Overview
A gold skull against black ceramic
Where the RM 052 leaves the skull in grade 5 titanium, the RM 52-01 sculpts it in gold and hand-bevels it. This execution sets a yellow-toned gold skull against a black ceramic case and a black rubber strap, with the jaws holding the ruby of the tourbillon cage.
The calibre RM052 is manual winding, with hours and minutes and around 48 hours of reserve from a fast-rotating single barrel.

Design and engineering
- Sculpted gold skullHand-bevelled, and structural — the skull performs the function of baseplate and bridges.
- Jaws and tourbillonThe upper and lower jaws grip the ruby of the tourbillon cage, so the escapement sits in the skull’s mouth.
- Four connecting bridgesRunning from the movement to the caseband, in the arrangement Richard Mille likens to crossed bones.
- TZP ceramic bezel and casebackMicroblasted with hand-polished corners, exploiting the material’s pronounced grain.
- PVD-treated grade 5 titanium baseplateApproved only after a range of tests, giving rigidity and flat surfaces.
- Torque-limiting crownDLC treated, guarding against overwinding.
