Another thing on the Ride Watches:

Double pressing the top bottom has a secondary set of sounds. That might be how it temp restores a rider.

Very few have had 'activated ride watches', and the ones that did it was implied they didn't press the top button, let alone double press it. And it'd make sense that Oma Zi-O or future King Zi-O may need a rider's input or counsel, so having a ride watch able to draw on their experiences and knowledge would make sense as well as fits into that Doctor Who pocket watch type reference.
