent case back.
This piece presents in mint condition with the original box.
