Richard Mille RM Extra Flat Watch

Richard Mille RM 67-01 Extra Flat: The Sleekest Tonneau Icon

The Richard Mille RM 67-01 Extra Flat represents a daring evolution of the brand’s signature tonneau shape, reimagined in an incredibly slender and ergonomic profile. As the sleekest tonneau-shaped watch in the Richard Mille collection, the RM 67-01 achieves a remarkable thickness of just 7.75 mm, allowing it to slide effortlessly under a dress cuff while maintaining a powerful wrist presence. The design explores extreme skeletonization, creating a mesmerizing sense of depth that draws the eye from the edges of the multi-layered bezel into the heart of the movement. It is the perfect “lifestyle” timepiece for those who value Richard Mille’s technical bravado in a more discreet and refined form.

In-House Innovation and Architectural Transparency

At the core of this masterpiece is the Calibre CRMA6, an in-house automatic movement measuring a mere 3.6 mm in height. To achieve its ultra-flat status, Richard Mille engineers crafted the baseplate and bridges from Grade 5 titanium, finished with grey and black electroplasma treatments for maximum rigidity. The dial features a unique construction where the Arabic numerals are sculpted from solid metal and mounted on titanium rails that attach directly to the movement—a first for the brand. Complete with a function indicator (W/D/H) and a vertical date window at 5 o’clock, the RM 67-01 is a triumph of engineering that balances high-performance mechanics with the elegance of a classic dress watch.
