Overview
The Roger Dubuis Excalibur MT is an uncompromising expression of contemporary haute horlogerie: dramatic, technically ambitious and created for collectors who want the mechanics to take centre stage. Its openworked architecture reveals the movement in full, while the flying monotourbillon provides the visual and horological focus that defines this exceptional Excalibur model.
Limited to just 88 examples, this watch is number 44 of 88. Roger Dubuis developed the skeleton calibre in Geneva, with each component finished by hand. The result is not simply a transparent dial or decorative movement, but a carefully constructed display of hand craftsmanship, depth and kinetic energy. At £29,950, it occupies a compelling position for collectors seeking a rare Roger Dubuis complication with genuine visual presence.
For collectors building a focused selection of Roger Dubuis watches, the Excalibur MT offers the character for which the brand is known: architectural form, high-level movement finishing and an attitude that refuses to blend into conventional dress-watch design.
Brand and reference history
Roger Dubuis was founded in Geneva in 1995 and quickly established a distinctive identity within modern Swiss watchmaking. Rather than pursuing restrained classicism alone, the manufacture combined traditional finishing and complications with bold cases, expressive skeletonisation and an unmistakable sense of theatricality. The Excalibur collection became the clearest embodiment of that approach, pairing strong, often angular exteriors with movements designed to be seen.
The Excalibur MT belongs to the generation of Roger Dubuis watches in which the skeleton calibre is central to the design rather than an incidental feature. Its openworked construction allows the eye to travel through bridges, wheels and the tourbillon assembly, creating an impression of mechanical depth. The limited edition of 88 pieces reinforces the model’s place within a highly exclusive series, while this particular watch is identified as number 44 of 88.
Roger Dubuis has long appealed to collectors who value rarity alongside technical ambition. In this Excalibur, the brand’s Geneva manufacture combines the traditional disciplines of hand finishing with an unusually expressive presentation. It is a watch for buyers who want their collection to demonstrate individuality as well as horological knowledge.
Dial, hands and design detail
There is no conventional dial to distract from the movement. Instead, the front of the watch is occupied by the openworked calibre, with bridges and structural elements arranged to create a deliberate visual composition. This is skeletonisation with purpose: the architecture is exposed so that the wearer can observe the mechanism’s operation and appreciate the finishing from multiple angles.
The flying monotourbillon is the visual anchor. Its rotating carriage adds movement to the display, while the absence of an upper bridge gives the tourbillon a suspended appearance. This creates the floating effect that makes a flying tourbillon so compelling, particularly when viewed through the openworked front of the watch. The mechanical display changes subtly as the watch is moved, with light catching the bevelled edges, polished surfaces and recessed areas.
Time reading remains integrated into the open architecture rather than imposed upon it. The hands are designed to sit clearly above the exposed mechanics, maintaining practical legibility while preserving the watch’s sculptural character. The overall effect is more akin to a miniature piece of kinetic architecture than a conventional dress watch, with every visible component contributing to the composition.
Case, bracelet and wearability
The Excalibur case has the bold, assertive profile associated with Roger Dubuis. Its form provides a strong frame for the skeleton movement, with a substantial presence that complements the complexity inside. Rather than hiding behind thinness or understatement, the case makes a deliberate statement and gives the watch the wrist presence expected from an Excalibur with a flying tourbillon.
Its design balances polished and contrasting surfaces to emphasise the case geometry. The bezel and lugs work with the openworked display, guiding the eye inward towards the movement. This relationship between exterior and interior is important: the case is not merely a protective shell, but part of the watch’s visual language.
The supplied presentation is completed by a matching bracelet, giving the watch a cohesive and integrated appearance on the wrist. A bracelet can make a highly complicated watch feel more contemporary and substantial than a traditional leather strap, while also reinforcing the Excalibur’s modern character. Buyers should assess the bracelet’s fit and adjustment requirements carefully, particularly if they prefer a close or relaxed wearing position.
Although categorised among dress & classic watches, this Roger Dubuis is not a conventional formal watch. It can complement tailoring, but its strongest appeal is its ability to bring haute horlogerie into a more expressive, contemporary setting. The design is best suited to occasions where individuality and mechanical artistry matter as much as discretion.
Movement and technical specification
At the heart of the Excalibur MT is a Roger Dubuis Geneva-manufactured skeleton calibre incorporating a flying monotourbillon. The tourbillon is designed to counteract certain effects of gravity on the regulating organ by continuously rotating the balance and escapement assembly. In practical terms, it is a sophisticated technical feature; in visual terms, it is the most animated element in the watch.
