Sapphire and sparkle for Richard Mille's RM 07-02

The very long process of fabrication starts with a detailed study of the sapphire's composition The machining of each piece of extremely hard and resistant sapphire, hone from a giant block, requires 40 days of finishing On top of this, the sapphire's deep structure is also examined so as to achieve the exact tone of pink, green or blue chosen by the brand.

The crystalline hue of the sapphire enhances the subtle alternating rhythm between the brightness of the twelve diamond lines and the brand's emblematic design of the case screws This new case highlights the house's skeletonised movement- in micro blasted grey gold for the green and blue sapphire versions, and in 5N red gold for the pink sapphire Each sapphire colour corresponds to a specific ornamental stone on the dial: nephrite for the green sapphire, motherof- pearl for the blue, and jasper for the pink.

The piece is wound automatically via its variable-geometry rotor in 18K 5N red gold set with diamonds, ensuring that the winding adapts to the movements of the wearer. . Source
