The Portofino Midsize Automatic comes in four red-gold and six stainless-steel versions, each of which is available with a diamond-set bezel or a slightly more understated variation with 12 jewels on the dial. The finished mirror-polished case surfaces lend these timepieces a real air of exclusivity, as does the sun-pattern finish on the dials, which makes the light appear to move around in circles when the watch is tilted from side to side.

Another feature on the new Midsize models is the slightly raised inner circle on the dial which adds structure and depth to the watch face. In addition to the hour, minute and seconds hands, the Portofino Midsize Automatic also features a rapid-advance date display. All of these functions are powered by a mechanical automatic movement. Pulling out the crown stops the central hacking seconds hand, and the sapphire glass has antireflective coating on both sides to guarantee a clear view of the display.  Alligator leather straps complement the dial and case of nine of the models, while reference IW458110 features a Milanaise mesh bracelet. Each timepiece is also available with a 1960s style Milanaise bracelet in high-quality stainless steel or 18-caratred gold.
