Rotonde de Cartier Minute Repeater Mysterious Double Tourbillon

For the first time, the magic of Cartier's mysterious movement, introduced in 2013, meets the mechanical complexity of a minute repeater. The Rotonde de Cartier Minute Repeater Mysterious Double Tourbillon represents a twofold challenge. In addition to the technical feat of assembling 448 components in a case measuring a mere 11.15 mm, the timepiece is aesthetically stunning, as the openwork mechanism and contrasting black rhodium finish expose the transparency of the mysterious double tourbillon. This complication is unique to Cartier, whose mystery clocks of the early twentieth century stand out in horology's history. The flying tourbillon, which completes one rotation every 60 seconds, appears to be suspended, as though unconnected to the movement. The illusion is made greater still by the sapphire disc on which the tourbillon is mounted, and which makes its rotation in five minutes.
