Editor's Notes

The 'Portugieser' watch is an IWC SCHAFFHAUSEN icon, and this 'Boutique Edition' combines classic design features from the original with some of the Swiss label's most impressive technical innovations. Housed in a durable, wear-resistant 18-karat Armor Gold® case, it's engineered with a perpetual calendar complication that displays the date, day, month and year, along with moon phase and power reserve indicators. It's powered by a calibre 52610 automatic movement and set on a midnight-blue alligator strap.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches.
