Overview
A monochrome grey case with polished bevelled edges
The case reads grey throughout — a sandblasted bezel whose only relief is the polished bevelling along its edges, a grey caseband and a black chapter ring around the dial periphery. The strap is grey rubber with the louvered profile Richard Mille uses across the sports references, and the seconds hand is tipped in red.
Inside is the calibre RMUL2, a manual-winding skeletonised movement in grade 5 titanium, running 55 hours on a double barrel.
Key details
Design and engineering
- Calibre RMUL2Manual winding and extremely skeletonised, in grade 5 titanium with PVD and Titalyt® treatment, giving rigidity and the surface flatness the gear train needs.
- Free-sprung balance with variable inertiaThe regulator index is eliminated; four small weights set directly on the balance allow accurate and repeatable adjustment.
- Double barrelEnergy is spread across two barrels, equalising torque and reducing pressure and friction on bearings and pivots.
- Rubberised titaniumRubber is injected at high pressure around the titanium components, insulating the movement from vibration and making the watch more comfortable on the wrist.
- Supporting columns in the case wallsA structural feature of the RM 055 case, visible at the flanks.
- Curved sapphire crystalWith a sapphire caseback.
