In response to a request from a client who collects both luxury cars and fine watches, Vacheron Constantin, the Manufacture has created a unique timepiece designed to fit into the dashboard of an exquisite Rolls-Royce Coachbuild commission - the Rolls-Royce Amethyst Droptail. Working closely with the British luxury house on the technical specifications and finishing details, Vacheron Constantin developed this single-edition Les Cabinotiers Armillary Tourbillon timepiece to perfectly complement the Rolls-Royce Amethyst Droptail’s interior suite. Designed to be displayed on the dashboard, which is finished in Calamander Light open pore wood veneer, the timepiece is housed within an elegant, fully integrated yet removable holder mechanism.
