Some 3D renders of the movement - still shown in prototype stage, but the production movements will be finished to an even higher level. The microrotor by the way isn't steel but tungsten, apparently a semi-precious metal and one whose density suits its use for the microrotor. The plat watches will carry 24k gold rotors though.
Tungsten is super cheap (dollar-wise, not quality-wise). But it is a good gold substitute.
