Santos de Cartier Skeleton Watch Ref. WHSA0009 - Extra Large

The Santos de Cartier Skeleton, reference WHSA0009, is the blacked-out version of Cartier's openworked Santos, with the case finished in black ADLC over steel. This is the Noctambule, which means the skeletonized bridges that form the Santos Roman numerals are filled with luminescent material, so the time glows in the dark. The seven-sided crown is set with a blue synthetic spinel, the one flash of colour against the all-black case.

It is the large model, 39.7mm wide, and it runs the hand-wound calibre 9612 MC, an individually numbered movement with 138 parts, 20 jewels, and about 72 hours of power reserve, visible front and back through sapphire. Grey steel sword hands track across the open structure. It comes with two alligator straps, black and dark grey, both fitted with Cartier's QuickSwitch system so they change over without tools.

This one is new, a 2021 watch with its box and original papers. At Konesseur, every Cartier is authenticated and inspected in Dubai before listing, and the UAE's 5% VAT keeps a piece at this level below European retail. See the full Santos line or browse more Cartier to compare finishes.
