Richard Mille | Reference RM65-01 | A Titanium Skeletonized Split Seconds Chronograph 50mm Wristwatch

The Richard Mille RM 65-01 Split-Seconds Chronograph is a mechanical masterpiece, representing the pinnacle of the brand’s horological engineering.

This extraordinary titanium timepiece redefines high-end luxury by combining uncompromising precision with a sophisticated, race-inspired architecture.

Developed in collaboration with Vaucher Manufacture Fleurier, the Richard Mille RM65-01 is powered by the heavily skeletonised, integrated Calibre RMAC4. This formidable engine operates at a high frequency of 36,000 vibrations per hour (5 Hz) to ensure exceptional precision and stopwatch calculations down to 1/10th of a second.

Key specifications that elevate this timepiece include:

1. The Elite Architecture: The movement is anchored by a baseplate and bridges crafted from Grade 5 titanium, a biocompatible, highly corrosion-resistant alloy heavily favored in the aerospace sector.

2. Mechanical Ingenuity: Features a 6-column wheel split-seconds mechanism, a rapid-winding pusher at 8 o’clock (125 presses fully arms the mainspring), and a variable-geometry rotor.

3. Power & Control: Delivers approximately 60 hours of power reserve, managed elegantly via a crown-based function selector hand (W for Winding, D for Date, H for Hand Setting).

4. Design & Scale: Measuring 44.5 mm × 49.94 mm, the watch wears beautifully, with a color-coded dial that makes navigating its rich functionalities—including a 30-minute and 12-hour counter—flawlessly intuitive.
