Description
APSF Richard Mille RM 055 Carbon “Bubba Watson” Edition
A technically proficient composite replica characterized by accurate 49.90mm case geometry and a customized skeletonized manual caliber.
Powered by Clone RMUL2 Manual Caliber
The mechanical foundation of this APS Factory RM 055 is a highly customized clone of the RMUL2 manual-winding movement. To replicate the extreme skeletonization of the genuine article, APSF has engineered a base movement housed within an intricate web of alloy bridges, mimicking the original grade 5 titanium baseplate. The balance wheel is prominently displayed at the 6 o’clock position, oscillating actively to provide the necessary kinetic visual effect that RM collectors expect. While it lacks the fully free-sprung architecture of the genuine piece, the regulation system is robust and provides reliable daily performance.
Regulated prior to dispatch, this modified manual caliber typically operates within a tolerance of ±10–15 seconds per day, a standard and acceptable variance for highly modified skeletonized replica movements.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, and central seconds with visible balance assembly
- ✅ Winding Direction: Manual winding (Crown)
Technical Specifications
The tonneau case measures precisely 49.90 x 42.70 mm with a 13.5 mm thickness. The forged carbon layering accurately simulates the matte, striated appearance of genuine NTPT carbon, secured by accurate star-shaped spline screws.
Features a deeply recessed rehaut with painted indices and subtle dark green accents. The hands are correctly proportioned and finished with luminescent material for low-light visibility.
Constructed from the same forged carbon block as the case, ensuring the striated patterns flow naturally. The bezel is precisely torqued down against the mid-case gasket.
A hybrid strap featuring a white nylon exterior bonded to a natural rubber base for sweat resistance. Secured by a lightweight, spring-loaded titanium-style folding clasp.
Why APSF for This Reference?
Many collectors ask: “Why not ZF Factory?”
While ZF produces an excellent RM055, the APS Factory edition is frequently favored for its superior movement bridge finishing and more reliable manual-winding mainspring barrel. Furthermore, the carbon striations on the APSF case exhibit a slightly more authentic matte texture under natural lighting, avoiding the overly glossy resin look found on lower-tier replicas.
Full Disclosure: While the RMUL2 clone is visually striking, several of the visible gear train components are decorative plates rather than functional wheels, a necessary compromise in current RM replica movements.

Collector Q&A
Q: Is the movement a real tourbillon as the title suggests?
A: No. The genuine RM 055 utilizes a skeletonized RMUL2 manual-winding movement, not a tourbillon. This APSF replica accurately follows that architecture with a visible, oscillating balance wheel at 6 o’clock that mimics the genuine free-sprung balance aesthetic, but it is not a true tourbillon complication.
Q: How accurate is the carbon pattern compared to the genuine NTPT carbon?
A: APS Factory uses a highly refined forged carbon process that closely replicates the genuine NTPT (North Thin Ply Technology) aesthetic. It achieves the correct matte finish and striated layering, though under macroscopic inspection, the carbon layers are marginally thicker than those produced by Richard Mille’s proprietary machinery.
Q: Are the case dimensions strictly 1:1 with the original RM 055?
A: Yes, dimensional accuracy is a major strength of this APSF release. The case measures precisely 49.90 by 42.70 millimeters with a thickness of 13.5 mm, successfully mirroring the exact footprint and wrist presence of the authentic piece.
Q: What is the primary known flaw with this APSF RM 055 movement?
A: While the RMUL2 clone movement is visually impressive and highly skeletonized, several of the gears visible through the dial and caseback are decorative plates rather than functional components of the active gear train. This is a common and necessary limitation in current Richard Mille replica movements to maintain structural stability.
