The Rotonde de Cartier minute repeater with flying tourbillon watch is the fruit of five years of research into the different characteristics of watch acoustics. Cartier’s Research and Development Department has thus taken up the challenge of offering lovers of fine watchmaking a minute repeater watch which, while remaining traditional in its design, represents a synthesis of in-depth acoustic research as applied to watchmaking. From the original design to the production and assembly of the 9402 MC movement, Cartier has used all its expertise to develop a watch that reveals all the details of these two major complications. The dial of the Rotonde de Cartier not only shows the motion of the tourbillon carriage but also the key components of the minute repeater: the movement is designed to give a continuous view of the flywheel, hammers and gongs.At the same time, the sapphire case back reveals the 447 components of the movement that is produced according to pure watchmaking tradition and meets the rigorous criteria of the Geneva Seal.
