The Cartier Santos de Cartier Skeleton Large WHSA0028 showcases a bold architectural design with skeletonized bridges forming Roman numerals coated in green lacquer. Crafted in stainless steel, its 39.8 mm case reveals the manual-winding through sapphire crystals on both sides. Gray steel sword hands and a faceted crown set with a gray spinel complete this masterpiece—an artistic fusion of transparency, precision, and modern sophistication.
