RM 021 Tourbillon "Aérodyne" by RICHARD MILLE
Richard Mille won control of its reputation as a pioneer, eight years ago, with its two watches RM 001 and RM 002. Unanimously acclaimed by the press and the public, those achievements have pushed the limits of the watch industry, both in design and mechanical inventiveness that the materials used. However, it was only the beginnings of a revolution coming. Indeed, beyond their surprising originality, these two watches opened the way for a new approach to watchmaking that would energize and change the essence of this ancient art. Indeed, models RM 001 and RM 002 have undoubtedly demonstrated that innovative and sophisticated technology can integrate perfectly with the values of rarity, exceptional characteristics and tradition of high watchmaking.
Today, eight years after this turning point for watches, watch, RM 021, which occupies a prominent place immediately at the heart of watchmaking, made its entry in the collection. The very name of this watch is not a mere coincidence, it is the 21st century and reflects the continuity of innovative RM 001 and RM 002. This unique piece also expresses the concepts of air, space and speed supersonic behind the brand since its inception in 2001.
RM 021, another example of development and application of materials unique to watchmaking, is the first watch created from an external structure associated with titanium in the titanium aluminide orthorhombic alveolate and the carbon nanofibers . The orthorhombic titanium aluminide is an alloy that has a unique molecular structure classified in specific crystalline phase of orthorhombic Ti2AlNb. Used in a geometric motif Honeycomb shaped honeycomb, this material is used by NASA in the manufacture of wings for supersonic aircraft which the thermal and mechanical properties are paramount. In a honeycomb structure, the alloy has an unmatched rigidity, low thermal expansion and exceptional resistance to twisting. The shape of the platinum, as it appears from the face, is characterized by the V-profile wing of an airplane in flight when their ends are higher than the fuselage. The cylinder and the vorticity are both placed in the central creusure aerodynamic structure, maintained in equilibrium on bridges light and air with four arms of both sides.
The RM021 is available in titanium and red gold or 18 carat white, with an alligator strap with the buckle.

Key Features
(Many of them are major technical innovations)
Platinum & Titanium aluminide orthorhombic titanium honeycomb core with carbon nanofibers
The orthorhombic titanium aluminide is a new type of alloy, a derivative of Titanium Aluminides currents, which have a specific crystalline molecular structure placed in the orthorhombic phase of Ti2AlNb. Its use in a geometric motif Honeycomb shaped honeycomb was originally studied by NASA that uses it as an essential material in the manufacture of wings for supersonic aircraft which the thermal and mechanical properties are essential . In a honeycomb structure, the alloy presents an incomparable rigidity, low thermal expansion and exceptional resistance to twisting.
Reserve walk
About 70 hours, displayed on the indicator of power reserve between 11 and 12 hours.
Torque Indicator
A numerical scale between 12 hours and 1 hour is the spring tension and allows the engine to optimize the functioning of the movement. Below DNMM 53, the spring is too relaxed and, unlike over 65 DNMM, excessive voltage may damage the operation of the mechanism or damage.
Variable inertia balance
The variable inertia balance ensures greater reliability in case of shock and during assembly and disassembly of the movement. The accuracy is enhanced over the long term.
Cylinder rotation speed (a trip in 6 hours instead of 7.5)
This type of barrel has the following advantages:
The recurrent phenomenon of internal friction within the engine is significantly reduced, which improves performance;
The spring-engine has an excellent curve delta, with a power reserve to ideal ratio between performance and consistency.
Ratchet barrel progressive decline in
This device provides a significant gain (about 20%) in the winding, especially when the spring is not armed. It also contributes to proper distribution of the internal tension of the spring motor.
Mode Selector
A push in the center of the crown can select with a single winding, setting the time or the neutral position, as on the selector gearshift of a car. A needle at 4 o'clock displays the selected mode: W (winding, winding) - N (Neutral) - H (hands, setting the time of needles).
Module update time mounted on the bottom of the case
It has the following advantages in terms of longevity and maintenance
This module is mounted outside the movement, it can be replaced without touching the plate during an operation and maintenance;
The assembly or disassembly of the module from the bottom does not require the removal of needles and the dial.
Improved system of setting the time (back of movement)
The friction engagement is replaced by rolling friction, the operation of setting the time is more fluid.
Barrel lid sealed with eccentric screw
This feature stems from the desire to follow a logic of durability and ease of maintenance, consistent with the extremely high quality of the mechanical design.
Against pivotal ceramic cage tourbillon
This feature stems from the desire to reduce the wear and long term is a technical answer to tribological phenomena.
Bridge center arcap rigidified
It ensures perfect rigidity of the assembly of the deck and the deck.
Vis fluted titanium grade 5 for bridges and box
By their shape, these screws offer better control of torque during assembly. As a result, they resist perfectly operations for mounting or dismounting and are not subject to aging.
Involute profile for the central teeth of the cylinder and the pinion small average
The central involute profile of the teeth exerts pressure on a optimal angle of 20 °, which improves the efficiency of the cycle and compensates any changes in commitment. The result is an excellent transmission of torque and a significant improvement in performance.
