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 case componentsRubber is injected at high pressure around the titanium components, insulating the movement from vibration and making the watch more comfortable on the wrist.
- Sapphire casebackThe skeletonised calibre is legible from the reverse.
