From skeletonised movements to double tourbillons and the audacious Quatuor with four balances, every timepiece is a technical marvel that doubles as a work of art. This blog takes you on a deep dive into the most remarkable innovations of the Roger Dubuis watch collection for men. So, here we are going to explore how Roger Dubuis blends performance, precision and theatre to redefine haute horlogerie for modern collectors.

The Excalibur DNA — manufacture and design

The collection of Roger Dubuis Excalibur has established itself as one of the most recognisable lines in haute horlogerie, due to its bold design codes and uncompromising craftsmanship. Its identity is defined by signature elements such as the fluted bezel, the triple-lug construction, and the striking star-shaped bridge motif. These features set the Excalibur apart visually as well as reflect the maison’s philosophy of merging avant-garde aesthetics with mechanical ingenuity.

At the heart of every Excalibur lies 100% in-house movements, developed and manufactured at Roger Dubuis’ facility in Geneva. This ensures complete control over design, engineering, and finishing, with many models proudly carrying the prestigious Poinçon de Genève certification. Such dedication guarantees both technical precision and artisanal excellence.

Skeletonisation — more than looks

Thanks to its distinctive design codes and uncompromising craftsmanship, the Roger Dubuis Excalibur collection is instantly identifiable. At first glance, the signature triple-lug construction, the bold fluted bezel and the iconic star-shaped bridge motif set the tone for a watch that is as much a piece of contemporary art as it is a mechanical instrument. However, Excalibur is not just about aesthetics — it is built on a foundation of pure horological expertise. It is powered by 100% in-house movements conceived and manufactured at Roger Dubuis’ state-of-the-art facility in Geneva.

One of the defining features of the Roger Dubuis watch collection for men is its approach to skeletonisation. Traditional designs use openwork primarily for decoration. However, Roger Dubuis treats skeletonisation as a structural challenge, reimagining bridges, wheels, and plates to balance visual drama with mechanical integrity. This interplay of form and function allows wearers to witness the heartbeat of the watch while showcasing the architectural complexity that lies within.

By combining bold design with mechanical innovation, the Excalibur line blurs the boundary between timekeeping and sculpture. It stands as a modern expression of haute horlogerie. It embodies both Geneva’s centuries-old watchmaking tradition and Roger Dubuis’ vision of “hyper horology,” where engineering and aesthetics coexist seamlessly.

Double (Flying) Tourbillons — pairing for performance

The Roger Dubuis Excalibur Quatuor is one of the most audacious innovations in modern watchmaking and a true milestone for the industry. Despite depending on a single balance wheel or a tourbillon to counteract the effects of gravity, Roger Dubuis developed a movement with four sprung balances working simultaneously. Arranged at 90-degree angles to one another, these balances are connected through an intricate system of differentials that continuously average out their rates. The idea is to neutralise positional errors instantly, rather than waiting for the longer averaging process of a tourbillon.

Each balance in the Quatuor vibrates at 4 Hz, which translates to 28,800 vibrations per hour. With four balances running together, the movement of the Roger Dubuis watch for men generates an astonishing combined frequency of 16 Hz. It is one of the fastest and most mechanically ambitious constructions ever placed in a wristwatch. The result is a level of timekeeping stability that pushes the limits of mechanical precision.

To handle this complexity, Roger Dubuis also turned to innovative materials, such as, silicon and cobalt-chromium, ensuring energy efficiency and durability. The Quatuor stands as a symbol of “hyper horology”. It has merged radical engineering with breathtaking aesthetics and remains one of the rarest technical achievements in contemporary haute horlogerie.

Materials Engineering In Roger Dubuis— Carbon, Cobalt, Titanium, Silicon

One of the most defining aspects of the Excalibur collection is Roger Dubuis’ bold experimentation with advanced materials. 

Silicon

Silicon has become a game-changer in high horology, and Roger Dubuis uses it strategically in certain Quatuor components. Its natural properties, such as, ultra-lightweight, non-magnetic, and highly resistant to wear, make it an ideal material for regulating organs. By reducing friction and eliminating the need for lubrication, silicon components extend the lifespan and reliability of the movement. In Excalibur, silicon allows for higher efficiency and improved precision, especially in complex systems like multi-balance constructions. Also, beyond practicality, its sleek, dark finish adds a modern, high-tech look that perfectly aligns with the brand’s futuristic aesthetic.

Carbon composites

Multi-layered carbon composites and Carbon fibre are used in Excalibur Spider and Quatuor models to achieve remarkable lightness without compromising strength. These cases are built by layering sheets of carbon and compressing them with resin. It results in a material that is durable as well as visually striking, thanks to its marbled texture. Lightweight carbon drastically reduces the watch’s overall mass. It improves wearer comfort despite the often large dimensions of Excalibur models. Moreover, the shock absorption qualities of carbon enhance movement protection. Its futuristic appearance reinforces Roger Dubuis’ “hyper horology” philosophy, merging avant-garde design with advanced material science.

