Cartier Santos De Cartier – WHSA0009

Cartier Santos de Cartier Skeleton WHSA0009 is a bold, architectural timepiece that reimagines one of the world’s first wristwatches with a modern, openworked aesthetic and high-performance materials. This large model features a 47.5 × 39.7 mm case crafted from black ADLC-coated stainless steel, giving it a stealthy, matte finish that contrasts beautifully with the polished gray steel sword-shaped hands. The standout skeletonized dial transforms the Roman numeral hour markers into structural bridges, revealing the manual-winding caliber 9612 MC—a Cartier manufacture movement composed of 138 parts and 20 jewels, beating at 28,800 vibrations per hour with a 72-hour power reserve.
