Cartier Rotonde De Cartier Astrotourbillon, Reference 3307 A white gold tourbillon wristwatch, Circa 2011 卡地亞 ROTONDE DE CARTIER ASTROTOURBILLON 型號3307 白金陀飛輪腕錶，約2011年製 Dial: silvered Calibre: cal. 9451 MC mechanical, 23 jewels Case: 18k white gold, sapphire crystal display back secured by 8 screws Case number: 40 Closure: black Cartier alligator strap and 18k white gold folding clasp Size: 46.5 mm diameter Signed: case, dial and movement Accessories: Cartier Certificate, loupe, instruction manual and presentation box 附帶證書、放大鏡、説明書及盒子 The Calibre de Cartier collection introduced an Astrotourbillon in 2011, named after its advanced tourbillon component which orbits the dial once a minute, relying on a manually wound movement. The addition of a tourbillon to the face of the watch exhibits the complexity that powers the present Calibre de Cartier wristwatch. Otherwise, the layout of the dial remains relatively simple, with only an adornment of Roman indexes - a classic choice of Cartier’s - around a clean silver dial. Furthermore, the blued hands can stand out further through the elevated centre piece of the dial as they hover over the hour and minute track, bearing the Cartier tradition while boldly moving into the future.
