• Stunning new calibre commensurate with Richard Mille’s most complex movements
  
• Two all-new complications: match-phase indicator and goal counters
  
• New case material, Red Carmin Basalt TPT^®
  
• Released in 2 versions, limited edition of 30 timepieces

Richard Mille’s relationship with the world of soccer started with the RM 11-01 and the RM 11-04 Roberto Mancini, which introduced an innovative match-time display. Taking this daring concept even further, the new RM 41-01 Tourbillon Soccer tackles a unique challenge: fully tracking a match through the prism of Haute Horlogerie from kick-off to the final whistle, taking note of every goal.

To bring this vision to life, the Brand began with a blank canvas. The team spent five years developing an entirely novel, patented tourbillon flyback chronograph calibre. Two new complications are introduced here: the match-phase indication and the mechanical goal counter, demonstrating the Brand’s ability to merge sport-specific functionality with advanced mechanical watchmaking.

The RM 41-01 Tourbillon Soccer draws its identity from its new calibre, a clear expression of technical mastery and refined hand-finishing. Developed in collaboration with Audemars Piguet le Locle, the RM41-01 titanium calibre integrates a tourbillon escapement, a 70-hour power-reserve and a function indicator alongside a flyback chronograph with overlapping central minutes and seconds.

The first all-new original complication featured in this watch, the match-time indicator, is located at 9 o’clock and indicates the current phase of the match. Each reset of the flyback chronograph advances the display from 1^st to 2^nd Half, followed by 1^st and 2^nd Overtime. Opposite this window sits the iconic function indicator at 4 o’clock: three titanium plates over a lacquered background display which of the winding, neutral or hand-setting functions is active.

Crafted from microblasted grade 5 titanium, the movement architecture pushes the limits of technical feasibility. Baseplate and bridges are highly skeletonised to provide room for its 650 internal components. On the flyback chronograph side, two column wheels orchestrate a dance of levers and hammers. The chronograph’s overall design ensures a coherent and rational distribution of components without unnecessary layering that favours technical solutions to optimise functions.

Framing the movement, microblasted and satin-finished titanium flanges, a triumph of complex machining, showcase the RM 41-01’s second exclusive complication: the mechanical goal counters. These track the scores of home and visiting teams using the pushers at 2 and 4 o’clock. Each press advances the hands along metallic rails via a dedicated gear train, showing up to nine goals before automatically returning to zero.

This new configuration, which brings together nearly 800 components including the case and the strap, required extensive validation protocols to ensure that the RM 41-01 could withstand all 120 of Richard Mille’s internal shock-resistance tests, including the ultimate 5,000 g’s trial.

Richard Mille brings the concept of skeletonisation to its apotheosis: every bridge, gear, and lever is meticulously optimised to remove unnecessary material. This approach reduces weight and brings to bear an extraordinary number of finishing techniques. Every component of the movement, seen or unseen, offers a level of finishing that reflects countless hours of painstaking handcraftsmanship.

The microblasted bridges feature complex, hand-finished geometries, with PVD coatings to enhance legibility of the calibre’s architecture. Adapting the same finishing, the baseplate receives hand-applied white lacquer to highlight the engraving.

For its part, the minute-counter bridge showcases Richard Mille’s mastery of titanium with its contrasting rounded contours and sharp, linear forms. Microblasted, with hand-polished chamfers prior to PVD treatment, it features graduated angles and straight-grained upper surfaces. This finish is also found on the 5N PVD-treated titanium bridge securing the fast-rotating barrel, itself inspired by the hexagonal pattern of a soccer ball. Contrasting colours and types of finishing emphasise the depth and skeletonisation of the movement.

True to the brand’s identity, the RM 41-01 Tourbillon Soccer prioritises usability and ergonomics. Designed to deliver both comfort and a strong presence on the wrist, the 105-component tonneau-shaped case is presented in two versions.

The first of these introduces Basalt TPT^®, the latest composite developed with North Thin Ply Technology (NTPT™) and derived from the eponymous volcanic rock. Like the dark blue Quartz TPT^® used in the second case iteration and the Carbon TPT^® found on both casebands, Basalt TPT^® combines exceptional mechanical performance with resistance to chemicals and corrosion, thermal stability, and UV resistance.

