IWC Schaffhausen - Portofino

Portofino Automatic 37

Stainless steel case, 37 mm. Model IW458603
Editor's notes

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. This version features a stainless steel case, a slate-coloured 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. 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 taupe 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.
