Ultra-Thin 7.8 mm (36 g | US $ 9 999) vs. Sport 16.5 mm (61 g | US $ 899)
1. Why Two Versions?
Richard Mille split the RM 67-02 line into two distinct personalities so wearers can pick exactly the kind of “lightness” they want:
| Version | Measured Thickness* | Measured Weight* | Target User | List Price | Key Selling Point |
|---|---|---|---|---|---|
| Ultra-Thin | 7.8 mm | 36.1 g | Minimal-weight fans, shirt-cuff friendliness | US $ 9 999 | TPT® carbon case + Grade 5 titanium baseplate—practically disappears on the wrist |
| Sport | 16.5 mm | 61.0 g | Outdoor athletes, first-time RM buyers | US $ 899 | Reinforced carbon shell with shock-absorbing spacers; unbeatable value |
* Figures are taken from the digital caliper and 0.1 g precision scale shown in the photos.
2. Real-World Wrist Feel
| Category | Ultra-Thin 7.8 mm | Sport 16.5 mm |
|---|---|---|
| Wearing sensation | 36 g ≈ half a credit card; you forget it’s there | 61 g—still lighter than most steel divers, but feels “present” |
| Visual impact | TPT® carbon stripes look like Damascus steel in profile | Extra girth highlights the signature Grade 5 Ti screws |
| Durability spec | 30 m splash-proof for office & city life | 50 m water-resistant + beefed-up shock protection for skiing, surfing, MTB |
| Psychological price | Squarely in “collector” territory | Sub-$1 k lets you sample RM DNA without anxiety |

5. Bottom Line
RM 67-02 squeezes the same ultra-thin automatic calibre into two extremes of wrist philosophy:
-
Ultra-Thin 7.8 mm – the Formula 1 car of the series: feather-light, technologically intense, and priced accordingly.
-
Sport 16.5 mm – the rally racer: tougher suspension, accessible entry ticket, ready to get dirty.
Either way, Richard Mille proves that light can be tuned for subtlety or for adventure—your wrist, your track.
