IWC Portofino Chronograph Watch, 42mm White Dial, IW391031

With its striking push-buttons and functional, technology-inspired dial, this chronograph brings a refreshingly sporty note to the Portofino family. The Portofino Chronograph takes its design cues from the 1960s, with elegantly sporty push-buttons and chronograph displays. The stainless-steel chronograph watch has a convex sapphire glass and appliqué Roman numerals on its silver-plated dial. It is powered by the tried and tested self-winding 75320 calibre with its 44-hour power reserve and comes with a black alligator leather strap.
