Richard Mille cuts sapphire into clear, pink, and blue cases, giving the RM 75-01 tourbillon daylight on the wrist.
Richard Mille lets sapphire do the talking in its latest RM 75-01 Flying Tourbillon trio. The clear-walled timepieces put their skeleton cores on stage while paying quiet tribute to both cathedral arches and breaking waves.
First comes the crystal-clear interpretation, paired with a sea-green strap that nods to tropical shallows. Light pours through every surface, giving the flying tourbillon the kind of visibility usually reserved for museum showcases.
Alongside it stand two moodier takes. One frames the movement in lilac-pink sapphire, a shade the maison links to South Sea twilight; the other leans into deep sapphire blue, mirroring ocean trenches. Both watches keep their bezels transparent while tinting the caseback, so colour glows against the wrist rather than shouting from the front.
The RM 75-01 calibre itself remains untouched—fully skeletonised and floating between gothic-inspired bridges. SuperLuminova accents trace key elements, turning the mechanism into a lantern after dusk and throwing sharp shadows across its polished angles.
Building a single case asks for more than 1,000 hours of machining, milling, and hand finish. Sapphire’s hardness keeps scratches at bay but punishes every tool that meets it; the result is a three-piece shell that can be studied from almost any viewpoint.
By pairing that stonework with references drawn from water and architecture, Richard Mille shows that technical watchmaking needn’t wear a sober suit. The RM 75-01 Flying Tourbillon Sapphire trio reads like jewellery, performs like engineering, and—thanks to full transparency—never hides the effort behind the spectacle.
