The heart of the timepiece, a skeletonized automatic-winding movement, the caliber RMXP1, is just 2.6mm thick, while the case is 6.3mm deep.
To come up with a remarkably thin movement, the watchmakers positioned the automatic-winding micro rotor off-center. The rotor is crafted in solid platinum and has bi-directional winding.
The 29-jewel movement, operating at the frequency of 21,600 vibrations per hour, offers 42 hours of power reserve. It incorporates a free sprung balance with variable inertia for enhanced reliability when subjected to shock and enhanced chronometric results over time. There are four small adjustable weights found directly on the balance to allow more accurate and repeatable adjustment.
The bottom plate, bridges and balance cock of the movement are crafted from grade 5 titanium. The Richard Mille watchmakers used this material with Titalyt treatment for the bottom plate and black PVD-coating for the bridges to come up with rigidity and precise surface flatness, this way reaching perfect gear train functioning and stability of the movement. They subjected the baseplate and all titanium parts for individual tests to guarantee optimal strength.
The titanium version of the Richard Mille Caliber Extra Flat Automatic RM 033 watch is expected to be available at the price of $70,000, the red gold version at $85,000, and the white gold version at $90,000.