Aesthetically, Basalt TPT^® presents its own distinct design language. The 40-micron-thick basalt fibres (vs. 30 and 45 microns for carbon and silicon fibres of Carbon TPT^® and Quartz TPT^® respectively), stacked with a 45° rotation between layers, are more visible in the composite, revealing a naturally wood-like grain that can be rendered in deep, rich tones.

Displaying meticulous attention to detail and ergonomics, the pushers are made of microblasted titanium with polished bevels, Carbon TPT^® or Basalt TPT^® inserts and 5N gold guards. Their tactile feedback is uniform across all functions, meaning each pusher requires the same pressure to activate, thanks to precisely calibrated levers and the addition of a dedicated column wheel for the reset function. Normally experienced as very abrupt, this function now delivers the same refined tactile sensation. This innovative double-column-wheel flyback chronograph construction has been patented.

Able to track every minute, every goal, and every stretch of extra time, the RM 41-01 Tourbillon Soccer offers a unique mechanical interpretation of this sport. Blending ingenuity, complexity, and practicality as only Richard Mille can do, the RM 41-01 Tourbillon Soccer continues to push the boundaries of what is technically achievable and what mechanical beauty can express. At Richard Mille, each watch is conceived for extreme technique with zero compromise. Every creation challenges contemporary watchmaking by offering previously unexplored solutions. Performance is not theoretical: it is measured, quantified, and demonstrated in practice.

The RM 41‐01 Tourbillon Soccer translates the dynamics of a soccer match into a mechanical language, with a calibre among the brand’s most complex movements. Capable of tracking every minute, every goal, and every stretch of extra time, this watch offers a unique watchmaking interpretation of soccer.

Blending ingenuity, complexity, and practicality in an unmistakable Richard Mille tradition, the RM 41-01 Tourbillon Soccer continues to push the boundaries of what is technically achievable and what mechanical beauty can achieve.

From the brand’s early days, sport provided a real-world battlefield where performance targets could be defined, tested, and validated under stress. Shock resistance, durability and reliability became engineering requirements dictated by genuine uses of the watch, so that function would always emerge from true necessity.

Richard Mille’s relationship with soccer took shape more than a decade ago, when the brand chose to engage at the heart of the match itself, rather than treat the sport as a mere communication exercise. Soccer’s time is not merely measured, it is structured: regulation halves, extra-time and possible overtime require a display that is visible at a glance.

Introduced in collaboration with renowned soccer manager Roberto Mancini in 2013, the RM 11‐01 was the first Mille watch dedicated to this sport, translating its temporal logic into the prism of Haute Horlogerie with an ingenious sapphire dial indicating the different phases of the match. In 2019, the RM 11-04 refined this concept with the latest materials and calibre optimisation whilst improving efficiency and comfort without altering the core right through of its predecessor.

Taking the concept of a tool watch dedicated to soccer even further, the RM 41-01 Tourbillon Soccer - two creations limited to 30 pieces each - tackles a unique challenge: fully tracking a match via the prism of High-end watchmaking, from kick-off through every goal scored, to the nal whistle.  

The result of ve years of research and development, the RM41‐01 calibre combines an ultra-skeletonised titanium architecture, a tourbillon flyback chronograph, power-reserve and function indicators and, above all, two unprecedented soccer complications: a match-time indicator and two mechanical goal counters.

The RM 41-01 Tourbillon Soccer opens a new chapter, reframing the soccer match as a kinetic experience the wearer can instinctively follow.

Why a new watch dedicated to soccer and why now?
With unbridled creativity, this new creation follows in the footsteps of earlier masterpieces developed by the Brand, such as the RM 031, RM 039, RM 62-01... In the same spirit of innovation, the RM 41-01 Tourbillon Soccer pushes technical and aesthetic boundaries even further, embodying our vision of what a true “unicorn” should be — a product so complex that it breaks all conventions. Ultimately, it is on this demanding battlefield of innovation that we believe our legitimacy must be proven.

