Editor's Notes

Made from stainless steel and glossy alligator, this IWC SCHAFFHAUSEN 'Portugieser' watch features the manufacturer's newly developed annual calendar complication. It's meticulously engineered to consider the differing lengths of individual months and thereby only requires manual correction at the end of February, to account for leap years. Powered by an IWC-manufactured 52850 calibre automatic movement behind the eye-catching midnight-blue sunray dial, it's finished with an 18-karat gold 'Probus Scafusia' medallion at the sapphire-glass case back to ensure its luxury can be clearly admired by all.

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
