Paying tribute to an iconic Grand Complication, Patek Philippe has created a jewelry version of its chronograph with perpetual calendar Reference 5271, enhanced by 81 baguette-cut diamonds (5.01 cts). The aesthetic harmony is complemented by the lacquered black dial and the shiny black alligator strap.
