Les Cabinotiers Armillary Tourbillon - The Guillochage

The attention devoted to details and finishing demonstrate the meticulous care lavished on the project by the Rolls-Royce Coachbuild and Vacheron Constantin teams. The sapphire dial of the timepiece reveals the full beauty of Calibre 1990, including a mainplate featuring a mauve-coloured NAC galvanic coating with a circular satin finish – an original shade matching the hue of the Rolls-Royce Amethyst Droptail’s leather seats. On the dial side, the bridges are sharply cut, hand-bevelled and adorned with a Côtes de Genève pattern also found on the rear-side bridges in the same mauve colour. The holder was also designed to be removed from its housing if necessary and to allow the watch to be rotated through 180° for setting, winding and admiring the reverse of the calibre. The holders’ slightly curved outer frame is made of polished steel, with a bevelled steel inner frame laser-textured with a black PVD coating. The base watch is affixed to a white gold base-plate, adorned with a hand-crafted sunburst guilloché motif featuring an applied Maltese cross. The holder can be covered with a steel lid, secured with a Maltese cross-shaped lock. When the watch and holder are removed from the dashboard and placed in their box, an identical empty holder takes its place.
