The All-New RM 88 Automatic Tourbillon Smiley by Richard Mille – Playful and Colourful

The new RM 88 Automatic Tourbillon Smiley by Richard Mille is a playful and colourful creation with attention to detail and perfection taken to the utmost, breathing life into a veritable smile mechanism.

THE SMILE, A UNIVERSAL LANGUAGE

A yellow circle, two oval eyes, a wide upturned mouth … The Smiley, drawn by Franklin Loufrani just over 50 years ago, has become an established symbol in the collective consciousness. It serves as the embodiment of positivity, joy and sharing and has played a major role at the heart of pop culture across several creative generations. This leading role was enough for the teams at Richard Mille to launch into the creation of an emotion-driven watch emphasising all these values.

THE MECHANICS OF A SMILE

Around the Smiley’s radiant face, an array of miniature sculptures takes possession of the RM 88 Automatic Tourbillon Smiley’s movement, forming and reforming a surreal scene, brimming with fun and enthusiasm and demonstrating true mastery of the infinitely small. Light as it may seem, the creation of this ballet was a technical challenge of the highest order. But the dream has now become reality, with attention to detail and perfection taken to the utmost, breathing life into a veritable smile mechanism.

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

Microblasted grade 5 titanium with PVD treatment lends great rigidity to the baseplate and the bridges, as well as the precise surface flatness, essential for perfect functioning of the gear train.
Grade 5 titanium is a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to func¬tion effortlessly.
The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automotive industries.

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

CASE IN ATZ WHITE CERAMIC AND RED GOLD

Such splendour of colour and scenography, both front and back, deserved a setting that would do justice to the composition.

The design and execution of the watch demonstrate a holistic approach to conception of the movement and the case. As a result, everything has been constructed according to extremely rigorous specifications. For example, a casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by titanium screws.

The bezel and caseback are in ATZ white ceramic. This is made from tubes of aluminium oxide powder injected at a pressure of nearly 2,000 bars. This high-pressure injection increases rigidity by 20 to 30% and reduces the material’s porosity to an absolute minimum. ATZ is known for its high scratch resistance (1,400 Vickers) and unchanging colour. Next to diamond, it is one of the hardest materials in the world. Long and difficult machining using diamond tools is required to create a perfect example of this complex, curved bezels and satin finish.

The caseband is made of 18K 5N red gold.

The tripartite case is water resistant to 50 metres, ensured by 2 Nitrile O-ring seals. The case is assembled with 12 grade 5 titanium spline screws and abrasion-resistant washers in 316 L stainless steel.
