The Rotonde de Cartier Reversed Tourbillon watch gets its name from the topsy-turvy arrangement of its movement. Despite the ubiquity of tourbillons that are visible from the dial today, the complication was originally mounted closer to the case back and hidden from view. This watch’s flying tourbillon’s placement, however, has been “reversed” to the dial side, along with the mainspring and gear train.These components are layered out of necessity, with the blued steel hands closest to the crystal, followed by the various wheels, bridges, and springs, and other components. This creates a delightfully layered appearance that must be appreciated in person, preferably with a loupe, in order to observe the dial from different angles. Because of this visual interest created by the movement components, they have been elevated to become the central element of the dial. The relatively simple guilloché dial takes a backseat on this watch, and serves to accentuate the perception of depth on the watch face.This isn’t Cartier’s first Reversed Tourbillon watch from the Rotonde de Cartier collection though. The original, introduced and formerly known as the Cadran Lové Tourbillon watch, set the precedent in 2012 with its layered dial, off-centred layout, and second hand in the form of a capitalised “C”, as shown below. Besides these visual similarities, the newer iteration also retains the Calibre 9458 MC movement. The manual-winding flying tourbillon movement comes packed with a 50-hour power reserve, and clocks in at a wide 16¾ lignes. Naturally, the case remains unchanged at 46mm wide to accommodate it – certainly a tad too big to qualify as a dress watch, but an appropriate size for its purpose, which is to display the watch’s details in all their glory. Like the original, the new Reversed Tourbillon is certified Côtes de Genève due to the finishing standards on the movement.
