Description
Richard Mille RM 055 Baby Bubba All Grey Boutique Edition Super Clone, Grade 2 titanium matte cool grey treated with titanium coating process Bezel, Grey sandblasted Flange, John Studio Custom Edition Replica Watch.
Bubba Watson and RM 055 Baby Bubba
Bubba Watson, the renowned American PGA professional golfer, is a towering talent known for his explosive swing speed and immense power. Historically, golfers avoided wearing mechanical watches because the intense G-forces generated during a swing could instantly shatter the hairsprings and pivots of standard mechanical movements. Richard Mille proved its capabilities with the 2011 launch of the first-generation Bubba Watson model: the RM 038 Tourbillon.
While the RM 038 made a spectacular debut, its tourbillon movement was produced in very limited quantities and carried a steep price tag; consequently, the RM 055 series was introduced in 2012. This model dispensed with the tourbillon in favor of the RMUL2—a manual-winding, fully skeletonized movement engineered specifically for the rigors of competitive sports. Lighter and more rugged than its tourbillon predecessor while retaining the DNA of the RM 038, it earned the affectionate nickname "Baby Bubba."

The RM 055 Super Clone Development History
• 2014–2021: The Miyota Spacer Flaw & Mock Plates: Early iterations across the entire RM 055 line used automatic Miyota 9015 or Seagull movements hidden under static, non-functional decorative plates. To secure the undersized movement, a massive black plastic spacer ring choked the interior perimeter, completely blocking the signature translucent look. The bulky profile exceeded 15.5mm in thickness.
• 2022–2023: The Bespoke Studio Breakthrough: Independent boutique engineers hand-carved the first 1:1 functional manual-wind skeletonized clone movement. Single calibers commanded underground black-market prices upwards of $2,500 USD. This breakthrough permanently deleted the notorious plastic spacer flaw, allowing every gear to turn realistically and restoring true mechanical transparency.
• 2024–2026: The Tier-1 Factory Mass Production Storm: Industrial giants (APSF, ZF, BBR) mass-produce the RMUL2 integrated movement, manufactured in Dandong using industrialized, custom-made materials. To replicate the luxurious materials, the factory employs high-fidelity alternatives: for example, using high-density fine industrial ceramics to create a monochrome look, or using a titanium coating process to achieve an "all-grey" invisible aesthetic. Standard case specifications compress the thickness to below 13.5 mm (approximately 75 grams), but general tolerances and minor font/bridge alignment defects still exist on the large-scale assembly line.
• 2025–2026: The Pinnacle: Custom Studio Modified CBUs: The absolute apex today. High-end private custom modification studios (e.g., Boss Studios, John Studio, RCF) deconstruct mass-factory flaws for 100% aesthetic alignment across all material versions. Utilizing hand-finished, Bespoke Vaucher-based clone movements, master watchmakers perform extreme micro-corrections—such as rectifying the inner shadow font printing (e.g., the short center stroke of 'E')—and re-assemble the chassis with zero footprint to deliver unique serialized masterpieces.
Craftsmanship: Genuine vs Super-Clone
Genuine Product
The bezel is made of TiC (titanium carbide), an extremely hard composite material with a deep gray matte metallic finish. The middle layer and case back are made of grade 5 titanium, with grade 5 titanium spline screws, all treated with a sandblasting process. The entire case is predominantly gray. It houses the RMUL2 manual-winding skeletonized movement with a double mainspring barrel system, offering a power reserve of 55 hours.
This Top-Tier Replica
1, The bezel is crafted from Grade 2 titanium and treated with a special titanium coating process, resulting in a matte, cool gray color with a subtle metallic sheen, mimicking the color of TiC titanium carbide. The 45-degree beveled edges are hand-cut and polished using high-end diamond tools, creating a smooth and soft texture. The middle layer and case back are also made of Grade 2 titanium and are formed in one piece by CNC machining. The side curvature and concave lines are perfectly replicated. The surface uses the same low-pressure sandblasting process as the genuine product, treated with micro-glass beads, giving it a delicate and smooth feel.
2, The all-grey flange demands exceptional color matching skills. It features a one-piece molded Grade 2 titanium inner flange, its surface repeatedly polished and color-matched to achieve near-zero color difference between its hue and the outer titanium carbide bezel. The letters and minute markers on the bezel are transferred layer by layer using vacuum silicone pad technology. The lettering is clear and prominent; even under magnification, the white lettering and minute marker edges are free of burrs, ghosting, or color bleeding. The twelve-hour markers are pre-drilled with CNC micro-drills and hand-filled with Super-LumiNova® luminous material using an ultra-fine pen tip. In sunlight, these dots appear pure white and do not emit light; in darkness, they emit a faint ice-blue glow, perfectly replicating the details of the original watch.
3, Unlike other versions, the lettering on the back cover of this Super Clone RM 055 All Grey is laser-cut and then hand-filled with industrial-grade paint. The thickness, spacing, and depth of the lettering are virtually identical to the genuine product, and there is no overflow at the edges of the lettering.
4, The movement was developed through reverse engineering based on the gear structure schematics of the original RMUL2 caliber. The layout of the main gear train has been optimized; the black skeletonized structure is not merely decorative—it serves as the actual baseplate supporting the gear assembly. The barrel at the 11 o'clock position and the balance wheel at the 8 o'clock position are fully functional, with the movement of the hands driven by a gear train integrated directly into the skeletonized structure. However, as this is a clone, the power reserve is 40 hours, compared to the 55 hours of the genuine version.
