Richard Mille RM 65-01 Split Seconds Chronograph Overview
The Richard Mille RM 65-01 Split Seconds Chronograph represents one of the most technically advanced chronographs created by the brand. This model introduces a newly developed column-wheel split-seconds automatic chronograph movement, paired with a unique push-type rapid winding mechanism—a first for Richard Mille. It stands as one of the most complex and performance-oriented chronographs in modern watchmaking.
Carbon Tonneau Case and Pusher System
The tonneau-shaped case of the Richard Mille RM 65-01 Split Seconds Chronograph is crafted from lightweight and highly durable carbon fiber. Chronograph pushers are positioned at 2 and 4 o’clock, with the split-seconds actuator at 10 o’clock. A distinctive red pusher at 8 o’clock operates the rapid-winding mechanism, which fully winds the barrel with 125 presses. This introduces significant mechanical complexity, especially in terms of precise torque management.
Color-Coded Dial Functions
The RM 65-01 showcases an open-worked dial with color-coded indicators for optimal legibility.
• Yellow — hours, minutes, running seconds
• Orange — chronograph counters and central chronograph seconds
• Light blue — split-seconds hand
• Green — date display at 11 o’clock
The signature function selector remains at 5 o’clock, a signature feature of Richard Mille chronographs.
Caliber RMAC4 — High-Performance Automatic Movement
The Richard Mille RM 65-01 Split Seconds Chronograph is powered by the new Caliber RMAC4 automatic skeleton movement, delivering a 60-hour power reserve. With a 36,000 vph high-frequency balance, the chronograph measures intervals with 1/10-second precision. The baseplate and bridges are crafted from Grade 5 titanium, ensuring rigidity and stability. A variable-geometry rotor adapts winding efficiency to the wearer’s activity.
Rigorous Durability Testing
To meet Richard Mille’s extreme durability standards, the RM 65-01 undergoes demanding testing conditions, including:
• Simulated shock and drop testing
• 10-year accelerated aging tests
• Waterproofing and anti-magnetic certification
These evaluations ensure the chronograph remains reliable under the harshest usage scenarios.
The official retail price is 270,000 Swiss francs, positioning it among the brand’s most technically advanced and collectible models.
