Like previous models in the series, the 18K rose gold skeleton case of the Jacob & Co. Astronomia Maestro Worldtime is designed to showcase as much of the intricate workings of the movement as possible. To this end, the massive 50mm-wide, 26mm-thick frame is laid out primarily as a cylindrical sapphire box with a gold structural chassis. While the proportions and materials at play make the case a visual spectacle of its own, the visual focus is kept squarely on the movement and dial in initial images. Despite the hefty proportions, the actual lines of the case are simple and elemental, with clean vertical case sides and sharply sloping curved skeleton lugs. To maintain this clean high-visibility look, the Astronomia does not have a traditional crown, with winding and setting functions moved to the solid caseback
