With its reduced case diameter of 37 millimetres, the Portofino Automatic 37 has become a staple in IWC’s ladies’ watches portfolio, offering excellent wearing comfort on more slender wrists. The version features a stainless steel case, a silver-plated dial, and rhodium-plated hands and appliques. The case and the dial are decorated with 72 diamonds weighing 1.12 carats. Because of an improved setting, the diamonds reflect the light better and have a more visible presence and added brilliance. 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. A see-through sapphire glass back displays the movement, which has been finished with a gold-plated rotor and blued screws. This ladies’ watch is fitted with a blue strap made of fully traceable Swiss calf leather. The strap has a natural and soft finish and boasts a contemporary, luxurious feel. Thanks to the integrated quick-change system, the strap can be exchanged easily.
