A sapphire set on the winder: it's the signature of Cartier watches. This cabochon tells the story of the famous clockmaker-jeweler Paris, who has always walked on two feet : high technology and aesthetics. Thus Cartier became famous with mysterious clocks featuring works of art and with revolutionary timepieces. Most of these objects were animated by Swiss LeCoultre movements. Today, Cartier develops haute horlogerie movements in its La Chaux-de-Fonds factory, which explores new technological paths. But aesthetics is never forgotten; the watchmaking tradition is always coupled with a reflection on the shape and pleasure of the eye. We will discover it with this excellent book, which also serves as a catalog for an exhibition that runs in the major art museums of the planet.
