A SYNERGETIC APPROACH
Airbus is a name that requires no introduction as a world leader in the application of novel approaches to aeronautical design, in particular those aircraft created for personal clients by its ultra-luxury subsidiary, Airbus Corporate Jets, or ACJ. It was thus only natural that Richard Mille and ACJ joined forces to realise this horological masterpiece inspired by their respective worlds.
RM 50-02 TOURBILLON ACJ
This indicator supplies information about mainspring’s tension, thus permitting optimisation of the movement’s chronometric functioning. Below 5.3 N.mm, the spring is considered too slack, while above 6.5 N.mm, excess tension in the spring can adversely affect the mechanism’s operation, or actually endanger it.
Located on a scale at 11 o’clock, the power-reserve indicator shows the number of hours of energy left in the mainspring before the watch must be wound again.

CASE IN TITANIUM-ALUMINIUM
The highly distinctive and novel case shape, realised in a titanium-aluminium alloy (TiAl) with a secondary bezel in white ATZ ceramic was developed to mirror the outlines of an ACJ’s typical window shape, with a clearly visible, multi-layered hull structure surround. Titanium-aluminide, an intermetallic alloy, has characteristics that stand between metals and ceramics, with physical properties characteristic of a metal and mechanical properties resembling ceramic. It exhibits an extreme rigidity and is much lighter than classical titanium alloys. It is the same alloy used in the Airbus for its jet turbine blades.