The movement’s bridges and components are openworked to reduce visual mass and reveal the underlying construction. This requires exceptional precision because the remaining structural elements must retain the strength and stability needed to support the mechanism. Skeletonisation also leaves finishing fully exposed, making the quality of bevelling, polishing, surface treatment and edge definition especially important.
Roger Dubuis states that every component is finished by hand. That commitment is significant because hand finishing is demanding, time-consuming work that cannot be reduced to a single decorative treatment. Edges must be shaped and refined, surfaces prepared consistently and transitions executed with care. On an openworked tourbillon, these details remain visible from the front and contribute directly to the watch’s character.

The Excalibur MT should be regarded as a high-complication mechanical watch requiring appropriate care. Its exposed construction is part of its appeal, but it also means that servicing should be entrusted to a suitably qualified specialist familiar with Roger Dubuis movements and tourbillon calibres.
Sizing and how it wears
The watch has the wrist presence expected of an Excalibur tourbillon. Its impact comes not only from the case dimensions but also from the density of the exposed movement, the architectural case design and the visual activity of the flying tourbillon. On the wrist, it reads as a serious collector’s watch rather than a quiet, conventional dress piece.
The bracelet helps the watch feel purposeful and integrated, while the case design gives it a confident profile beneath a shirt cuff. It is likely to suit collectors who are comfortable with a watch that announces its mechanical content. Those with smaller wrists should consider the case proportions, lug shape and bracelet adjustment together rather than relying on diameter alone; the way a complicated watch wears depends heavily on its curvature and visual balance.
Despite its boldness, the Excalibur MT can be styled with formal clothing because its underlying purpose remains that of an haute horlogerie dress watch. Black tie may call for restraint, but with tailored eveningwear or a sharp suit, the openworked display can become a distinctive point of conversation. For less formal occasions, the bracelet and contemporary case make the watch feel entirely at home.
Collectability and market value
Rarity is a fundamental part of this model’s appeal. With production limited to 88 watches and this example numbered 44 of 88, the Excalibur MT has the scarcity collectors expect from an exclusive Roger Dubuis complication. Limited production alone does not guarantee future performance, but it does create a defined collecting context and makes the individual edition number part of the watch’s identity.
The watch also benefits from a clear technical proposition. A flying monotourbillon, full skeletonisation and extensive hand finishing give it substance beyond brand recognition. It is a piece that can be appreciated for its movement architecture, its craftsmanship and its distinctive design language. These qualities tend to matter to experienced buyers who look beyond conventional dress-watch formats.
At £29,950, this example offers an opportunity to acquire a rare Geneva-made Roger Dubuis tourbillon at a significant level of horological complexity. Market value remains influenced by condition, completeness, servicing history and the strength of the secondary market at the time of purchase. As with any high-complication watch, prospective owners should consider both its collectable appeal and the cost of maintaining it properly.
For comparison and context, collectors may wish to review the dedicated listing for the Roger Dubuis Excalibur MT, while remembering that each individual watch must be assessed on its own condition and supporting details.
Authenticity, condition and servicing
Authenticity is essential when buying a complicated limited-edition watch. The movement, case, edition numbering and finishing should be assessed as a coherent whole, with attention paid to the relationship between the visible calibre and the external case. The stated edition number for this watch is 44 of 88, an important detail for the buyer and for future ownership records.
Condition should be considered in the context of a skeleton tourbillon. Light handling marks may be visible on highly polished surfaces, while the openworked construction makes the overall presentation especially sensitive to dust, fingerprints and inappropriate cleaning. A careful inspection should cover the case, bracelet, clasp, sapphire surfaces and movement, with particular attention to the tourbillon’s operation and the quality of any previous intervention.
Servicing should be planned with realistic expectations. A flying monotourbillon and skeleton calibre contain specialised components and require a watchmaker with appropriate technical competence. A full service may involve inspection, disassembly, cleaning, lubrication, regulation and testing, with the precise scope dependent on the watch’s condition and service history. We recommend discussing servicing requirements before purchase if you are unable to establish when the watch was last maintained.
As no additional provenance, serial number, guarantee or service documentation has been provided for this description, buyers should rely on the details confirmed at the point of sale and on the watch’s own examination. We will present the watch accurately and encourage informed questions before commitment.
