I have a ID107 plus hr and on turned the power off on the watch through the more screen, how do you turn the watch back on?

Hi there! Depends on whether the upgrade is brand new or demo. I would rather go for the latter. $159.99 is not a lot more for an upgrade. If your original purchase did not survive until out of warranty, then it was obviously a dud to start with. The decision still lies with you. Best Wishes and Good Luck, JUS004
