 In our respective domains, we both seek to achieve excellence. We speak the same language, Richard and I. We’re both passionate about our work. Keeping alive this flame of passion for what we do each day is essential to me. It is heart-warming to feel the confidence that he and the teams show in allowing me to participate in this singular adventure,’ shares Rafael Nadal.

While the Calibre RMAL1 of the RM 35-02 already possessed a variable geometry rotor — a signature component of Richard Mille automatic movements —  the butterfly rotor of the RM 35-03 allows the wearer to directly interact with the rotor’s geometry, controlling the movement’s winding speed based on lifestyle and activity levels, for a complication that is playful and practical in equal measure.

Previously, any modification of the rotor’s geometry needed to be done by one of our licensed watchmakers. We have perfected this system and given wearers the possibility of directly acting on the watch’s winding speed,’ explains Salvador Arbona, Technical Director for Movements. ‘It’s like a driver being able to adjust the transmission style from city use to racetrack by activating the sports mode.’

The butterfly rotor consists of two grade 5 titanium arms mounted with heavy metal weight segments, activated by a separate gear train via a dedicated push-piece. In their initial position, the weight segments create a radial displacement of the gravitational centre outward, converting the wearer’s every movement into the torque needed to rewind the barrel.

Press the push-piece at 7 o’clock, however, and the rotor’s gears spread the two weights to a 180° angle. The gravitational centre is aligned and the rotor returns to a balanced position, suspending the winding process and thereby preventing excessive winding of the movement.

In shifting between modes—from the normal mode that winds the barrel spring to the ‘sports mode’ that suspends the rotor’s activity—pressure on the push-piece prompts the function to deliver haptic feedback, allowing the wearer to actually feel the weight segments springing apart on their wrist.

A winding indicator at 6 o’clock on the dial, shows whether the oscillating weight is active (ON) or not (OFF). Rounding off the movement commands is a function selector. At a press of the push-piece at 2 o’clock, the user may shift between winding (W), neutral (N) and time-setting (H) activities.

Athletic and ergonomic in its lines, the RM 35-03 is available in three versions—blue and white Quartz TPT ®, Carbon TPT® and white Quartz TPT®, and Carbon TPT® - featuring cut-outs inspired by the RM 27-04 Tourbillon. Entirely skeletonised, the movement can be admired from both sides thanks to sapphire crystals on the front and back.

The baseplate and bridges, crafted of grade 5 titanium with a grey electroplasma and PVD treatment, further accentuate the bold visual statement ofthis watch. The openwork hands sweep along the outer flange, also in microblasted grade 5 titanium, punctuated with the numbers 3, 6, 9 and 12 and slanted inward towards the movement to enhance depth.

RICHARD MILLE – RM 33-02 Carbon TPT®-Gold Edition


RICHARD MILLERM 33-02 Carbon TPT®/Gold Automatic Edition 2019

A Combination Of ‘Lifestyle And Sporty Style

By marrying the performance of a sports watch with the elegance of a round timepiece, Richard Mille has successfully merged two diametrically opposing characteristics. Overseen by Julien Boillat, the Richard Mille watch exteriors teams have reinterpreted the collection’s first ultra-thin round watch: the RM 033, which was introduced in 2011.

Click, to see the large size. BIG FOTO

We believe it is both essential and logical to pay the same care and attention to evolving our collections as to the original creation of our models. In embodying the brand’s intended vision of extreme versatility, the RM 033 is a watch for everyday and any day. We have reinterpreted its aesthetics without disservice to the original version by accentuating its lines. Meanwhile, the exterior decoration, case and dial have been reworked to project a sportier vibe. The RM 33-02 thus achieves a delicate synthesis of so-called ‘lifestyle’ style and sporty style,’ shares Julien Boillat.

Click, to see the large size. BIG FOTO

The taut lines of the case combine the curves of a tonneau shape and the elegance of a round form with a subtle allusion to sporty style in the design of the hollows. This first round Carbon TPT® automatic watch exhibits a Carbon TPT® bezel and caseback alongside a satin-finished red gold caseband.

The design of the strap prolongs that of the two indentations positioned unusually at 6 and 12 o’clock in a highly original way. These new vanishing lines also contribute to the dynamics of this already extremely bold case.

Click, to see the large size. BIG FOTO

The sporty, round, ultra-thin RM 33-02 timepiece is powered by the skeletonised RMXP1 calibre in grade-5 titanium. Regulated by a variable-inertia balance oscillating at 3 Hz, this calibre is wound by an off-centre platinum micro-rotor that considerably reduces the movement’s total thickness to 2.60 mm. Yet this thinness in no way inhibits the architectural expression intrinsic to the brand.

