IWC Jubilee

Jubilee isn't a model line, it's IWC's 150th-anniversary collection from 2018, a run of special editions rather than a design family. For the milestone, IWC took its core watches, Portugieser, Portofino, Da Vinci, and Pilot, and gave them a unified anniversary treatment: lacquered white or blue dials, a commemorative caseback, and in-house movements, in numbered limited runs. Because it spans several collections, there's no single look. Shop it by the underlying model and the specific edition, and treat condition and completeness (box, papers, numbering) as part of the value, the way you would any limited series.
