2013 Geneva Watch Exhibition Rotonde De Cartier Double Mysterious Tourbillon Watch

Cartier as a veteran brand of SIHH, this time also brought a number of new products of its own debut, this time for everyone is a Cartier dual tourbillon watch, the next watch home Live updates on the latest press conference for everyone. (Pictures from foreign websites)

   Imagine a watch with a tourbillon device suspended in the air-Cartier has turned this dream into a reality with the new 9454 MC dual mysterious tourbillon movement and won the Geneva Quality Seal. A little closer inspection reveals the magic of this mechanism. The floating tourbillon, which rotates once every 60 seconds, seems to be completely suspended in the air, without any connection to other components. When the tourbillon frame starts its second rotation every 5 minutes a week, this magical visual experience is finally achieved. This dual mysterious floating tourbillon watch not only combines Cartier’s bold creativity and watchmaking expertise, but also embodies the essence of the brand’s mysterious timepiece creation for more than a century.

   Behind the simple and elegant appearance hides incredible complex machinery. The biggest highlight of this Rotonde de Cartier watch is the innovative mechanical structure called ‘double mystery’. The watchmaker at the Cartier Workshop must show endless originality and flexibility in order to maximize the materials and movement and create a series of dazzling dynamic miracles. When performing tricks, magicians need to divert the audience’s attention and convince them of the visual illusions and supernatural powers they create. In the Rotonde double mysterious tourbillon watch, the designer team draws inspiration from the creativity of Jean-Eugène Robert-Houdin, the father of modern magic, to create a suspended visual feast.

 
   Experts in the watchmaking industry know that the tourbillon device in the vertical position rotates at a predetermined frequency through its frame, and the average azimuth error (by passing through each point of the circle in a given time), thereby reducing the gravity to the balance wheel (Regulatory mechanism). This exquisite device is placed in the center of the Rotonde double mysterious tourbillon watch, which seems to get rid of the law of gravity, giving people the impression of being unsupported and suspended in the air. At the same time, the tourbillon frame completes one rotation per minute and complete rotation in its space every 5 minutes, completely released from the constraints of gravity.

  
   The watchmaker at Cartier’s workshop uses an anti-glare sapphire crystal wafer disc and excavates a hole the same size as the tourbillon, thereby perfectly creating the illusion of the tourbillon frame hanging. In order to realize this illusion, they made the disc supporting the frame in a rotating state, and then set the minute wheel driving the vibrator on a rotating shaft, which was used to limit the inherent ‘resistance torque’ of the mechanism supporting the tourbillon, and was successful. The power is transmitted to the tourbillon, and the entire device can complete a suspended rotation every 5 minutes. Therefore, while the tourbillon rotates every 5 minutes in a transparent open space, its frame performs 5 complete rotations. The secret to achieving this is to place a set of racks around the edge of the sapphire crystal wafer disc, connecting the disc to a large gear that runs once every 5 minutes.

   The 9454 MC dual mystery tourbillon movement is the result of Cartier’s long-term research and development. For example, determining the speed of each moving part requires countless calculations. To minimize energy consumption, the tourbillon frame completes a complete rotation in its specific space every 5 minutes, which is 25 times less energy than a revolution per minute. In order to improve the efficiency of this mobile device, the weight of each component of the movement is minimized, so as to better control the inertia of the rotating components including the disc and the titanium tourbillon frame. Although the weight of the ‘floating’ frame has been reduced to a minimum (0.28 g), in order to compensate for the weight of the speed governing mechanism and the frame, a part of the round frame for meshing the gear is made of gold and is installed opposite the tourbillon. Position to equalize weight on both sides, creating a dynamic balance effect.
                      I believe this watch must be expensive

Summary: From the bottom of my heart, Cartier is the most eye-catching brand at the Geneva Watch Fair. A number of ultra-avant-garde watches have attracted the attention of countless media, including this dual tourbillon The world announced Cartier’s unshakable watchmaking power, and as a watch enthusiast, how can there be too much power for such a challenging watch?
