>>>Works at 7g and as I do aeros it makes sense.
Think about that for a moment.
The internal components of any wristwatch have a mass which is trivially small. At, even say, 20g so are any gravitational and inertial forces.
Plus, given the geometry, my wrist probably sees more gs going for a brisk walk than a member of The Blades does whilst flying a display.
Basically, a £5 watch from Argos will be just as able to take aerobatics - possibility better as it has a far lower mass.
