Many customers ask: “Why does this ultra-thin model cost so much more?”
Here’s the honest answer.
Richard Mille Ultra-Thin Models Are Among the Hardest to Replicate
Richard Mille watches are already considered one of the most difficult series to clone in the entire replica industry. The RM 67-01 and RM 67-02 take that challenge to another level because they belong to RM’s famous ultra-thin collection.
Ultra-Thin Construction (Only 7.75mm – 7.8mm thick)
The genuine RM 67 series measures just 7.75mm in total thickness. Replicating this extreme slimness requires a specially engineered ultra-thin movement, precision case machining, and perfect internal clearance. Even a 0.5mm error ruins the watch.
Titanium Case + Full Skeleton Design
These models use lightweight Grade 5 Titanium with full skeletonized architecture. Every bridge, screw, and gear must be perfectly finished and visible — dramatically increasing production complexity and cost.
Complex Movement Engineering
High-end versions feature a real rotating escapement wheel at 7 o’clock and a functional automatic rotor, all within an ultra-thin structure.
Top Factories Making RM 67-01 & RM 67-02 (2026 Update)
Currently, only a few factories can produce acceptable ultra-thin RM67 versions:
UMI Factory (ZF sub-factory) — Currently the hottest and best version, especially the RM 67-02 V10. UMI excels at true 7.8mm thickness, live rotating escapement wheel, excellent titanium feel, and overall finishing.
AV Factory — Known for being the lightest (around 35g).
ZF Factory — Stable and reliable but usually slightly thicker.
UMI is widely regarded as the best RM 67-02 available right now, priced around $5,500. It offers the best balance of slimness, detail, and wearability.
Note: The RM 67-01 is generally harder to perfect than the 67-02. The version shown below is one of the best current versions on the market (though not UMI), and commands a premium price due to its superior execution.

7 O’Clock Live Rotating Escapement Wheel
One of the most impressive features of the UMI version is the fully functional rotating escapement wheel at 7 o’clock — clearly visible and operating in real time.
Ultra-Thin Case Thickness Verification
We are proud to present the actual thickness measurement of our top versions:
Both models have successfully replicated the original Richard Mille ultra-thin profile. Achieving this level of accuracy in such a complex skeletonized design is extremely difficult and is exactly why these pieces are significantly more expensive than standard replicas.
Original Prices Justify the Investment
Genuine RM 67-01 and 67-02 regularly sell for $200,000 – $350,000+. When the original is this expensive, only top factories like UMI are willing to invest the huge R&D and tooling costs needed for a convincing super clone.
What You’re Actually Paying For
- Accurate 7.75–7.8mm ultra-thin profile
- Correct titanium weight and wrist-hugging curvature
- Multi-layer skeleton depth and finishing
- Functional 7 o’clock rotating wheel (UMI)
- Premium materials and long-term reliability
- These details separate a true super clone from regular replicas.
Final Thoughts
Yes, the RM 67-01 and RM 67-02 super clones are expensive — but you’re getting one of the most technically advanced Richard Mille replicas ever made. If you want the closest experience to the real ultra-thin RM without the six-figure price, UMI RM 67-02 is currently the top choice.
