Richard Mille RM 74‑01 Automatic Tourbillon

The RM 74‑01 houses Richard Mille’s in‑house CRMT6 calibre, an ultra‑skeletonised automatic tourbillon movement offering around 50 hours of power reserve. At its core is a free‑sprung balance with variable inertia, adjusted via four micro‑weights for superior accuracy and shock resistance.

The case measures approximately 52.6 × 34.4 mm and is crafted in grey Cermet—an exclusive Richard Mille composite combining the lightness of titanium with the hardness of ceramic—while the caseband, baseplate, and bridges use Grade 5 titanium for strength and durability.

Unique to this model is the variable‑geometry rotor, allowing owners to adjust rotor inertia to suit their activity level, ensuring optimal winding efficiency.

The dial features a fully skeletonised layout, showcasing the movement’s intricate mechanics with visibility down to the tourbillon at 6 o’clock, all protected under a sapphire crystal and paired with a rubber strap for sporty comfort.

To sum up, the RM 74‑01 blends avant‑garde materials, technical innovation, and minimalist elegance in a slim tonneau‑shaped form—ideal for those seeking haute horology with a modern edge.
