IWC Portugieser - Grande Complication - Chronograph - Perpetual Calendar - Minute Repeater - Rose Gold - 45 MM - Silver Dial - IW377602

The Portugieser Grande Complication stands as a testament to the pinnacle of horological mastery, integrating an array of remarkable complications. At its core lies the perpetual calendar, meticulously programmed until the year 2499, requiring only three adjustments in non-leap years of the 22nd and 23rd centuries. Further enhancing its complexity are the perpetual moon phase display, chronograph, and minute repeater, which chimes the time with harmonious tones when activated by the repeating slide. A symphony of 659 individual mechanical parts orchestrates a total of 20 functions, showcasing the ingenuity of watchmaking craftsmanship. Despite its intricacies, the case maintains a water resistance of 3 bar, ensuring durability and versatility. The exclusive 18-carat 5N gold model, limited to 250 watches, is adorned with a dark brown alligator leather strap from Santoni, meticulously stitched with a 5N gold thread. The engraving on the case back, resembling a compass rose, adds a touch of sophistication and elegance to this extraordinary timepiece.
