Haute Complication: IWC Portugieser Perpetual Calendar Edition “150 Years”

IWC celebrated their 150th anniversary in style, with a special 'Jubilee Collection' of which this Portugieser Perpetual Calendar is also a member. In the history of IWC, this is an important complication, revolutionized by their very own Kurt Klaus, who was the brand's Head of Development and Research when the legendary Da Vinci Perpetual Calendar took the watch world by force.
