The Patek Philippe Grandmaster Chime 6300/400G-001 is crafted in a 49.4mm white gold case and styled on a leather strap. The black opaline dial is highlighted by glamorous set with 409 baguette-cut diamonds on the case and bezel. The watch features over 20 complications shared between the dual-faced dials. From Grande and petite sonnerie to perpetual calendar timekeeping, this Haute Joaillerie version has elevated one of the most complicated timepieces to date.
