With its reduced case diameter of 37 millimeters, the Portofino Automatic 37 has become a staple in IWC’s ladies’ watches portfolio, offering excellent wearing comfort on more slender wrists. This version features a stainless steel case, a slate-colored dial, and rhodium-plated hands and appliques. On the dial, 12 diamonds mark the hours. At work inside is the IWC-manufactured 32111 calibre, which uses a bidirectional pawl winding system to build up a power reserve of 120 hours.
