Notes

IWC, “Portugieser Perpetual Calendar”

The moon phase display on the “Portugieser Perpetual Calendar” diverges by just 1 day in 577.5 years from the actual phase of the moon. In the model with the double moon display, the moon phase and its mirror image show the state of the moon in both the northern and southern hemispheres.
