RM 011 AUTOMATIC FLYBACK CHRONOGRAPH 511.06AN.91V-1
- Movement Type: Automatic Self-Wind
Richard Mille RM 011 511.06AN.91V-1
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.
TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE CALIBER RM 011 Felipe Massa Flyback Chronograph
CALIBER RM011-S: skeletonized automatic winding movement with adjustable rotor geometry offering hours, minutes, seconds, chronograph, 60-minute countdown timer, 12-hour totalizer, oversize date, month.
Dimensions: length 50 mm x 40 mm (widest point) x 16.15 mm (thickest area).
MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
POWER RESERVE
• Circa 50 hours without chronograph running.
• Actual power reserve results will depend on the period of time the chronograph is utilized.
BASEPLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM
The manufacture of these components in grade 2 titanium with black PVD coating allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train.
FLYBACK CHRONOGRAPH
By using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism. This was originally developed for pilots, in order not to lose time (and therefore accuracy) from stopping, resetting and starting the chronograph whilst traversing a navigational point.
Running operation: The user can start or stop the chronograph function via the pusher located between 1 and 2 o’clock. The Flyback Function can be continuously reset at will by depressing the second pusher located between 4 and 5 o’clock.
Stopping: Use the start/stop pusher between 1 and 2 o’clock to stop the chronograph, then depress the reset/flyback pusher once.
ANNUAL CALENDAR
Automatic adjustment for months of 30 or 31 days.
OVERSIZE DATE DISPLAY
Semi-instantaneous, placed in a red outlined horizontal aperture under 12 o’clock.
MONTH DISPLAY
Semi-instantaneous indicate with Arabic numerals, placed between 4 and 5 o’clock.
ROTOR WITH VARIABLE GEOMETRY
• Arm in grade 2 titanium
• Flange in grade 2 titanium
• 6-positional adjustment via grade 5 titanium screws
• Wings in 18-carat, high palladium content white gold
• Weight segment in tungsten/cobalt alloy
• Ceramic ball bearings
• Unidirectional; anti-clockwise winding direction
This exclusive RICHARD MILLE design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level whether it be sporting or non-sporting environments. By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or slow it down when sporting activities are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized and personalized to the owner’s lifestyle.
DOUBLE BARREL SYSTEM
The double barrel system helps to improve the torque stability over a longer period. This is achieved by using more rotationnal turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.
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.

WATCHCASE
This was the subject of an entire year of research and development. With regard to the production of each case, 68 different stamping operations are required for the three main components (bezel, middle section and case back). The machine tooling process requires 8 days of adjusting the machines for the bezel, 5 days for the middle section and 5 days for the case back. Prior to this process, developing a methodology for carrying out this series of operations took 120 hours, the drawings for the tools 130 hours, and implemention 180 hours. Each rough case involves 202 separate machining operations. The design and execution of the watch demonstrates a complete conceptual approach to the movement, case and dial. As a result, everything has been constructed according to an extremely rigorous specification, in the manner of the analytical engineering methods used in the design of Formula 1 racing cars where the chassis and the engine are developed in complete harmony. 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. Features such as these are evidence of uncompromising workmanship. The tripartite case is water resistant to 50 meters, ensured by three Nitril O-ring seals. The case is assembled with 16 spline screws in grade 5 titanium and abrasion resistant washers in copper-nickel-zinc alloy.
