Patek Philippe Perpetual Calendar Chronograph

Grand Complications is the top of the mountain, the collection that holds the watches Patek's entire reputation rests on. This is where you find perpetual calendars that track leap years and won't need adjusting until 2100, minute repeaters that chime the hours and minutes on tiny gongs, split-seconds chronographs, and astronomical watches that map the actual night sky across the dial. At the very peak sits the Grandmaster Chime, one of the most complicated wristwatches ever made. These are the pieces that break auction records and take years to build, so prices run from deeply serious into the millions. You're not shopping here so much as admiring, but it's the clearest window into why Patek is Patek.
