Beneath the surface of the world’s deepest oceans and within the soaring vaults of gothic architecture lies the inspiration for Richard Mille’s most hypnotic creation yet: the RM 75-01 Flying Tourbillon Sapphire — a sculptural triumph where transparency becomes emotion.

In a debut that feels almost metaphysical, Richard Mille designs a movement from the ground up for sapphire — exploiting the material’s crystalline mystery and its dizzying technical challenges. Formed through thousands of hours of precision machining, the tripartite sapphire case feels like a jewel in motion: smooth to the touch, impossibly luminous, and defiant in its resistance to scratches. It is a watch that looks as though it emerged fully formed from the sea’s hidden cathedrals.


Three ethereal expressions play with aquatic atmospheres. One shines in full clear sapphire with a wave-like case and sea-green strap — a vision of tropical shores. The other two, each limited to just 10 pieces, layer clear sapphire with dream-washed hues: twilight lilac-pink and abyssal sapphire-blue, evoking the shifting moods of open water.

Inside, a fully skeletonised calibre rises like a vaulted dome, supported by microblasted red-gold pillars and satin-polished titanium — a mechanical cathedral illuminated with Super-LumiNova detailing that glows like phosphorescence in darkness. With its architectural balance of volume, air, and negative space, the flying tourbillon appears as if suspended in liquid light.
A watch of radical clarity and poetic engineering, the RM 75-01 doesn’t merely tell time — it reveals what lies beyond the visible. In every shimmering angle, Richard Mille opens a new horizon where innovation and beauty converge in breathtaking transparency.
