Portuguese Perpetual Calendar

The moon phase display of the Portugieser Perpetual Calendar deviates from the actual course of the moon by only one day in 577.5 years. The elegant timepiece leaves virtually nothing to be desired. It features a perpetual calendar with a four-digit year display and a seven-day automatic movement with Pellaton winding. The silver dial displays the moon phase, date and power reserve, the month, day of the week and small seconds in four apertures. The watch is powered by the IWC-manufactured movement from the 52000 calibre family with solid red gold oscillating weights and blued screws. The 18-carat red gold watch with a glass dial with an arched edge is worn with a dark brown alligator strap.
