Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication Watch
With 23 different complications primarily devoted to the study of the night sky, the Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication Watch is one of the world's most complex timepieces. On the front, it offers traditional time indications, a perpetual calenday, a precise moon phase, solar time indications, and a tide-level indicator with a 3D depiction of the alignment of the Earth, Moon, and the Sun. The back dial is dedicated to a transparent celestial chart, which lets you admire the inner workings of the watch while observing celestial time in both hours and minutes. It's housed in a 45mm 18K white gold case, finished with a black alligator leather strap, and is one-of-a-kind.
