Cartier presented to the world in 2009 a first Cartier ID One concept watch that requires no adjustment and no lubricant, which has 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.
The first Cartier ID One concept watch requiring no adjustments and no lubricant
Watch with Cartier 9460 MC manual winding mechanical movement
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.
The new watch marks the first step in mass production of ID One technology. Limited edition of 50 pieces.
