Five new movements and nine new models unveiled at Geneva watch show.
A “rush of creative energy” over the past two years has resulted in Cartier unveiling five new fine watch making movements and nine new models – all unveiled on Monday at the Salon International del la Haute Horlogerie.
Star of the 2010 collection is the Rotonde de Cartier Astrotourbillon watch, in which Cartier incorporates a new movement, the 9451 MC, that has taken five years f design and production work Cartier master watchmakers to bring to market.
The movement incorporates a tourbillon carriage containing the various organs of the escapement and sprung balance, and is positioned above the movement between two dials, rather than being directly integrated into the movement as with classic tourbillons.
This construction is highly unusual for a central tourbillon and has both aesthetic and technical consequences. Visually, the elongated carriage makes a complete revolution around the entire surface of the dial in one minute.
The off-centred balance bridge, shaped like an arrow, indicates the seconds. Technically, in order to ensure the equilibrium of the carriage, it was necessary to incorporate a platinum counterweight on the opposite side of the carriage, hidden under the central dial.
The effect of this technical innovation is hypnotic as the tourbillion sweeps around the dial spinning circles within circles.
In the extra-large, 47mm diameter Rotonde de Cartier watch, the innovation and design come together to create a piece that is formidable in scale, but intoxicating in its complexity.
