The movement in the Rotonde de Cartier Reversed Tourbillon is Cartier’s in-house Caliber 9458, visible through the watch’s clear sapphire caseback. The manual-wound tourbillon movement is made up of 167 components, including 19 jewels, and has a frequency of 21,600 vph and power reserve of approximately 52 hours. All of its pieces are hand-finished, boasting such high-horology details as chamfering on the bridges, drawn flanks, polished screw heads and a parallel cotes de Geneve motif on the mainplate that echoes the radiating lines on the dial. Like other Cartier movements of recent vintage, Caliber 9458 has been awarded the poinçon de Genève, or Geneva Hallmark, for meeting the 12 criteria of excellence in movement finishing. Cartier says that the price of the Rotonde de Cartier Flying Tourbillon, will be 110,000 euros.
Today at the SIHH in Geneva, I had the chance to try on the Cartier Rotonde de Cartier Reversed Tourbillon for myself and was suitably impressed. Below is a glimpse of how it looks on the wrist.
