Cartier Rotonde de Cartier Astromysterieux New Watch

The Cartier Rotonde de Cartier Astromystérieux watch is another highly limited and exciting “mystery” dial watch from Cartier fine watchmaking.The new Astromystérieux follows the creation of several Cartier mysterious watches and achieves a new feat by combining the central rotation of an escapement with the axis of the watch’s hands in the new caliber 9462 MC. Closer inspection of the caliber itself reveals that the mystery is enabled by the use of sapphire discs imperceptible to the naked eye.The cage is made up of a lower bridge in the form of a sapphire disc with a large diameter, together with two upper bridges, one of which holds the balance-wheel and the other the escapement, the geartrain and the barrel. Under this patented system, the crown is only linked to the barrel when it is being wound.  When the crown is turned to wind the mechanism, the pinion takes up a position in which it forms a connection with the winding disc. best replica Cartier Rotonde de Cartier watches


The connection between Cartier and mystery watches goes back to the first years of the 20th century when Cartier presented the famous mystery clocks.This solution was made possible by the development of a floating pinion between the crown’s winding shaft and the winding disc.Taking his inspiration from the clocks of the famous French illusionist Jean-Eugène Robert-Houdin (1805-1871), Couët developed the key concept: the hours and minutes hands are not directly linked to the movement.When the crown is not being used, the pinion disengages. A special system has been developed so that the crown’s winding shaft and the barrel cannot be broken in the event of excessive winding.It provides the motion required to make the tourbillon cage turn when the watch is running normally, and, when the crown is pulled out, it engages the time-setting system.replica Longines Flagship watches
