Originally developed in 1931 and updated in 1959, Le Corbusier's Architectural Polychromy was a groundbreaking work that helped usher in a uniform system for color use in architecture. Now Rado is celebrating that legacy with the Les Couleurs Le Corbusier Collection. Based on their True Thinline model, the collection includes watches in nine unique hues: Cream White, Grey Brown Natural, Iron Grey, Luminous Pink, Pale Sienna, Powerful Orange, Spectacular Ultramarine, Slightly Greyed English Green, and Sunshine Yellow. Each one is crafted from high-tech ceramic, with a 39mm case and matching bezel and bracelet. Limited to just 99 sets, with each watch also available separately in a limited run of 999 examples.
