UmiF Richard Mille RM 67-02 “Mutaz Barshim” Red Carbon
By achieving a verified 8.4mm thickness and 36.6g mass, UmiF sets the current benchmark for ultra-flat Richard Mille replication.
Powered by Modified CRMA7 Clone
The engine inside this RM 67-02 is a specialized Asian automatic caliber, heavily modified to clear the stringent thickness constraints of the 8.4mm case. To address the visual complexity of the genuine CRMA7, UmiF engineered an independent animated gear train visible at the 7 o’clock position. While mechanically distinct from the genuine escapement, this kinetic module successfully replicates the dynamic dial motion that defines the Richard Mille aesthetic. The skeletonized bridges are finished with micro-blasting and precise beveling to mimic titanium architecture.
⏱ Accuracy Profile:
Factory rated at ±10–15 seconds per day. The movement relies on a standard regulating organ, ensuring stable timing under normal wear despite the extensive aesthetic modifications.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, and kinetic animated lower gear
- ✅ Winding Direction: Bidirectional automatic winding
Technical Specifications
THE BUILDRed NTPT Carbon
Machined from layered carbon composite, the case achieves a verified 8.4mm thickness and a total watch weight of just 36.6 grams, offering unparalleled wearing comfort.
THE DIALSkeletonized Baseplate
Features deep emerald green dial accents and white hand-painted markers. The skeletonization depth is carefully calibrated to hide the base movement while highlighting the custom bridges.
THE BEZELLayered Carbon Fiber
The signature spline screws secure the red and white carbon layers. The damascene pattern is randomized during the machining process, ensuring no two cases are exactly alike.
THE BRACELETErgonomic Elastic Nylon
A seamless white nylon strap that utilizes natural elasticity rather than a folding clasp, reducing overall weight and eliminating bulky hardware beneath the wrist.
Why UmiF for This Reference?
Many collectors ask: “Why not ZF or KVF?”
While other factories produce excellent standard Richard Mille cases, their extra-flat variants frequently exceed 10.5mm to accommodate off-the-shelf movements. UmiF prioritized dimensional accuracy, engineering a custom movement base plate to achieve an 8.4mm profile. This 2mm reduction drastically alters the watch’s center of gravity, allowing it to wear precisely like the genuine ultra-thin RM 67-02.
Full Disclosure: The animated lower-left gear provides excellent visual kinetic energy but does not replicate the true functional architecture of the genuine CRMA7 going train. Additionally, the white nylon strap will naturally attract dirt with heavy daily use.

Collector Q&A
Q: Why is this model sometimes labeled as a ‘Tourbillon’?
A: The genuine RM 67-02 utilizes the automatic CRMA7 caliber, not a tourbillon. The replica market nomenclature often incorrectly applies the ‘tourbillon’ tag to any skeletonized RM with an exposed rotating gear. This UmiF model correctly functions as an automatic watch with a kinetic animated gear, strictly adhering to the genuine’s automatic architecture.
Q: How does the 36.6g weight compare to the genuine Mutaz Barshim edition?
A: The genuine RM 67-02 weighs approximately 32 grams including the strap. At an independently verified 36.6 grams, the UmiF version is remarkably close, utilizing lightweight layered NTPT carbon and a specialized movement baseplate to achieve a mass that feels virtually identical on the wrist.
Q: Is the white elastic nylon strap adjustable for different wrist sizes?
A: Like the genuine, the elastic nylon strap relies on inherent fabric stretch rather than a traditional folding clasp or buckle. It comfortably accommodates average wrists between 16cm and 18.5cm, but cannot be mechanically micro-adjusted beyond its natural elasticity.
Q: What are the known limitations of the modified CRMA7 clone movement?
A: While UmiF achieved an impressive 8.4mm case thickness, the custom animated gear mechanism introduces slight mechanical rotor noise during rigorous wrist movement. Additionally, the power reserve is limited to approximately 36 hours, which falls short of the genuine caliber’s 50-hour capacity.
