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 blue baguette-cut sapphires (5.16 cts). The aesthetic harmony is complemented by the lacquered blue dial with black-gradient rim and the shiny black alligator strap with contrasting blue stitching. Manually wound mechanical movement, platinum case.
