Editor's Notes

A rare pleasure for watch aficionados in the digital era, this IWC SCHAFFHAUSEN 'Portofino' timepiece is powered by a hand-wound 59800 calibre movement. Designed to run for an impressive 192 hours between each winding, it's an elegant design comprised of a sizable 45mm stainless steel watch case with see-through sapphire glass back, Santoni dark-brown alligator strap, and the central feature - a golden moon phase display that recalls the debut 'Portofino' model from 1984. Set yours with the crown and you'll be able to rely on it endlessly, it will require only a one-day adjustment in 133 years.

We offer an eight-year warranty for all working parts and manufacturing faults for IWC SCHAFFHAUSEN watches. For more information, contact one of our experts by emailing
