ONE AND ONLY

 

The Dual Moon Grand Complication is a highly complex model distinguished by the legibility of its hourly and astronomical functions, stemming from Vacheron Constantin’s characteristic design quest focused on the essentials. A single-piece edition created by Vacheron Constantin’s Les Cabinotiers department, this double-sided Dual Moon Grand Complication watch has 11 time-related and astronomical complications regulated by a tourbillon and enhanced by a minute repeater emits a rare degree of elegance.

​

There is perfect legibility of the functions and meticulous care devoted to the details of the decoration and finishing. The front features the precision dual moon-phase display, with its age, an impressive show staged in the dial center and complemented by the hours, minutes, and perpetual calendar indicators.

​

Astronomical indications appear on the reverse side of the watch with the time of the sidereal day – which is four minutes shorter than the civil day – and with a sky chart showing the position of the constellations in real-time. The back of the watch also features an opening revealing the tourbillon and its Maltese cross-shaped carriage.
