Uniquely appealing, technically complex and universal, the RM 74-01 and RM 74-02 offer two unique versions of Richard Mille's in-house automatic tourbillon calibre.

These two striking models are distinguished by the materials applied in their cases and movements, resulting in fraternal twins with unique personalities.

They are both driven by the automatic winding in-house calibre CRMT6, which has a power reserve of 50 hours. The movement is visible through sapphire crystals, allowing the wearer to admire the intricate inner workings of the watch, such as the controlled rotation of the variable geometry rotor and the central involute profile going train as well as the variable inertia balance tourbillon pulsations.