Soccer has been part of our story through partnerships with legendary figures Didier Drogba and Roberto Mancini, a player and coach we are proud to call friends. It has also featured in our watchmaking, starting with the automatic RM 11‐01, then the RM 11-04, but we never approached it from a tourbillon perspective. Generally, we develop outstanding, top-tier tourbillon architectures and then derive automatic calibres but with the RM 41‐01, it happened the other way around. We started with the ingenuity of the RM 11‐01 and its dial, pushing the concept much further, both aesthetically and technically, to create a watch capable of trackinghalves, extra time, and goals without compromising readability or ergonomics.

What’s the internal process for obtaining such outstanding architecture and complexity?
We always take a full development approach. Along the way, this watch became one of the most complicated ever developed by the brand. The endeavour was immense: to imagine complications capable of meeting the technical brief, to design a new tourbillon calibre featuring an innovative flyback chronograph mechanism, new complications and to house a multitude of components within a rational, efficient, and aesthetically balanced architecture. Our ambition was achieved through exceptional teamwork.

Where does the RM 41‐01 sit within the brand’s direction?
We think in concepts rather than linear evolutions. What we learn on one reference becomes a basis for the next challenge, whether tourbillon or automatic. The RM 41‐01 Tourbillon Soccer raises the bar for finishing across the entire calibre and sets a template for sports-specific functionality moving forward. The RM 41-01 Tourbillon Soccer draws its identity from its new calibre, a clear expression of technical mastery and refined hand-finishing with 650 components.

Animating this mechanical stadium, the RM41-01 calibre, developed in collaboration with Audemars Piguet le Locle (APLL), integrates a tourbillon escapement, a 70-hour power-reserve and function indicators, a patented flyback chronograph with overlapping central minutes and seconds and two new complications: a match-phase display and mechanical goal counters.

The movement architecture is pushed to the limits of technical feasibility. Crafted from microblasted grade 5 titanium, the baseplate is highly skeletonised to provide room for the 650 internal components. To streamline the mechanism, grade 5 titanium is also used for bridges and levers with PVD treatments in black, blue, and gold that create visual depth and highlights key indications.

The decision to place chronograph seconds and minutes on the same axis is a key factor that guarantees the proper readability of the soccer-specific timekeeping indications on the periphery

Getting into the details of the chronograph architecture, the flyback chronograph features two column wheels. Generally, flyback chronographs require a single column wheel to activate the chronograph system and do not need similar gears to reset the mechanism. However, Richard Mille has developed an additional column wheel to manage the reset function of the chronograph.

This atypical choice is not a frill: it equalises pusher force so that start/stop and reset feel identical under the finger. In practical terms, control becomes uniform and more precise, without having different levels of resistance for different actions. The mechanical design of levers, hammers and gears was tuned to preserve amplitude and stability across cycles, a key factor in reliability over time. This entirely new double-column-wheel architecture has been patented, making this flyback chronograph an exceptionally innovative construction. The pursuit of detail has been a lifelong obsession for the Brand and will continue to be, turning each timepiece into a mechanical sculpture.

Within this miniature realm of titanium, the RM 41-01 Tourbillon Soccer introduces the match-time indicator. Located at 9 o’clock and made of 316L steel with black decal, this indicates the current phase of the match.

Linked to the chronograph by a set of levers, each reset of the flyback chronograph advances the display from the 1^st to the 2^nd half and then to the 1^st and 2^nd overtime. Opposite sits the iconic function indicator at 4 o’clock, which reveals the winding, neutral or hand-setting position by way of three titanium plates that emerge above a lacquered background.

But the ingenuity of the RM 41‐01 Tourbillon Soccer goes even further with its mechanical goal counters. The titanium pushers at 2 and 4 o’clock incrementally tally the score for the home and visiting teams respectively. Each press advances the hands mounted on metallic rails via a dedicated gear train up to a maximum of nine goals; the tenth press zeroes the counter by releasing the spring. The mechanics of the goal counters are hidden beneath the external flange and are designed for repeated actuation.

The system’s tolerances and return forces are calibrated for durability, with each motion validated across cycles to prevent cumulative wear or failure.

Create functions that are intuitive and effortless to use, yet extremely complex to develop is deeply rooted in Richard Mille’s core identity. Behind this apparent simplicity lies an engineering process, where every mechanism is conceived, tested, and refined to achieve absolute performance. Innovation thus serves both function and emotion.

