A true statement piece. The Santos de Cartier Skeleton features a fully exposed automatic movement through an open-worked dial, revealing the intricate gears and mechanics within. Framed by a bold yellow gold case with iconic exposed screws and a sapphire cabochon crown, this timepiece blends Cartier's legendary craftsmanship with raw mechanical art. The blued steel hands contrast beautifully against the skeletonized Roman numeral dial, making every second visible — literally.
