A highly complex sports timepiece, a masterpiece of technical prowess designed for everyday use and for any situation, such is the latest execution of Richard Mille’s tireless quest for innovation, the new RM 65-01.

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 model fully embodies the brand’s technical approach thanks to the combination of several additional functions, a very specific architecture and an extremely high-end aesthetic. All in all, a fabulous challenge of mechanical watchmaking that called for patience, technicity and utter perseverance.

The RM 65-01 is our interpretation of a highly complex motorsport inspired chronograph. It fully embodies our technical approach thanks to the combination of several additional functions, a very specific architecture and aesthetics of the highest order.

Calibre	RMAC4 - Skeletonized automatic winding movement with hours, minutes, seconds at 6 o’clock, date, split-seconds chronograph with 30-minute counter at 3 o’clock, 12-hour counter at 9 o’clock, function selector, rapid winding and variable-geometry rotor.
Power Reserve	Around 60 hours (± 10%).
Baseplate and Bridges	The baseplate and the bridges are crafted of grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautical and automobile industries. The baseplate of the calibre RMAC4 has been optimized for an extremely low weight / resistance ratio.
Chronograph	The RMAC4 calibre is equipped with the latest-generation split-seconds mechanism developed by the engineers at Richard Mille. The 6-column wheel ensures optimized simultaneous movement, maximal function locking, and greater adjustment durability.
Rapid Winding System	The rapid winding mechanism was developed in addition to the automatic winding and winding with the crown. It allows the barrel to be quickly rearmed in the event the watch stops. By pressing on the pusher at 8 o’clock, you allow the barrel to be fully reset. This function is ideal for quickly rearming the watch if not worn for a long time. 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.
Function Selector	The RM 65-01 is constructed with a highly specialized gearbox design for Winding, Date and Hand Setting functions. To shift back and forth through these different functions, use the pusher located at the center of the crown until the desired function is selected. The hand located at 4 o’clock will indicate W, D or H accordingly.
Rotor	The RM 65-01 uses a newly designed variable geometry to optimize the rotor’s winding motion.
