Like the RM 006, RM 008 and RM 012 tourbillons, the RM 27-02 belongs to the elite circle of Richard Mille watches destined to leave their mark on an era.
The RM 27-02 is an uncompromising calibre that reinterprets the art and methods of watch design in the 21^st century.

Following research by Richard Mille’s engineers into Carbon TPT® , the brand unveiled the very first skeletonised baseplate known as ‘unibody’, in which the caseband and baseplate have been fused into a single piece, removing the need to attach the two components together. This structure, inspired by the chassis of racing cars, enhances rigidity and resistance to impacts when used in watchmaking.

A major watchmaking and technological breakthrough machined at ProArt, the unibody baseplate is a technical feat that requires in-depth knowledge and mastery of micro-machining new materials -a concept that Richard Mille has nurtured since the very beginning.

The sculptural baseplate supports the bridges in grade 5 titanium, which are highly original in terms of their three-dimensional construction, their finishes (beveled, shot-blasted and satin-brushed by hand) and the complexity of their titanium and carbon composition. These bridges support an impressive mechanical heart capable of running for over 70 hours without detriment to its regularity thanks to a rapidly rotating barrel that delivers constant power from the beginning to the end of operation.

Such innovations are not limited to the heart of the watch, as demonstrated by the categorical absence of compromise on the case. Dressed in black and white, it inevitably catches the eye with its unique appearance. Working with North Thin Ply Technology, Richard Mille’s engineers have developed a highly original material known as Quartz TPT®, composed of hundreds of layers of quartz filaments piled on top of each other. These fibers are exceptionally resistant to high temperatures and are characterized by extreme strength and transparency to electromagnetic waves.

No thicker than 45 microns, the silica layers are inserted between layers of Carbon NTPT® by an automatic positioning system that changes the orientation of the fibers between each layer by 45°. Heated to 120°C in an autoclave similar to those used to make aeronautical components, the material is then ready for machining at ProArt. During this phase, the various layers of Quartz TPT® and Carbon TPT® are revealed at random, ensuring that each machined component is as unique as the heart of the baseplate, which is machined using the same process.

The bezel and solid case back in Carbon and Quartz TPT® are then attached to the unibody baseplate using 12 spline screws in grade 5 titanium. A sapphire crystal with anti-glare treatment adds the final finishing touch to this unique combination.
