After 5 years of development, Richard Mille presents the most complicated automatic chronograph to date – the new RM 65-01. The model fully represents the technical approach of the brand thanks to the combination of several additional functions, a very specific architecture and a high aesthetic. This timepiece is made from more than 600 parts.
The iconic case of the RM 65-01 Automatic Split-Seconds Chronograph features Richard Mille’s proprietary layered carbon TPT material and a mix of red gold and carbon TPT, measuring 44mm x 49.9mm. This timepiece features a skeletonized self-winding movement, hours, minutes, seconds at 6 o’clock, date, split-seconds chronograph, 30-minute counter at 3 o’clock and 9 o’clock 12-hour counter, function selector, fast winding and variable geometry rotor.
The new split-seconds chronograph is powered by the new RMAC4 split-seconds chronograph movement, developed in collaboration with movement specialist Vaucher Manufacture Fleurier. The modern architecture of the movement allows for a consistent and rational arrangement of its components, avoiding unnecessary superposition and enabling optimal use of functions through technical solutions. The RMAC4 movement is equipped with the latest generation of split-seconds mechanism developed by best Richard Mille engineers. The 6-column wheel ensures optimized synchronized movement, maximum functional locking and greater adjustment durability.
The baseplate and bridges are made of grade 5 titanium, a biocompatible, highly corrosion-resistant, rigid alloy that allows the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminum and 4% vanadium. This combination further improves the mechanical properties of the material. The baseplate of the movement RMAC4 has been optimized for an extremely low weight/drag ratio. The skeletonized baseplates and bridges were tested to optimize their resistance capacity.
Chronographs undergo a variety of tests to prove their correct function in any situation, from shock and drop simulations to a 10-year accelerated aging period for all functions, to water resistance tests and tests against magnetic fields.
For an extremely clear dial, the RM 65-01 uses color coding to match the functions corresponding to the buttons. Yellow represents the time: hours, minutes, small seconds at 6 o’clock. Green refers to the date display. Orange identifies the sweeping seconds hand of the chronograph and the 30-minute and 12-hour totalizers. Red is connected to the winding mechanism, and the double rattrapante is blue.
