Provenance: Amateur collection
Note: Introduced in 2003, reference IW5021 is a cult model in the Portugieser collection. Known as "PPC" to insiders, this watch features an entirely new display: a double lunation indicating the moon phases in the northern and southern hemispheres - a world first patented by IWC! Equipped with an impressive 7-day power reserve, this watch was developed by Kurt Klaus, IWC's star watchmaker in charge of innovation and research for almost 50 years. Unlike "traditional" perpetual calendars, i.e. with correctors on the case, this model is revolutionary in that all adjustments are made via the crown. This tour de force makes it particularly easy to use. Like all pieces in this series, our model comes with a second disc for leap years.
