As part of the new “150 Years” collection, which includes already two superb watches, the re-edition of the Pallweber and the Portugieser Tourbillon Constant Force, IWC treats us with an unprecedented combination of complications, integrated inside the iconic Portugieser case. Using the classical nautical look of this model with the addition of the new lacquered dials, here is the IWC Portugieser Perpetual Calendar Tourbillon Edition 150 Years, introduced as a Pre-SIHH 2018 novelty, and part of the 27 special watches that the brand will unveil at the 2018 Geneva watch fair.
