Introducing: The Richard Mille RM 65-01 Automatic Split-Seconds Chronograph In Yellow And Blue Quartz TPT

What We Know

Last week, Richard Mille added two new colors to the RM 65-01 lineup. First launched back in 2020, the RM 65-01 is made of 600 components total and is the most complicated automatic (non-LE) watch to be produced by the brand. The very saturated yolky shade of yellow will exist as a limited run of 120 watches, and the pastel blue will become a staple in the collection. Both are made of Quartz TPT or Thin Ply Technology (Quartz TPT was first developed for the RM 27-02 Nadal), which is a composite made of multiple layers of quartz fibers, which are generally used for very high-performance applications due to their resistance to high temperatures, their strength, and their transparency to electromagnetic waves.

Richard Mille, with its focus on motorsports, has long focused on highly complex chronographs. Starting with the RM 004, a manually-wound, split-second powered by a Renaud & Papi caliber, these new RM 65-01s are the latest in the lineage. This high-beat, self-winding rattrapante chronograph features Caliber RMAC4, a high-frequency movement with variable inertia, oscillating at 36,000 vibrations per hour (vph)/5 Hz. The RMAC4 in the RM 65-01 is supplied by Vaucher and was originally based on the architecture and layout of the Parmigiani caliber PF361.

I’m not really one for frequency talk, but it’s pretty helpful to take a little frequency crash course (brush up on your knowledge here) in order to understand this model. Technically, a chronograph operating at 5 Hz is more functional than the more common 4 Hz alternative. A movement running at 5 Hz has a balance that is physically oscillating at 36,000 vph; on the dial side, this translates to the ability to measure elapsed time (the whole goal of a chronograph, after all – just ask Zenith) in one-tenth-of-a-second intervals, compared to one-eighth of a second with a chronograph running at 4 Hz.

Equipped with a vertical clutch and dual six-column wheels for a smooth pusher feel (hey, you get what you pay for), the chronograph is capable of timing events up to 12 hours. The total power reserve is 60 hours, while a variable-geometry rotor optimizes winding according to the wearer’s activity. …read more