Click, to see the large size. BIG FOTO

The wet sandblasted and Titalyt®-treated baseplate, the microblasted, stretched and satin-finished surfaces, and the anglage — all produced entirely by hand — accentuate volumes by playing with shadow and light thanks to the highly graphic skeletonisation.

The exterior elements and hour-markers further add to this complex sense of depth and power. In 5N gold hour-markers on two rigid titanium rails fixed between the flange and the movement. The dial, which spans the entire calibre, accentuates the volumes while the typography of the oversized numerals adds a dynamic element to the watch’s easy readability.

By juxtaposing soft gold with strength Carbon TPT®, and by combining the graphic codes of the lifestyle and sports spheres for both male and female, Richard Mille clearly communicates a desire to combine allegedly contradictory worlds within a single watch. The RM 33-02 Automatic is available as a limited edition of 140 timepieces.

RICHARD MILLE – RM 50-03 Tourbillon McLaren F1 Edition


ICHARD MILLE RM 50-03 Tourbillon Split Seconds Chronograph Ultralight McLaren F1 Limited Edition

THE WORLD’S LIGHTEST SPLIT-SECONDS TOURBILLON CHRONOGRAPH:
RM 50-03 McLAREN F1

Relentless technical innovation, the quest for perfection, and a perpetual hunger for progress are the common factors that link McLaren-Honda and Richard Mille.


Produced in collaboration with the famed Formula 1 constructor, the new Richard Mille calibre is a technical masterpiece offering off-the-chart mechanical performance.

The RM 50-03 tourbillon split seconds chronograph ultralight McLaren F1 weighs less than 40 grams – including the new strap – which makes it the lightest mechanical chronograph ever made.
This landmark has been achieved through the use of cutting-edge technical materials. The design not only incorporates Titanium and Carbon TPT™, but also introduces an entirely new material into the world of watchmaking: Graph TPT™, more commonly known as graphene.


Click, to see the large size. BIG FOTO

These new applications for the material emerged through research at the National Graphene Institute, established in 2015 at The University of Manchester. It’s where graphene was first isolated by Professor Andre Geim of the School of Physics and Astronomy, back in 2004. Six years later, the discovery earned its author the prestigious 2010 Nobel Prize in physics, alongside his colleague, Professor Konstantin Novoselov.

Thanks to the collaborative work between The University of Manchester, McLaren Applied Technologies and North Thin Ply Technology (NTPT®), Richard Mille has succeeded in producing a watch case machined in an improved form of Carbon TPT™.

The carbon’s physical properties were significantly enhanced by the introduction of graphene, a revolutionary nano-material which is six times lighter than steel, and 200 times stronger. McLaren Technology Group and McLaren-Honda, which are currently working on integrating graphene into their Grand Prix cars, made it possible for us to consider this material as a means to significantly low the density of our carbon composite while increasing its resistance.

Convinced of the incredible advantages conferred by graphene, our engineers worked with those at North Thin Ply Technology to envision practical applications of the new material, and studied how to incorporate it into Carbon TPT™.

Noted for the beautiful, undulating striations of its surface, Carbon TPT™ is comprised of parallel filaments – 600 layers, in fact, whose maximum thickness is 30 microns. These are impregnated with a super-charged resin containing graphene, and are then compiled by a CNC machine that shifts the orientation of the fibres by 45° between layers.

Click, to see the large size. BIG FOTO

The composite is then solidified by heating it to 120°C, at 6 Bar of pressure. Numerous control and validation tests conducted by McLaren Applied Technologies have made it possible to develop the solutions that resulted in the production of Graph TPT™, a material employed exclusively by Richard Mille in the domain of watchmaking.

At the Richard Mille manufacturing facility, our team specialising in the machining of movement components and cases turned their attention to manipulating Graph TPT™ — spending many long hours creating and programming cutting tools suitable for achieving precision to a micron.

The resulting three-part case cedes ground nowhere, being both highly resistant and extremely light, while preserving perfect ergonomics and a unique, striking appearance.

For its part, the 7-gram movement completely deserves the qualifier ‘ultralight’. The secret to its feather weight lies in the use of grade 5 Titanium and Carbon TPT™ for the baseplate and bridges, and in the extreme skeletonisation of components. Likewise, the density, stiffness and low thermal conductivity of Titanium make it a material of choice in McLaren Racing’s Formula 1 engineering build programme, where it’s not only used to lighten and reinforce chassis and aerodynamic elements, but also to produce gearboxes, connecting rods and valve systems.

