Continuing the expansion and application of truly unique materials to watchmaking, the RM 021 is the first watch created with a composite baseplate utilizing a titanium exterior framework in combination with honeycombed orthorhombic titanium alumide and carbon nanofiber.
Richard Mille always dreamt of incorporating a titanium honeycomb structure, a concept traditionally used in aeronautics, and this choice gave a baseplate that was both rigid and very light. The objective was to juxtapose and laser-weld each tiny cell. This achievement on such a microscopic scale is a major technical tour de force in the world of 21st century horology.
FUNCTION SELECTOR In a manner similar to a car's gearbox, a push-button located at the center of the crown allows one to select the winding, neutral and hand setting functions with a simple push. A hand at 4 o’clock displays the selected function: W (Winding) – N (Neutral) – H (Hands).
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.
TORQUE INDICATOR Utilizing a numeric scale located between 12 and 1 o’clock, the indicator provides visualization of the mainspring’s internal tension, allowing optimization of the movement’s timing. Below 53 dNmm, the spring is too slack; at the other extreme, above 65 dNmm, excessive tension can adversely affect the running of the movement and may even cause damage.
