Richard Mille wanted to set the world record for the lightest watch in the world, he did it when making this special piece, The RM027-01, Weighing a exactly 18.83 grams ( excluding the strap ) The RM027-01 is made from an extremely strong anthracite polymer injected with carbon nanotubes.This combination produces a material that protects the movement and the tourbillon positioned inside it against impacts.
The caseband and caseback comprising a single unit ensures improved lightness and rigidity. The crystal, with its anti-reflective treatment, has remarkable properties that ensure extreme toughness and optimum rigidity.
The baseplate of the RM 27-01 Rafael Nadal is attached to the case by 4 braided steel cables, each with a diameter of just 0.35 mm. These cables are held taut by an ingenious mechanism of tensioners (located at 3 and 9 o’clock) and pulleys, which act like pylons positioned at the four corners of the movement. Each cable is fixed to the tensioner, and passes over the upper pulley and into the movement, before returning via the lower pulley to finish in the lower flange. Once the watchmaker has threaded the cables, he tensions them by rotating the central tensioner ring using a special tool. Designed to stay in suspension inside its case, the calibre RM27-01 can withstand accelerations of over 5,000 g.
The movement of the RM 27-01 is made of titanium and Lital®, a lithium alloy containing aluminium, copper, magnesium and zirconium, with a density of 2.55. The addition of Lithium provides to the mechanism more flexibility and greater shock resistance.This alloy is also applied in aerospace on the Airbus A380, helicopters, rockets, satellites as well as in Formula 1.Power reserve

The calibre RM27-01, developed in 2013, with its complex, original architecture is the result of Richard Mille’s determination to create a movement held in total suspension in the heart of its case.
Inspired by civil engineering infrastructure suspensions, Richard Mille wanted to adapt these modes of construction to the watchmaking sphere, shrinking them to a space just a few tens of millimetres wide.
