The result of a collaboration that started four years ago culminated yesterday as Richard Mille himself presented the watch designed in collaboration with Sylvester Stallone at a casual lunch in Los Angeles, California. Priced at almost one million USD the new RM 25-01 Tourbillon Adventure is available in a limited edition of 20 pieces and exclusively sold at Richard Mille boutiques worldwide. In the words of Richard Mille himself: "The RM 25-01 is like no watch that has ever existed before. Like Sylvester Stallone himself, it is completely unfettered.
