IWC's Portofino collection has been around since the late 1970s but the luxury watch brand have only recently added a new line of watches to it. Welcome the Mid-Size Automatic Portofino watches. As you may have guessed by the name, these are a smaller size to the original 40mm Portofino. With a 37mm diameter case, each pieces features diamonds either as the indexes or on the bezel and comes with an 18-carat rose gold or stainless steel case with an alligator leather strap or a stainless steel bracelet.
