TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE
RM 022 “AERODYNE” DUAL TIME ZONE
As for the RM 021, the new RM 022 communicates space and supersonic speed that inspire the brand
since 2001. However this Tourbillon has another attribute in that it is the first watch to combine a dual
time zone with an external structure in titanium combined with orthorhombic titanium aluminides and
carbon nanofibres.
CALIBER RM 022: manual winding tourbillon movement with hours, minutes, dual time zone,
power reserve, torque indicator and function selector.
Dimensions: length 48 mm x 39.70 mm (widest point) x 13.85 mm (thickest area).
MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
MOVEMENT BASEPLATE OF TITANIUM & HONEYCOMBED ORTHORHOMBIC TITANIUM
ALUMINIDE WITH CARBON NANOFIBER 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 on 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.
POWER RESERVE
Circa 70 hours, indicated on the power reserve barrel located between 11 and 12 o’clock.
TORQUE INDICATOR
Utilising a numeric scale located between 12 and 1 o’clock, the indicator provides visualisation of the
mainspring’s internal tension, allowing optimisation 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.
DUAL TIME ZONE INDICATOR
Indicates a dual time zone with hours on a transparent sapphire crystal disc. These come into
view when suspended above the light colored field located near 3 o’clock. The dual time zone is
simple to adjust via a pusher located at 9 o’clock.
VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balancer gives better reliability in the event of shocks, movement assembly and
disassembly, and also guarantees better chronometric results over an extended period of time.

RM 022 “AERODYNE”
FAST ROTATING BARREL (6 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.
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during start-up.
It also aids in the even distribution of the mainspring’s internal tension.
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).
MODULAR TIME SETTING MECHANISM FITTED AGAINST THE CASE BACK
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.
WHEEL BASED TIME SETTING SYSTEM (back of the movement)
Provides smooth time setting functions through the elimination of engaging friction by replacing
it with rolling friction.
BARREL COVER CLOSURE THROUGH EXCENTRIC SCREWS
This development is part of a coherent and logical philosophy regarding longevity and the mechanical
maintenance of ultra-high quality wristwatches and machines.
CERAMIC ENDSTONE FOR THE TOURBILLON CAGE
This reflects a technical and long-term view towards the elimination of wear phenomena, resulting in
improved technical tribology.
CENTRAL BRIDGE IN RIGIDIFIED ARCAP
Ensures high rigidity of the bottom plate and the bridge assembly of the going train.
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.

RM 022 “AERODYNE”
WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The central involute profile of the winding barrel teeth and pinion provides an optimal pressure
angle of 20°. This promotes effective rotary motion and allows for compensation of possible
variations in the engagement of the going train, thus insuring excellent torque transmission with
a distinct improvement in performance.
