The JCAM19 powers the Astronomia Solar collection, featuring a three-arm carrier system (unlike the four-arm design of other Astronomia models) that rotates once every 10 minutes—twice as fast as previous models. The central 1.5 carat citrine with 288 facets represents the Sun. A flying tourbillon and hand-engraved enameled titanium Earth globe complete the celestial display. The aventurine base features all eight planets of the Solar System. With 447 components and a higher 4Hz frequency than earlier Astronomia movements, this represents an evolution in the collection's technical sophistication.
