Hysek is making its mark on the watchmaking scene – in a decidedly big way.Colossalis a 100% in-house Grande Complication piece, of which only eight are being made – a perpetual calendar in which every display uses a roller. The unprecedented piece boasts over 1,000 components, took three years to develop, and is protected by several patent applications.

Colossal is a major Grande Complication piece boasting unprecedented technology – the most ambitious undertaken by the manufacture in over ten years. Colossal is a watchmaking Everest, celebrating our Maison’s twentieth anniversary in style – as well as commemorating the tenth anniversary of one of our original creations, the Colosso,” explains Hysek CEO Akram Aljord.

Unveiled at Baselworld, the Colossal embodies a disruptive watchmaking vision, bringing together three concepts much beloved of Hysek: Jumping Hours, a Jumping Perpetual Calendar, and a three-dimensional Moon Phase. Together, they bring to life one of the most complex vertical linear displays ever constructed – as well as providing what is undoubtedly one of the most readable Perpetual Calendars around.

The 23:59 challenge

Linear displays – especially ones involving a jumping mechanism – are little short of impossible, technically speaking. The main difficulty with displaying hours and minutes has been that of transposing a flat display to the roller-based system. Simply put, this involves transitioning from a circular display using flat gears to a linear display using vertical gears.




































One that barrier had been overcome, Hysek then set out to resolve one of the most insidious challenges with roller displays: the shift from 23:59 to 00:00.

Logically speaking, the hour unit roller (the “3” in 23:59) should continue on its course to display a 4; but that would end up displaying the non-existent time of 24:00, inevitably followed by 25:00, and so on.




























To prevent that, Hysek has developed an exclusive system that is a world first. A few minutes before midnight, the roller discreetly moves backwards from “3” to “9”, so that it can then jump, appropriately enough, to “0” – such that midnight is properly displayed. As the midnight hour approaches, a veritable mechanical ballet worthy of an automaton takes the stage. Arms, levers, and gears move into position so that the two hour discs roll into place simultaneously at midnight, in complete unison.
































The spectacular jump is the final outcome of a mechanical process that begins much earlier, ensuring that the show at midnight is perfectly coordinated – and goes off without a hitch. A patent has been filed for the reverse-and-forward roller system.

A Moon Phase unlike any other in watchmaking

Occupying as it does a central place in the Colossal’s WH80 caliber, the Moon Phase could hardly content itself with being traditional when all the surrounding complications were so innovative, and indeed developed specifically for this piece.

Click, to see the large size. BIG FOTO










































In this display, the Moon itself is fixed, and encompassed by a cupola in constant rotation. The result is a display comprising two parts: the Moon in the middle and a dome above it. As this dome revolves, it gradually reveals the different phases of the moon. The cupola completes a complete 360° rotation in 29.5 days, with all the regularity of the actual lunar cycle.

This design posed a twofold problem. The first aspect involved actually inventing a Moon Phase of this type in the first place; no such complication had ever been devised. The other aspect of the problem was that the complication does not simply involve a rotating disc but an entire dome. As a result, a suitable ceramic ball bearing system had to be developed.

Beyond the Perpetual Calendar: still more complications

Colossal also features three other complications: a dual time zone, a power reserve, and a seasonal day-night indicator. Hysek has clad the essential hours, minutes, and calendar complications in black, whilst the other complications are rhodium-plated.

Click, to see the large size. BIG FOTO










































The GMT display takes the form of a disc placed atop the seasonal roller, powered by the vertical shaft on which the roller rotates. This solution saves a considerable amount of space, and is right in keeping with the Colossal’s style codes – without adding any particular mechanical complexity. The GMT complication is exactly the same diameter as the roller, as though the two worked in tandem, whereas in fact they are technically separate.

The power reserve and seasonal day-night indicator are displayed on the side of the watch, through two sapphire crystal windows. This side display is a legacy feature of the Colosso that Hysek is proudly using once again, giving it a new, creative, and more technical lease of life. The display in question also enhances the Colossal’s three-dimensional aspect.

Tourbillon, automatic winding mechanism, and twin barrels

The Colossal is regulated by a flying tourbillon, not least for its aesthetic qualities. The tourbillon cage is assembled on ceramic ball bearings.

For optimum comfort, Hysek has chosen an automatic winding mechanism, featuring a micro-rotor made of platinum. This material is both rare and precious – as well as offering an excellent moment of inertia for its size. In addition, two barrels, arranged side by side, work in parallel, providing a 42-hour power reserve. Winding and unwinding at the same time, they deliver sufficient power to trigger all the functions – especially important when various rollers have to jump forward at the same time.

RICHARD MILLE – RM 50-03 Tourbillon McLaren F1 Edition















RICHARD 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.

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.

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.

OTHER FEATURES

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.
TORQUE LIMITING CROWN
This additional security system prevents accidental overwinding, which could cause damage to the winding stem or put extreme pressure on the mainspring barrel.
UPPER AND LOWER FLANGES
In Carbon TPT™ filled with an approved luminescent coating.
DIAL
In grade 5 titanium with black galvanic treatment.
BEZEL AND CASE BACK
Bezel side: sapphire crystal (1,800 Vickers) with anti-reflective treatment (on both sides)
Thickness: 1.10 mm
Case back side: sapphire crystal with anti-reflective treatment (on both sides)
Thickness: 1.00 mm
RUBBER STRAP INJECTED WITH GRAPHENE
Thanks to Richard Mille's partnership with BIWI SA, a Swiss company specialised in very-high-precision moulding of vulcanised elastomers, graphene was injected into the rubber strap of the RM 50-03 in order to improve its rubber-like behaviour and thus its resistance to wear.

