The new Richard Mille RM 40-01 Automatic Tourbillon McLaren Speedtail was released yesterday and here’s the assembly process of its impressive calibre CRMT4. This movement is an automatic winding tourbillon movement with hours, minutes, variable-geometry rotor, oversize date, power reserve indicator, and function selector. The entirely new automatic movement architecture demanded a remarkable 8,600 hours of development, much of which went into finalizing the extreme level of detail.
