Bokey TimeHello everyone, this is Boji Watch Industry. Today’s watch review features the Roger Dubuis single flying tourbillon watch from BBR Factory, with the official model: Roger Dubuis Excalibur RDDBEX0838. This is currently the highest version available on the market. Below, Boji will briefly introduce the details and shortcomings of this BBR Factory Roger Dubuis 0838 tourbillon.
Roger Dubuis: Based on the artisanal complexity of traditional watchmaking, it seeks to present more innovative ways of appreciating haute horology through contemporary aesthetics, while using modern watchmaking techniques to further enhance the performance and usability of mechanical watches. In this way, “Hyper Horology” should be a timepiece that combines aesthetic appreciation with superior wearing performance.
Roger Dubuis’ RD0838 Single Flying Tourbillon wristwatch challenges the design from flat fixed to three-dimensional fixed movement. The shape of the bridges and plates must be recreated with the same rigor as architectural structure research—they must possess aesthetic appeal while embodying the characteristics of haute horology craftsmanship. All fixed axes and positions need to be redesigned, yet the goal is not merely to create a three-dimensional form at the expense of increased movement thickness. This is a highly meticulous and cautious design process, involving constant comparison and construction of every detail, inside and out, to achieve a movement structure that stuns with the naked eye.
The above is the official introduction from Roger Dubuis. Returning to today’s topic, the BBR Factory 0838 replica watch has a diameter of 42mm. The dial design features a deep blue primary color scheme with double-line styling. These meticulously designed lines extend downward, approaching infinitely but never intersecting, creating a strong visual contrast. The case is made of 316L stainless steel. Additionally, there are models available in dark gray DLC-coated titanium and EON GOLD rose gold—each with distinct characteristics. A unique star-shaped decoration floats above the barrel, while the openworked single flying tourbillon at 7 o’clock direction fully showcases Roger Dubuis’ exceptional watchmaking craftsmanship.

The double-folded dial edge is combined with a transferred minute track and brand logo text, embedding the brand’s identity into the design.

The flaw in appearance lies in the presence of a hairspring stud on the tourbillon device at the 7 o’clock position. The original model uses a free-sprung balance with only one stud, while the BBR factory version has two—a key difference between a ¥1+ million authentic watch and a ¥5,000 replica. Despite this, all other gears in the movement match the original. Whether adjusting the time or winding the watch, you can observe the meshing and operation of the gears, showcasing a strong mechanical aesthetic.
The caseback features a transparent design, allowing a clear view of the movement’s operational beauty. The RD512SQ single flying tourbillon movement, subjected to sandblasting and calibration, boasts a distinct shape with smooth lines. This movement, including the internal tourbillon, uses new anti-magnetic materials, effectively enhancing the watch’s service life (the BBR factory model is equipped with a customized Seagull tourbillon movement). Additionally, the lightweight design optimizes the movement’s performance, with power reserve significantly increased to 72 hours—even if unworn over the weekend, no need to reset the time on Monday. The BBR Factory Roger Dubuis single flying tourbillon watch achieves full replica accuracy in strap design: it features an expandable strap design. While the case diameter is 42mm, it truly fits wrists 18cm or larger; those with smaller wrists (15–17cm) will likely find it ill-fitting. Unfortunately, it lacks a quick-release mechanism, which is a notable drawback. Overall, the BBR Factory Roger Dubuis Excalibur RDDBEX0838 tourbillon replica offers remarkable authenticity. While satisfying one’s desire for a mechanical watch with a ¥1.25 million authentic model is impractical for most, BBR’s release—with 95% replication accuracy—allows horology enthusiasts to indulge in the beauty of mechanical craftsmanship without the premium price tag.
