To simplify the final assembly of the different components as much as possible, Cartier has adopted a modular approach that divides the movement into two separate parts: the movement movement, which occupies a crescent-shaped space on the main plate; and Independent display modules that occupy a circular space deliberately set aside. The solid composition consists of four anti-glare-treated sapphire crystal discs, each assembled one by one in a clean environment to avoid any dust. When the watch is finally assembled, the hands appear to float in the air as if by magic. By dedicating 58% of the movement’s diameter to the sapphire crystal disc, Cartier pushes the boundaries of magical displays and takes readability to a whole new level.

Thanks to the sapphire crystal disc, mystery display watches are often considered more delicate than traditional complicated movements. The innovative design of the calibre 9981 MC allows it to endure a series of rigorous tests, including 500 consecutive impacts and a one-meter drop to the ground. This remarkably clear movement is highly stable and precise, with a balance that oscillates at a frequency of 4 Hz (28,800 vibrations per hour) and a power reserve of 48 hours.

The balance and symmetry of the Rotonde de Cartier’s mysterious watch captivate you, infusing every detail with its transparent charm. In fact, the individually numbered hand-wound mechanical movement components visible on the back of the model are just one aspect Cartier wants to showcase. In the past, Louis Cartier had refused to explain to salespeople how the mysterious clock worked, to avoid the secret being leaked. Today, in the Rotonde de Cartier mystery watch, the mechanism that connects the movement and the hands is cleverly designed to remain hidden and unnoticed, thus preserving the magic.
