Richard Mille is a Swiss watch manufacturer founded in 2001 by Richard Mille and Dominique Guenat, produced at Les Breuleux in the Jura. It is defined by the curved tonneau case, skeletonised baseplates, and materials borrowed from motorsport and aerospace - Carbon TPT, Quartz TPT, titanium and sapphire. Annual production is roughly 5,000 watches, which is why Richard Mille commands some of the highest prices and secondary-market premiums in Swiss watchmaking.
