Imagine owning a watch so mesmerizing that it seems the laws of gravity have been rewritten just for it. Welcome to the world of the Cartier Rotonde Tourbillon Mysterieux—where the magic of engineering meets the art of time.

Crafted by Cartier’s master watchmakers, the Rotonde Tourbillon Mysterieux features a sapphire crystal disc treated to reduce glare. A hole, precisely the size of the tourbillon, is carved in the disc, creating the illusion of the tourbillon frame suspended in mid-air. This masterful effect is achieved by keeping the disc itself rotating while power is seamlessly delivered to the tourbillon.

The key lies in the sapphire disc’s edge, where a gear train connects to a larger gear rotating once per minute. This elaborate mechanism, housing an independently crafted manual winding mechanical movement, is a testament to the watchmakers’ relentless pursuit of perfection.

Each mobile component’s speed was calculated multiple times to minimize energy consumption. The tourbillon frame, weighing just 0.28 grams, completes one rotation every minute within its designated space. Components, including the sapphire disc and titanium tourbillon frame, have been meticulously lightened to control inertia.

A dynamic balance is struck using a K-gold round frame mounted opposite the tourbillon, offsetting the weight of the regulating mechanism and tourbillon frame. The weight distribution creates a harmonious balance that contributes to this ‘floating’ effect.

Housed in a 904 steel case, the watch boasts a 45mm diameter, platinum bead-shaped crown with a convex natural spinel, and sapphire crystal case back. It’s water-resistant to 30 meters (100 feet, 3 bars).

The elegant deep grey electroplated dial features silver plated openwork grilles with sunburst effects and black Roman numerals. Blue sword-shaped hands and an Italian calfskin strap complete this masterpiece, held together by an original steel folding clasp.

The Cartier 9454 MC caliber manual winding mechanical movement, engraved with the “Geneva Quality Hallmark,” powers the double tourbillon. With 25 ruby jeweled bearings, 242 parts, a balance frequency of 21,600 vibrations per hour, and a 42-hour power reserve, this watch is not just a timepiece; it’s a revelation.

Each watch is given a unique code, with early orders allowing buyers to select their lucky number. So, if you’re in the market for a magical masterpiece, consider this your invitation to embrace the mystique.
