For almost 2 centuries, the prestige, quality, and elegance of the art of horology have been symbolized through the creations of Patek Philippe. The Calibre 89, a remarkable legacy of genius: 332 screws, 129 rubies, 429 mechanical components, 68 springs, 24 hands, 184 wheels, a perpetual and secular calendar, phases of the moon, and a chronograph. Only 4 of these complicated-maddening works of utter decadence are in existence. Love the art of horology? Add the Patek Philippe Museum in Geneva, Switzerland to your bucket list.
