The 45 mm case, with a thickness of 12.4 mm, is crafted entirely from 18K rose gold, including the bezel, lugs, and crown. The case surfaces are mirror-polished to a radiant finish, while the sharply defined lugs lend a touch of architectural precision. The fluted crown is set with a signature cabochon-cut blue sapphire, a hallmark of Cartier’s watchmaking aesthetics.9

At 6 o’clock, the centerpiece of the composition—the Double Mysterious Tourbillon—commands attention. This ingenious mechanism mounts the tourbillon carriage on a sapphire crystal disc, which itself completes a full rotation every five minutes, while the tourbillon cage makes its own revolution every 60 seconds. The result is a breathtaking illusion of the tourbillon floating freely in midair, seemingly disconnected from any mechanical linkage.

Inside beats the Caliber 9465 MC hand-wound movement, operating at 21,600 vibrations per hour with a 52-hour power reserve. Viewed through the sapphire crystal caseback, the intricate gear train and tourbillon system reveal the technical mastery and decorative refinement of Cartier’s haute horlogerie.
