About Richard Mille

Herald at their intial release in 2001 as a break from the past and a new direction of horology, the wristwatches of Richard Mille were from their very inception, extraordinary and uncompromising.

Product Specifications

TECHNICAL SPECIFICATION OF THE RICHARD MILLE TOURBILLON RM 002-1

CALIBER RM 002-1: Manual winding tourbillon movement with hours, minutes, power reserve, torque indicator and function selector.

Dimensions: Length 45 mm x 38.30 mm (widest point) x 11.85 mm (thickest area)

MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)

POWER RESERVE:
70 hours

TORQUE INDICATOR
Shows the mainspring tension and enables the movement timing to be optimized. 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. (These indications appear on the numeric scale to the right of the winding barrel).

VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance gives better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time.

FAST ROTATING BARREL (6 hours per revolution instead of 7,5)
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 the start of winding. 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.

BALANCE SPRING
Invented by A.L. Breguet in the 18th, perfected and codified by Edouard Phillips in the 19th, the specially calculated shape of the Breguet/Phillips balance spring provides excellent chronometric results in tourbillon escapements.

ESCAPEMENT
New in-line escapement design, aimed at reducing friction.
CLOSURE OF THE BARREL COVER BY 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
The ribs ensure better rigidity for the bottom plate/bridge assembly.

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.

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.
