Overview
Mid setting on a white gold case
Round diamonds are set in bands across the upper and lower bezel and along the case sides of a white gold case, with the metal left visible as framing and around the case screws. The numerals are white, the strap black rubber.
This is the white gold counterpart to the red gold mid setting on card 457, and it is close enough to card 459 — labelled TI DIAM — that the two photographs are difficult to separate.

Power reserveAround 50 hours (± 10%)
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. Mid is a coverage tier between unset and full setting.
- 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.
- Fast-rotating barrelOne revolution every five hours instead of seven and a half, which Richard Mille specifies for reduced periodic internal mainspring adhesion and a favourable mainspring delta curve.
- 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.
