Cartier created a new watch displays for SIHH 2016-The new Rotonde de Cartier Astromystérieux.
The new Astromystérieux follows the creation of several Cartier mysterious wristwatches and achieves a new feat by combining the central rotation of an escapement with the axis of the watch’s hands. To obtain this exceptional result, the space dedicated to the movement’s non-visible gearings has been reduced to the strict minimum.
The architecture of the 9462 MC calibre is characterised by the elongated shape of the central mechanism representing the minutes hand. Comprising the escapement, balance wheel, gear train and barrel and with no apparent connection with the rest of the movement, this mysterious tourbillon completes a full turn of the dial in one hour.
This central mechanism acts in a similar way to the flying cage of a traditional tourbillon with the difference that it encloses not only the escapement and balance-wheel, but also the geartrain and barrel.This 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.
The Rotonde de Cartier Astromystérieux watch comes in a 950/1000 palladium case with a diameter of 43.5 mm and a total thickness of 12 mm. It will be produced in a limited series of 100 numbered pieces. cartier will announces its price at the 2016 Salon International de la Haute Horlogerie.
