RICHARD MILLE RM 27-01 TOURBILLON RAFAEL NADAL
Made of titanium and a lithium alloy, this watch may be super-light but the tennis player, one of the very few who wears a watch while playing, managed to ruin five of them while doing so. A new development was required to allow it to handle constant high vibrations. The solution? To suspend the entire movement on four 0.35mm thick braided steel cables, allowing it to withstand accelerations of more than 5000G.
