Rotonde de Cartier Earth and Moon and the Rotonde de Cartier Astrocalendaire

Cartier watches style in Fine Watchmaking is the Maison’s creative approach for 2014. Style is a question of elegance and balance. It is the fountain-head of constant research, supported by technical expertise with a drive that redefines and questions watchmaking conventions by reinventing traditional complications such as the perpetual calendar or by transforming the timeless Tank model. Cartier’s achievements in Fine Watchmaking are the fruit of a constantly innovative approach at the service of highly distinctive aesthetics. Its past as an inventor and designer has given rise to a style that favors volume and shapes. The same drive can be seen in the Maison’s technical concepts: their freedom and importance have enabled Cartier to revolutionize the representation of time with Fine Watchmaking pieces that adhere to the Manufacture’s highest standards. For this 2014 edition of the Salon International de la Haute Horlogerie, Cartier expresses the excellence of its craftsmanship with the launch of innovative timepieces bearing the Maison’s creative seal.

The Rotonde de Cartier Earth and Moon watch is the fruit of a technical and creative ambition that for Cartier consists of bringing together two complications in a daring display. Removed from its strictly horological role, in which it serves as a guarantee of precision and prestige, a tourbillon has been incorporated into a moon phase complication, with each one dependent on the other. The watch owes its name to the stylized portrayal of the globe and the moon represented by a tourbillon. Together, they form a creative and animated world with skeletonized Roman numerals surrounding this dynamic feat of watchmaking. The moon-phase mechanism of the Rotonde de Cartier Earth and Moon watch is founded on a creative and complex design that combines a tourbillon, moon phase on demand and a second time zone.

The Tourbillon mechanism is a complex complication that falls within the expertise of a limited number of watchmakers. Its main function is to fight against the effects of gravity when the watch is in a vertical position. Because it appears in its original form and exists only when its user wishes it to, the moon phase on the Rotonde de Cartier Earth and Moon watch reveals a technical creativity that is doubly innovative. By pressing the push-button situated at four o’clock on the side of the case, a panels descends and partially obscures the Tourbillon carriage. The crescent thus formed reproduces exactly the moon’s shape in the

The second time zone of the Rotonde de Cartier Earth and Moon watch is indicated by a 24-hour disc that was entirely redeveloped by for the calibre 9440 MC due to the sophistication of its disc display. The result of painstaking work, polished lapis lazuli is used for the dial and the moon panel on the Rotonde de Cartier Earth and Moon watch. The hours and the second time zone are surrounded by a meticulously polished grid in 18-carat white gold. A three-dimensional dial is one of the signature features of the Cartier Fine Watchmaking collection, alongside Roman numerals that are openworked and chamfered by the hand of a master decorator in a manner akin to a skeleton movement. The exceptional finishes of the 9440 MC are all the more remarkable because the semi-skeletonized bridges on the back of the movement are structured in a star shape, echoing this precious timepiece’s lunar and terrestrial character on the case back. With the the Rotonde de Cartier Earth and Moon watch, the Maison Cartier has created a timepiece that displays an exceptional level of creativity and craftsmanship.
