Cartier Masse Mystérieuse: magic in the making
Watchmakers are said to be the masters of time. In some cases, as with the Masse Mystérieuse de Cartier, they prove to be prestidigitators capable of seducing the eye to the point of making amateurs with a knowledge of classical mechanics lose all their bearings. Discover it!
As the head of development at Cartier said during the presentation: ‘At the heart of the Maison, time is not limited to being an objective datum. It is above all the basic element, constantly explored by the craftsmen eager to extract its quintessence’. From this permanent quest was born, 8 years ago, the desire to push back the limits of mechanics even further by having the spring and the primary gearing of a calibre inscribed in the mass intended to maintain its winding. This was a major challenge and part of a spectacular design logic requiring the team in charge of its development to understand the strengths and perfect mastery of watchmaking knowledge.
For this marvel, produced in a limited edition of only 30 pieces and fitted with a platinum case measuring 43.5 mm in diameter, two of Cartier’s specialities have been combined: skeletonisation of the movement and mysterious operation. Proof of the excellence of this combination is the fact that it is practically impossible, even for a qualified watchmaker, to guess how the movement included in the mobile mass, christened 9801MC, manages to wind itself without the hands displaying the time being disturbed and the chronometry being put at risk.
This calibre, which appears to be weightless and required five successive iterations to function perfectly, is widely openworked to allow the eye to try to follow the ultra-complicated kinematic chain designed to move the hands. The latter are associated with an ultra-sophisticated differential in order to maintain their position at all times, despite the movements of the wearer.
In addition, and this is not immediately obvious, the motor rotor, which is mobile and active in both directions, has been designed in such a way as to keep the balance wheel in a vertical position. A way to guarantee the precision of the instrument by ensuring great stability to the oscillator. What better way to innovate?
