Richard Mille RM 65-01 Automatic Split Seconds Chronograph NTPT Skeletonized on Rubber Strap.

Richard Mille introduces its first split seconds chronograph with an automatic movement. A highly complex sports timepiece designed for everyday use and for any situation. The culmination of some five years of development, this automatic split seconds chronograph is the most complex timepiece ever to leave the Richard Mille workshops.

This chronograph runs on a high frequency balance with variable inertia—5 Hz, or 36,000 vibrations per hour—developed for superior timekeeping accuracy over an extended period and precise stopwatch calculations to 1/10th of a second. It is every bit a genuine racing machine with a split-second hand to calculate intermediate times, a first for Richard Mille on an automatic movement.

Developed in partnership with Vaucher Manufacture Fleurier, the Richard Mille RM 65-01 Automatic Split Seconds Chronograph integrated movement uses a 6-column wheel architecture and vertical coupling. Like a mechanical brain, this castellated piece orchestrates the controls and can be seen through the base. A mechanical cathedral—standing on a grade 5 titanium chassis supported by grade 5 titanium bridges—it receives its energy from a fast-rotating barrel that maintains ideal torque for energy transmission for the full duration of its 60-hour power reserve. The barrel’s automatic winding also ensures the watch sustains optimal torque whilst worn on the wrist. This is further enhanced by the variable geometry of the calibre’s oscillating weight segment, which makes it possible to change the rotor’s inertia for improved winding yield depending on the more or less active profile of the person bearing the watch.

The movement architecture of the RM 65-01 split seconds chronograph is nicely laid out as seen through the sapphire case back. While the double column wheels and braking systems of the split seconds mechanism is not visible, the labyrinth of bridges laid out in the back is aesthetically very pleasing and reminiscent of the image of a racing car on the wrist that Richard Mille likes to portray.

The chronograph was also subjected to a battery of merciless tests to demonstrate its capacity to function under any circumstances. These included everything from shock and drop simulations to accelerated 10-year ageing phases for all functions, by way of waterproof tests and magnetic field resistance trials.

But the Richard Mille teams did not stop there. No indeed, to this powerful, solid and infallible racing engine, mounted on a Carbon TPT case as resistant as it is light, they added complications to boost the model’s ergonomics. In another milestone, Richard Mille developed its first in-house patented rapid-winding mechanism, activated by a pusher at 8 o’clock. In 125 presses, the barrel is fully wound, ready to time your next event. This highly practical function, described as ‘very playful’ by Richard Mille’s engineers, was particularly difficult to develop because of its high levels of torque transfer. During the ageing tests, the function was activated thousands of times.

The model was also enhanced with a new gearbox, taking the form of a function selector housed in the crown. This system makes it possible to switch between ‘traditional’ winding (W), semi-instantaneous date adjustment (D) or setting the time (H), all done simply by pressing the crown.

For a supremely legible dial, the RM 65-01 uses color-coding to match watch functions with the pushers. Yellow is for time: hours, minutes, small seconds at 6 o’clock, whereas green refers to the date display. Orange identifies the chronograph’s sweep seconds hand as well as the 30-minute and 12-hour totalizers. Red is linked to the winding mechanism. To avoid all confusion, the split-seconds hand is blue. Here, function is what drives the aesthetical choices.

As for the case, its every surface boasts extremely elegant detailing. Sporting a Carbon TPT bezel, caseband and caseback, it has a microblasted, polished and satin-finished grade 5 titanium crown, framed by the chronograph buttons, also in polished and satin-finished grade 5 titanium. The same material and finish are used for the plate engraved with RM 65-01 on the caseband. The rapid-winding pusher stands out with its red Quartz TPT button.
