Manufacturer Description

TECHNICAL SPECIFICATIONS OF THE EXTRA FLAT TOURBILLON RICHARD MILLE RM 017

Rectangular case - available in titanium, 18k white gold or red gold, and gem-set case.

CALIBER RM017: manual winding, extra flat tourbillon movement with hours, minutes, power reserve and function indicator.

Dimensions: 49.80 mm x 38.00 mm x 8.70 mm

MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)

POWER RESERVE
Circa 70 hours, located on a scale at 2 o’clock.

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).

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

TORQUE LIMITING CROWN IN TITANIUM
This additional security system prevents from accidental overwinding, which could cause damage such as the winding stem breaking or too much pressure on the barrel spring.

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 is also helpful in the distribution of the mainspring’s internal tension.

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.

SAFETY SYSTEM WITH BLOCKING GEAR
This system protects the roller jewel of the balance as well as the winding barrel from possible overwinding.

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.

TITANIUM BASEPLATE
These components are manufactured in grade 5 titanium and treated with a black PVD coating. As a consequence the whole assembly is extremely rigid, with precise surface flatness, an essential for the perfect functioning of the geartrain.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
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.

CASE
The RM 017 portrays the current collection’s themes of motor sport and sailing, reflected in sleek, discreet lines that are among the thinnest of the collection, it represents a new, visual transformation suitable for all occasions with the same wrist fitting curvature and taper typical of all Richard Mille creations. The case represents an uncompromising approach, with extensive attention to all details of the case design with numerous stamping and machining operations required for the three main components(front bezel, back bezel and caseband). More than 18 days of machine adjustment are required and more than 400 hours of technical research and drawing even before production can begin. Each case requires 202 separate machining operations. The case of the RM 017 requires 39 swaging operations including 16 striking, 270 milling operations. The machining lasts 4 hours and 15 minutes. Concerning the finishing work, 1 day is needed for grinding, glazing and polishing. The design and execution of this watchcase typifies the complete holistic approach to all parts of the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications. For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws. The tripartite case is water resistant to 30 meters, ensured by two Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE 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.

INTERIOR FLANGE
In carbon fiber, with index points filled with approved luminous material.

DIAL
In sapphire (thickness: 0.30 mm) with anti-glare treatment (both sides), protected by 8 silicon braces inserted in the upper and lower grooves.

CRYSTAL
• Bezel side: In sapphire (1800 Vickers) with anti-glare treatment (both sides).
• Thickness: 1.15 mm
• Case back: In sapphire with anti-glare treatment (both sides).
• Thickness: at the center 1.05 mm and outer edges 1.39 mm

FINISHING

MOVEMENT
• Anglage and polishing by hand
• Locking sections hand polished
• Sapphire blasted milled sections
• Lapped and polished contact points
• Burnished pivots

STEEL PARTS
• Sapphire blasted surfaces
• Anglage and polishing by hand
• Burnished sections
• Satin finished surfaces

GEAR WHEELS
• Concave chamfering with a diamond tool
• Circular finished faces
• Rhodium-plating (before cutting the teeth)
• Minimum correction applied to the wheels in order to preserve geometry and performance
