Celestial bodies and space exploration have long driven Jacob Arabo's creativity. In 2014, he translated his intimate passion into the ambitious Astronomia concept, a wrist-sized model of a planetary system and its constant motion. Astronomia Maestro is the most complex iteration of the original concept, with a higher degree of celestial realism. The Astronomia Maestro case is designed like an astronomer's observatory. A vast sapphire dome on top and a streamlined gold frame surround a single-block, full sapphire caseband. Their transparency offers a galaxy-wide view. Astronomia Maestro is a celebration of space, at a level of complexity and beauty that makes it unique. Astronomia Maestro features the Milky Way, hand-painted on the blue and starry aventurine base. It features an astronaut, floating in zero gravity, exploring the inside of the rotating movement. It showcases the largest Earth, rotating along, and a diamond-moon. And for once in the Astronomia collection, the hour and minute dial sits in the middle, above it all. It signifies that the passing of time is the maestro of us all.
