The IWC Portugieser Grande Complication is a masterpiece of haute horology and combines breathtaking complications with the timeless elegance of the Portugieser range.
A slide on the left releases the minute repetition and indicates the time (hour, quarter hour and minute) by sound. The perpetual calendar shows day, date, month, year and moon phase. This engineering marvel automatically calculates the different lengths of the months as well as the leap years, which avoids the need for manual adjustment over years. The integrated chronograph gives accurate time reading and has subtle displays for seconds, minutes and hours, with the functionality of adding up stop times.
The IWC Portugieser Grande Complication represents the spirit of the Portuguese seamen, which is also indicated by the engraving on the back of the pink gold case. A sextant, another essential tool of nautical navigation points to this spiritual connection.
