Editor's Notes

IWC SCHAFFHAUSEN's 'Portugeiser' watch is engineered with the ingenious perpetual calendar developed by head watchmaker Mr Kurt Klaus in the early 1980s - it displays the date, day, month and moon phase, and even indicates when it's a leap year. Manufactured in Switzerland with an 18-karat gold case, it's powered by an in-house calibre 82650 automatic movement and set on a classic dark-brown alligator strap.

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