very reflection emanating from the new RM 07-01 Coloured Ceramics awakens the memory, brilliantly sealing the creativity of an object that has become truly symbolic. The dials radiate, textures come to life, and colours vibrate as the world undergoes a metamorphosis: the shades compose a dreamlike universe where technical mastery diffracts the ordinary. The diamond, placed upon the material like an eternal snowflake, immortalises this moment.

The inspiration draws from the creative energy of the 1980s—an era of emancipation, bold contrasts, and unexpected materials. Richard Mille embraces this heritage, revisiting it through dials rich in multiple decorative techniques. As Cécile Guenat, Creative and Development Director, noted during the creation of the two previous collections: ‘These watches play on the juxtaposition of vibrant colours and contrasting textures, asserting a singular and disruptive graphic identity.’

The grey PVD-treated red gold dial combines coloured ceramics details finished to the nearest micron, laser-cut rubber appliqués, and diamond-set components meticulously housed within white gold inserts. To this interplay of materials and textures—where structured geometry and expressive abstraction heighten one another—is added guillochage. ‘This secular decorative technique reaffirms our commitment to making no compromises on either aesthetic or technical grounds,’ emphasises Cécile Guenat.

Consisting of a multitude of lines traced using a manual rose engine, the guilloché pattern is composed of fine, striated curves playing with effects of light and shadow. Each motif demands absolute precision from the guillocheur: a constant, repeated, and millimetric pressure to ensure the same amount of material is removed from every gold piece.

These dials are built upon the in-house automatic CRMA2 calibre. Skeletonised and crafted from grade 5 titanium, the movement offers a power reserve of 50 hours, stored within a fast-rotating barrel. This energy is generated by a variable-geometry rotor in gold, whose contrasts—highlighted by the electroplasma treatments of the baseplate and bridges—accentuate the movement’s visual power. The skeletonised architecture fully reveals this true laboratory of emotions.

The collection is available in three ceramic colours: blush pink, lavender pink, and powder blue. While chosen for its aesthetic qualities, TZP (Tetragonal Zirconia Polycrystal) ceramic also meets rigorous performance standards. Its stability, chromatic intensity, and resilience ensure that its brilliance remains undiminished over time.

The gem-setting of these bezels represents one of the collection’s highlights—a particularly complex undertaking given the extreme hardness of the material. The aesthetic sign of the mitraillage requires absolute precision, while the gold prongs and stones, delicately inserted by hand, perpetuate the exceptional savoir-faire unique to Richard Mille.

The polished white gold casebands, featuring satin-finished pillars, are also illuminated by a variety of stones. The RM 07-01 Blush Pink combines diamonds with yellow and blue sapphires, while the RM 07-01 Powder Blue pairs diamonds with pink sapphires and tsavorites. Meanwhile, the RM 07-01 Lavender Pink reveals a vibrant interplay of diamonds, orange sapphires, and rubies. Beyond the aesthetic statement alone, the rigorous technical standards and contemporary vision deeply respectful of watchmaking traditions, evident in these mastered harmonies, celebrate an undeniable creative audacity.

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

• Microblasted grade 5 titanium with electroplasma treatment gives great rigidity to the baseplate, as well as precise surface flatness which is essential for the perfect functioning of the gear train. Bridges are also in grade 5 titanium, microblasted and electroplasma treated. The skeletonised baseplate and the bridges were subjected to separate and extensive validation tests to ensure optimal strength requirements.

FREE-SPRUNG BALANCE WITH VARIABLE INERTIA

• This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks and also during movement assembly and disassembly, hence better chronometric results over time. The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 small adjustable weights located directly on the balance.

FAST-ROTATING BARREL (5 HOURS PER REVOLUTION INSTEAD OF 7.5 HOURS)

• This type of barrel provides the following advantages: • The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance, • Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.

VARIABLE-GEOMETRY ROTOR

• The RM 07-01 uses variable geometry to optimize the rotor’s winding motion. Rotor specifications: • Heavy external outside edge and heavy edge ring in 5N red gold • Weight segment in heavy metal • Ceramic ball bearings • Automatic winding system OneWay® with ball bearings • Bidirectional winding system

This rotor with variable inertia has been incorporated into the CRMA2 calibre as it allows the rotor to be set according to the owner’s activity level. The setting is modified by adjusting the 2 weights which can be moved into the correct position and fixed in place by spline screws.

GEAR TEETH PROFILE

• The entire going train of the watch, the primary transmitter of power throughout the movement, utilises a pressure angle of 20 ̊ for the teeth of the wheel. This system equalises any discrepancies that might arise between the centre of each wheel, for instance during thermal changes and normal use, and promotes an excellent transmission of torque to the balance wheel, thus supporting excellent chronometric characteristics.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE

• This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

Three coloured ceramics are used for these RM 07-01 bezels: Blush pink TZP ceramic, lavender pink TZP ceramic and powder blue TZP ceramic.

TZP (Tetragonal Zirconia Polycrystal) is a biocompatible ceramic constituted of over 95% zirconia (ZrO2).

Its properties include remarkable corrosion resistance, a hardness providing scratch resistance (1,400 Vickers) and toughness superior to that of sapphire, associated with a desirably low density of around 6 g/cm3.

The submicron grain size furthermore permits excellent surface finish for a stunning matt effect.

A long and difficult machining and grinding process using diamond tools is necessary to create the complex forms of the bezels. The casebands are made of microblasted white gold with hand-polished pillars.

The three-part 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 316L stainless steel.