ANGELUS – U21 & U22 Tourbillon Limited Edition


















ANGELUS URBAN U21 & U22 Tourbillon Limited Edition

Angelus introduces two new versions of its
Skeleton Tourbillon movement: the U21 and U22.

Marking a new chapter in Angelus’ Urban Collection of cutting-edge watchmaking, the U21 and U22 Tourbillon revisit the singular movement and streamlined design focused on structural optimization with two new executions: the U21 and U22.

Marking a new chapter in Angelus’ Urban Collection of cutting-edge watchmaking, the U21 and U22 Tourbillon revisit the singular movement and streamlined design focused on structural optimization with two new executions: the U21 and U22.

Click, to see the large size. BIG FOTO










































From the movement to the case design, the objective from the get-go has been to showcase the splendor of the movement’s architecture and tourbillon while reducing as much weight as possible. For this purpose, the U21 and U22 Tourbillon feature a carbon fiber main plate, giving the impression of being a part of the case.

Click, to see the large size. BIG FOTO










































The U21 Tourbillon interprets the uniquely structured movement in a noble metal case, combing the bezel-less carbon fiber central case element with polished and satin-brushed 18-karat red gold lugs, enhancing its visual appeal. The skeletonized bridges are solid 18-karat red gold for additional harmony between the case and movement. To further enhance legibility, the hands are filled with white SuperLumiNova.

Click, to see the large size. BIG FOTO









































The U22 Tourbillon on the other hand features a carbon fiber and titanium case like the original U20, however with an even greater emphasis on weight reduction. Thanks to its carbon fiber main plate, the U22 Tourbillon weighs a mere 54 grams in total. The flange ring has also been revisited, set with satin-finished applied indexes for the hour markers. The central hands offer a racy look thanks to the red SuperLumiNova.

The goal with these U21 and U22 Tourbillon is to present the essence of the movement by removing any superfluous material. What seems to look deceptively simple to achieve requires great artistic vision and engineering prowess. The more material that is removed, the more the structure of the movement has to be carefully calculated to ensure rigidity and sturdiness for a maximum precision.

Click, to see the large size. BIG FOTO










































The tourbillon even goes a step further. It does not boast an ordinary movement that has been skeletonized afterwards, but a tourbillon movement that has been created from scratch to be as open, three-dimensional and resplendent as possible.

Click, to see the large size. BIG FOTO






























The discerning eye will be pleased to discover that haute horlogerie has not been sacrificed on the altar of minimal mass: components have been hand-chamfered, hand-polished and hand satin-finished to ensure that they look as good as they are filigree.

And to further increase visibility into the top of the three-dimensional movement, both models features a unique design element. The case is fashioned without a bezel and instead uses a sapphire crystal dome, which also allows a sideways view onto the movement.

The U21 and U22 Tourbillon deserve closer inspection, which reveals many of the well-thought-out details that go into creating a contemporary, cutting-edge skeleton watch: the variable inertia balance wheel of the tourbillon is especially designed and crafted to minimize air friction; the patterned carbon fiber used in the main plate is offers maximum rigidity; ruby bearings are set into solid gold chatons. The ultra-light case, entirely made of carbon fiber, red gold or titanium and sapphire, has been designed to echo the three-dimensional aspect and the technical feel of the timepiece.

The U21 and U22 Tourbillon in detail

The absence of a dial and the use of a sapphire crystal dome set directly onto the carbon fiber case allow full visual access to the movement from both the top and sides, accentuating the three-dimensionality of the movement’s architecture.

Click, to see the large size. BIG FOTO











































The red gold or titanium lugs, which are securely attached to the carbon fiber case and reinforced with an armature of carbon fiber, have a very technical shape and echo the titanium bridges of the movement. However, the intricacy of the lugs is softened by the clever use of polished chamfered edges and contrasting satin-finished surfaces.


Special carbon fiber main plate

The carbon fiber used in the U21 and U22 Tourbillon is very specific, offering the essential characteristics necessary for use in a haute horlogerie timepiece, with tolerances in the micron range. They are not decorative elements, but 100% functional

Movement elements

The heart of the U21 and U22 Tourbillon is the flying tourbillon. The tourbillon is “flying", which means that it does not require an upper supporting bridge. This helps to maximize the three-dimensionality of the movement and allows maximum appreciation of the technical and aesthetical refinements throughout the movement.

Click, to see the large size. BIG FOTO































The tourbillon’s steel cage is hand chamfered and polished with flat surfaces either mirror-polished or satin-finished.

The variable inertia balance wheel is regulated by four gold weights around its perimeter. In the quest for high performance, the rim of the balance wheel has been milled to maximize aerodynamics and reduce air resistance.

The highly engineered movement further features beam-type titanium bridges, which are skeletonized to reduce weight and offer a better view of the watch’s inner workings.

The titanium mainspring barrel bridge is supported by slim pillars set directly into the carbon fiber main plate, a feat in itself that requires great precision and a total functionality of the carbon fiber main plate.

All wheels throughout the entire gear train have a specially developed six-spoke design, again in the quest for maximum rigidity for minimum mass.

All of the rubies, which actually act as low-friction bearings, are fitted into solid gold chatons that are embedded in the carbon fiber main plate. Gold chatons not only look good and attest to the movement's haute horlogerie bona fides, they are also non-magnetic and corrosion resistant like the carbon fiber itself. Their functional purpose is to compensate for the slight deformation due to the driving of the jewels in the main plate and prevent the rubies or carbon fiber from breaking.
