Cartier - Astrotourbillon

A classical design with majestic
proportions. Rotonde de Cartier
watches encases the mysteries of the
most sophisticated movements.

The Astrotourbillon's carriage is driven by the third wheel of the gear train. The pinion of the escape wheel rotates around a fixed seconds-wheel in order to drive the escapement. The carriage has a special rotational axis, as it is positioned at the center of the movement. This requires a different gear-train design, from the two barrels of the movement through to the display of the minutes and hours. Another feature, responsible for the striking visual effect created by the movement, is that the balance staff and escape-wheel staff are not on the same rotational axis as the carriage. They are located to one side of the carriage, in linear alignment with its rotational axis. The tourbillon carriage is positioned "above" the movement between two dials, rather than being directly integrated into the movement as with classic tourbillons.

Fantastic idea!
