Designed for tennis star Rafael Nadal to wear when competing, this tourbillon features a lightweight case and movement, the latter held in suspension within the case by four braided steel cables. As a result the RM27-01 calibre manual winding tourbillon can withstand accelerations of over 5,000 g. The movement itself is made of titanium and LITAL®, an alloy of lithium, aluminium, copper, magnesium and zirconium, on a base plate in grade 5 titanium. LITAL® is used in Formula 1, as well as in aerospace, since the lithium provides greater flexibility and shock resistance. The case is made from an anthracite polymer that has been injected with carbon nanotubes, creating an extremely strong, yet lightweight housing. Instead of the usual sapphire, the crystal used for the dial is made of Grilamid TR-90—a polymer used in sports sunglasses because of its lightness, flexibility and high resistance.
