# Richard Mille RM 67‑02 Sprint – The Featherweight Automatic When Richard Mille unveiled the RM 67‑02 Sprint in 2017, the watch world was handed a paradox: a high‑priced, ultra‑luxury timepiece that weighed less than a typical smartphone. At a mere **32 g** and a scant **7.8 mm** thick, the Sprint claims the title of the lightest automatic in the brand’s catalogue, while still delivering a full‑blown in‑house movement and a bold visual language inspired by the South African flag. The question for any serious collector is whether the engineering marvel justifies its **$120,500** price tag and modest water resistance. Below we break down the watch’s anatomy, its heart, how it feels on the wrist, and whether it earns a place in a high‑end sports watch portfolio. --- ## Design & Case The RM 67‑02 Sprint is built around a **38.7 mm** diameter case that pushes the limits of thinness without sacrificing structural integrity. Richard Mille achieves this by marrying **Quartz TPT** (a high‑tech polymer) with **Carbon TPT** – a carbon‑reinforced composite that has become a signature material for the brand’s sport models. The result is a case that is both feather‑light and remarkably rigid, a necessary compromise when you’re packing a self‑winding calibre into a chassis that weighs only 32 g. Visually, the Sprint is unapologetically vibrant. The dial and case accents are rendered in **bright green and yellow**, a direct nod to the South African flag, and the colour scheme is carried through the hands, markers, and even the sapphire crystal’s subtle tint. The overall styling is described by aBlogtoWatch as “bright and brash,” yet the watch’s **skeletonised dial** offers a window into the movement, allowing the viewer to trace the rhythm of the rotating bridges and wheels. The case thickness of **7.8 mm** places the Sprint among the slimmest sport watches on the market, a feat that contributes to its ultra‑low profile on the wrist. The sapphire crystal is flat, not domed, reinforcing the watch’s “extra‑flat” moniker on the official product page. Water resistance is limited to **30 m**, which, while sufficient for rain and brief splashes, precludes any serious diving or high‑impact water sport usage. --- ## Movement & Performance At the heart of the Sprint beats the **Caliber CRMA7**, an in‑house automatic developed specifically for ultra‑thin applications. The movement is **skeletonised**, exposing 25 jewels and a **28,800 vph** (4 Hz) beat rate, which delivers a smooth sweep of the seconds hand while keeping the mechanism compact. Despite its minimal dimensions, the CRMA7 offers a respectable **50‑hour power reserve**, allowing the watch to run through a typical weekend without winding. The movement’s performance has been praised for its reliability; Hodinkee notes that both the Sprint and its sibling, the RM 67‑02 High‑Jump, are “the lightest automatic produced by Richard Mille and weighs only 32 grams.” The automatic winding system is efficient enough to keep the watch powered during normal daily activity, and the skeletonised architecture does not appear to compromise stability—an impressive engineering balance given the watch’s weight constraints. Accuracy figures are not disclosed in the source material, but the brand’s reputation for rigorous testing, combined with the movement’s high beat rate, suggests a level of precision consistent with other Richard Mille automatics. The 30 m water resistance, while modest, is not a performance flaw for a watch primarily intended for land‑based sport and daily wear. --- ## On the Wrist Wearing the RM 67‑02 Sprint feels like having a piece of technology rather than a traditional watch. The **lug‑to‑lug** spread, derived from the 38.7 mm case, sits comfortably on most wrists; the thin profile prevents the watch from “poking” out, a common issue with bulkier sport chronographs. The ultra‑light weight translates to a sensation of almost nothing on the hand—an attribute that many reviewers highlight as “remarkable” in everyday use. Comfort is further enhanced by the ergonomics of the TPT case, which distributes pressure evenly across the wrist. The flat sapphire crystal sits flush with the case, eliminating the “bubble” effect that can sometimes make a watch feel heavier. However, the watch’s **30 m water resistance** does impose a practical limitation: owners must remove the piece before swimming, snorkeling, or any activity that risks submersion beyond a few centimeters. For a sport watch, this is a notable compromise, though it aligns with the model’s focus on lightweight performance rather than aquatic endurance. The bright green‑yellow palette is unmistakable and may polarise tastes. It works best as a statement piece, drawing attention in a crowd. The skeletonised dial, while visually engaging, can be harder to read at a glance in low light compared to more traditional, high‑contrast dials. Nonetheless, the watch’s legibility remains acceptable thanks to generous hour markers and luminous treatment on the hands. --- ## Value & Verdict At **$120,500**, the RM 67‑02 Sprint occupies a niche reserved for collectors who prize engineering breakthroughs as much as brand prestige. The price point is undeniably steep, a fact echoed in the negative reviews that cite “the price tag… places it in the ultra‑luxury tier, limiting accessibility.” Yet, for those who value the combination of a **32 g automatic** and a daring, ultra‑thin construction, the Sprint delivers a proposition that few rivals can match. From a value perspective, the watch excels in three core areas: 1. **Technical Innovation** – Achieving a self‑winding movement in a 32 g package is a milestone that showcases Richard Mille’s mastery of material science and micro‑engineering. 2. **Design Distinction** – The bold colour scheme and flat aesthetic set it apart from the more subdued tones of traditional sport watches. 3. **Wearability** – The thin, feather‑light case translates to everyday comfort rarely found in high‑complication pieces. Conversely, the watch’s drawbacks are equally clear: - **Limited Water Resistance** – 30 m is insufficient for serious water‑sport enthusiasts. - **High Price** – The cost is comparable to many full‑diamond or complication‑laden timepieces that offer broader functional capabilities. **Verdict:** The RM 67‑02 Sprint is less a conventional sport watch and more a proof‑of‑concept that a high‑luxury brand can strip down an automatic to its barest, lightest form without sacrificing reliability. If you are a collector fascinated by material innovation, enjoy a bold visual statement, and are comfortable keeping the watch out of deep water, the Sprint justifies its price as a showcase of what modern composites and micro‑engineering can achieve. For anyone seeking a versatile, water‑resistant sports chronograph, the Sprint’s limitations may outweigh its feather‑light charm. In the end, the RM 67‑02 Sprint stands as a testament to Richard Mille’s willingness to push boundaries—an ultra‑light, ultra‑thin marvel that, despite its high cost and modest water resistance, delivers an unforgettable wearing experience that few other watches can replicate.