Such a construction required extensive validation to ensure that the RM 41-01 could withstand all 120 of Richard Mille’s internal shock-resistance tests, including the ultimate 5,000 g trial. For the sake of clarity, the purpose of the tests is not merely to reach a specific figure, but also to ensure that repeatable actuation (start, stop, reset, increment, function change) feels the same on day 1 and through the life of the watch.

It is precisely this level of constraint, combined with the mechanical volume and interdependence of the complications, that prompted the adoption of a precision-engineered layout designed to clean sightlines, ensure functional coherence and control the overall thickness and weight.

How complex was integrating the tourbillon flyback architecture with match‐specific indications?
Putting together so many functions, components and brand-new complications is always a great challenge. More specifically, the biggest challenge we faced was integrating all these complications in a very compact volume, while preserving perception of the skeletonisation and the architectural readability of the calibre. With such complex watches, it’s easy to reach information overload and compromise the overall aesthetics. Here, the 650 components of the movement form a harmonious composition, due in part to the calibre’s symmetry.

What is the origin of the glide concept for the goal counters, and how is their robustness ensured?
We wanted to push further and cover the entire spectrum of the sport. Being able to indicate goals was the next step in this journey. We drew inspiration from the number selector of the RM 70-01 Tourbillon Alain Prost, with its rolling mechanism, but we opted for the sliding system on a rail as it was more suitable for this specific design.

Their long-term resistance is ensured by the numerous shock and vibration tests we carry out on prototypes, one reason why we are recognised industry-wide for our component durability.

How was each bridge, gear, and lever skeletonised in the calibre, and what guided the design of this skeletonisation?
We try to skeletonise as many components as possible to reduce the weight of the calibre, and we perform extensive computer simulations on the key parts. In a watch of such complexity, we ensure a finely skeletonised movement that reveals the artistry and precision at its core. The beauty of skeletonisation at Richard Mille lies in the multitude of empty spaces we create within, highlighted by the anglage and allowing light to penetrate to the heart of the calibre. But balance is the key: a piece that is too skeletonised could break under a 5,000g shock; everything is simulated to ensure the proper level of hollowing. There’s a tremendous design effort behind this calibre that called for several iterations.

How remarkable is the handwork required by watchmakers to finish the calibre’s components?
It is extremely remarkable; the minute aspect of some finished components and the quality of execution are impressive. No detail is left unfinished. In a Richard Mille watch, there is no dial to hide a scratch, poorly executed anglage, or an uneven surface. In short, there is no room for error. Every component is refined to the extreme, with polished chamfers, satin-finished or straight-grained surfaces. Every component must be perfect, whether visible or not.

Among all the tests carried out, which is the most difficult?
In addition to the multiple quality controls and tests, the ultimate assessment comes from management approving the finished product on the wrist. When looking at a watch, you can sense when it embodies the full brand’s ethos — when you know you are holding something that faithfully reflects the original concept, meets the specifications, and evokes a genuine emotion. The level of complexity reached by the skeletonisation of the RM 41-01 Tourbillon Soccer is unprecedented and sets a new benchmark at Richard Mille

It is a key part of the calibre’s design language and the radical aesthetic it presents, which reflects its immense complexity. From the very first sketches, the objective was to reduce mass, create open undercuts, and guide entering light while indications and kinematics remain legible at a glance.

The performance achieved by the RM 41‐01 Tourbillon Soccer in terms of total complications and shock resistance is truly remarkable. From a mechanical perspective, removing unnecessary weight from levers and bridges allows for an overall reduction in mass, which increases comfort on the wrist, reduces the inertia of moving components, and improves shock resistance. This final accomplishment is possible only when the shapes of the various components are carefully studied to ensure specific behaviour under stressful conditions.

Consequently, skeletonisation was integrated into design iterations to achieve the desired performance. The RM41‐01 calibre was conceived as a whole, rather than by stacking modules, in order to optimise the number of components, avoid unnecessary layering, distribute elements in a single visual plane wherever possible while limiting overall thickness.

This approach to watchmaking architecture exposes an extraordinary number of edges, all hand-finished. For example, the microblasted bridges feature complex, hand-finished geometries, with PVD coatings enhancing the legibility of the calibre’s architecture. Using the same finishing, the baseplate receives hand-applied white lacquer that highlights the engraving.

