The RM 65-01 Automatic Split-Seconds Chronograph is the culmination of five years of meticulous development, a testament to Richard Mille's relentless pursuit of perfection. This timepiece represents the brand's most intricate and sophisticated automatic caliber to date, a symphony of over 600 meticulously crafted components working in harmonious unison. It is a watch that not only tells time but also tells a story of passion, dedication, and the unwavering pursuit of mechanical excellence.

Richard Mille has long been associated with the world of motorsports, and the RM 65-01 is a testament to this enduring connection. Inspired by the high-octane world of racing, this chronograph is designed to withstand the rigors of extreme conditions while maintaining impeccable accuracy and reliability. The watch's architecture reflects this motorsport heritage, with bold lines, robust construction, and an overall aesthetic that exudes a sense of dynamism and power.

The new pastel blue and dark yellow Quartz TPT® cases are not just visually striking but also incredibly durable and lightweight. This revolutionary material, known for its exceptional strength-to-weight ratio, is composed of multiple layers of parallel filaments obtained by dividing carbon fibers. These layers are then impregnated with a colored resin specifically developed for Richard Mille, creating a vibrant and unique aesthetic that is both eye-catching and technically advanced.

The pastel blue Quartz TPT® case, with its serene and refreshing hue, is reminiscent of a clear summer sky, evoking a sense of tranquility and elegance. The dark yellow Quartz TPT® case, on the other hand, is a bold and energetic statement, radiating the warmth and brilliance of the sun. Both colorways offer a distinct personality to the RM 65-01, allowing collectors to choose the one that best resonates with their individual style and preferences.

Beyond its striking aesthetics, the RM 65-01 is a horological masterpiece that boasts an impressive array of technical features. At its heart beats the Caliber RMAC4, a skeletonized automatic winding movement that powers the watch's various functions, including hours, minutes, seconds, date, and a split-seconds chronograph. The chronograph, a complication prized by watch enthusiasts for its ability to measure elapsed time with precision, is a testament to Richard Mille's dedication to horological innovation. The RM 65-01's chronograph features a 30-minute counter at 3 o'clock and a 12-hour counter at 9 o'clock, allowing for precise timing of events.

The RM 65-01 also features a rapid winding mechanism, a function selector, and a variable-geometry rotor, all of which contribute to the watch's exceptional performance and user-friendliness. The rapid winding mechanism allows the wearer to quickly wind the mainspring, ensuring that the watch remains powered even after periods of inactivity. The function selector, located at the center of the crown, enables seamless switching between winding, date setting, and hand setting functions. The variable-geometry rotor, an innovation patented by Richard Mille, optimizes the winding of the mainspring based on the wearer's activity level, ensuring efficient energy generation whether the wearer is engaged in leisurely pursuits or high-intensity activities.

The heart and soul of this extraordinary timepiece lie in its intricate movement, the Caliber RMAC4. This skeletonized automatic winding movement is a testament to Richard Mille's dedication to pushing the boundaries of mechanical watchmaking. With over 600 meticulously crafted components, the RMAC4 is a masterpiece of engineering, a symphony of gears, levers, and springs working in perfect harmony. The movement's skeletonized design not only reveals its inner workings but also adds a touch of visual drama, allowing the wearer to appreciate the intricate ballet of mechanical components in action.

One of the standout features of the RM 65-01 is its split-seconds chronograph, a complication that allows for precise measurement of intermediate times. This feature, a first for Richard Mille in an automatic movement, is a testament to the brand's commitment to innovation. The chronograph is operated by two pushers on the side of the case, one to start and stop the chronograph and the other to split the timing. The split-seconds hand, distinguished by its unique color, allows the wearer to record intermediate times without interrupting the ongoing timing, making it an invaluable tool for racing enthusiasts and those who demand precision timing.

The RM 65-01's case, available in either pastel blue or dark yellow Quartz TPT®, is a marvel of material science. Quartz TPT® is a high-performance composite material known for its exceptional strength, lightness, and resistance to scratches and impacts. This innovative material, developed in collaboration with North Thin Ply Technology (NTPT®), is composed of multiple layers of parallel filaments obtained by dividing silica fibers. These layers are then impregnated with a colored resin specially developed for Richard Mille, creating a vibrant and unique aesthetic that is both eye-catching and technically advanced.

Despite its size, the RM 65-01 remains remarkably comfortable to wear thanks to its ergonomic design and lightweight construction. The case's tonneau shape, a signature Richard Mille design element, not only enhances the watch's aesthetic appeal but also contributes to its ergonomic fit.

The RM 65-01's dial is a feast for the eyes, with its skeletonized design revealing the intricate workings of the movement. The dial's layout is both functional and visually appealing, with the hours, minutes, and seconds displayed on subdials, while the chronograph counters and date aperture are strategically positioned for optimal legibility. The dial's vibrant color scheme, with contrasting accents for the hands and markers, enhances readability and adds a touch of sporty flair to the overall aesthetic.
