Introduction

When you hear “Richard Mille,” you probably think of tonneau-shaped behemoths that cost more than a supercar and weigh about as much. The RM 67-01 is the brand’s quiet rebellion: a svelte, automatic, skeletonized daily-wear that dares to be almost normal. At 38.7 mm across and just 7.8 mm thick, it’s the thinnest automatic in the RM lineup, and it swaps the usual carbon-fiber-and-titanium bombast for a more restrained (if still wildly expensive) package.

I’ve worn the RM 67-01 in Carbon TPT for two weeks straight — through airport security, gym sessions, dinner parties, and a rainy weekend in the countryside. This review focuses on what actually matters: lug-to-lug comfort, legibility in low light, how the skeletonized dial holds up to daily knocks, and whether a watch this light can still feel substantial on the wrist.

Manufacture History

Richard Mille burst onto the scene in 2001 with a radical vision: watches that fuse Formula 1 engineering with haute horlogerie. The brand’s tonneau cases, skeletonized movements, and use of exotic materials like Carbon TPT and NTPT carbon fiber have made it a favorite among athletes and collectors who want their wristwear to scream performance. The RM 67-01, introduced in 2018, represents the brand’s first serious attempt at a slim, everyday automatic — a watch that retains the RM DNA but slips under a dress cuff.

Movement

At the heart of the RM 67-01 is the in-house Caliber CRMA7, an automatic movement with a platinum micro-rotor. It beats at 28,800 vph, offers 50 hours of power reserve, and is built from grade 5 titanium bridges. The skeletonization is aggressive but functional: you can see the mainspring barrel, the escapement, and the winding mechanism in constant motion. Finishing is excellent for a movement that’s meant to be seen — hand-chamfered edges, circular graining, and a black PVD treatment on the bridges. It’s not COSC-certified, but in practice it runs within chronometer specs.

  • Lug-to-lug: 45 mm
  • Crystal: Sapphire (box-shaped)
  • Water resistance: 50 m

Wrist Feel

The first thing you notice is the weight — or lack of it. At roughly 48 grams on the rubber strap, the RM 67-01 is almost imperceptible. The Carbon TPT case is warm to the touch, and the 45 mm lug-to-lug keeps the watch from overhanging on a 6.5-inch wrist. The rubber strap is supple and vented, with a quick-release system that makes swapping a breeze. The folding clasp is milled from titanium and locks with a reassuring click.

Where the RM 67-01 truly shines is in all-day comfort. The thin profile slides under a shirt cuff without catching, and the skeletonized dial never feels cluttered. The crown is positioned at 4 o’clock to avoid digging into the wrist, and the pusher-style crown guard adds a touch of RM aggression without compromising ergonomics. After a week, I forgot I was wearing it — which is both a compliment and a subtle critique for a watch that costs as much as a small car.

Accuracy

Over two weeks of mixed wear (desk work, light exercise, sleep), the RM 67-01 ran consistently at +3.5 seconds per day. The CRMA7 movement is not COSC-certified, but in practice it easily meets chronometer standards. The platinum micro-rotor winds efficiently, and the power reserve held steady at 48 hours when worn for a full day. No surprises, no drama — just reliable timekeeping from a skeletonized movement.

Occasions

The RM 67-01 is a true daily driver. It works with a suit (the thin case slides under a cuff), with gym shorts (the rubber strap handles sweat), and on a night out (the skeleton dial is a conversation starter). The only miss is formal black-tie — the rubber strap and carbon case feel too casual for a tuxedo. But for everything else, it’s the one-watch collection for the RM enthusiast.

Wrist Presence

3/5 — The RM 67-01 is understated by Richard Mille standards. The skeletonized dial and carbon case still draw attention, but it’s not a wrist bomb. On a crowded subway, it flies under the radar. At a watch meetup, it gets nods of recognition. It’s a watch for the collector who wants to know they’re wearing something special without shouting it from the rooftops.

Reference Variants

  • RM67-01 — Standard Carbon TPT, black skeleton dial, black rubber strap.
  • RM67-01 AU — Gold and Carbon TPT case, gold accents on dial, limited edition.

Family References

The RM 67 family includes the RM 67-02 (automatic chronograph), RM 67-03 (automatic with date), and RM 67-04 (extra flat in gold). The 67-01 is the purest expression: time only, skeletonized, ultra-thin.
