About the Grand Complications family
Grand Complications is Patek Philippe's heading for its most complex watches: perpetual calendars, split-seconds chronographs, minute repeaters, tourbillons and astronomical displays such as the sidereal time and sky charts of the Celestial models. It continues a tradition that goes back to the brand's complicated pocket watches.
References in the catalog include perpetual calendars such as the 5160/500R with an engraved case, the minute repeater perpetual calendar 5374, the Celestial 6104 and the Grandmaster Chime 6300, a reversible watch with grande and petite sonnerie. Production of many of these is very small. For dealers, provenance, the Certificate of Origin, an Extract from the Archives and service by the brand matter more here than anywhere else in the range.
