Highlighting Patek Philippe’s great tradition of astronomical watches, the Celestial devotes its dial to a rotating chart of the heavenly bodies. It tells the exact configuration of the nocturnal sky in the northern hemisphere at any time, with the apparent movement of the stars and the phases and orbit of the moon, as well as the hours and minutes of the mean solar time. An Ellipse frames the portion of the sky visible from Geneva.
