IWC Portofino Chronograph Description
The IWC Portofino Chronograph, reference IW391031, combines a classic round case with the practical displays of a chronograph. IWC lists this reference with a 42 mm stainless-steel case and a silver-plated dial.
The photographed watch has a light-colored dial with gold-colored hands and markers. Three subdials give the face its distinctive layout, while the day and date appear together at 3 o’clock. Two pushers flank the crown, and a dark brown strap with an IWC-signed pin buckle completes the look.
IWC specifies a self-winding movement and chronograph function for the reference. The combination of a polished case, restrained dial and useful displays gives the IWC Portofino Chronograph an elegant yet functional character.
