The IWC Portofino Chronograph (ref. IW391025) takes its design cues from the 1960s, with sporty push-buttons and chronograph displays. The case is 18-carat 5N gold. The dial is silver-plated with 5N gold numerals and sits under a convex sapphire glass.
The watch is powered by the self-winding 75320 caliber, which has a 44-hour power reserve. The case back is engraved with a view of the harbour at Portofino. It comes on a dark brown alligator leather strap.
