Overview
The monochrome black treatment
The RM 61-01 Yohan Blake All Black was shown in 2015, replacing the green and yellow of the launch colourway with black across the flange, bridges and hands. Construction is unchanged: bezel and caseback in TZP-N black ceramic with a matte finish, caseband in NTPT® carbon, and the manual winding calibre RMUL2.
The watch is fitted with a white rubber strap. The large drawn-out crown protectors are visible at 3 o’clock; Richard Mille’s stated purpose for them is to keep the crown from rubbing against the wrist at sprinting speed.

Design and engineering
- 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.
- TZP-N ceramicA black ceramic composed of 95% zirconium compound stabilised with yttrium, with a density of 6 g/cm³. Richard Mille specifies it for scratch resistance and a low coefficient of thermal conductivity, finished matte on top with hand-polished bevelled angles at the sides.
- NTPT® carbon casebandMultiple layers of parallel filaments obtained by dividing carbon fibre, consolidated under pressure and machined so that the layer structure is exposed.
- Crown and crown protectorsThe crown is NTPT carbon with an Alcryn collar and a torque-limiting system, flanked by two large protectors that shield it during activity.
- 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.
- Shock resistanceValidation testing carried out in excess of 5,000 g.
