The flying tourbillon is a complex regulating mechanism, creating the impression of weightlessness, and offering perfect visibility. The delicate petals in 18K gold open and close every five minutes to reveal the flying tourbillon which moves upwards 1 mm when fully opened. The centre of the tourbillon gracing is set with precious stones.

This tripartite tonneau-shaped case is fully curved, which ensures the watch is ergonomic and comfortable.
Both front and back curves are part of the Richard Mille watch case regardless of its shape. The specific tonneau shape requires 47 stamping operations, including 21 for preparation alone. Tooling takes 4 hours, and the RM 19-02 is obtained only after 250 milling operations. The finishing process requires a full day for grinding, glazing and polishing.
Grade 5 titanium is a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automobile industries. The baseplate, entirely hand engraved with a floral pattern, was subjected to intensive and complete validation tests to optimise its resistance capacities.
This additional security system prevents accidental overwinding, which can cause damage to the winding stem or put extreme pressure on the barrel spring.
