Richard Mille Automatic Winding Split-seconds Chronograph – RM 65-01

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.

CALIBRE RMAC4

Skeletonised 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.

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

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. 

POWER RESERVE

Around 60 hours (± 10%).

Actual power reserve results will depend on how much the chronograph features are utilised.

High-Frequency Balance With Variable Inertia

Beating at 5Hz (36,000 vph), the fast-beating free-sprung balance offers better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time, keeping a more accurate time. This new type of balance at Richard Mille can measure accurately to 1/10th of a second, ideal for a split-seconds chronograph watch under sporting conditions.
The regulator index is eliminated, and a more accurate and repeatable adjustment is possible thanks to 4 small, adjustable weights located directly on the balance.