Low-end Replica
The entire case is crafted from 316L stainless steel, with the bezel electroplated to a gray finish, lacking the matte metallic look and the texture of titanium carbide. The 45-degree edge polishing is machine-machined, without any hand-polishing. The sandblasting on the middle layer and case back feels cheap, with an overly coarse texture, like sandpaper. Because the entire case is made of 316L steel and the movement is not a true skeletonized thin-layer design, the watch typically weighs over 120g and is over 15mm thick.
Balance Wheel
The entire RM 055 "Baby Bubba" series omits the tourbillon mechanism; instead, it positions the balance wheel at the 7 o'clock mark. While the balance wheel physically oscillates back and forth, its extremely high oscillation frequency—combined with the skeletonized design—creates an optical illusion that makes it appear to be spinning continuously in a single direction. Consequently, it is laughable that many replica websites falsely advertise their RM 055 models as having a tourbillon.
• Extremely High Oscillation Frequency: The watch operates at a rapid 4 Hz (28,800 vibrations per hour), meaning the balance wheel completes eight high-speed back-and-forth oscillations every second (four to the left and four to the right).
• Persistence of Vision: The human eye cannot track eight directional changes per second. Furthermore, the balance wheel is a nearly perfect circle featuring only four tiny adjustment weights, lacking prominent elongated arms or large reflective surfaces. During rapid oscillation, the afterimages of the ring's edges overlap on the retina, creating the visual illusion of a spinning top rotating at high speed in a single direction.
How does the super clone version replicate the balance wheel?
• This RM 055 all grey super clone features a genuine integrated skeletonized movement, reverse-engineered from the gear schematics of the authentic RMUL2 caliber. The layout of the main gear train was modified to relocate the timekeeping balance wheel to the 7 o'clock position, achieving a fully transparent, unobstructed "floating" effect.
• Visual Replication of the Weighted Balance Wheel: The authentic RM 055 utilizes a free-sprung balance system, featuring four rotatable adjustment weights on the balance wheel ring. To replicate the exact light reflections and visual details seen during high-speed rotation (creating a "motion blur" effect), this super-clone RM 055 features a custom-made circular balance wheel equipped with four micro-weights. When the watch is running, the dynamic blur of the ring and the way the screws catch the light are virtually indistinguishable from the genuine article to the naked eye.
How do I spot the difference?
• Although the visual fidelity exceeds 95%, technical flaws remain visible under strong light or macro photography. The genuine model utilizes a true free-sprung balance system; rate adjustment is achieved solely by rotating the four weights on the balance wheel. Consequently, above the balance wheel (positioned at 7 o'clock) and near the hairspring's anchor point, there is only a single fixed stud securing the outer end of the hairspring—there is absolutely no secondary metal regulator lever.
• While this top-tier clone successfully replicates the appearance of the weighted balance wheel, its underlying movement regulation mechanism remains traditional. If you shine a bright light or use a magnifying glass to examine the area deep near the balance wheel's axis (at the 7 o'clock position), you will spot a protruding micro-metal lever with one or two prongs—this is the regulator arm (or "fast-slow" lever) used to adjust the hairspring's effective length. Although John Studio has gone to great lengths to disguise this component within the shadows using a black coating, the physical presence of this "extra metal lever" is an inherent mechanical necessity that cannot be eliminated.
John Studio has corrected the color of the shock-absorber jewel
On the genuine RM 055, the Incabloc shock-absorption system at the center of the balance wheel pivot houses a custom-made, completely colorless and transparent synthetic jewel bearing; this design choice preserves the movement's stark, high-tech aesthetic characterized by black and grey tones. In contrast, most high-end factories producing clone movements still rely on standard, off-the-shelf shock absorbers, where the central bearing retains the characteristic purplish-red hue of traditional synthetic rubies. Against the backdrop of a fully skeletonized, pitch-black movement, that "pink dot" at the 7 o'clock pivot is a glaring giveaway that instantly reveals the watch as a replica. Driven by a commitment to achieving visual alignment down to the micron level, John Studio has completely redesigned the central shock-absorber jewel to match the genuine article—using a colorless, transparent "white" jewel.
Daily Care Guide
1, Avoid strenuous activity: The Calibre RMUL2 movement in the authentic RM 055 is specifically engineered to withstand the immense centrifugal forces and impacts generated by a professional golfer's swing, capable of resisting extreme external shocks exceeding 5,000 Gs. In contrast, the movement in this RM 055 all grey super clone was developed via reverse engineering based on the gear layout schematics of the original RMUL2; while its layout has been modified and it visually mimics the four shock-absorbing rubber mounts, the internal movement is actually rigidly fixed to the case via a traditional metal movement holder. Consequently, in the event of violent vibration, 100% of the impact force is transmitted directly to the movement, potentially causing component displacement or damage. Therefore, one should avoid extremely strenuous activities while wearing it; its intended role is that of a "visual substitute for social settings."
2, Do not submerge in water: Although the nominal water resistance is 10 meters, in reality, this RM 055 all grey super clone watch can only withstand everyday splashes and sweat. Do not wear it while swimming, showering, or in contact with warm water. Of course, the genuine RM watch also has very limited water resistance, because achieving a perfect seal on its tonneau-shaped, irregular curved surface is extremely difficult. Furthermore, the multi-piece sandwich structure requires more than 20 titanium spline screws to secure the various components, meaning that gaps and potential leak points are multiplied.
