Editors’ Notes

IWC SCHAFFHAUSEN's 'Portofino' watch is one of the house's most loved styles and this version is scaled down to a 34mm diameter to comfortably fit slender wrists. It's been flawlessly manufactured in Switzerland from 18-karat red gold and is powered by 35100 calibre automatic movement. The simple yet elegant silver-plated dial has gold-plated hands and each hour is marked by a sparkling diamond. The alligator strap is handmade by Italian leather specialists, Santoni, and nods to the expert craftsmanship and fine attention to detail that goes into every timepiece.

All IWC SCHAFFHAUSEN watches still within the initial 2-year warranty period under the original International Limited Warranty will be eligible to benefit from a 6-year extension, for a total of 8 years warranty.
