The striking moon phase display on the Portuguese Perpetual Calendar is a grand-scale theater on a tiny stage. Attended by a cluster of embossed stars, the moon rises behind the hemispherical cut-out on the left and waxes to full moon in the center, before disappearing on the right-hand side. This elegant and modern timepiece features a perpetual calendar, four-digit year display and a seven-day automatic movement with the Pellaton winding system and a power reserve display. This classic watch features an 18-carat white gold case with a handsome ardoise dial and sumptuous dark brown alligator leather strap.
