Overview
A white case in the green and yellow colourway
The photograph shows an RM 61-01 with a white case, a green inner bezel, a yellow flange and green and yellow bridges, a yellow crown collar and a white rubber strap — the launch colourway carried on a white rather than black case.
Richard Mille’s published material for the RM 61-01 specifies TZP-N, a black ceramic, for the bezel and caseback. The brand’s designation for white ceramic is ATZ, and the two are distinct materials in its own naming. A white RM 61-01 is not covered by the published specification, so the case material is recorded as observed rather than named.

Design and engineering
- What is not establishedRichard Mille specifies TZP-N — a BLACK ceramic — for the RM 61-01’s bezel and caseback, and uses ATZ for white ceramic elsewhere. A white RM 61-01 appears in no brand text found, so no material is entered. Whether a white-cased reference exists or this record carries the wrong photograph is a question the record cannot answer.
- Calibre RMUL2Manual winding skeletonised movement with a power reserve of 55 hours, built on a grade 5 titanium baseplate and bridges treated with PVD and Titalyt®. The movement is 3.15 mm thick, runs on 24 jewels at 28,800 vph (4 Hz), and weighs 4.3 grams.
- Asymmetric caseThe case is drawn out between 2 and 5 o’clock so that the crown does not rub against the wrist, and the left side is lower and thinner than the right.
- Flying bridgesAnodised and hand-painted bridges cross the front of the movement in green and yellow, matching the inner bezel and flange.
- Free-sprung balance with variable inertiaRegulation is by adjustable weights on the balance rather than by a regulator index.
- Crown protectorsTwo large protectors shield the crown, which carries a torque-limiting system against overwinding.