Click, to see the large size. BIG FOTO

Watchmaking expertise can be found throughout this movement with drawn, polished, satin-finished and soft-polished surfaces all created by hand. For example, each grade 5 titanium dial requires
3 hours of anglage and polishing in our workshop to highlight its edge. Other parts, such as the barrel-drum, the minute-wheel and the small and large medium-wheel are circular grained both above and below then hand-beveled and rhodium plated before the teeth are cut

A transverse cage, crafted of Carbon TPT™ and inspired by the wishbone suspension structure of a McLaren-Honda Formula 1 car, is affixed to the caseband, and supports the entire RM50-03 calibre. By eliminating the casing ring, this unusual architecture enables a perfect fit between the movement and case. Taken together, these technical solutions provide the complex calibre with tremendous resistance properties. Indeed, the casing has withstood shock loadings of 5,000g in our own workshops – and survived unscathed.

The RM 50-03 McLaren F1 is chronographic perfection brought to life: it combines a tourbillon escapement with a split-seconds function. In order to perform without fail, the combination of these two complications within a single mechanism demands perfect transfers of energy. The ensuing need to reduce friction led to research on how to improve the profiling of the teeth on the barrel and gear train. The result is superbly balanced torque and optimised yield.

Click, to see the large size. BIG FOTO

The movement’s performance and the quality of the energy delivered can be easily read via coloured indicators denoting the 70-hour energy reserve and torque sensor. The hollow pushers of the chronograph are representative of the air intake ducts on the McLaren-Honda car, while the shape of the crown takes its cue from the racing competition wheel rims used by the British team.

Design of a new split-seconds mechanism and extensive research on the work of the split-seconds clamps have permitted a 50% reduction in the chronograph’s energy consumption, while at the same time reducing arbor friction. The 6-column wheel that controls the various rockers for the split-seconds function was designed to guarantee flawlessly simultaneous movement, clean function lock, and highly stable settings.

The extraordinary properties of graphene encouraged us to pursue additional developments in conjunction with our strap supplier, BIWI S.A., and to incorporate this nano-material into the rubber strap of the RM 50-03 to increase its elasticity and resistance to wear. These various applications of graphene represent significant technical advances that are of capital importance for both Richard Mille and McLaren-Honda.

The RM 50-03 McLaren F1 will be produced in a numbered limited edition of 75 pieces and will be available only at Richard Mille boutiques. Each watch will be accompanied by a 1:5 scale model of the McLaren-Honda racing car driven in 2017 by Double-World Champion Fernando Alonso and Stoffel Vandoorne.

TECHNICAL SPECIFICATIONS

RM 50-03 TOURBILLON SPLIT SECONDS CHRONOGRAPH ULTRALIGHT McLAREN F1

Limited edition of 75 pieces made from Graph TPT™.

MAIN FEATURES
CALIBRE
Manufacture Calibre RM50-03
Manual winding tourbillon movement with hours, minutes,
split-seconds chronograph, 30-minute totaliser, and power-reserve, torque and function indicators.
Dimensions : 44.50 mm x 49.65 mm x 16.10 mm.
POWER RESERVE
Around 70 hours (±10%), displayed on a numeric scale at 11 o'clock.

ULTRALIGHT TOURBILLON CALIBRE IN TITANIUM AND CARBON TPT™

The RM50-03 calibre weighs just 7 grams. This record-breaking weight was obtained by using high-tech materials and by skeletonising its components as far as possible.

The baseplate and bridges in grade 5 titanium are highly resistant to corrosion and remarkably rigid, enabling the gear train to function effortlessly. This alloy (90% titanium, 6% aluminium and 4% vanadium) enhances the mechanical properties of the latter.

Some of the bridges of the split-seconds chronograph are made from Carbon TPT™, as is the transverse carriage that supports the entire calibre together with the barrel and tourbillon bridges. Attached to the caseband, this carriage circumvents the need for a casing ring, allowing the movement to be ideally integrated into the case.


All of these technical solutions give this complex calibre, with its extreme weight to resistance ratio, an impressive resistance capacity, tested in our workshops to shocks of 5,000 g.

