MovementCalibre RMUL2, manual winding, skeletonised
Design and engineering
- Calibre RMUL2A manual winding skeletonised movement indicating hours, minutes and seconds. The baseplate and bridges are grade 5 titanium, PVD- and Titalyt®-treated, a combination Richard Mille specifies for rigidity and for the surface flatness the going train requires.
- Shock resistanceSpecified by Richard Mille at over 500 g.
- Free-sprung variable-inertia balanceThe regulator index is eliminated. Rate adjustment is made by four small weights mounted directly on the balance, which Richard Mille specifies for repeatability of setting and for reliability through shock, assembly and disassembly.
- Double-barrel systemStored energy is distributed across two winding barrels rather than one. This increases the number of barrel rotations and reduces pressure on teeth, bearings and pivots, and supports the circa 55-hour power reserve.
- Three-part tonneau caseThe three-part tonneau case is assembled with grade 5 titanium spline screws and abrasion-resistant 316L stainless steel washers, with sapphire crystals front and back.
