Yeah, is something to do with the watch movement being battery powered but the chronograph being mechanical (but still powered by the quartz movement)
All marketing bullshit, I'm sure
It's a tuning fork watch, tuning fork vibrates at 300hz regulating the watch. When it's powered up you can hear a faint ring coming from the movement, like have a mosquito in there, but not an annoying one.
Rad - I'm a sucker for an orange seconds hand.
What's MECA-Q? Some kind of mechanical/quartz hybrid?
