The Astronomia Solar transforms the wrist into a living model of the solar system, demonstrating Jacob & Co.‘s remarkable ability to merge scientific inspiration with uncompromising haute horlogerie. At its centre sits a handcrafted representation of the Sun, surrounded by orbiting planets that move continuously around the dial in carefully calculated cycles. Rather than simply displaying the time, the Astronomia Solar creates an immersive astronomical experience that celebrates humanity’s fascination with celestial mechanics through an extraordinary three-dimensional construction beneath its signature sapphire crystal dome.

Driving this mechanical universe is a highly sophisticated manufacture movement developed exclusively for the Astronomia collection. The rotating platform carries a high-speed flying tourbillon, an inclined time display and miniature planetary sculptures, all synchronised through an exceptionally complex system of precision gearing. Every component is individually hand-finished, polished and assembled to the highest standards of Swiss watchmaking, making the Astronomia Solar one of the most technically ambitious and visually captivating luxury timepieces ever created.
