Editor's Notes

IWC SCHAFFHAUSEN has preserved a reputation for building some of the most sophisticated watches in the industry for 150 years. The 'Portofino' line is among its most stylish, inspired by yachting to the famed Italian harbour in the summers of the '60s. This chronograph features a deep blue dial, framed with an 18-karat red gold case and sporty push buttons of the era. Flip it over to see a vista of the port that has been hand-engraved at the house's Swiss workshop.

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
