The Reference 6102, a Patek Philippe astronomical Grand Complication, presents several functions that are exceptionally uncommon in a wristwatch. It permanently showcases the heavenly canopy over the northern hemisphere, emulating the apparent movement of the stars as well as the positions and phases of the moon in the course of a lunar cycle. This fascinating celestial ballet is choreographed by the self-winding caliber 240 LU CL C movement, which despite its complexity is only 6.81 mm high. The astronomical indications are complemented by a central date hand that points at the date scale on the outermost periphery of the sapphire-crystal.
