Its powerful stature is carved from ultra-light materials: brushed titanium for the 44 mm diameter case, Aeronith for the textured bezel. This lightest aluminium composite in the world was developed using an exclusive high-tech process. Three times lighter than titanium, made of open-pore aluminium foam stiffened with a polymer, Aeronith is easily forgotten when worn, while asserting a unique modern style.

Its properties notably include increased reliability, given that this unique ultra-thin element (0.5 mm) replaces the 30 or so components of a standard regulating organ and thus eliminates contact, friction, wear and deformation; and secondly, stability, since it is made of monocrystalline silicon.