The minute-counter bridge showcases Richard Mille’s mastery of titanium, blending rounded contours with sharp, linear forms. Microblasted, with curved arms and chamfers polished prior to PVD treatment, it features evolving angles and straight-grained upper surfaces, a finishing also found on the 5N PVD-treated titanium bridge that secures the fast-rotating barrel inspired by the hexagonal pattern of a soccer ball. The contrasting colours emphasise the depth and skeletonisation of the movement.

Another example is the chronograph hands sweeping across intricately machined titanium anges; microblasted and satin-finished, they reflect the same level of excellence evident in every single component of the movement.

True to the brand’s identity, the RM 41-01 Tourbillon Soccer prioritises usability and ergonomics.

Its 105-component tonneau-shaped case is designed to deliver both comfort and a strong presence on the wrist, with innovation extending seamlessly to the exterior.

The RM 41‐01 Tourbillon Soccer advances Richard Mille’s composite language, introducing a brand-new material and expanding the chromatic and textural palette available at Richard Mille with Basalt TPT^®.

The watch was conceived in two refined configurations, each limited to 30 timepieces, featuring either a Red Carmin Basalt TPT^® or Dark Blue Quartz TPT^® bezel, both mounted on a Carbon TPT^® casebands.

This latest material is developed with North Thin Ply Technology (NTPT™) and derived from volcanic rock. It is made by impregnating 40-micron-thick basalt fibre layers with red-pigmented resin, stacking them at alternating 45° angles, and curing them under heat and pressure. Basalt TPT^®, like Quartz TPT^® and Carbon TPT^®, combines exceptional mechanical performance with resistance to chemicals and corrosion, thermal stability, and UV resistance.

For the second iteration, in Dark Blue Quartz TPT^®, the basalt fibres are replaced with 45-micron silica fibres while retaining the same manufacturing process.

Despite the differing origins of the fibres (silica vs basalt), Quartz TPT^® and Basalt TPT^® preserve the same lay-up and curing logic, relying on the same production process but obtaining two different visual effects. Quartz TPT^® reads cooler and luminous, making it ideal for the blue configuration, while Basalt TPT^® delivers a richer and darker hue and reveals a uniquely wood-like texture that can be rendered in deep, rich tones.

These composite bezels are paired with casebands of Carbon TPT^® built from 30-micron carbon threads, showcasing the versatility of Thin Ply Technology across different materials.

Meticulous attention to detail and ergonomics is evident in the pushers, crafted from micro-blasted titanium with polished bevels and fitted with Carbon TPT^® or Basalt TPT^® inserts, while the pusher guards are made of 5N gold.


The tactile feedback is uniform across all functions, meaning each pusher requires the same pressure to activate, thanks to precisely calibrated levers and the addition of a dedicated column wheel for the reset function, a patented double-column-wheel flyback chronograph construction.

There set pusher now delivers the same refined tactile sensation as other functions. The shape and surface of the pushers, along with the ‘click’ sound that is so clear and unambiguous to finger and ears alike, help to create a feeling of comfort and seamlessness Another material has been developed: what are the limits of Richard Mille’s creativity and NTPT’s knowledge?
There are no limits! NTPT™ is an extremely creative company in composites, constantly innovating in terms of colour, composite combinations and finish. Their TPT^® technology is unique and offers enormous possibilities. It has been 10 years since we introduced Carbon TPT^®, and when you look at the range of cases we have developed until today, you realise that this is only the beginning.

How do Quartz TPT^® and Basalt TPT^® differ in machining and user interaction?
The difference is purely a matter of aesthetics. Both materials are suitable for interactions with human skin. We carried out many tests to verify the safety of Basalt TPT^®. It’s essential for us to ensure unequivocally that every material we use, and every composite we develop, poses no danger to the wearer of the watch. Years of R&D could be wasted if we do not always carry out these controls.

How will Basalt TPT^® be integrated into Richard Mille material portfolio for the future collections?
It is part of the catalogue and will be used according to upcoming projects and what we are seeking. The available catalogue of materials is constantly growing allowing significant interchangeability. To be clear, we can play with colours coming from the different effects in the nature of fibre while maintaining the same performance in terms of lightness and stiffness. Such possibilities are priceless opportunities in always remaining creative.

