Jacob & Co. Astronomia Fleurs de Jardin Diamond and Rose Gold Watch AS921.40

You don’t really just look at this watch. You watch it move. In this Fleurs de Jardin piece, gem-set flowers rotate across the dial in constant motion. A central axis, marked by a Jacob-cut Tsavorite gem, supports three rotating arms with the “Astronomia Solar” signature.. One carries a flying tourbillon completing a ten-minute rotation, while another holds a mother-of-pearl time display stabilized by a differential system so it remains upright as the mechanism turns. Beneath the main display, sapphire-set flowers spin in across multiple levels, adding continuous movement across the lower dial architecture. Its 43mm rose gold case features a dual-tier diamond-set bezel, utilizing a solid cylinder of sapphire crystal for the mid-case for an unobstructed lateral view of the highly mechanical composition driven by the manual-winding caliber JCAM31. The movement is wound via keys on the caseback and offers a 48-hour power reserve. This particular piece is numbered as one of only eighteen examples produced. In pre-owned condition, this Jacob & Co. Fleurs de Jardin Diamond and 18K Rose Gold Watch AS921.40 comes with a gift box.
