Patek Philippe launches a new Quadruple Complication for connoisseurs with minute-repeater, split-seconds chronograph and instantaneous perpetual calendar. The new self-winding R CHR 27 PS QI caliber (799 components) features several innovations, including two new patents optimizing energy management. The instantaneous perpetual calendar ensures that the disks pass in 30 milliseconds over the three day-date-month apertures arranged along an arc. The entirely polished white gold case is complemented by a sunburst ice blue dial and a shiny navy-blue alligator strap with a new patented triple-blade fold-over clasp.
