Richard Mille revisits the extraordinary movement of the legendary RM 012, reconciling innovations at the level of materials with a testament to horological architecture. Known as the RM 12-01 Tourbillon and available in four different 18-piece limited editions available exclusively at Richard Mille boutiques in the Americas, the construction of the case on the new RM 12-01 Tourbillon follows the tripartite principle in case combinations that all include Carbon TPT.
