In the high-end replica circle, Richard Mille has always been synonymous with “technical flow” and “rich standard equipment”. In 2025, the ZF factory took action again and launched a work that players will call “King of Bombs”——RM-055 “All Gray” Bubba Watson Special Edition Replica Watch. This time, they not only reproduced the appearance, but also moved the “hardcore genes” of the original work into the civilian price range.
The first thing that catches the eye is its visual language of high-grade matte gray throughout. The case size is49.90×42.70mm, although it has a large diameter, it is not an exaggerated pile of materials, but accurately restores the original “sports supercar”-like presence. What’s really great is the material——Micro-sandblasted titanium carbide (TiC). This is not an ordinary coating. Instead, grade 5 titanium metal is precision sandblasted with glass beads in a low-pressure environment to form a uniform, delicate, non-reflective but textured “full gray” surface. What’s even more hard-core is that its Vickers hardness is as high as1450, far exceeding that of stainless steel (200–300) or even ceramics (about 1,000). There is almost no fear of scratches in daily wear, and it is truly “like new after three years of wearing”.
The case lines are also very sculptural: stepped side edges, sharp chamfers, and naturally transitioning lugs not only retain the iconic “skeleton structure” of the RM series, but are also finely polished to ensure comfortable wearing. Despite its size, it fits surprisingly well after you use it. This is due to ZF’s in-depth polishing of ergonomics.
The movement part is even more surprising. ZF is equipped with a new self-developedCaliber RMUL2 integrated manual winding movement——Note that it is an “one-piece movement”, that is, all parts from the base plate to the gears are molded independently and are not spliced together. The main body of the movement adoptsGrade 5 titanium alloy, matchPVD coating + Titalyt surface treatment, showing a low-key contrast between dark gold and gray. Looking through the hollow dial, it looks like a miniature F1 engine roaring on the wrist.
Functionally sincere:Two-way efficient winding、Adjustable barrelImprove power output stability,Double barrel series designExtended energy storage and optimized torque release, also equipped withProfessional grade anti-shock system. After wearing it continuously for a week, the average daily error was stable within **±5 seconds**, and the walking time was still reliable after strenuous exercise. What’s even more interesting is that when you are close to your ears, you can hear the clear and rhythmic “gear bite sound”, which is the mechanical rhythm of high-precision movements.
As a special version of RM-055, this “all gray” Bubba Watson model pays tribute to the golf star Bubba Watson. Its minimalist and redundant design language also fits the pursuit of “low-key violent aesthetics” by modern players.
In summary, the RM-055 replica launched by ZF factory has already surpassed the category of “imitation watch”. it usesReal materials + hard core movement + ultimate details, allowing ordinary players to experience Richard Mille’s iconic “material technology + mechanical art” at one-tenth or even lower cost. If you are tired of Rolex and Omega on the street and long for a piece of wrist art that can truly show your personality and taste, then this “all gray” RM-055 may be the most worthy niche masterpiece in 2025.
