TECHNICAL TOUR DE FORCE

Continuing the expansion and application of truly unique materials to watchmaking, the RM 021 is the first watch created with a composite baseplate utilizing a titanium exterior framework in combination with honeycombed orthorhombic titanium alumide and carbon nanofiber.

Main characteristics

Richard Mille always dreamt of incorporating a titanium honeycomb structure, a concept traditionally used in aeronautics, and this choice gave a baseplate that was both rigid and very light. The objective was to juxtapose and laser-weld each tiny cell. This achievement on such a microscopic scale is a major technical tour de force in the world of 21st century horology.

CALIBER RM 021
Manual winding tourbillon movement with hours, minutes, power reserve, torque indicator and function selector.

FUNCTION SELECTOR In a manner similar to a car's gearbox, a push-button located at the center of the crown allows one to select the winding, neutral and hand setting functions with a simple push. A hand at 4 o’clock displays the selected function: W (Winding) – N (Neutral) – H (Hands).

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.

Manual winding tourbillon movement with hours, minutes, power reserve, torque indicator and function selector.

TORQUE INDICATOR Utilizing a numeric scale located between 12 and 1 o’clock, the indicator provides visualization of the mainspring’s internal tension, allowing optimization of the movement’s timing. Below 53 dNmm, the spring is too slack; at the other extreme, above 65 dNmm, excessive tension can adversely affect the running of the movement and may even cause damage.

MOVEMENT BASEPLATE OF TITANIUM & HONEYCOMBED ORTHORHOMBIC TITANIUM ALUMINIDE WITH CARBON NANOFIBRE CORE

Orthorhombic titanium aluminides are new group of alloys, developed from the main class of titanium aluminides, which possess a specific crystalline molecular structure ordered on the orthorhombic phase of Ti2AlNb. Its use within a honeycombed geometrical pattern was originally the subject of research by NASA for application as a core material of supersonic aircraft wings, where resistance to extremely high temperatures and torsion is paramount. The alloy in this honeycombed form has unparalleled stiffness, a low thermal expansion coefficient and exceptional torsion resistance.

MODULAR TIME SETTING MECHANISM FITTED AGAINST THE CASEBACK

Provides the following advantages for longevity and maintenance: - Since the component is mounted outside of the movement, the time setting assembly can be changed without affecting the integrity of the bottom plate in the event of a possible defect or during maintenance, - The mounting and dismantling of this module from the back will not require the removal of the hands and the dial.

FAST ROTATING BARREL


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.
