Why We Love This Watch
This pre-owned IWC Portugieser Grand Complication ref. IW377602 (2021) is a masterful blend of technical sophistication and timeless elegance. Housed in a 45mm 18 ct 5N gold case with a silver-plated dial, it is powered by IWC’s automatic Caliber 79091, offering a 44-hour power reserve and small hacking seconds. The watch features an array of extraordinary complications, including a chronograph (hours, minutes, seconds), a perpetual calendar with date, day, month, year (four digits), moon phase display, and a minute repeater chiming hours, quarters, and minutes. An arched-edge sapphire crystal with antireflective coating ensures optimal legibility, while the 22mm strap and 18mm buckle provide a refined fit. This Portugieser Grand Complication is a striking example of IWC’s horological mastery, combining precision, luxury, and classic design in one exceptional timepiece.

IWC Portugieser Grand Complication IW377602 18k 5N Case

Pre-owned IWC Portugieser Grand Complication ref IW377602 (2021) is the absolute upper end of what the Portugieser line was ever meant to explore. The Grand Complication isn’t just another Portugieser with extra functions. It’s IWC’s way of bringing nearly every traditional high complication into a single wristwatch. Inside are 659 individual components working together to deliver a chronograph, a full perpetual calendar with a four-digit year, a perpetual moon phase, and a minute repeater that chimes the hours, quarters, and minutes on demand. That’s centuries of watchmaking ideas condensed into one case. Here, those complications are housed in a substantial 15ct 5N gold case with a clean, silver-plated dial that is surprisingly legible for how much is going on. The watch wears large at 45mm, but that scale feels appropriate given what it’s carrying. The watch is powered by IWC’s self-winding caliber 79091 with a 44-hour power reserve. It’s paired here with a dark brown Santoni alligator strap. This model is the kind of watch collectors look at less as an everyday watch and more as a statement of what mechanical watchmaking can still achieve.
