Overview
A composite case replacing the ceramic
The RM 61-01 Ultimate Edition is the final issue of the model. TZP ceramic gives way to Quartz TPT® and Carbon TPT® for the bezel and caseback, with Carbon TPT® also used for the caseband and for the crown protector. The white and black banding of the interleaved composites runs across the case.
The two materials are combined in a single stack: layers of silica-based Quartz TPT® no more than 45 microns thick are interlaced with layers of Carbon TPT®, positioned by an automatic compiling system that rotates the fibre orientation by 45° between plies. The 600-layer stack is cured in an autoclave at 120°C under 6 bar and then machined in-house, so milling and turning expose a pattern that differs on every component.
Key details
Design and engineering
- Interleaved compositeSilica-based Quartz TPT® layers no thicker than 45 microns are stacked alternately with Carbon TPT® layers, each ply rotated 45° from the last, then heated to 120°C at 6 bar in an autoclave before machining at Richard Mille’s own factory.
- CalibreA highly skeletonised movement in PVD-treated grade 5 titanium with a 55-hour power reserve, tested for impacts in excess of 5,000 g.
- Traversing balance bridgesThe balance bridges are grade 5 titanium, black-galvanised and hand-painted.
- Variable-inertia balanceOscillating at 4 Hz, adjusted by weights on the balance rather than by an index.
- Crown protector in Carbon TPT®Protects the crown during activity; the case elongation between 2 and 5 o’clock removes contact with the wrist.
- The last of the modelThis limited edition of 150 pieces brings to a close this model’s 6-year career.
