Cartie (Cartier) presented the world’s first Cartier ID One concept watch without adjustment and lubricants in 2009, which caused many surprises. In 2012, the brand will launch the famous movement Astrotourbillon astronomical tourbillon movement first introduced two years ago on the ID One concept watch and launch the Rotonde de Cartier Astrotourbillon astronomical tourbillon carbon crystal watch. Thanks to its tourbillon escapement, which requires no adjustment and no lubricant, the new watch marks the first step in mass production with ID One technology.
Since the era of ID one, we can’t avoid the extraordinary forward-looking nature of Cartier. This astronomical tourbillon carbon crystal watch will reflect this impression to the extreme. Uncover the mystery of this watch.
The 47mm Rotonde de Cartier case is made of a niobium-titanium alloy, which is lighter in weight and has magnetic resistance and strong resistance to corrosion, scratches and shock.
The watch uses a carbon black dial, the tourbillon rotation axis is placed in the center of the dial, hours, minutes and Roman numerals, which is one of Cartier’s classic elements.
The bead-shaped crown is set with a convex round sapphire. The watch is equipped with a black alligator leather strap and 18K white gold folding buckle, which is waterproof to 30 meters.
The watch is equipped with a Cartier 9460 MC manual winding mechanical movement equipped with a tourbillon bridge, an escapement fork and an escape wheel, all of which are made of carbon crystal material. Due to the use of deep reactive ion etching (DRIE) technology, carbon crystal parts have achieved ultra-high precision of one thousandth of a millimeter (that is, 1 micron) and have extremely smooth surfaces. It fits perfectly with the escape wheel during assembly and does not require any lubricant at all.
In addition, in an unprecedented application, Cartier also made a pivot with an ultra-hard tungsten carbide ceramic, which was coated with a smooth diamond coating. The pivoting shaft inside the carbon crystal holder thus minimizes friction and requires no lubricant. The movement vibrates 21,600 times per hour (3 Hz) and has a 50-hour power reserve.
Astrotourbillon was also selected as the first carbon crystal model. The tourbillon bridge was originally very large, but because the carbon crystal was very light, the weight of the tourbillon itself was significantly reduced. With the use of carbon escapement wheels and pallet forks, the resulting weight reduction means less kinetic energy required and less torque.
Because Astrotourbillon carbon crystal is a non-magnetic material, the watch is not easily interfered by magnetic fields and has a certain anti-magnetic property.
Summary: Cartier has challenged people’s traditional perception of watches with exquisite craftsmanship and absolute cutting-edge technology. This challenge requires not only the courage to surpass, but also a confidence in the strength of the brand . Although the frictionless movement of the high-tech materials mentioned above cannot reach the point of mass production in a short period of time, I believe that such a forward-looking vision will definitely determine the limitless future of the watch industry.