Cobalt-chromium (MicroMelt)

The use of cobalt-chromium alloys, particularly processed with MicroMelt technology, reflects Roger Dubuis’ experimental approach to case construction. MicroMelt allows for a fine distribution of metal particles. It results in a dense, strong, and highly corrosion-resistant material. In Excalibur Quatuor limited editions, this alloy is used to create cases with unique durability and a distinct, luminous sheen that differs from steel or titanium. Cobalt-chromium is also hypoallergenic and maintains its finish exceptionally well over time. Its inclusion in Roger Dubuis watch collection for men is about aesthetics as well as about offering collectors a case material that is rare, robust, and technologically innovative — reinforcing RD’s cutting-edge identity.

Titanium

Titanium has long been prized in watchmaking for its excellent strength-to-weight ratio, and Roger Dubuis leverages it to optimise both performance and wearability. In Excalibur models, titanium is frequently used for tourbillon cages, where reduced mass lowers inertia, improving energy efficiency and enhancing precision. It also provides better shock resistance, crucial for protecting delicate escapements in dynamic wrist movements. When used in cases, titanium makes large, complex Excalibur watches surprisingly light and comfortable. Its resistance to corrosion and hypoallergenic properties further enhance practicality. Finished to Geneva Seal standards, titanium parts balance rugged functionality with luxury-level craftsmanship and aesthetics.

Why these innovations matter — performance vs. theatre

Practical Performance

Behind the dramatic designs, Roger Dubuis’ innovations have genuine technical merit. The twin tourbillons linked by a differential improve rate stability by averaging out errors, while the Quatuor’s four balances address positional variations in real time. Advanced materials like silicon and titanium reduce inertia, enhance energy efficiency, and protect against magnetic fields. These choices aren’t ornamental — they’re deliberate engineering solutions aimed at improving precision, durability, and overall chronometric performance, showing that Excalibur pieces are more than just visual statements.

Horological Theatre

While performance is important, Roger Dubuis thrives on creating visual spectacle. Skeletonised dials reveal the mechanics in motion, oversized cases amplify presence, and star-shaped bridges turn regulators into centre-stage performers. This theatrical approach transforms high watchmaking into an immersive experience — part art, part engineering. For collectors, Excalibur isn’t just a precision instrument but a bold expression of identity. By elevating mechanics into design statements, Roger Dubuis has carved a niche where horology doubles as wearable performance art.

Complications beyond the regulator

Flyback Chronographs

Roger Dubuis integrates flyback chronograph complications into the Excalibur Spider line, powered by in-house calibres such as the RD780. Unlike modular chronographs, these are fully integrated, showcasing the brand’s technical mastery. A column-wheel mechanism ensures smoother pusher action, while the vertical clutch design enhances precision by eliminating hand “jump” when the chronograph is activated. The Roger Dubuis Excalibur Flyback function allows the chronograph to reset and restart with a single press, useful for timing consecutive events. Combined with RD’s signature skeletonised design, these chronographs offer both mechanical efficiency and dramatic visual appeal, reinforcing Excalibur’s identity as “hyper horology.”

Minute Repeaters and Grande Complications

In limited editions of the Excalibur, Roger Dubuis ventures into the realm of minute repeaters and other grande complications. These striking mechanisms in the Roger Dubuis watch for men chime the hours, quarters, and minutes on demand, requiring extraordinary acoustic tuning and case engineering. Roger Dubuis pairs the complexity of repeater mechanisms with its hallmark skeletonisation, turning sound into both a mechanical and aesthetic performance. Some models also combine repeaters with tourbillons or multiple regulators, pushing technical boundaries even further. By merging high complication craftsmanship with bold, architectural design, Excalibur minute repeaters become more than tools for time — they are wearable mechanical symphonies.

High-End Finishing And Geneva Seal In Roger Dubuis Watch

The Poinçon de Genève, or Geneva Seal, is one of the most prestigious certifications in Swiss watchmaking, and many Roger Dubuis Excalibur movements proudly bear this hallmark. Far from being a decorative label, the Seal guarantees that each movement meets strict criteria for craftsmanship, precision, and origin. To qualify, a watch must be manufactured, assembled, and regulated entirely within the Canton of Geneva, ensuring authenticity and heritage.

Equally important are the finishing requirements. Every visible surface — from bridges and screws to wheels and plates — must be hand-decorated with techniques such as anglage (chamfering), Côtes de Genève, and meticulous polishing. Even functional parts that are rarely seen are held to the same standards. Beyond finishing, the Seal also enforces rigorous tolerances and assembly rules to guarantee performance.

By combining radical innovations like skeletonised double tourbillons or the Quatuor with the Geneva Seal, Roger Dubuis demonstrates that its watches are not mere novelties, but true expressions of haute horlogerie.
