Richard Mille Rm 47 Manual Winding Tourbillon

THE TIME OF THE SAMURAI

The RM 47 Tourbillon harks back to the sources of Japanese crafting tradition in proposing an allegory of Bushido, the samurai code of ethics whose values still prevail in Japanese society.

It is not without reason that the samurai armour at the heart of the RM 47 Tourbillon sports the crest of the Asano clan.

A work of art of impressive realism, the RM 47 Tourbillon incorporates an extremely compact calibre, specially designed to make room for the samurai suit. The boldness of its volumes gives this decoration such a presence that it gives the impression of sculpture almost as much as of engraving.



Associating art and spirituality. Creating a new masterpiece designed as an aesthetic tribute to Japanese culture. The RM 47 Tourbillon is the fruit of intense reflection and nearly four years of design work. The model was born of a friendly conversation between Richard Mille and the twice Formula 1 world champion and brand partner Fernando Alonso, a passionate enthusiast of Japanese traditional arts and the Samurai principles.

BASEPLATE AND BRIDGES IN GRADE 5 TITANIUM

The baseplate and the bridges are crafted in grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, ensuring that the gear train functions smoothly.



The alloy is 90% titanium, 6% aluminium and 4% vanadium. This combination enhances the alloy’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automotive industries.

The use of microblasted grade 5 titanium in combination with a grey PVD treatment confers great rigidity on the entire assembly and provides rigorously even surfaces.



The skeletonised baseplate and the bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.

SAMURAI ARMOUR IN 3N YELLOW GOLD

Protecting the RM47 calibre, the samurai armour created from 3N yellow gold has been entirely hand-engraved by Pierre-Alain Lozeron.



It was essential for the work to provide volume, sculpting in trompe-l’œil to give the required depth to the effigy of the samurai equipped with his two swords. There is a wealth of details, such as the helmet ribbon, the sword’s attachments, the crest representing two crossed falcon feathers positioned on the tourbillon, and the expression of the mask, which had to convey the samurai’s warrior spirit. In total, it takes no less than 16 hours of engraving to obtain the 11 components that make up the Samurai.
