IWC Portugieser Perpetual Calendar Watch

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