Overview
A red skull in a white ceramic case
The skull here is red, against a white ceramic case with a red crown and a white rubber strap. The colour runs across the cranium and jaws, so the tourbillon cage sits in a red mouth at the lower half of the display.
The calibre RM052 is manual winding, with hours and minutes, a fast-rotating single barrel and around 48 hours of reserve.

Design and engineering
- Coloured skullOne of a small number of colour variations Richard Mille produced for the reference.
- Jaws and tourbillonThe upper and lower jaws grip the ruby of the tourbillon cage, so the escapement sits in the skull’s mouth.
- White ceramic bezel and casebackMicroblasted, with the corners hand polished.
- Openworked constructionThe cut-outs in the bezel and caseback reduce weight and expose the skull from both faces.
- Fast-rotating single barrelDelivering more constant torque than a conventional barrel.
- Torque-limiting crownPreventing overwinding.
