Part of a series of new horological advances realized by Richard Mille was the successful creation of a carbon nanofiber movement baseplate, the first in watchmaking history. This new material was first tested with great success in the RM 006, an experimental model. The technical results were remarkable and Richard Mille therefore decided to expand the use of carbon nanofiber further throughout his tourbillon range.
Progress in this important area of horological research begun by Richard Mille has now opened up a new era of applying new materials in the watchmaking industry. The RM 020 furthers this development by being the first pocket watch ever built using a baseplate structure of carbon nanofiber. The RM 020 is supplied together with a special type of titanium watch chain comprising a new design of fast release/attach mechanism.
In the tradition of fine pocket watches of the past, the RM 020 can also be used as a pendulette de bureau with a specially designed stand in complementary style.
POWER RESERVE Circa 10 days, supplied by two directly engaged winding barrels, visible via a numeric sale located between 9 and 10 o’clock.
CASE Central caseband in titanium (all versions), with both front and back bezels in either 18ct red gold, white gold or titanium.
FUNCTION INDICATOR In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand setting positions as the crown is pulled out. Each position is indicated via a hand at 4 o’clock displaying the following functions: W(Winding) – N(Neutral) – H(Hands).
CALIBER RM 020 Manual winding tourbillon movement with hours, minutes, power reserve and function indicator.
CARBON NANOFIBER BASEPLATE
This is an isotropic composite material created from carbon nanofibers molded under a high pressure of 7,500 N/cm2 and a temperature of 2,000 ̊C, resulting in a material with high mechanical, physical and chemical stability in all directions. The ribbed perimeter of the movement plate assures the highest rigidity between the plate and bridges. Carbon nanofiber composite structures such as this are amorphous, chemically neutral and dimensionally constant within a very wide range of operating temperatures, including those outside of normal ranges. This stability assures the highest integrity of the movement’s going train under all conditions.
VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance with overcoil spring (originally designed for pocket watches in particular), gives better reliability in the event of shocks, movement assembly and disassembly, and also guarantees excellent chronometric results over an extended period of time.
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding. It also aids in the even distribution of the mainspring’s internal tension.
WHEEL BASED TIME SETTING SYSTEM
Provides smooth time setting functions through the elimination of engaging friction by replacing it with rolling friction.
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.
