Cartier Santos de Cartier WHSA0016 39.8mm 9611 MC Movement Skeleton Watch
The Santos de Cartier WHSA0016 combines one of the most recognizable square watch profiles with an intricate full-skeleton display. Its rounded-square case, exposed screws, integrated metal bracelet, and architectural dial create a distinctive balance between refined jewelry design and confident sports-watch character.
The openworked dial reveals the movement’s gears, bridges, and transmission components, while the dark gray Roman numerals are incorporated directly into the movement structure. Sword-shaped hands remain visually clear above the mechanical framework, creating depth without making the overall design feel excessively complicated.
A rose-gold-tone case appearance adds warmth and contrast to the exposed mechanism. Measuring 39.8 × 39.8mm, this manually wound mechanical watch offers a bold wrist presence while preserving the elegant proportions associated with the Santos design.

Movement
The watch is powered by a 9611 MC manual-winding mechanical movement. Unlike an automatic watch, it is wound by turning the crown manually, providing a direct and traditional connection between the wearer and the mechanism.
The skeleton construction allows the movement’s gears, bridges, and operating components to remain visible from the dial side. The Roman numeral structures are incorporated into the openworked framework, giving them both a visual and architectural role.
For daily use, wind the crown slowly until clear resistance is felt, and do not force it beyond that point. Actual accuracy, winding frequency, and power reserve may vary according to movement regulation, usage, and maintenance condition.
Materials
The case is listed as 316L stainless steel and presents a rose-gold-tone appearance. Its rounded edges and exposed screw details reinforce the distinctive Santos aesthetic while maintaining a refined jewelry-inspired finish.
The integrated bracelet is also made from stated 316L stainless steel. Its connected construction creates a continuous transition from the case to the wrist and gives the watch a solid yet polished presence.
A sapphire crystal protects the openworked dial and provides a clear view of the mechanical structure. As with any finished metal watch, direct contact with hard surfaces, chemicals, perfume, and salt water should be minimized to help preserve its appearance.
FAQ
1. How often does the watch need to be manually wound?
The required winding frequency depends on the movement’s actual power reserve and regulation. For regular use, wind the crown slowly before wearing the watch and stop when noticeable resistance is reached.
2. Are the Roman numerals printed on the dial?
No. The Roman numerals are integrated into the skeleton movement framework, allowing them to function as part of the watch’s architectural openworked design.
3. Is the skeleton dial difficult to read?
Skeleton watches are visually more complex than traditional solid-dial watches. However, the sword-shaped hands and dark gray Roman numeral structure provide contrast above the exposed mechanical components.
4. How does the 39.8mm square case wear on the wrist?
A square case generally has a stronger wrist presence than a round case with a similar measurement. The 39.8 × 39.8mm dimensions are best suited to customers who prefer a noticeable luxury statement rather than an understated profile.
5. What kind of water exposure can this watch handle?
Suitable only for light daily splashes, such as hand washing and rain. Do not swim, shower, sauna, or soak with the watch. Heat and steam may damage the waterproof gaskets. Replacing the gaskets every two years is recommended.
