IWC Portugieser Grande Complication - A masterpiece of the watchmaker's art. A watch for true collectors. The minute repeater also makes it an acoustic masterpiece of fine watchmaking.

The IWC Portugieser Grande Complication (Ref. IW377402) is a highly complex timepiece that combines technical precision with classic elegance. Crafted from 18-carat red gold, it has an impressive 45 mm case with a harmoniously integrated push-button system for controlling the functions. At its heart is the IWC-manufactured 79091 caliber, a mechanical chronograph movement with automatic winding and a power reserve of 44 hours. The chronograph has a stop function for hours, minutes and seconds. The watch is equipped with a perpetual calendar that displays the date, day of the week, month, year in four digits and moon phases precisely up to the year 2100. Another technical refinement is the minute repeater, which audibly indicates the current time at the touch of a button. The sapphire crystal with anti-reflective coating on both sides protects the dial, while the finely crafted alligator leather strap with a red gold folding clasp offers maximum wearing comfort. The water resistance is 3 bar (30 meters).
