Vacheron Constantin combined 11 complications at once in Les Cabinotiers Dual Moon Grand Complication watch. This one-of-a-kind watch is powered by the hand-wound caliber 755 TMRCCQP. On the dial are hours and minutes, below them are the perpetual calendar indicators (day of the week and month), above is a retrograde date scale, in the center are the phases of the moon and its age for both hemispheres, at 3 o'clock is a leap cycle window.
On the reverse side there is a tourbillon, a star map and sidereal time (or the real time of the Earth's rotation - for 23 hours 56 minutes and 4 seconds). The sapphire glass with the constellations applied to it rotates, indicating the position of the constellations, limited by the celestial sphere. Also included in the "set" is a minute repeater (chimes hours, quarter hours and minutes).
