Overview
Clear sapphire over a lilac lower bezel
The lilac execution pairs a clear sapphire upper bezel and caseband with a lower bezel in lilac pink sapphire, which Richard Mille relates to twilight over calm water. The red gold flange and the skeletonised movement read through the case, the crown is gem-set on an orange collar, and the strap is pink rubber. Limited to 10 pieces.
The RM 75-01 Flying Tourbillon Sapphire was introduced in April 2025 as three limited editions. Richard Mille made its first all-sapphire case in 2012; what is new here is that the movement was conceived FOR the sapphire case from the start rather than adapted to it. Cécile Guenat’s team drew on Gothic ribbed vaults for the structure and on water for the colours.

Design and engineering
- Calibre RM75-01Manual winding flying tourbillon movement with hours and minutes, running at 21,600 vph (3 Hz) with around 65 hours (± 10%) of power reserve.
- Coloured sapphireGrown by introducing metallic oxides into the crystal structure, which Richard Mille describes as more delicate than growing clear sapphire: temperature and growth rate must be held precisely or the colour distributes unevenly or bubbles form, and matching colour exactly between blocks remains difficult.
- Flying tourbillon and flying barrelBoth are assembled without upper bridges. Richard Mille specifies the arrangement for weightlessness and for unobstructed visibility through the movement.
- Skeletonised baseplate and bridgesGrade 5 titanium, treated in 5N gold and grey PVD. The multilevel baseplate anchors the wheels, tourbillon and barrel; the wheels are rhodium treated.
- Free-sprung balance with variable inertiaThe regulator index is eliminated in favour of four adjustable screws on the balance.
- Sapphire caseBezel, caseband and caseback are milled from solid blocks of synthetic sapphire, a material second only to diamond in hardness. Richard Mille records over 1,000 hours of machining and polishing per case, of which around 430 hours are preforming and 350 hours polishing, with anti-glare treatment on both faces of the front and back crystals.
- Upper flange5N red gold, microblasted, resting on satin-polished titanium pillars, with polished and microblasted steel markers and luminous index points.
