RM 005 AUTOMATIC 504.04.91
- Movement Type: Automatic Self-Wind
Richard Mille RM 005 AUTOMATIC Watch 504.04.91: This rose pink gold watch features automatic movement with unigue patented rotor system containing 18-carat gold ball bearings. Functions include hours, minutes and date. Also available in rose gold, white gold and titanium.
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 SPECIFICATION OF THE RICHARD MILLE AUTOMATIC RM 005-1
CALIBER RM 005-1: Automatic winding movement with hours, minutes and date, with adjustable rotor geometry.
Dimensions: Length 45 mm x 37.80 (widest point) x 11.45 mm (thickest area)
MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
ROTOR WITH VARIABLE GEOMETRY
• Arm in grade 2 titanium
• Flange in grade 2 titanium
• 6-positional adjustment via grade 5 titanium screws
• Ribs 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.
POWER RESERVE: 55 hours
WATCHCASE
This was the subject of an entire year of research and development. With regard to the production of each case, 68 stamping operations are necessary 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 data processing 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 100 meters, ensured by three Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in copper-nickel-zinc alloy.
BOTTOM PLATE, 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.
DOUBLE BARREL SYSTEM
The double barrel system helps to improve the stability of torque over a longer period. This is achieved by using more turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.
DATE DISPLAY
Semi-instantaneous, placed in a vertical aperture at 7 o’clock. The calendar disc of sapphire crystal is treated with non-reflective coating on both sides.
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.
INTERIOR FLANGE (upper and lower)
In carbon fiber, with index points filled with approved luminous material.
CROWN
In grade 5 micro-blasted titanium, with double seal O-ring and collar in Alcryn.
DIAL
In sapphire (thickness: 0.40 mm) with anti-glare treatment (2 sides), protected by 8 silicon braces inserted in the upper and lower grooves.
