RM 52-05: Manual Winding Tourbillon Pharrell Williams by Richard Mille

Mankind has looked at Space from the Earth for time immemorial. But with the RM 52-05 Tourbillon Pharrell Williams, the Earth is observed from Mars, a viewpoint expressing one of Pharrell Williams’ dreams. Share

Maybe the word that best sums up Pharrell Williams is ‘universal’ —in every sense of the term. A deep link to the cosmos is something he felt very early on. No surprise, then, that Pharrell grew up a major fan of Star Trek, as anyone will know who has seen him use a Vulcan salute when conveying the name of his label, Star Trak. He has never made any secret of his fascination for the cosmos, or of the deep sense of spirituality he derives from it, of the wholeness at the centre of things.

Conjuring the visions, fantasies, and other imaginary projections of the brand’s partners is a familiar quest for Richard Mille, one that begins all over with every new adventure. A truly artistic project, the development of the RM 52-05 is special for the way it hinges on interpreting an idea, a symbol and a desire. This last has taken the form of a tourbillon whose originality lies in its astonishingly multidisciplinary techniques.

The grade 5 titanium helmet resting on a structure depicting the upper part of a spacesuit, also in grade 5 titanium, connects the dial to the movement beneath it. It has been painted white using an airbrush that was initially developed for street artist Cyril Kongo, who hand-painted the RM 68-01.

The projectors and cameras, represented by two diamonds and a black sapphire set on either side of the helmet, required particular care and attention. The stones are showcased by a moderate gem-setting depth, reflectors that have been polished and bevelled using watchmaking techniques and the alignment of their tables, all of which are facing the same way to ensure a uniform reflection.

To recreate the imaginary Martian scene, the curved 5N gold visor has been engraved using specially created burins, grand-feu-enamelled and then hand-painted. The engraving alone requires 15 hours per piece, followed by an entire day of grand feu enamelling. Pierre-Alain Lozeron had to apply all his patience, skill and dexterity to bring these creations to life.

The brown Cermet combines the lightness of titanium with the hardness of a ceramic. It consists of a metallic zirconium matrix associated with high-performance ceramic that gives the material its incredible brown hue with metallic reflections.

Cermet has a mass to volume ratio of 5.7 g/cm3 and a hardness of 1,200 Vickers, comparable to a traditional ceramic and making it eminently suitable for use in bezels and case backs, both areas that are highly vulnerable to scratches, while ensuring that the entire assembly is light in weight. These two elements are affixed to a caseband made of Carbon TPT®, which also contributes to lowering the total weight.

This high-tech material is made up of 600 layers of parallel filaments obtained by separating out carbon fibres. The layers, no more than 30 microns thick, are impregnated with a black resin. They are then assembled on a dedicated machine, which stacks the layers, varying the orientation of the fibres by 45° between layers. The composite is then heated to 120°C at a pressure of 6 bars in a kiln similar to those used for the production of aeronautics parts, after which it is ready to be machined at Richard Mille.

The tripartite case is water-resistant to 50 metres, ensured by 2 Nitrile O-ring seals, and is assembled using 24 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel. Richard Mille will produce 30 pieces exclusively available in the brand’s boutiques worldwide.
