Richard Mille RM 21-02 Tourbillon Aérodyne One Of 50 was Ever Made

Precision, lightness and resistance are intimately bound by materials and architectural constructions.Brand always capitalized on engineering materials from fields way beyond watchmaking.

The RM 21-02 Tourbillon Aerodyne has set the highest limits for watchmaking both in terms of its design, mechanical inventiveness and use of materials.

POWER RESERVE

Around 70 hours (± 10%).

Richard Mille RM 21-02 Tourbillon Aerodyne combines bold design and exceptional materials for a striking look characterized by a case made of Carbon TPT and Green Quartz TPT, two exclusive materials with exceptional physical properties and a distinctive appearance.

Green Quartz TPT is also used for the case back, while the case middle is crafted from satin-finished grade 5 titanium with TPT carbon pillars. The design is enlivened by orange accents.

Measuring 42.68 x 50.12 x 14.30 mm, the three-part case is water-resistant to 50 meters / 165 feet, thanks to two nitrile O-rings. The case is assembled with 20 spline screws in grade 5 titanium and 316L stainless steel anti-abrasion washers.

The power reserve indicator is positioned where the numeral would normally be at 11 o’clock, while the torque indicator is symmetrically placed at 1 o’clock. This allows the wearer to monitor the mainspring tension and thus optimize the movement’s operation. Below 5.3 N.mm, the spring is too loose; at the other extreme, above 6.5 N.mm, excessive tension can impair the movement’s function and even cause damage.

At 4 o’clock, you’ll find the function selector, activated by a pusher integrated into the center of the crown. Pressing it allows you to switch from the Neutral (N) position to Winding (W) or Hand Setting (H).
