CALIBER RM 005-S: Skeletonized automatic winding movement with hours, minutes, seconds, date and adjustable rotor geometry.
Dimensions: Length 49.80 mm x 38.00 mm (wide) x 8.25 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 5-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 The watchcase represents the first entrance of new shape with its own particular identity into the Richard Mille Watches collection. It is a counterpoint to the existing collection’s themes of motor sport and sailing, reflected in its discreet lines that are the thinnest in the collection, yet with the same wrist fitting curvature and taper as the rest of the ensemble it represents a further transformation of the tonneau shape suitable for all occasions.
It still retains the same characteristics and attention to detail of case design with a vast number of stamping and machining operations required for the three main components (bezel, middle section and case back). More than 18 days of machine adjustment are required and more than 400 hours of technical research and drawing before production even can start. Each case involves 202 separate machining operations. The design and execution of this watchcase typifies the complete conceptual approach to all parts of the movement, case and dial. As a result, everything has been constructed according to an extremely rigorous specification. 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 30 meters, ensured by three Nitril O-ring seals. The case is assembled with 8 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 per-fect 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 in the numeral 7. 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 titanium, with double seal O-ring and detailing in either 18-carat red or white gold.
DIAL In sapphire (thickness: 0.40 mm) with anti-glare treatment (2 sides), protected by 8 silicon braces in-serted in the upper and lower grooves.
CRYSTAL Bezel side: In sapphire (1800 Vickers) with anti-glare treatment (2 sides). Thickness: 1.20 mm Case back: In sapphire with anti-glare treatment (2 sides) Thickness: at the center 1 mm and outer edges 1.73 mm
