Making its debut as the brand’s first automatic split-seconds chronograph, the RM 65-01 epitomises Richard Mille’s expertise. It serves as a foundation for other collections, showcasing a unique design that blends advanced technology with exceptional craftsmanship, all highlighted by a distinctive tonneau-shaped case.
In developing this timepiece for the 21st century, the engineers started with a blank slate, guided by a clear vision: to create a timekeeping instrument committed to excellence, perfection, and innovation. Regarded as the most complex automatic chronograph watch, the RM 65-01 is capable of tracking performance to a tenth of a second. To measure intermediate times, it incorporates a split-seconds hand and replaces the traditional hand-wound system with an automatic winding mechanism, marking a first for a Richard Mille split-seconds chronograph.
Once these principles were established, the choice of an integrated movement became clear, aligning with the grand traditions of haute horlogerie. To stay true to this noble approach to measuring short intervals, a six-column wheel architecture was selected. This castellated component, visible through the caseback, acts as a mechanical brain, orchestrating commands with precision. Additionally, vertical coupling ensures immediate and accurate measurements without hand jumping during the start and stop of the chronograph.
The RM 65-01 collection illustrates the full spectrum of Richard Mille’s talent and mastery. Continuously evolving, it recently expanded to include a collaboration with McLaren, one of the brand’s long-standing partners. From the original RM 65-01 launched in 2020 to the latest iterations in Pastel Blue and Dark Yellow Quartz TPT, the collection transcends the limits of horological artistry.
RM 65-01 McLaren W1
The latest addition for Richard Mille collectors is the RM 65-01 McLaren W1, a limited edition automatic chronograph watch inspired by the McLaren W1 supercar. At the heart of the watch is the RMAC4 movement, which represents the pinnacle of Richard Mille’s automatic chronograph calibres. After nearly five years of development, this model is the brand’s first automatic split-seconds chronograph and showcases Richard Mille’s technical mastery, providing a fresh take on a complex motorsport chronograph.
Featuring a unique frequency of 5Hz (36,000 vibrations per hour), the RM 65-01 McLaren W1 solidifies the brand’s commitment to precise timekeeping, as a “simple” chronograph would not meet performance standards at this level. To measure intermediate times, the watch includes a split-seconds hand, and for the first time in a Richard Mille split-seconds chronograph, it replaces the traditional hand-wound system with an automatic winding mechanism. This decision led to the use of an integrated movement, a hallmark of haute horlogerie. A six-column wheel architecture ensures precise measurement of short intervals, and the vertical coupling mechanism provides immediate, accurate readings without hand jumping.
Built on a grade 5 titanium chassis with corresponding lightweight bridges for optimal rigidity, the watch is powered by a fast-rotating barrel that maintains ideal torque for energy transmission while minimising friction. The calibre’s performance is enhanced by using 20° involute profile teeth. The automatic winding system guarantees optimal torque when worn, aided by the variable geometry of the oscillating weight that adjusts the rotor’s inertia based on the wearer’s activity level.
With impressive dimensions of 43.8×49.94×16.19 mm, the RM 65-01 McLaren W1 boasts a compact yet commanding presence on the wrist. Its construction features a bezel meticulously polished and satin-finished in Carbon TPT and grade 5 titanium, offering a sophisticated contrast in textures. The seamlessly integrated caseband is crafted from lightweight, high-strength Carbon TPT, while the caseback reveals the intricate mechanics within. A notable design element is the carbon fibre-infused luminescent interior flange, enhancing readability in low light.
RM 65-01 Automatic Split-Seconds Chronograph
The RM 65-01 Automatic Split-Seconds Chronograph in Dark Yellow Quartz TPT and Pastel Blue Quartz TPT is an intricate timepiece that took five years to perfect. Featuring an automatic split-seconds chronograph, its complexity lies in the six-column wheel within the calibre RMAC4, which governs time measurement.
From a technical perspective, this movement showcases fine craftsmanship with a high-frequency balance oscillating at 36,000 vibrations per hour and featuring variable inertia. Comprising 600 parts, the calibre RMAC4 is the most intricate of all the brand’s automatic movements, providing precise chronometric data for the RM 65-01 Split-Seconds Chronograph.

The chronograph underwent extensive testing to ensure flawless operation in various scenarios, including shock and drop simulations, accelerated 10-year ageing trials for all functions, waterproof assessments, and resistance to magnetic fields.
Every detail of this timepiece reflects a commitment to precision. For instance, the pusher located at 8 o’clock is designed to quickly recharge the spring in the fast-rotating barrel. A full press of this pusher resets the barrel, allowing for convenient re-energising of the watch if it has been unworn for an extended period. This practical feature, described as “very playful” by Richard Mille’s engineers, posed significant challenges during development due to the high torque transfer involved. Throughout the ageing tests, this function was activated thousands of times to verify its reliability and durability.
Additionally, the chronograph includes a 60-hour power reserve. Using the function selector on the crown, the wearer can effortlessly switch from traditional winding mode (W) to semi-instantaneous date adjustment (D) or adjust the hours and minutes (H).
Adding to its allure, Richard Mille brings vibrant shades of summer to the RM 65-01 with Dark Yellow Quartz TPT and Pastel Blue Quartz TPT. While these colours introduce a whimsical touch, achieving such hues involves much more than a simple paintbrush. The research and development team spent months perfecting the specific shades to meet the brand’s stringent colour and quality standards.
For instance, to create the desired pastel blue Quartz TPT, silica fibers are layered to a maximum thickness of 45 microns and infused with a custom blue resin developed exclusively for Richard Mille. The yellow Quartz TPT enhances warmth and brilliance, allowing the intricate inner workings to be visible through the skeletonised dial.
Both models benefit from Quartz TPT, a material developed by NTPT (North Thin Ply Technology). This composite features multiple layers of silica fibers, saturated with resins specifically designed for Richard Mille, and is heated to 120°C under 6 bars of pressure. The result is a material with exceptional durability that enhances the watch’s aesthetics by adding a touch of elegance.
