Richard Mille RM 30-01 Automatic Winding with Declutchable Rotor

White ATZ Ceramic & Grade 5 Titanium

The Richard Mille RM 30-01 Automatic Winding with Declutchable Rotor represents an exceptional fusion of avant-garde design, advanced materials engineering, and sophisticated Swiss watchmaking. Featuring the brand’s iconic tonneau-shaped architecture, this timepiece showcases an innovative mechanical movement housed in a striking combination of white ATZ ceramic and Grade 5 titanium.

Case and Materials

The watch features a distinctive tonneau-shaped case measuring approximately 49.94 mm × 42.00 mm, with slight variations in reported dimensions. The bezel and caseback are crafted from high-performance white ATZ ceramic, offering exceptional scratch resistance with a hardness rating of approximately 1,400 Vickers. The micro-blasted Grade 5 titanium central caseband complements the ceramic components, delivering strength, durability, and a sophisticated technical aesthetic.

Movement and Mechanical Engineering

At its heart is the skeletonized RMAR2 automatic movement, operating at a frequency of 28,800 vibrations per hour (4 Hz) and incorporating 38 jewels. The movement provides an approximate power reserve of 55 hours.

One of its most distinctive innovations is the patented variable-geometry declutchable rotor system. When the power reserve reaches approximately 55 hours, the rotor automatically disengages from the winding barrel train, preventing excessive mainspring tension and minimizing unnecessary mechanical friction. It automatically re-engages when the power reserve drops to approximately 40 hours, ensuring efficient and controlled winding.

Complications and Functions

The RM 30-01 incorporates several practical and sophisticated indications:

• • Oversized date display.

• • Power reserve indicator.

• • Rotor clutch engagement/disengagement indicator.

• • Function selector with Winding (W), Date (D), and Hand-setting (H) modes.
