For decades, traditional horology operated on a strict divide: the exterior of a watch was for the designer, and the interior was for the engineer. Skeleton watches—timepieces with their dials cut away to reveal the inner mechanics—were often just standard movements hollowed out as an afterthought.
Cartier didn’t just break this rule; they rewrote it.
By engineering their manufacture movements to serve as the actual dials, Cartier has transformed the skeleton watch from a mere technical display into a canvas for modern architectural art. From the iconic Santos to the avant-garde Asymétrique, here is the complete collector’s guide to modern Cartier skeleton watches.
The Core Collection: Santos de Cartier
If you want to understand Cartier’s modern skeleton philosophy, you have to look at the Santos de Cartier collection. Rather than suspending a small movement in the center of a large square case, Cartier’s engineers designed the baseplates and bridges of the Caliber 9611 MC to act as the primary hour markers. The bridges form massive, structural Roman numerals (III, VI, IX, and XII) that anchor the movement directly to the case.
There are currently six distinct executions in the modern catalog:
- The Purist’s Choice: The classic all-steel WHSA0028 (and its predecessor WHSA0015) offers a clean, monochromatic industrial look that highlights the blued-steel sword hands.
- The Two-Tone Revival: The WHSA0019 brings 18k yellow gold to the bezel, perfectly warming up the steel architecture.
- The Ultimate Flex: The WHSA0016 casts the entire case and bracelet in solid 18k Rose Gold, creating a stark, luxurious contrast against the rhodium-finished movement. (Cartier also produces an 18k Yellow Gold counterpart, the WHSA0024).

- The Stealth Execution: For a completely different vibe, the WHSA0009 coats the steel case in Black ADLC (Amorphous Diamond-Like Carbon), creating a sporty, luminescent stealth-wealth aesthetic.
- High Jewelry: Cartier also offers several ultra-exclusive, factory diamond-set “Iced Out” variations of the Santos Skeleton for elite clients.

The Aviation Tribute: Santos-Dumont
While the standard Santos models utilize manual-winding calibers to keep the watches as thin as possible, the Santos-Dumont Micro-Rotor introduces a brilliant automatic solution.
Powered by the 9629 MC caliber, this watch replaces the standard oscillating weight with a functional micro-rotor crafted into a miniature replica of the Demoiselle—the aircraft designed by Alberto Santos-Dumont in 1907. As you move your wrist, the tiny gold plane spins to wind the mainspring. The collection features three models.

- Rose Gold (WHSA0030): The warmest execution, featuring striking burgundy lacquer on the bridges. Read our full deep-dive on the Santos-Dumont Micro-Rotor here.
- Steel (WHSA0031): Features blue lacquer on the bridges.
- Two-Tone (WHSA0032): Blends a steel case with yellow gold accents.
Where Bridges Become Arabic: The Pasha
Taking the same structural concept from the Santos but applying it to a round case, the Pasha de Cartier Skeleton proves the versatility of Cartier’s design team. Here, the bridges form an oversized Arabic numeral layout (3, 6, 9, 12), contrasting brilliantly against the inner square minute track that defines the Pasha’s unique “square inside a circle” design language.
The modern Pasha skeleton lineup consists of four distinct tiers:
- Steel (WHPA0017): The classic, monochromatic steel execution.
- Rose Gold (WHPA0018): The precious metal execution.
- Black ADLC (CRWHPA0017): A sporty, aggressive execution with a black-coated steel case.
- Flying Tourbillon (W3030021): An extreme Haute Horlogerie execution in white gold featuring a flying tourbillon complication.
The Shape Rebels: Tank Cintrée & Asymétrique
Cartier’s Privé collection represents the absolute pinnacle of their horological artistry. Because skeletonizing a shaped watch requires custom-engineering the movement to fit the exact geometry of the case, these are produced in fiercely limited numbers.
The Tank Cintrée
The Cintrée is famous for its elegant curvature. To celebrate the Tank’s 100th anniversary, Cartier produced a highly limited run of skeleton models across three variations, utilizing a custom curved caliber that echoes the sweeping lines of the case while suspending the gear train in mid-air.
- Rose Gold (WHTA0008): Limited to just 100 pieces globally.
- Platinum (CRWHTA0009): Limited to 100 pieces.
- Platinum Diamond-Set: An ultra-rare, high-jewelry execution.
The Tank Asymétrique
Originally designed in 1936 to allow drivers to read the time with their hands on the steering wheel, the Asymétrique features a distinct 30-degree rightward tilt. In its modern skeletonized form, the manual-winding 9623 MC caliber is suspended within the parallelogram case. The catalog features three 100-piece limited editions in platinum and rose gold.
- Platinum (WHTA0012): Suspends the movement using striking blue-lacquered bridges that perfectly match the blued-steel hands.
- Rose Gold (WHTA0011): Warms up the aggressive parallelogram geometry with the classic elegance of 18k Rose Gold bridges.
- Platinum Diamond-Set: A high-jewelry iteration with a diamond-set case.
The Takeaway: Cartier’s modern skeleton lineup proves that a watch doesn’t have to choose between being a piece of jewelry and a serious horological instrument. By fusing the two, Cartier has secured its position at the absolute pinnacle of contemporary watchmaking.
