The first, or ‘peripheral’ baseplate, is fixed to the case and supports the tensioner mechanisms. The second, known as the ‘central’ baseplate, is linked to the peripheral baseplate by cables and incorporates the wheels comprising the calibre as well as the winding mechanism. The central baseplate rests, like a spider in the middle of its web, on two braided steel cables just 0.27mm in diameter. These cables, sketching a three-dimensional structure in their path through 10 pulleys, are anchored by four tensioners. The watchmaker is responsible for tensioning the cables by rotating a spline screw located at the centre of each tensioner. By ensuring an even distribution of tension, this pulley system guarantees perfect balance of the whole mechanism. The suspended movement and the use of grade 5 titanium (double baseplate and bridges) contribute increased stiffness, while ensuring smooth functioning of the going train and optimal shock protection. The RM 53-01 Tourbillon case is machined in Carbon TPT®, an immensely durable and protective material that would hold up in a polo match. However, traditional sapphire watch glass was not going to be viable. One straight smash with a polo mallet would be sufficient to break the standard glass. Accordingly, Richard Mille’s engineers collaborated with Stettler—a world- renowned sapphire specialist—and took inspiration from current practices in the automotive realm to produce a laminated glass. Use of this glass, composed of two sheets of sapphire glass separated by a thin Polyvinyl film, constitutes a horological first. In the face of the strong shockwave produced by a blow from a mallet, the glass will crack, but without ever shattering. With anti-reflective and UV coatings, this glass, which preserves the movement from the external environment, is patented exclusively to Richard Mille. The RM 53- 01 Tourbillon Pablo Mac Donough is a limited edition of 30 pieces in Carbon TPT®.
