The IWC Portugieser Grande Complication IW377602 is one of the most exclusive limited editions in IWC’s history, with only 250 pieces produced. Encased in 45mm of warm 18K 5N gold, measuring 16.5mm thick, this timepiece embodies the absolute summit of Swiss watchmaking artistry.
The silver-plated dial is protected by an arched-edge sapphire crystal with antireflective coating on both sides. The Calibre 79091 automatic movement provides approximately 44 hours of power reserve and integrates a perpetual calendar with date, day, month, and year indicator, a chronograph, a moonphase display, and the revered minute repeater complication.
Presented on a dark brown alligator leather strap by Santoni, this Grande Complication in 5N gold is a statement of uncompromising luxury and horological mastery. Water resistant to 3 bar.
