TECHNICAL SPECIFICATIONS OF THE SPLIT SECONDS CHRONOGRAPH RICHARD MILLE RM 004-V2 For the first time in watchmaking history and after years of research and development, a movement baseplate in carbon nanofiber has been created. This innovation was first tested with great success on the RM 006, an experimental model. The technical results were remarkable and this led to the extended use of carbon nanofiber in the RICHARD MILLE tourbillon range, as well as in the split seconds chronographs. Progress in this important area of development has now opened up a new era in watchmaking. CALIBER RM 004-V2: Manual winding movement with hours, minutes, chronograph, split seconds, 30 minute totalizer, power reserve indicator, torque indicator, function indicator. Dimensions: Length 48 mm x 39.00 mm (widest point) x 15.05 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. CHRONOGRAPH (column wheels in titanium) The modern architecture of this movement has allowed for the consistent and rational arrangement of its constituent parts, avoiding unnecessary superimpositions and permitting the best possible use of the functions with technical solutions. For example, research was conducted into the geometric design of the column wheel that controls the different levers to ensure the perfect, long-term simultaneity of the functions, a feature that is essential for a high performance chronometer. This design was implemented in order to achieve a high degree of continuity in setting, combined with an unfailing repeatability of the various functions. Operation: The user can start or stop the chronograph function via the pusher located on the lower left at 8 o’clock. The hands are reset by pressing another pusher located on the upper left at 10 o’clock. SPLIT SECONDS MECHANISM with improved performance One of the new characteristics developed for the RM 004-V2 is the virtually complete elimination of initial jumping in the chronograph seconds hand. A great number of studies led to the design and manufacture of gear wheels and levers in titanium, thus reducing inertia. Moreover, the development of a new generation of split seconds components meant that energy consumption could be lowered by approximately 50% by reducing friction on the spindle, as well as eliminating the effect of jumping when stopping, thanks in particular to research that focused on the working of the split seconds arms. Operation: simply by pressing the pusher on the right (at 4 o’clock), the user can stop the split seconds hand in order to read an intermediate time while the chronograph is engaged. Pressing the pusher again allows the split seconds hand to rejoin the chronograph hand. TORQUE INDICATOR This indicator supplies information about the tension of the mainspring, and allows the optimalization of the chronometric functioning of the movement. Below 53 dNmm, the spring is considered to be too slack, while above 65 dNmm, the excessive spring tension can adversely affect the mechanism’s operation, or else actually endanger it. These indications appear on the numerical zone to the right of the barrel. BALANCE WHEEL WITH VARIABLE INERTIA This type of balance wheel, which represents the ultimate in innovation, guarantees greater reliability when subjected to shock and also during assembly and dismantling of the movement, thus achieving better chronometric results over time. The index is eliminated, thereby allowing a more precise and repeatable adjustment. 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. BALANCE SPRING Developed in the 18th century, perfected and codified in the 19th, the specially calculated curvature of the balance spring provides excellent chronometric results in tourbillon escapements. CLOSURE OF THE BARREL COVER USING EXCENTRIC SCREWS This development is again part of the intention to make servicing easy, logical, and of a very high mechanical standard. 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. TEETH OF BARREL AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE The wheel with a central developing profile and a pressure angle of 20° promotes rolling movement more effectively, compensates differences between centers, ensures excellent torque transmission and a distinct improvement in performance. OTHER FEATURES CENTER BRIDGE: in titanium MOVEMENT DIMENSIONS: 30.20 x 28.60 mm THICKNESS: 8.90 mm DIAMETER OF THE BALANCE WHEEL: 10 mm NUMBER OF JEWELS: 37 BALANCE WHEEL: GLUCYDUR, 2 arms 2 MOMENT OF INERTIA: 11.50 mg cm , lever angle 53° FREQUENCY: 21,600 vph (3 Hz) BALANCE SPRING: ELINVAR by Nivarox SHOCK RESISTANCE: KIF Elastor KE 160 B28 BARREL SHAFT: Steel sandwich, 20 AP 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 GEAR WHEELS - Concave chamfering with a diamond tool - Circular finished faces - Gilded (before cutting the teeth) - Minimum correction applied to the wheels in order to preserve geometry and performance.

Who's who

When he talks about Richard Mille, Laurent Picciotto doesn’t say “I” and “he”, but “we”. Just two letters say it all – well, almost. As far as Chronopassion is concerned, this is not about any old brand, but a shared history: that of two men who originally met in Rue Saint Honoré “to chat together for a couple of hours a week – then, five, ten, twenty or thirty hours,” before bringing out the first RM001 one year later. Be that as it may, the friendship between Laurent Picciotto and Richard Mille doesn’t stretch back for decades, to their schooldays, or anything like that. “We first came across each other at the time when Richard was working at Mauboussin, on the first tourbillons developed by the brand,” recalls the owner of Chronopassion. When – as yet unaware of the fact that he was to become “RM” for the world at large – Mille left Mauboussin to launch his own brand, he consulted Laurent Picciotto. Not only did he consult him, he took on board his thinking, and ultimately enlisted Picciotto as a partner when he set up his company. The brand spirit was already in their minds – an uncompromising timepiece, featuring a completely new design, outstanding materials and a brand new assembly technique. Once the specifications had been established, the two men contacted Renaud & Papi to implement production. They were to become RM’s third partner; today, some fifteen years later, they are still crafting its collections. The line taken ahead of presentation of the first timepiece was equally hard-nosed. “Nobody knew Richard, we didn’t really want to make a big thing out of Renaud & Papi and we ourselves had no story to tell at all. In other words, we were swimming completely against the tide,” recalls Laurent Picciotto. “We first attended BaselWorld in 2000. We placed the watch on the table and said ‘There you are, that’s all we’ve got to say, it’s an RM001, yours for €176,000.’ And it worked.” Indeed, the pricing policy was the subject of much debate, right from the outset. “Looking back, it’s easy to say that the approach was the right one,” explains Laurent Picciotto. “But twelve years ago, we’d sometimes break out in a cold sweat thinking about it. Richard and I were both completely focussed on the watch, scarcely paying attention to the final bill until the first one was finished. When we totted it up and it came to over 170,000 euros, there was a bit of a hush. The silence between us was far more eloquent than any number of words could have been. For a while we wondered whether we had overreached ourselves. But it wasn’t long before we were right back with our initial motives – an RM should brook no compromise.” Richard Mille did not hesitate to take this radical approach right to the limit. “When he met a client who had doubts about how sturdy the RM was – whereas that had always been a strong point in its design – Richard would take off his own and throw it on the floor. That was his way of saying ‘I’ve said as much, and now I’m proving it’”, recalls Laurent Picciotto with a smile. “It would certainly make quite an impression!” Looking back, the Richard Mille brand has surpassed even its own designers’ expectations. Having emerged at a time when the market was not yet offering a new brand or revival every couple of months, it surprised everybody. Later on, a lot of independent watchmakers took a similar direction, saying to themselves “If Richard has managed, I can too.” RMs are still as radical as ever, though. Laurent Picciotto sums it up. “Some signs never lie. We’ve never yet seen a client pick up an RM whose first words were ‘it reminds me of a...’ Some fifteen years on from the RM001, nobody’s got anywhere near finishing that sentence.” Journalist : Olivier Müller (11/2012)
