The RM 27-04 balances a lightweight design–at 30 grams including the strap–with tremendous resistance. Its tourbillon calibre, which is suspended within the case, can resist accelerations of more than 12,000 g’s, a record for Richard Mille. The movement is entirely supported by a micro-blasted mesh just 855 square millimetres in surface, comprised of a single cable in braided steel measuring 0.27mm in diameter, and held in place by two tensioners in PVD-treated 5N gold. This construction is unprecedented in the world of watchmaking. It is unique in more ways than one, as it also marks the 10th anniversary of the partnership between Rafael Nadal and Richard Mille. This watch is a limited edition of 50 pieces.
