This is the new Richard Mille RM056. It is a split-seconds chronograph with tourbillon with a case built entirely out of sapphire. The whole thing. In fact, this three piece case is actually milled from one solid block of sapphire, cut to allow for the movement placement and then reassembled as this watch. Sapphire is indeed highly scratch-resistant, though somewhat brittle, so in theory, this watch could break if dropped. Still, it features just an absolutely breathtaking movement. The lightest split-chrono tourbillon movement in the world and an incredible look. Only five RM56’s will be made. The cost? A roughly £1.1 million GBP
