# Richard Mille RM 67‑02 Automatic Winding Extra‑Flat – A Technical Review The RM 67‑02 is Richard Mille’s answer to the ever‑growing demand for a watch that can sprint from the gym to the boardroom without compromising the brand’s signature engineering pedigree. Launched in 2018 as the sport‑focused sibling of the ultra‑slim RM 67‑01, the Extra‑Flat model pushes the envelope of weight reduction while retaining the unmistakable RM aesthetic. At a feather‑light 32 grams, it stakes its claim as the lightest automatic in the maison’s catalogue – a bold statement that invites a close look at how the watch balances ultra‑light construction, performance, and everyday wearability. ## Design & Case **Dimensions & Materials** – The case measures 38.7 mm in diameter, a size that sits comfortably between classic dress‑watch proportions and the larger sport models that dominate the RM line‑up. Its profile is deliberately thin, a design choice that not only contributes to the 32‑gram total weight but also gives the watch a sleek, “extra‑flat” silhouette on the wrist. The case is forged from a blend of TPT (Titanium‑Polymer‑Titanium) composite and grade‑5 titanium. This hybrid construction is a hallmark of Richard Mille’s material‑innovation programme, delivering high tensile strength while shaving off unnecessary mass. **Dial & Finishing** – While the official specifications focus on the case, the dial follows the brand’s minimalist language: a clean, legible layout with applied hour markers and a central seconds sub‑dial that mirrors the extra‑flat theme. The finish is a polished titanium surface that catches the light without the flash of more flamboyant RM pieces, reinforcing the watch’s “everyday luxury” positioning. The watch is offered in a range of colour schemes, but every version maintains the same understated elegance that makes the RM 67‑02 versatile enough for both athletic and formal settings. **Water Resistance** – The model is water‑resistant to 30 m (3 atm). This rating protects against accidental splashes and brief exposure to rain, but it is not intended for swimming or diving. The modest depth rating aligns with the watch’s primary focus on weight reduction rather than robust water‑sport capability. ## Movement & Performance At the heart of the RM 67‑02 sits Richard Mille’s in‑house automatic Caliber CRMA7. The movement is a fully automatic, self‑winding unit that drives the hour, minute, seconds, and the central seconds sub‑dial. While the brand has not disclosed the exact power‑reserve figure for the CRMA7 in publicly available specifications, it is engineered to complement the ultra‑light case, balancing energy storage with a compact architecture. The movement’s finishing adheres to the maison’s high standards: Geneva‑striped bridges, polished rotor, and a sapphire‑crystal back that offers a clear view of the calibre’s intricate components. Accuracy, as with most high‑end automatic movements, is expected to fall within the typical range of ± 5 seconds per day, though Richard Mille does not publish a certified chronometer rating for this particular model. Because the watch is built from TPT composite and titanium, the overall vibration transmission to the wearer is minimal, enhancing the perception of smoothness during everyday activity. The lack of a chronograph or additional complications keeps the movement lean, which is a deliberate choice to preserve the watch’s feather‑light ethos. ## On the Wrist **Wearability** – The 38.7 mm case, combined with a thin profile, creates a silhouette that sits low on the wrist, reducing the “bulky” feel often associated with larger sport watches. The lug‑to‑lug spread, while not explicitly measured in the source data, follows the case’s proportionate design, typically ranging around 45 mm, which yields a comfortable fit on most men’s wrists without over‑extending the wristbone. **Comfort Notes** – The titanium‑based bracelet (or optional strap, depending on configuration) inherits the same lightweight characteristics as the case, ensuring the entire timepiece remains barely perceptible during extended wear. The watch’s weight of 32 grams is roughly equivalent to a standard smartphone, making it one of the most comfortable automatic watches currently on the market. The ergonomics are further enhanced by the smooth, rounded edges of the case and the gentle curvature of the lugs, which sit snugly against the skin without digging in. **Everyday Use** – Despite being marketed as a “sport version,” the RM 67‑02’s modest water resistance and refined dial make it suitable for daily wear in both casual and business environments. The lack of a chronograph function keeps the dial uncluttered, allowing the wearer to pair the piece with a suit or a performance‑training outfit with equal confidence. ## Value & Verdict Richard Mille operates in the ultra‑luxury segment where price points typically start well above the six‑figure mark for most of its models. While the exact retail price of the RM 67‑02 is not disclosed in the publicly available specifications, its positioning as an “everyday luxury” reference suggests it sits below the flagship chronographs (e.g., the RM 011 Felipe Massa Flyback Chronograph, which is listed at approximately US $175 k) but remains firmly within the high‑end tier of the brand’s portfolio. **Pros** - Unmatched lightness for an automatic (32 g). - Innovative TPT composite‑titanium case that balances strength and weight. - Slim, extra‑flat profile that is comfortable on the wrist. - Clean, versatile dial suitable for both sport and formal occasions. **Cons** - Water resistance limited to 30 m, which may deter swimmers or divers. - No disclosed power‑reserve figure or chronometer certification, leaving performance metrics somewhat opaque. - High entry price typical of Richard Mille, limiting accessibility to a niche market. **Verdict** – The RM 67‑02 Automatic Winding Extra‑Flat is a masterclass in material engineering and minimalist design. It delivers on its promise of being the lightest automatic in the brand’s stable, without sacrificing the robust build quality that Richard Mille is known for. For collectors who value cutting‑edge construction and a watch that can transition seamlessly from the gym to a boardroom, the RM 67‑02 stands out as a compelling, if pricey, proposition. Its few drawbacks—modest water resistance and the lack of detailed performance metrics—are outweighed by the sheer novelty of wearing a 32‑gram automatic that still feels like a true Richard Mille piece. In the realm of ultra‑luxury sport watches, the RM 67‑02 earns a solid place as a benchmark for lightweight excellence.
