Overview
Rows of stones set across a dark bezel
The bezel is set with stones in rows following the case outline, against a dark ground, with the skeletonised calibre RMUL2 and its gold hands and flange markings visible between them. The strap is black rubber.
The RM 055 was engineered for impact rather than display, so a set execution puts the setting on a case designed around supporting columns and rubberised insulation.
Key details
Design and engineering
- Row settingStones laid in continuous rows following the outline of the bezel.
- Calibre RMUL2Grade 5 titanium, extremely skeletonised, PVD and Titalyt® treated.
- 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 movement is legible from the reverse.
