Decades of expertise, pioneering design and meticulous engineering culminates in the creation of IWC Portugieser watches. Invented by the legendary IWC watchmaker Kurt Klaus, IWC Portugieser watches are so smart that they give you the precise day, date, moonphase and time for the next 480 years – and beyond. The perpetual calendar watches of the IWC Portugieser collection feature striking dials in black, white and blue. Bold hour markers combined with an elegant alligator strap create a commanding statement timepiece. The automatic, self-winding movement provides unparalleled timekeeping capabilities.