NEW SPLIT-SECONDS SYSTEM

The RM50-03 calibre introduces a latest-generation split-seconds mechanism developed by the Richard Mille engineers. The new column wheel operates the different levers of the split-seconds function and optimises the chronograph's operation. While previous Richard Mille chronographs have traditionally featured a wheel with 8 columns, the one equipping the RM 50-03 now only has 6 columns to ensure optimised simultaneous movement, maximal function locking, and greater adjustment durability. In-depth studies carried out on the function of clamps also led to a new clamp design. The helical spring has also been replaced by a blade on the split seconds wheel of the RM 50-03, a technical decision that reduces the variation in torque when the split-seconds function is activated.

Click, to see the large size. BIG FOTO

All of these developments have considerably improved the timekeeping performance of this tourbillon calibre and have halved the chronograph's energy consumption while reducing friction on the arbors.

Use: the pusher at 8 o'clock starts or stops the seconds hand of the chronograph. The pusher at 4 o'clock stops the split seconds hand and allows an intermediary time to be read off while the chronograph is engaged. When this pusher is pressed again, the split-seconds hand catches up with the chronograph hand and simultaneously continues its course. The pusher at 10 o'clock resets the hands.

TORQUE INDICATOR

This function indicates the tension of the mainspring and makes it possible to optimise the winding of the watch. Under 53 dNmm, the spring is too slack. However, over 65 dNmm, the excessive tension could affect the operation of the mechanism, or even damage it. (These indications appear on the numeric scale to the right of the barrel).

FUNCTION INDICATOR

When the crown is pulled out, the hand indicates winding, hand setting or the neutral position, similar to the gearbox on a car. A hand at 4 o'clock displays the selected mode: W (Winding) – N (Neutral) – H (Hand Setting).

FREE SPRUNG BALANCE WITH VARIABLE INERTIA

This type of balance ensures greater reliability in the event of impact and during the assembly and disassembly of the movement. The watch's long-term precision is therefore improved. The regulator index has been removed and more precise and repeatable inertia adjustment can now be made using four adjustable weights.

FAST ROTATING BARREL 
(6 hours per revolution instead of 7.5 hours)

This type of barrel has the following advantages:
  • The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby improving performance.
  • Excellent delta of the mainspring curve with a power reserve that ideally balances performance and regularity.
BARREL PAWL WITH PROGRESSIVE RECOIL

This device permits an appreciable winding gain (circa 20%), especially at the start of winding.
It also helps to distribute the internal tension of the mainspring correctly.

TEETH OF BARREL AND THIRD WHEEL PINION 
WITH CENTRAL INVOLUTE PROFILE

The central involute profile of these teeth exerts pressure at an optimal angle of 20°, which enhances the efficiency of the gear train and compensates for any potential variations in penetration. This results in excellent torque transmission and a noticeably improved performance.


MODULAR HAND SETTING MECHANISM ON CASEBACK

This presents the following benefits in terms of longevity and maintenance:
  • As this module is assembled outside of the movement, it can be replaced without touching the baseplate during a procedure or maintenance operation.
  • The assembly and disassembly of this module from the back does not require the removal of the hands nor the dial.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES

The design of these screws permits better control of the torque applied during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

CASE IN GRAPH TPT

The bezel and case back feature Graph TPT™, an Carbon TPT™ whose physical properties have been considerably improved by the injection of graphene, a revolutionary nanomaterial that is six times lighter than steel but 200 times more resistant.

Thanks to the collaborative work between The University of Manchester, McLaren Applied Technologies and North Thin Ply Technology (NTPT®), Richard Mille has succeeded in producing a watch case machined in an improved form of Carbon TPT™. Numerous control and validation tests conducted by McLaren Applied Technologies have made it possible to develop the solutions that resulted in the production of Graph TPT™, a material employed exclusively by Richard Mille in the domain of watchmaking.

With its distinctive, wavy graphic structure, Carbon TPT™ is made up of 600 layers of parallel filaments obtained by separating out carbon fibres. These layers, each a maximum of 30 microns thick, are impregnated with a graphene-containing resin. They are then assembled using a specific machine, which stacks the layers by varying the orientation of the fibres by 45° between two layers. The composite is then hardened in a kiln heated to 120°C with a pressure of 6 bars.

At the Richard Mille manufacturing facility dedicated to machining movement parts and cases – were tasked with machining the Graph TPT™, following many hours spent developing programmes and producing adapted cutting tools to give a machining precision accurate to the nearest micron.
The case of the RM 50-03 is water-resistant to 50 metres thanks to two Nitril O-ring seals. The case is assembled with 20 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.
