Richard Mille RM 67 Buying Guide: RM 67-01 & RM 67-02 Specs, Prices | Ultimate Watch

The Richard Mille RM 67 is the extra-flat side of a brand most people know for wrist-sized machinery. When Richard Mille showed the RM 67-01 Automatic Extra Flat at SIHH 2016, it was the first time the house built a genuinely thin watch inside its signature tonneau case. The case measures 38.7mm wide by 47.52mm long and just 7.75mm thick, which for a Richard Mille is svelte. Inside sits the automatic caliber CRMA6, a movement only 3.6mm thick, skeletonized and shaped to follow the curve of the case. The line grew a second branch in 2019 with the RM 67-02, a competition watch built for track and field athletes, made from Quartz TPT and Carbon TPT, riding on a seamless elastic textile strap, and weighing about 32 grams complete. That number matters: the RM 67-02 is the lightest automatic watch Richard Mille has ever produced. We are Ultimate Watch, the authority arm of Ultimate Diamond at 19 West 47th Street in New York, family-owned since 1959. We buy and sell RM 67s across the counter, and this entry is written the way we talk about them when a client puts one on the tray.

Collector's Lore

The RM 67-01 is remembered as a turning point in how the market read Richard Mille. Before it, the shorthand was big, loud, and heavy. The 7.75mm case forced a rethink; here was an RM that behaved like a flat watch and still looked like an RM under the loupe, skeletonized and tonneau-shaped rather than borrowed from a round movement. The 67-02's origin story is the one collectors repeat: watches engineered to be worn during actual competition by Wayde van Niekerk and Mutaz Essa Barshim at the highest level of athletics, with the entire package driven under about 32 grams. The seamless stretch textile strap was a genuine engineering exercise, described by the brand as the lightest strap it had ever made, and it is a big part of how a mechanical automatic got that light. Among RM people, choosing a 67 over a chronograph or tourbillon is a quiet flex: you know the brand well enough to want the thin one you can actually live in.
