Portugieser Perpetual Calendar 44, Ref. IW503703
Since its appearance almost 40 years ago, IWC’s perpetual calendar has set the bar for effi ciency
and user-friendliness. All its displays are perfectly synchronized and can be conveniently
advanced via the crown. What’s more, we’ve calculated the moon phase so precisely that it will
only deviate by one day in 577.5 years. In the new Portugieser Perpetual Calendar 44, we’ve
packaged the ingenious complication in a case with a slimmer ring and box-shaped sapphire
lenses that make it even lighter and more elegant. That being said, now it’s your turn to keep
looking good for the next centuries.
