IWC Portugieser Perpetual Calendar 44.2mm

Kurt Klaus's perpetual calendar is one of the great achievements of modern watchmaking: the entire calendar — date, day, month, four-digit year, and a double moon phase accurate to one day in 577.5 years — is set through the crown alone.

The in-house 52615 calibre with IWC's Pellaton winding system delivers a full seven-day power reserve. On the wrist it is pure Portugieser: thin bezel, expansive silver dial, and railway minute track — grand complication watchmaking in the house style.
