TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE EXTRA FLAT AUTOMATIC RM 033
CALIBER RMXP1: Skeletonized automatic winding movement with hours, minutes and monoblock platinum rotor
Diameter: 45.70 mm x 6.30 mm.
MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
FREE SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and also during movement assembly and disassembly. Hence better chronometric results over time.
The regulator index is eliminated and a more accurate and repeatable adjustment is possible thanks to 4 adjustable small weights located directly on the balance.
MONOBLOCK MICRO ROTOR
After the rotor with variable geometry that contributed to the success of Richard Mille’s automatic calibres, a new winding device is introduced in the RM033. By using a platinum, decentrally positioned micro rotor, the barrel can be efficiently wound and an extra flat skeletonzied movement can be achieved.
POWER RESERVE: 42 hours
BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM
The baseplate and the skeletonized bridges were first subjected to separate and extensive validation tests to insure optimal strength requirements before manufacturing. The creation of these components in grade 5 titanium with Titalyt® coating for the baseplate and PVD coating for the bridges, allows the whole assembly to be given great rigidity, as well as precise surface flatness that is essential for the perfect functioning of the gear train.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES
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.

CASE
It retains the same characteristics and attention to detail of case design with a vast number of stamping and machining operations required for this round case with a total height comprising a mere 6.30 mm.
The design and execution of this watchcase typifies the complete conceptual approach to all parts of the movement, case and dial. As a result, everything has been constructed according to an extremely rigorous specification. For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws
The tripartite case is assembled with 16 spline screws in grade 5 titanium and abrasion resistant washers in steel and complemented by the additional integration of the lugs into the case’s torque screw system
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE 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.
