Is your RM 67
the real deal?
The Richard Mille RM 67-01 Automatic Extra Flat is one of the brand's most wearable models, designed as an everyday ultra-thin luxury sports watch. At just 7.75mm thick, it's remarkably slim for a Richard Mille. Its relatively "accessible" position in the RM lineup (though still six figures) makes it one of the most commonly counterfeited Richard Mille references.
How to authenticate an RM 67
Tonneau Case Shape & Carbon TPT/Titanium Finish
The RM 67 features Richard Mille's signature tonneau (barrel) case shape. Depending on the variant, the case is made from grade 5 titanium or Carbon TPT. Titanium versions should have a precise satin-brushed finish, while Carbon TPT displays a distinctive layered pattern unique to each watch. Counterfeits often have incorrect case proportions, wrong material texture, or a Carbon TPT pattern that looks printed rather than genuinely layered.
Skeletonized Dial With Hour Markers
The RM 67 dial is partially skeletonized, revealing parts of the CRMA6 movement beneath. The hour markers are applied and filled with luminous material. Each marker should be precisely positioned and uniformly finished. The skeletonized sections should reveal genuine movement components with proper finishing. Counterfeits often have poorly cut dial openings, misaligned markers, or a fake movement visible through the skeleton cutouts.
Crown With RM Logo
The crown features the "RM" logo engraved on its face. It should be made from the same material as the case (titanium or matching metal) and operate with smooth, precise action. The crown guards should integrate seamlessly with the case. Counterfeits often have a poorly engraved or stamped logo, a crown made from the wrong material, or crown guards that don't fit flush with the case.
Case Back With Visible Movement (CRMA6)
The transparent case back reveals the CRMA6 automatic movement. The movement should display proper Richard Mille finishing including micro-blasted surfaces, beveled edges, and the signature skeletonized rotor. All text engravings on the movement should be laser-etched with perfect precision. Counterfeits use generic movements that lack the correct architecture, finishing quality, and RM-specific rotor design.
Case Screws (Grade 5 Titanium, Spline Drive)
The RM 67 uses grade 5 titanium spline-drive screws to secure the case back and bezel. These screws have a distinctive multi-point star pattern (not Phillips or flathead) and should sit perfectly flush with the case surface. Each screw should be identically finished. Counterfeits commonly use Phillips-head or hex screws, or have spline-drive imitations that are poorly machined with inconsistent depth.
Overall Weight & Material Feel
The RM 67 in titanium weighs approximately 32 grams (without strap), making it exceptionally light for its size. The titanium should have a cool, smooth feel with precise edges. Carbon TPT versions are even lighter with a distinctive texture. Counterfeits are often heavier due to the use of steel or alloy, and lack the precise tactile quality of genuine Richard Mille finishing.
RM 67 counterfeit warning signs
Wrong Case Material or Finishing Texture
Genuine RM 67 cases are made from grade 5 titanium or Carbon TPT, each with a distinctive look and feel. If the case appears to be stainless steel (heavier, more reflective), or if Carbon TPT patterns look uniform and printed rather than organically layered, the watch is counterfeit.
Movement That Doesn't Match CRMA6 Architecture
The CRMA6 has a specific bridge layout, skeletonized rotor design, and finishing style that is immediately recognizable to experienced collectors. If the visible movement has a different bridge configuration, uses a standard rotor, or lacks the micro-blasted and beveled finishing, it is not a genuine Richard Mille movement.
Incorrect Case Thickness (Should Be ~7.75mm)
The RM 67's defining characteristic is its slim 7.75mm profile. Counterfeits frequently cannot achieve this thinness because they use thicker generic movements, resulting in a case that is noticeably thicker. Even a few millimeters of extra thickness changes the entire look and feel of the watch on the wrist.
Screws That Are Phillips Head Instead of Spline Drive
Richard Mille exclusively uses spline-drive screws (multi-point star pattern) made from grade 5 titanium. If any screws on the watch are Phillips head, flathead, or hex drive, the watch is definitively counterfeit. This is one of the simplest and most reliable authentication checks for any Richard Mille.

Frequently asked questions
What movement does the Richard Mille RM 67 use?
The RM 67-01 uses the CRMA6 automatic movement, a skeletonized caliber designed and manufactured in-house by Richard Mille. It features hours, minutes, seconds, and date complications, with approximately 50 hours of power reserve. The movement is notable for its extreme thinness at just 3.6mm, which allows the overall watch to achieve its slim 7.75mm profile.
Why is the RM 67 called "Extra Flat"?
The RM 67-01 is called "Extra Flat" because at just 7.75mm thick, it is one of the thinnest watches in the Richard Mille lineup. Most Richard Mille models are known for their substantial case depth (often 15-20mm), so the RM 67's slim profile is remarkable for the brand. This thinness is achieved through the ultra-thin CRMA6 movement (3.6mm) and careful case engineering.
How much does a Richard Mille RM 67 retail for?
The Richard Mille RM 67-01 retails for approximately $100,000 to $150,000 depending on the material and configuration. The titanium version sits at the lower end, while Carbon TPT and other exotic material variants command higher prices. Limited editions and discontinued configurations can trade significantly above retail on the secondary market.
