Paying tribute to an iconic Grande Complications, Patek Philippe has created a jewelry version of its chronograph with perpetual calendar Reference 5271, enhanced by 80 baguette-cut rubies (5.25 cts) set on the bezel, the lugs and the fold-over clasp. The intense color of the gems is echoed by the lacquered red dial with black-gradient rim and the shiny black alligator strap with contrasting stitching. Manually wound mechanical movement, platinum case.
