At SIHH previous week Cartier launched the brand new Rotonde de Cartier Astrotourbillon with their new handbook winding motion, Caliber 9451 MC, made and made by Cartier watchmakers. This strange movement could be the item of five yrs of advancement for the Cartier Manufacture in La Chaux-de-Fonds.
The Astrotourbillon's carriage is pushed by the 3rd wheel on the gear practice . The pinion with the escape wheel rotates around a hard and fast seconds-wheel (the fourth wheel from the gear teach) in an effort to travel the escapement. The carriage features a exclusive rotational axis, as it is positioned with the heart of the movement. This demands a unique gear-train style and design, in the two barrels of your motion by into the exhibit of the minutes and hrs. Yet another characteristic, to blame for the putting visual influence established via the motion, is the fact that the harmony staff members and escape-wheel personnel usually are not around the similar rotational axis as the carriage. They are located to at least one side in the carriage, in linear alignment with its rotational axis. The tourbillon carriage is positioned earlier mentioned the motion in between two dials, rather than getting straight built-in into your movement as with classic tourbillons.
This development is strange and has both aesthetic and specialized outcomes. The elongated carriage helps make an entire revolution all around the complete area in the dial in one minute. The off-center equilibrium bridge, formed like an arrow, indicates the seconds. In an effort to make sure the equilibrium on the carriage, it was essential to incorporate a platinum counterweight to the opposite aspect of the carriage, hidden underneath the central dial. Moreover, the load of the carriage needed to be minimal (0.39 g with the total carriage, excluding the counterweight) so that you can regulate its inertia all through rotation, consequently the selection of titanium for its construction.
This new motion is housed during the forty seven mm Rotonde de Cartier situation, gold breitling accessible in white or rose gold, priced as follows:
White gold, Ref. CRW1556204 - $133,000
Rose gold, Ref. CRW1556205 - $124,000
