The family is now complete. All that was missing was the new Ref. 5204 Split-Seconds Chronograph with Perpetual Calendar to round out the range of classic Patek Philippe chronographs. At the turn of the millennium, the Manufacture launched a vast offensive in the field of the chronograph, introducing a number of “in-house” calibres displaying peerless technical mastery. It is now once again asserting itself in the field of Grande Complication models by introducing the most modern representative of this type of movement. A technical breakthrough housed inside a platinum case and based, in addition to the construction of the perpetual calendar, on a calibre boasting six patented innovations, including an isolator system for the split-seconds lever and a mechanism guaranteeing reduced offset between the split-second and chronograph hands.
