The Richard Mille RM 67-01 is the brand's extra-flat automatic: a rectangular-tonneau watch in titanium, powered by the in-house CRMA6 caliber, with hours, minutes and a date. The RM 67-02 is its lighter successor, built from carbon-based composites around the CRMA7 caliber and offered in a series of athlete-linked colorways. Both share the same compact outline, which is why they are the usual answer when a buyer wants a Richard Mille that slides under a shirt cuff. This guide compares them, explains what makes the case and movement different, and covers who each one suits. Bizak & Co. is a sourcing desk, so every watch mentioned here is found to order and none is held in stock.

What is the Richard Mille RM 67-01?
The RM 67-01 is the first Richard Mille in the RM 67 family, a slim automatic launched in titanium in the mid-2010s. Reviews of the original describe a case of roughly 38.7 mm by 47.5 mm and about 7.75 mm thick, which is thin by the standards of a brand known for chunky sports cases. Inside sits the CRMA6 automatic caliber, developed in-house at Richard Mille's base in Les Breuleux, in the Swiss Jura, and fitted with a platinum rotor. The display is simple: hours, minutes and a date window, plus a function indicator near the crown. Titanium editions were followed by gold and diamond-set versions, so check the metal when you compare listings.
What is the Richard Mille RM 67-02?
The RM 67-02 is the second generation of the extra-flat idea, built from carbon-based composites rather than titanium. Launch coverage describes a case of the same 38.7 mm by 47.52 mm footprint and about 7.8 mm in height, weighing around 32 grams with its strap, which made it one of the lightest automatics the brand had produced at the time. The movement is the CRMA7, Richard Mille's seventh in-house caliber, with a skeletonized titanium baseplate and bridges and an open-worked carbon rotor. The RM 67-02 debuted in 2017 in two athlete editions, for the sprinter Wayde van Niekerk and the high jumper Mutaz Essa Barshim. In 2018, four more colorways followed for the tennis player Alexander Zverev, the ski racer Alexis Pinturault, the rally driver Sébastien Ogier and the Formula 1 driver Fernando Alonso. Later editions have used other color schemes and case constructions, so the reference number alone does not tell you which version you are looking at.
RM 67-01 vs RM 67-02: how do they differ?
The simplest difference is material and movement: the 67-01 is titanium with the CRMA6, while the 67-02 is carbon composite with the CRMA7. The outline is nearly identical, so the two sit on the wrist in a similar way, but the 67-02 is lighter and far more colorful. The table below lists the differences that published sources agree on.
| Feature | RM 67-01 | RM 67-02 |
|---|---|---|
| Typical case material | Titanium (gold and diamond-set variants also exist) | Carbon TPT, with quartz TPT bands on some editions |
| Case size | About 38.7 x 47.5 mm | About 38.7 x 47.5 mm |
| Case height | About 7.75 mm | About 7.8 mm |
| Caliber | CRMA6, automatic | CRMA7, automatic |
| Rotor | Platinum | Open-worked carbon composite with a white gold rim |
| Display | Hours, minutes, date | Hours, minutes, date |
| Character | Understated, tool-metal look | Light, colorful, sport-led |
Why is the RM 67 called extra flat?
It is called extra flat because the movement and case are designed to stay far slimmer than most Richard Mille watches. The CRMA6 is reported at about 3.6 mm thick, and the whole watch sits near 7.8 mm, compared with the double-digit case heights typical of the brand's sports references. Flatness is relative, though: it is slim for Richard Mille, not slim like a dress watch from another house. Its true advantage is that the case does not catch on a sleeve.
How does the RM 67 wear on the wrist?
It wears comfortably for most wrists because the case is narrow, light and curved to follow the arm. The 38.7 mm width is modest, while the 47.5 mm length gives the watch presence without extra thickness. The 67-02 feels almost weightless on its elastic strap, and the 67-01 feels slightly more solid in titanium.
Who is the RM 67 for?
The RM 67-01 suits a collector who wants a first Richard Mille that behaves like a dress-sport watch, while the RM 67-02 suits someone who wants color and low weight. Choose the 67-01 if you prefer a quiet titanium look that works with tailoring. Choose the 67-02 if you want the athlete-edition character, such as the Alexander Zverev RM 67-02 or the Alexis Pinturault RM 67-02.

What should you check before buying an RM 67?
- The exact version. Confirm the reference, case material and edition, since the RM 67 family spans titanium, gold, diamond-set and several carbon editions.
- The caliber. A 67-01 should carry the CRMA6 and a 67-02 the CRMA7.
- Box, papers and service history. Complete sets matter at this level; see our box and papers guide.
- Authentication. Use a checklist such as our guide to authenticating a luxury watch, and read our authenticity page.
