Overview
Mid-tier setting on a red gold case
The mid setting places round diamonds in bands across the upper and lower bezel and along the case sides, between the full coverage of card 455 and the unset case of card 454. Red gold remains visible as framing, and the case screws sit proud of the stones. The strap is black rubber.
Mid setting is a point on the coverage scale in Richard Mille’s own terminology, alongside unset, one row and full. It is not a technique or a cut, which is the distinction that separates it from the snow, princess-cut and baguette executions elsewhere in the catalogue.

Design and engineering
- Calibre CRMA6Skeletonised automatic winding movement with hours, minutes, date and function indicator. It measures 29.10 × 31.25 mm with a thickness of 3.60 mm, runs on 25 jewels at 28,800 vph (4 Hz) and provides around 50 hours (± 10%) of power reserve.
- Mid settingRound stones are set in bands across the upper and lower bezel and along the case sides, with the metal left visible as framing between the bands and around the case screws.
- Baseplate and bridgesGrade 5 titanium. The baseplate is microblasted with a grey electroplasma treatment; the bridges are microblasted and black electroplasma treated, which Richard Mille records as a first for the brand.
- Platinum rotorA platinum rotor on the OneWay® winding system with ceramic ball bearings, which allows the barrel to be wound efficiently while keeping the movement’s compact dimensions.
- Semi-instantaneous date and function indicatorA semi-instantaneous date in a vertical aperture at 5 o’clock, with a hand at 2 o’clock showing the crown’s position: W for winding, D for date setting, H for hand setting.
- NumeralsSolid metal, mounted on two linked and rigid titanium rails attached directly to the movement, giving depth across the openwork dial.
