A one-of-a-kind masterpiece, this Planetaria watch is part of Vacheron Constantin's Les Cabinotiers collections - the series reserved for the most complicated one-off watches. The new piece is powered by a new Grand Complication movement, caliber 1991, which was four years in the research and development stages. The watch boasts a retrograde jumping perpetual calendar that is regulated by a double-axis tourbillon and precise moonphases for both the northern and southern hemispheres, which are depicted by three-dimensional globes on the dial. It also is equipped with a retrograde date, a circular retrograde month and day indicator, and day/night indications for the two hemispheres. It is regulated by a double-axis tourbillon that is three-dimensional, and housed in an armillary sphere, which is also visible via a sapphire window in the watch case side. The incredible new manual-wind caliber consists of 745 components and carries the Hallmark of Geneva certification attesting to the incredible craftsmanship and finishing that goes into each and every part. This one-of-a-kind timepiece is crafted in 18-karat 5N pink gold with an opaline silvered dial.
