Overview
The Tourbillon Aerodyne in pale blue and white
The RM 21-02 Cotton Candy pairs a pale blue and white case with the Tourbillon Aerodyne’s calibre RM21-02, a manual winding tourbillon.
The calibre and case architecture are those of the RM 21-02: a Carbon TPT® baseplate combined with a honeycombed structure in black-PVD-treated HAYNES 214, with the winding barrel and tourbillon placed centrally on four-armed titanium bridges, and torque, power-reserve and function-selector indications around them.
