Designed for those seeking a unisex timepiece combining sporty materials with jewelry flair, the RM037 offers beauty and performance in one statement package.

Overview

The RM037 is part of Richard Mille’s collection of “ladies’” or smaller tonneau‑shaped models, but with a strong mechanical identity. It balances aesthetic refinement with technical sophistication. The version in black ceramic with diamond & onyx accents elevates the design, giving it an exclusive, high-luxury appeal.

Design and Craftsmanship

The case is made from scratch‑resistant black ceramic (likely ATZ or a high‑grade ceramic variant) giving a bold, matte contrast to the dial. The skeleton dial features diamonds and onyx accents precious stones that lend depth, contrast, and glamour to the openworked architecture. The bezel and inner components may include rose gold or precious metal touches (some variants have gold side elements) to break up the darkness.

Movement and Performance

Underneath the dial is the automatic Calibre CRMA1 (or its variant) — a skeletonized movement with a 50‑hour power reserve and a variable-geometry rotor. The movement includes an oversized date display (located under 12 o’clock) and a function selector (to switch between winding, neutral, and hand-setting modes). The baseplate and bridges are made from Grade 5 titanium, micro-blasted and electroplasma treated for rigidity and precision.
