IWC adds a moon phase to its Portofino collection

One of IWC's most elegant watches is getting the moon phase treatment with a new model that adds the watchmaker's 59800 caliber. The movement is a hand-wound caliber that has an 8 day power reserve when fully wound and features a power reserve display on the dial. The 45mm case comes in stainless steel or 18-carat red gold and both watches come on an alligator leather strap from Italian brand, Santoni.