Mechanical goal counters
The RM 41-01 fully tracks a soccer match, from kick-off and every goal to the final whistle, through the prism of Haute Horlogerie. Each press advances the hand mounted on metallic rails via a dedicated gear train, displaying up to nine goals before automatically returning to zero.

Match-time indicator
The flyback chronograph is linked to a match-time indicator by a set of levers. Each chronograph reset instantly updates the match time indicator from the 1^st half to the 2^nd half and then to the 1^st and 2^nd overtime.

Power-reserve indicator
The power-reserve indicator shows the number of hours of energy left in the mainspring before the watch must be wound again.

Function indicator
It shows the winding, neutral or hand-setting position by way of three titanium plates emerging above a lacquered background.

Calibre RM41-01
It embodies technical mastery and refined hand-finishing, integrating power-reserve and function indicators, a flyback chronograph with a unique match-time display and goal counters.

Power reserve
Around 70 hours (±10%), without chronograph running. Actual power-reserve results will depend on the period of time the chronograph is utilised.

Skeletonised grade 5 titanium baseplate and bridges
These components have been finished in grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the mechanical properties of this material, which explains its frequent use in the aerospace, aeronautics and automotive industries.

The bridges are microblasted and hand-bevelled before receiving a finish with blue and gold PVD treatments.

The baseplate of the calibre RM41-01 has been optimised to achieve an extreme weight/resistance ratio. The skeletonised baseplate and the bridges have been subjected to intensive and complete validation tests to optimise their resistance capacities.

Patented flyback chronograph construction
The architecture of the movement allows for a coherent and rational arrangement of its components. It avoids superimpositions and incorporates technical solutions that optimise its functions.

For instance, the geometry of the column wheels has been carefully designed to ensure perfect synchronisation of the various levers, even over the long term. This design has been implemented to maintain precise regulation and guarantee flawless long-term performance.

To optimize the reset and flyback operations and provide tactile feedback similar to the start pusher, a dedicated column wheel manages these functions. This double-column-wheel construction is unprecedented in a flyback chronograph and has been patented.

The chronograph is linked to a new match time indicator by a set of levers. This indicator displays the phase of play: with each reset, the counter switches from the first to the second half, then to overtime.

Mechanical goal counters
The RM 41-01 features two innovative goal counters, allowing real-time tracking of goals scored by the local team, as well as by the visiting team.

The titanium pushers at 2 and 4 o’clock increment the score for the home and visiting teams respectively. Each press advances the hands mounted on metallic rails via a dedicated train of gear up to a maximum of nine goals; the tenth returns it to zero thanks to the release of the spring.

Function indicator
In a manner similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand-setting positions as the crown is pulled out. An aperture located at 4 o’clock shows the function selected: N (Neutral) - W (Winding) - H (Hand-Setting).

Balance wheel with variable inertia
This type of balance wheel guarantees greater reliability when subjected to shocks and during assembly or dismantling of the movement, thus providing better chronometric results over time. The index is eliminated, thereby allowing a more precise and repeatable calibration using 4 setting screws.

Fast-rotating barrel
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.

Winding-barrel teeth and third-wheel pinion with central involute profile
The central involute profile of the winding-barrel teeth provides an optimal pressure angle of 20°, which promotes effective rotary motion and compensates for possible variations in the operation of the going train. This, in turn, ensures excellent torque transmission and a distinct improvement in performance.

Barrel pawl with progressive recoil
This device permits an appreciable winding gain (around 20%), especially during the start of winding. It is also helpful in ensuring an even distribution of the mainspring’s internal tension.

Spline screws in grade 5 titanium for the bridges and case
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.



The design and execution of the entire watch bear witness to a conceptual approach that encompasses the movement, case and dial as a single whole. As a result, everything has been constructed according to extremely rigorous specifications, in the manner of the analytical engineering methods used in the design of Formula 1 racing cars, where the chassis and the engine are developed in complete harmony.

The tripartite case is water-resistant to 50 metres, ensured by two Nitrile O-ring seals. The case is assembled with 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
