Richard Mille - RM016

BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM
The manufacture of these components in grade 2 titanium with black PVD coating allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the per-fect functioning of the gear train.

DOUBLE BARREL SYSTEM
The double barrel system helps to improve the stability of torque over a longer period. This is achieved by using more turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance. DATE DISPLAY Semi-instantaneous, placed in a vertical aperture in the numeral 7. The calendar disc of sapphire crystal is treated with non-reflective coating on both sides.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

INTERIOR FLANGE (upper and lower)
In carbon fiber, with index points filled with approved luminous material.

CROWN
In grade titanium, with double seal O-ring and detailing in either 18-carat red or white gold.
